Financial Metrics VCs Check First in Due Diligence
VCs reject 74% of deals during financial due diligence. Know the 12 metrics they check first, with passing thresholds and red flags by funding stage.
74% of venture capital deals that reach the due diligence phase are rejected, and financial concerns are the leading reason. VCs have a systematic process for evaluating financial health, and they check the same metrics in the same order, every time. If you know what they are looking for and prepare accordingly, you dramatically improve your odds of passing.
Due diligence is not a mystery. It is a structured evaluation with predictable criteria. This guide reveals the exact metrics VCs check, in the order they check them, with the passing thresholds at each funding stage. Think of it as the answer key to the test you are about to take.
The 12 Metrics VCs Check (In Order)
Tier 1: Go/No-Go Metrics (Checked First)
These four metrics determine whether the VC continues the process or kills the deal immediately.
1. Revenue Growth Rate
| Stage | Minimum to Pass | Target | Top Decile |
|---|---|---|---|
| Pre-seed | N/A | Evidence of demand | N/A |
| Seed | 10%+ MoM | 15-20% MoM | 25%+ MoM |
| Series A | 8-10% MoM | 12-15% MoM | 20%+ MoM |
| Series B | 5-8% MoM | 8-12% MoM | 15%+ MoM |
| Series C | 30%+ YoY | 50%+ YoY | 80%+ YoY |
What they are really asking: "Is this company growing fast enough to justify venture-scale returns?"
A seed-stage company growing at 5% MoM will not reach venture-relevant scale in a reasonable timeframe. At 5% MoM, $10K MRR takes 4 years to reach $1M ARR. At 15% MoM, it takes 18 months.
2. Net Burn Rate and Runway
| Stage | Minimum Runway | Preferred Runway | Red Flag |
|---|---|---|---|
| Pre-seed | 12 months | 18+ months | Under 9 months |
| Seed | 15 months | 18-24 months | Under 12 months |
| Series A | 18 months | 24+ months | Under 15 months |
| Series B | 18 months | 24-30 months | Under 15 months |
What they are really asking: "How much time pressure is on this deal?" Companies with less than 12 months of runway are in a weak negotiating position, and VCs know it.
3. Gross Margin
| Business Type | Minimum to Pass | Target | Red Flag |
|---|---|---|---|
| SaaS | 65% | 75-85% | Below 60% |
| Marketplace | 50% | 60-75% | Below 45% |
| E-commerce (own brand) | 35% | 45-60% | Below 30% |
| Hardware + software | 30% | 40-55% | Below 25% |
What they are really asking: "Does each dollar of revenue leave enough margin to fund growth?" Low gross margins mean the company must spend more revenue on delivery, leaving less for sales, marketing, and R&D.
4. Revenue Quality (NRR)
| Stage | Minimum to Pass | Target | Top Decile |
|---|---|---|---|
| Seed | 80%+ | 90-100% | 100%+ |
| Series A | 90%+ | 100-110% | 115%+ |
| Series B | 100%+ | 110-120% | 125%+ |
| Series C+ | 105%+ | 115-130% | 140%+ |
What they are really asking: "Does this company have real product-market fit, or is it acquiring customers into a leaky bucket?"
Run a startup financial health checkup to see how you score across all four go/no-go metrics before entering due diligence.
Tier 2: Efficiency Metrics (Checked Second)
If Tier 1 passes, VCs dig into how efficiently you are growing.
5. CAC Payback Period
| Stage | Acceptable | Target | Excellent |
|---|---|---|---|
| Seed | Under 18 months | Under 12 months | Under 6 months |
| Series A | Under 15 months | Under 10 months | Under 6 months |
| Series B+ | Under 12 months | Under 8 months | Under 5 months |
6. LTV:CAC Ratio
| Stage | Minimum | Target | Excellent |
|---|---|---|---|
| Seed | 2:1 | 3:1 | 5:1+ |
| Series A | 3:1 | 4:1 | 6:1+ |
| Series B+ | 3:1 | 5:1 | 7:1+ |
Warning: An LTV:CAC above 8:1 is not always good -- it can signal under-investment in growth.
7. Burn Multiple
The burn multiple (net burn / net new ARR) is increasingly the primary efficiency metric VCs use:
| Burn Multiple | Rating | Interpretation |
|---|---|---|
| Under 1x | Excellent | Highly efficient growth |
| 1x-1.5x | Good | Sustainable |
| 1.5x-2x | Concerning | Inefficient but salvageable |
| 2x-3x | Poor | Likely not venture-fundable |
| Over 3x | Dangerous | Burning cash without productive growth |
8. Rule of 40
Revenue growth rate + profit margin >= 40%
| Score | Rating | Example |
|---|---|---|
| 60+ | Exceptional | 80% growth + (-20%) margin |
| 40-60 | Strong | 50% growth + (-10%) margin |
| 20-40 | Acceptable (early stage) | 40% growth + (-20%) margin |
| Under 20 | Concerning | 20% growth + (-10%) margin |
Tier 3: Structural Metrics (Checked Last)
These metrics reveal potential issues in the business structure.
9. Revenue Concentration
| Metric | Safe | Warning | Red Flag |
|---|---|---|---|
| Top customer % of revenue | Under 10% | 10-20% | Over 25% |
| Top 5 customers % of revenue | Under 25% | 25-40% | Over 50% |
| Single industry % of revenue | Under 40% | 40-60% | Over 70% |
10. Expense Structure
| Expense Category | Healthy Range | Red Flag |
|---|---|---|
| R&D as % of revenue | 20-40% | Over 50% (at Series A+) |
| S&M as % of revenue | 30-50% | Over 70% |
| G&A as % of revenue | 10-20% | Over 25% |
| Hosting as % of revenue | 5-15% | Over 25% |
11. Working Capital and Cash Conversion
VCs check the gap between when you spend money and when you collect it:
- Accounts receivable days: Under 45 is healthy; over 60 is concerning
- Payment terms trend: Getting longer = customer leverage increasing
- Deferred revenue: Large balance = strong indicator of future revenue
12. Financial Controls and Reporting Quality
| Factor | Pass | Fail |
|---|---|---|
| Monthly close within 10 business days | Yes | No |
| Reconciled bank statements | Yes | No |
| Budget vs. actual tracking | Yes | No |
| Clean cap table | Yes | No |
| GAAP-compliant financials | Yes (Series A+) | Not required for seed |

The Narrative for Below-Threshold Metrics
Every company has weak spots. What matters is whether you can explain them:
Good explanation: "Our CAC payback is 14 months because we invested heavily in enterprise sales this quarter. The three enterprise deals closing next month will bring payback to 9 months."
Bad explanation: "We are still figuring out our go-to-market." This signals a fundamental, unsolved problem.

FAQ
How long does financial due diligence take?
Typically 2-4 weeks for seed/Series A and 4-8 weeks for Series B+. The timeline depends on how prepared your data is. Companies with clean financials and organized data rooms close due diligence 40% faster.
Can I negotiate while in due diligence?
Due diligence is not the time to negotiate terms -- that should be settled in the term sheet before due diligence begins. However, findings in due diligence can and do cause term sheet adjustments. Clean financials protect against negative re-negotiation.
What metric weaknesses are most likely to kill a deal?
Declining revenue growth, runway under 9 months, and customer concentration above 25% are the top three deal-killers. These signal fundamental risk. Other metric weaknesses can be explained with narrative and improvement plans.
