7 Financial KPIs to Review Weekly as a Small Biz
78% of failed small businesses cite cash flow issues. Track these 7 weekly KPIs to catch problems early -- with benchmarks, formulas, and a 15-minute review process.
78% of small businesses that fail cite cash flow problems as a primary cause. The pattern is almost always the same: they reviewed their numbers monthly or quarterly, and by the time they spotted the problem, it was too late to fix. Weekly KPI reviews catch issues when they are still manageable -- when you have weeks to course-correct instead of days.
You do not need to track 50 metrics weekly. You need seven. These seven KPIs give you a complete picture of your financial health in 15 minutes. If all seven are green, you can focus on building. If any one turns red, you know exactly where to dig in.
The 7 Weekly KPIs
1. Cash Balance and Burn Trajectory
What it measures: How much cash you have and how fast it is decreasing.
Formula: Current bank balance / average weekly net burn = weeks of runway remaining
Weekly check: Log your bank balance every Monday morning. Compare it to last Monday. Calculate the weekly burn (last Monday's balance minus this Monday's balance plus any revenue received).
| Health Status | Runway Remaining | Action |
|---|---|---|
| Green | 6+ months | Continue as planned |
| Yellow | 3-6 months | Begin cost optimization, consider fundraising |
| Red | Under 3 months | Immediate cost cuts, emergency fundraising |
This is the single most important number for survival. Everything else is secondary if you are running out of cash. Model different scenarios with a burn rate calculator to understand how hiring decisions and revenue changes affect your trajectory.
2. Weekly Revenue (or Bookings)
What it measures: How much new revenue you generated this week.
Formula: Sum of all new revenue recognized or bookings closed in the 7-day period
Weekly check: Track actual revenue against your weekly target. Calculate the 4-week moving average to smooth out weekly volatility.
| Metric | Benchmark |
|---|---|
| Week-over-week growth (early stage) | 3-7% |
| Week-over-week growth (scaling) | 1-3% |
| Revenue vs. weekly target | 90-110% on track |
| 4-week trend | Should be flat or increasing |
A single bad week means nothing. Two bad weeks in a row deserve investigation. Three consecutive bad weeks signal a real problem that needs immediate attention.
3. Accounts Receivable Aging
What it measures: How much money customers owe you and how long they have owed it.
Formula: Break receivables into buckets: current (0-30 days), 31-60 days, 61-90 days, 90+ days
Weekly check: Review total AR balance and the percentage in each aging bucket. Flag any customer whose balance moved from one bucket to the next.
| AR Age | Benchmark (% of total AR) | Collection Probability |
|---|---|---|
| Current (0-30 days) | 70-80% | 95%+ |
| 31-60 days | 10-15% | 85-90% |
| 61-90 days | 5-8% | 70-80% |
| 90+ days | Under 5% | 50% or less |
If more than 20% of your AR is over 60 days, you have a collections problem that is silently eating your cash flow.
4. Weekly Cash Inflows vs. Outflows
What it measures: The timing match between money coming in and money going out.
Formula: Total cash received this week minus total cash spent this week
Weekly check: Compare the ratio of inflows to outflows. Ideally, weekly inflows cover at least 70-80% of weekly outflows for a pre-profit company, or exceed outflows for a profitable one.
| Status | Inflow/Outflow Ratio | Interpretation |
|---|---|---|
| Cash positive | Over 1.0 | Growing cash balance |
| Near breakeven | 0.8 - 1.0 | Sustainable with runway |
| Burning moderately | 0.5 - 0.8 | Monitor closely |
| Burning fast | Under 0.5 | Revenue much lower than spend |
Track this weekly to catch seasonal dips, payment delays, or accelerating expenses before they become critical.
5. Gross Margin
What it measures: How much profit you keep from each dollar of revenue after direct costs.
Formula: (Revenue - Cost of Goods Sold) / Revenue x 100
Weekly check: Calculate gross margin on the trailing 4-week basis. Flag any week where margin drops more than 5 percentage points from the average.
| Business Type | Target Gross Margin | Concern Level |
|---|---|---|
| SaaS | 70-85% | Below 65% |
| E-commerce | 40-60% | Below 30% |
| Services | 50-70% | Below 40% |
| Marketplace | 60-80% | Below 50% |
Gross margin erosion is one of the earliest warning signs of trouble. It means either your pricing is wrong, your costs are rising, or your product mix is shifting toward lower-margin offerings. Run a quick check with a startup financial health checkup to see how your margin compares to peers.
