Startup Finance Glossary
Plain-English definitions of 75+ startup finance and SaaS metrics terms. Formulas and real-world examples included.
SaaS Metrics
Activation Rate
Activation rate is the percentage of new signups who complete a key onboarding milestone that correlates with long-term retention. It bridges the gap between acquisition and engagement, and is the most actionable early-funnel metric for identifying friction in the new-user experience.
Annual Contract Value (ACV)
Annual contract value (ACV) is the average annualized revenue per customer contract, normalized to a one-year period. ACV is used primarily by B2B SaaS companies to measure deal size, compare sales efficiency across segments, and benchmark against industry medians for enterprise versus SMB deals.
Annual Recurring Revenue (ARR)
Annual recurring revenue (ARR) is the annualized value of a company's recurring subscription revenue. Calculated by multiplying MRR by twelve, ARR provides a macro view of revenue scale and is the primary metric investors use when benchmarking SaaS companies above $1 million in revenue.
Average Revenue Per User (ARPU)
Average revenue per user (ARPU) is the mean recurring revenue generated per active customer account over a given period, typically calculated monthly. ARPU helps SaaS companies evaluate pricing effectiveness, segment customers by value, and forecast revenue from their existing user base.
Contraction Revenue
Contraction revenue, or contraction MRR, is the reduction in recurring revenue from existing customers who downgrade their plans, remove seats, or reduce usage. Tracking contraction separately from churn helps SaaS companies distinguish between customers leaving entirely and those reducing their commitment.
Customer Churn Rate
Customer churn rate is the percentage of customers who cancel or stop using a service during a given time period. It is one of the most critical health indicators for subscription businesses, directly impacting growth projections, customer lifetime value, and long-term revenue sustainability.
Daily Active Users / Monthly Active Users (DAU/MAU)
DAU and MAU measure the number of unique users who engage with a product daily and monthly, respectively. The DAU/MAU ratio, also called the stickiness ratio, reveals how frequently users return and is a leading indicator of engagement, retention, and long-term product-market fit.
Expansion Revenue
Expansion revenue is additional recurring revenue earned from existing customers through upsells, cross-sells, add-ons, or seat-based growth. It is a key driver of net revenue retention and allows SaaS companies to grow revenue from their installed base without acquiring new customers.
Gross Revenue Retention (GRR)
Gross revenue retention (GRR) measures the percentage of recurring revenue retained from existing customers over a given period, excluding any expansion revenue. GRR can never exceed 100 % and isolates how well a company prevents downgrades and cancellations from its installed base.
Monthly Recurring Revenue (MRR)
Monthly recurring revenue (MRR) is the predictable, normalized revenue a subscription business earns every month. It includes all active subscriptions converted to a monthly value, excluding one-time charges, and serves as the core growth metric for SaaS companies.
Net Revenue Retention (NRR)
Net revenue retention (NRR), also called net dollar retention (NDR), measures the percentage of recurring revenue retained from existing customers over a period, including expansions, contractions, and churn. An NRR above 100 % means a company grows even without acquiring new customers.
Revenue Churn Rate
Revenue churn rate measures the percentage of monthly recurring revenue lost due to cancellations and downgrades during a specific period. Unlike customer churn rate which counts logos, revenue churn weights each lost customer by their subscription value, giving a more accurate picture of financial impact.
Financial Fundamentals
Balance Sheet
A balance sheet is a financial statement that reports a company's assets, liabilities, and shareholders' equity at a specific point in time. It provides a snapshot of what a company owns, what it owes, and the residual value belonging to owners, following the fundamental equation: Assets = Liabilities + Equity.
Burn Rate
Burn rate is the speed at which a startup spends its cash reserves, typically expressed as a monthly figure. Gross burn rate is total monthly cash spending, while net burn rate subtracts revenue, showing the actual monthly cash deficit the company must fund through its remaining capital.
