Venture Loss Ratios: Count Losses and Dollars Separately
Calculate count-based and dollar-based venture loss measures from one realized ledger, with explicit numerators and denominators.
What you will learn
- Distinguish several clearly labeled loss measures.
- Calculate each from a fully realized fictional portfolio.
- Avoid mixing unrealized marks with final cash outcomes.
A count-based loss ratio and a dollar-weighted loss measure can tell different stories. Define whether you mean investments below cost, capital invested in those deals, actual capital shortfall or complete write-offs. Publish the numerator and denominator, not an unexplained “loss rate.”
Choose the question before the label
For this lesson, “below cost” means realized proceeds less than invested capital for a completed investment. “Write-off” means zero proceeds under the example. The measures below are explicitly chosen analytical definitions, not a claim that one universal industry loss-ratio convention exists.
Invest Europe’s investment reporting guidance separates investment-level cost, valuation and realized gain/loss information. Keep those underlying fields available so a reader can reproduce whichever loss definition you use.
Start from the investment ledger
All four fictional investments are fully realized. No fund fees, carry, follow-ons, foreign exchange or residual value apply. Amounts are millions of US dollars.
Original realized-outcome ledger, $M
| Investment | Cost | Proceeds | Proceeds minus cost | Below cost? |
|---|---|---|---|---|
| A | $1 | $0 | −$1 | Yes, complete loss |
| B | $2 | $1 | −$1 | Yes, partial loss |
| C | $3 | $3 | $0 | No |
| D | $4 | $12 | +$8 | No |
| Total | $10 | $16 | +$6 | 2 of 4 investments |
Calculate four different measures
Loss measures with explicit denominators
| Measure | Calculation | Result |
|---|---|---|
| Below-cost share by count | 2 losing investments ÷ 4 completed investments | 50% |
| Cost allocated to below-cost investments | ($1M + $2M) ÷ $10M invested | 30% |
| Realized capital shortfall on losing investments | ($1M + $1M) ÷ $10M invested | 20% |
| Complete-loss share by count | 1 zero-proceeds investment ÷ 4 | 25% |
The first measure says how many investments lost money. The second says how much capital was placed in those investments. The third measures the capital shortfall in the losing subset. They are not interchangeable. Full-loss cost is separately $1M ÷ $10M = 10%.
Keep winning outcomes in the complete explanation
The portfolio still realizes $16 million on $10 million invested, a 1.60x gross multiple before fund costs. A positive portfolio result does not erase A and B’s losses. A 50% below-cost count also does not mean half of all invested dollars were lost.
Do not net D’s gain against losing deals and label the result a loss ratio. Show the entire portfolio result and the chosen loss measure side by side. For an ongoing portfolio, label marked-below-cost investments separately from completed realized losses.

Make the metric useful in diligence
Ask what a reported loss rate counts, which investments it excludes and how much capital those investments represent. Save the response with the relevant LP materials through Finta’s LP follow-up workflow. A loss measure supports understanding; it does not establish future performance or suitability.