6. Customer Acquisition Cost (Trailing 4-Week)
What it measures: How much you spent to acquire each new customer over the past month.
Formula: Total sales and marketing spend (last 4 weeks) / Number of new customers acquired (last 4 weeks)
Weekly check: Recalculate on a rolling 4-week basis. Compare to customer lifetime value to ensure the ratio stays healthy.
| LTV:CAC Ratio | Interpretation | Action |
|---|---|---|
| Over 5:1 | Under-investing in growth | Spend more on acquisition |
| 3:1 - 5:1 | Healthy and efficient | Maintain current approach |
| 1:1 - 3:1 | Marginal efficiency | Optimize channels |
| Under 1:1 | Losing money per customer | Stop spending, fix unit economics |
CAC tends to creep up as you exhaust your most efficient channels. Weekly tracking catches this drift early.
7. Operating Cash Flow Ratio
What it measures: Whether your operations generate enough cash to cover short-term obligations.
Formula: Cash from operations (trailing 4 weeks) / Current liabilities
Weekly check: Calculate using your most recent 4 weeks of operating cash flow divided by current liabilities (bills, payments, and obligations due within 30-60 days).
| Ratio | Status | Meaning |
|---|---|---|
| Over 1.0 | Strong | Operations fund obligations |
| 0.5 - 1.0 | Adequate | Some runway usage expected |
| Under 0.5 | Weak | Heavy reliance on reserves |
For pre-revenue or early-revenue startups, this ratio will be well below 1.0 -- that is expected. The key is tracking the trend. It should improve over time as revenue grows.
The 15-Minute Weekly Review Process
Block 15 minutes every Monday morning. Here is the exact process:
Minutes 1-3: Log your bank balance. Calculate weekly burn. Update your runway number.
Minutes 4-6: Pull weekly revenue. Compare to target and 4-week average. Note the trend direction.
Minutes 7-9: Check AR aging. Flag any accounts that moved into a worse bucket. Send collection reminders for 60+ day accounts.
Minutes 10-12: Review cash inflows vs. outflows. Calculate gross margin. Note any margin changes.
Minutes 13-15: Update CAC calculation. Check operating cash flow ratio. Record all seven KPIs in a simple tracker.
Use a single spreadsheet or dashboard. Do not over-engineer this. For a more comprehensive view, see our guide on building a financial dashboard for startups -- but the weekly review should stay fast and focused.
Setting Up Alerts
The weekly review catches most issues, but some problems cannot wait seven days. Set up automatic alerts for:
- Cash balance drops below 3 months of runway -- Immediate alert
- A single customer payment over $10K is 15+ days overdue -- Same-day alert
- Weekly revenue drops 25%+ from the 4-week average -- Next-day alert
- Any unexpected charge over $5K hits the bank account -- Same-day alert
These four alerts ensure nothing catastrophic slips through between weekly reviews.
Monthly Deep Dives
The weekly review is for quick pattern detection. Once a month, go deeper:
- Compare all seven KPIs to the same month last year
- Analyze customer-level profitability
- Review vendor contracts and pricing
- Update your financial forecast based on actual trends
- Review budget vs. actual for all major categories
FAQ
Which KPI is most important for pre-revenue startups?
Cash balance and burn trajectory. When you have no revenue, everything depends on how long your money lasts. Track your bank balance religiously and calculate runway weekly. All other KPIs become relevant once you have customers and revenue.
How do I handle weeks with unusual spikes (like a quarterly tax payment)?
Exclude known one-time or quarterly items from your weekly burn calculation but track them separately. Create a "normalized" view for trend analysis and a "cash-basis" view for actual runway calculation. Both are important.
Should I share weekly KPIs with my team?
Yes, but selectively. Share revenue and growth metrics with the whole team to create alignment. Share cash and runway numbers with your leadership team and board. Transparency about financial health builds trust and helps the team make better decisions.