Capital Expenditure (CapEx)
Capital expenditure (CapEx) refers to funds spent by a business to acquire, upgrade, or maintain long-term physical or intangible assets such as equipment, property, or software. Unlike operating expenses, CapEx is capitalized on the balance sheet and depreciated over the asset's useful life.
Cash Flow
Cash flow is the net movement of money into and out of a business over a specific period. Positive cash flow means more money is coming in than going out, while negative cash flow indicates spending exceeds income. It is distinct from profit because it accounts for timing of actual payments.
Depreciation & Amortization
Depreciation and amortization are accounting methods for spreading the cost of an asset over its useful life. Depreciation applies to tangible assets like equipment and furniture, while amortization applies to intangible assets like patents and capitalized software development costs.
EBITDA
EBITDA stands for Earnings Before Interest, Taxes, Depreciation, and Amortization. It measures a company's core operating profitability by stripping out financing decisions, tax structures, and non-cash accounting charges, making it a widely used metric for comparing operational performance across companies.
Gross Profit
Gross profit is the revenue remaining after subtracting the cost of goods sold (COGS), representing the money available to cover operating expenses, debt service, and generate net profit. It measures how efficiently a company produces and delivers its product or service relative to the revenue it generates.
Net Income
Net income, also known as the "bottom line," is the total profit remaining after all expenses, interest, taxes, and non-operating costs are subtracted from revenue. It represents the actual earnings available to shareholders and is the ultimate measure of a company's profitability.
Operating Expenses (OpEx)
Operating expenses (OpEx) are the ongoing costs a business incurs through normal operations, excluding cost of goods sold. For startups, OpEx typically includes salaries, rent, software subscriptions, marketing spend, and administrative costs, everything required to run the business beyond producing the product itself.
Profit and Loss Statement (P&L / Income Statement)
A profit and loss statement (P&L), also called an income statement, summarizes a company's revenues, costs, and expenses over a specific period to show whether the business earned a profit or incurred a loss. It is one of the three core financial statements used to evaluate business performance.
Revenue
Revenue is the total income a business earns from its primary operations: selling products or services, before deducting any costs or expenses. Also called the "top line," revenue is the starting point for all profitability calculations and the most fundamental measure of business scale.
Runway
Runway is the number of months a startup can continue operating before its cash runs out, calculated by dividing current cash reserves by the monthly net burn rate. It is the most critical financial planning metric for early-stage companies and directly determines fundraising timelines.
Unit Economics
Break-Even Point
The break-even point is the level of sales at which total revenue exactly equals total costs, resulting in zero profit or loss. Knowing the break-even point helps startups understand the minimum sales volume or revenue needed to cover all fixed and variable costs before generating any profit.
CAC Payback Period
The CAC payback period is the number of months it takes for a company to recover the cost of acquiring a customer through that customer's gross margin contribution. A shorter payback period means faster capital recycling and less risk, with under 12 months considered strong for SaaS businesses.
Contribution Margin
Contribution margin is the revenue remaining after subtracting variable costs directly associated with producing and delivering a product or service. Expressed as a dollar amount or percentage, it shows how much each unit sold contributes toward covering fixed costs and generating profit.
Customer Acquisition Cost (CAC)
Customer acquisition cost (CAC) is the total cost of acquiring a new paying customer, including all sales and marketing expenses divided by the number of new customers gained in a period. CAC determines pricing floors, marketing budget allocation, and overall business model viability.
Customer Lifetime Value (LTV / CLV)
Customer lifetime value (LTV or CLV) is the total revenue a business expects to earn from a single customer over the entire duration of their relationship. LTV is essential for determining how much a company can afford to spend acquiring customers while maintaining profitability.
Gross Margin
Gross margin is gross profit expressed as a percentage of revenue, showing how much of each revenue dollar remains after covering the direct costs of delivering the product or service. SaaS companies typically have gross margins of 70-85 %, reflecting the low marginal cost of software delivery.
LTV to CAC Ratio
The LTV to CAC ratio compares the lifetime value of a customer to the cost of acquiring them. A ratio of 3:1 is considered the benchmark for healthy SaaS economics, meaning each customer generates three times more value than the cost to acquire them, leaving room for operating costs and profit.
Net Margin
Net margin, also called net profit margin, is net income expressed as a percentage of revenue. It represents the ultimate profitability of a business after all costs (COGS, operating expenses, interest, and taxes) have been deducted, showing how many cents of profit remain from each dollar earned.
Operating Margin
Operating margin is operating income (revenue minus COGS and operating expenses) expressed as a percentage of revenue. It measures how efficiently a company turns revenue into profit from its core operations, excluding the effects of financing, taxes, and non-operating items.
Unit Economics
Unit economics is the analysis of revenue and costs associated with a single unit of a business model, typically one customer or one transaction. Positive unit economics means each customer generates more revenue than they cost to acquire and serve, which is a prerequisite for sustainable scaling.
Fundraising & Equity
Angel Investor
An angel investor is a high-net-worth individual who provides early-stage capital to startups in exchange for equity or convertible instruments, typically investing between $10,000 and $250,000. Angels often invest at the pre-seed or seed stage and may also provide mentorship, industry connections, and strategic advice.
Cap Table (Capitalization Table)
A cap table (capitalization table) is a detailed record of a company's equity ownership structure, listing all shareholders, their share counts, ownership percentages, and the terms of their equity instruments. It is the definitive document for tracking how ownership evolves through fundraising rounds and option grants.
Convertible Note
A convertible note is a short-term debt instrument that converts into equity during a future financing round, typically at a discounted price. Unlike SAFEs, convertible notes accrue interest and have a maturity date, creating a legal obligation for repayment if conversion does not occur before the note matures.
Due Diligence
Due diligence is the comprehensive investigation an investor conducts before finalizing an investment, examining a startup's financials, legal standing, technology, team, market, and customer base. It typically occurs between signing a term sheet and closing the round and can take two to six weeks.
Equity Dilution
Equity dilution occurs when a company issues new shares, reducing existing shareholders' ownership percentage. Dilution happens during fundraising rounds, employee stock option grants, and SAFE/convertible note conversions. While dilution decreases percentage ownership, it ideally increases the absolute value of each stakeholder's shares.
Post-Money Valuation
Post-money valuation is the estimated value of a company immediately after receiving a new round of investment, calculated by adding the investment amount to the pre-money valuation. It represents the total enterprise value including newly invested capital and directly determines each investor's ownership percentage.
Pre-Money Valuation
Pre-money valuation is the estimated value of a company immediately before receiving a new round of investment. It establishes the price per share at which new investors buy in and, together with the investment amount, determines how much ownership the new investors will receive.
SAFE Agreement (Simple Agreement for Future Equity)
A SAFE (Simple Agreement for Future Equity) is an investment instrument created by Y Combinator that gives investors the right to receive equity in a future priced round. SAFEs have no maturity date, interest rate, or repayment obligation, making them the most common fundraising instrument for pre-seed and seed-stage startups.
Series A / B / C Funding Rounds
Series A, B, and C refer to successive rounds of venture capital financing that startups raise as they scale. Each round is named after the class of preferred stock issued and typically corresponds to a growth stage: Series A for product-market fit, Series B for scaling, and Series C for market dominance or pre-IPO growth.
Term Sheet
A term sheet is a non-binding document outlining the key financial and governance terms of a proposed investment, including valuation, investment amount, liquidation preferences, board composition, and protective provisions. It serves as the basis for negotiation before detailed legal documents are drafted.
Venture Capital (VC)
Venture capital (VC) is a form of private equity financing provided by institutional firms to high-growth startups in exchange for equity ownership. VC firms raise funds from limited partners and deploy capital across a portfolio of companies, typically expecting outsized returns from a small number of breakout successes.
Vesting Schedule
A vesting schedule is the timeline over which an individual earns full ownership of granted equity or stock options. The standard startup vesting schedule is four years with a one-year cliff, meaning no equity vests in the first year, followed by monthly or quarterly vesting for the remaining three years.
Accounting & Tax
Accounts Payable (AP)
Accounts payable (AP) represents the money a company owes to its suppliers, vendors, and service providers for goods or services received but not yet paid for. AP is recorded as a current liability on the balance sheet and must be managed carefully to maintain vendor relationships and optimize cash flow timing.
Accounts Receivable (AR)
Accounts receivable (AR) represents money owed to a company by its customers for products or services already delivered but not yet paid for. AR is recorded as a current asset on the balance sheet and directly impacts cash flow, as high receivables mean revenue has been earned but cash has not yet been collected.
Accrual Accounting
Accrual accounting records revenue when earned and expenses when incurred, regardless of when cash actually changes hands. This method provides a more accurate picture of financial performance over time than cash-basis accounting and is required under GAAP for companies above a certain size.
Cash Basis Accounting
Cash basis accounting records revenue when cash is received and expenses when cash is paid, regardless of when goods or services are actually delivered. It is simpler than accrual accounting and common among very small businesses, but it can distort financial performance for subscription companies.
Cost of Goods Sold (COGS)
Cost of goods sold (COGS) represents the direct costs attributable to producing or delivering a company's product or service. For SaaS companies, COGS typically includes hosting infrastructure, payment processing fees, customer support, and third-party software costs that scale directly with usage or customer count.
Days Sales Outstanding (DSO)
Days sales outstanding (DSO) measures the average number of days it takes a company to collect payment after a sale is made. A lower DSO indicates faster cash collection and healthier cash flow, while a rising DSO may signal collection issues or overly lenient credit terms with customers.
Fiscal Year
A fiscal year is the 12-month period a company uses for financial reporting and tax purposes. While many startups use the calendar year (January to December), companies can choose any 12-month period as their fiscal year to better align with their business cycle or operational patterns.
R&D Tax Credit
The R&D tax credit is a federal and state tax incentive that allows companies to reduce their tax liability based on qualified research and development expenditures. Startups spending on software development, algorithm design, and technical experimentation can often claim significant credits even before generating taxable income.
Sales Tax Nexus
Sales tax nexus is the connection between a business and a state or jurisdiction that triggers an obligation to collect and remit sales tax. For SaaS companies, nexus can be established through physical presence, employee location, or exceeding economic thresholds (typically $100,000 in sales) in a given state.
Working Capital
Working capital is the difference between a company's current assets and current liabilities, measuring its ability to fund day-to-day operations and meet short-term obligations. Positive working capital indicates a company can cover its near-term debts, while negative working capital may signal liquidity issues.
Business Operations
Accounts Reconciliation
Accounts reconciliation is the process of comparing two sets of financial records, typically internal books against external statements like bank records or payment processor reports, to ensure they match and to identify and resolve any discrepancies. Regular reconciliation prevents errors from compounding.
Budget Variance
Budget variance is the difference between budgeted (planned) amounts and actual results for a given period, expressed in dollars or as a percentage. Analyzing variances helps companies identify areas where spending or revenue deviates from plan, enabling timely corrective action and more accurate future budgeting.
Cash Reserve
A cash reserve is money set aside by a business to cover unexpected expenses, revenue shortfalls, or emergency situations. Maintaining an adequate cash reserve protects startups from cash flow disruptions and provides a buffer that prevents reactive decision-making during temporary downturns.
Chart of Accounts
A chart of accounts is the organized listing of every account in a company's general ledger, categorized into assets, liabilities, equity, revenue, and expenses. It serves as the structural framework for all financial recording and reporting, and a well-designed chart of accounts makes financial analysis and tax preparation significantly easier.
Consolidated Financial Statements
Consolidated financial statements combine the financial results of a parent company and its subsidiaries or related entities into a single set of reports. They eliminate inter-entity transactions and present the group's overall financial position as if it were a single economic entity.
Deferred Revenue
Deferred revenue is money received from customers for services or products not yet delivered, recorded as a liability on the balance sheet. For SaaS companies, deferred revenue arises when customers prepay for annual or multi-year subscriptions, and it converts to recognized revenue as the service is provided over time.
Financial Forecast
A financial forecast is a projection of a company's future financial performance based on historical data, growth assumptions, and planned initiatives. It typically covers revenue, expenses, cash flow, and key metrics for 12–36 months and is essential for fundraising, budgeting, and strategic decision-making.
Invoice Factoring
Invoice factoring is a financing arrangement where a business sells its outstanding invoices (accounts receivable) to a third-party factor at a discount in exchange for immediate cash. It provides faster access to working capital without taking on traditional debt, typically advancing 80-90 % of invoice value upfront.
Multi-Entity Management
Multi-entity management is the practice of overseeing financial operations across multiple legal entities, subsidiaries, or business units from a unified system. It enables founders and operators to track revenue, expenses, and performance separately for each entity while maintaining a consolidated view of the overall business.
Revenue Recognition
Revenue recognition is the accounting principle that determines when and how revenue is recorded in a company's financial statements. Under ASC 606 and IFRS 15, revenue is recognized when a performance obligation is satisfied, meaning the product or service has been delivered, not necessarily when payment is received.
Growth & Strategy
Burn Multiple
Burn multiple is the ratio of net cash burned to net new annual recurring revenue (ARR) generated, measuring how efficiently a startup converts spending into revenue growth. A burn multiple below 1.5x is excellent, 1.5–2x is good, and above 2x suggests the company is spending too much relative to its growth rate.
Compound Monthly Growth Rate (CMGR)
Compound monthly growth rate (CMGR) is the average month-over-month growth rate that would take a metric from its beginning value to its ending value over a given period. It smooths out month-to-month volatility and provides a cleaner measure of sustained growth than simple averaging.
North Star Metric
A north star metric is the single metric that best captures the core value a product delivers to its customers. It aligns the entire company around one measurable outcome that drives sustainable growth, serving as the primary focus for product, engineering, marketing, and sales teams when prioritizing work.
Product-Market Fit
Product-market fit (PMF) is the stage at which a product satisfies strong market demand, evidenced by organic growth, high retention, and customers who would be very disappointed if the product disappeared. It is the most important milestone for early-stage startups and a prerequisite for scalable growth.
Rule of 40
The Rule of 40 is a SaaS performance benchmark stating that a company's revenue growth rate plus its profit margin should equal or exceed 40 %. It balances the tradeoff between growth and profitability, recognizing that high-growth companies can sacrifice margins while profitable companies can accept slower growth.
SaaS Magic Number
The SaaS Magic Number measures sales efficiency by comparing new recurring revenue generated to the sales and marketing spend required to generate it. A magic number above 0.75 suggests it is efficient to increase sales spending, while below 0.5 indicates the go-to-market engine needs optimization before scaling.
SaaS Quick Ratio
The SaaS Quick Ratio measures revenue growth efficiency by comparing the total MRR added (new + expansion + reactivation) to the total MRR lost (contraction + churn). A quick ratio above 4 is considered excellent, meaning the company adds four dollars of revenue for every dollar lost, indicating strong and sustainable growth.
Serviceable Addressable Market (SAM)
Serviceable addressable market (SAM) is the portion of the total addressable market that a company can realistically target with its current product, business model, and geographic reach. SAM narrows TAM to the segment that the company can actually serve, providing a more practical view of near-term revenue potential.
Total Addressable Market (TAM)
Total addressable market (TAM) is the total revenue opportunity available if a product achieved 100 % market share in its target segment. TAM quantifies the maximum revenue ceiling for a business and is a key component of investor pitch decks, used to assess whether a market is large enough to support a venture-scale outcome.
