The VC Method, Work Backward From Exit
Works backward from a projected exit to post-money and pre-money valuations and the ownership a venture investor needs today, including an adjustment for expected future dilution. Inputs are the exit value, target annual return, years to exit, the investment amount, and expected dilution.

How does the venture capital method estimate today’s valuation?
Start with a projected exit equity value and the investor’s target return. Work backward to the required ownership at exit, then allow for future dilution to find the stake needed today. Investment divided by that current stake gives the implied post-money value.

Start with exit equity value and the investor’s target return. Divide the required exit stake by the retention ratio to find the stake needed today. Today’s post-money value is investment divided by that stake; pre-money is post-money less the new investment. Without future dilution, the implied post-money value would be $50.0M. This is a scenario, not a promised return.
Understand the numbers
A worked example, step by step
Enter a $50 million exit equity value, 25% target annual return, five years to exit, a $2 million investment, and 20% expected future dilution.
This fixed teaching example is separate from your saved calculator inputs. Enter the assumptions above to reproduce it.
- Target multiple = 1.25⁵ = 3.0518×. The investor targets about $6.104 million at exit.
- Required exit ownership = $6.104 million ÷ $50 million = 12.207%. Required ownership today = 12.207% ÷ 80% = 15.259%.
- Dilution-adjusted post-money value = $2 million ÷ 15.259% ≈ $13.107 million. Pre-money value ≈ $11.107 million.
15.26% needed today · about $13.11M post-money
What the result tells you
Without future dilution, the implied post-money value would be $16.384 million. Allowing for 20% dilution lowers the price the investor could pay today while preserving the same target exit proceeds.
Assumptions to check
Use exit equity value after debt and senior claims, not enterprise value without adjustment. A target return is an assumption, not a promise or a probability-weighted forecast. This simplified method omits liquidation preferences, follow-on investment, and a full distribution of possible exits. Required ownership above 100% means the assumptions cannot support the deal.
Try one change
Set future dilution to zero, then restore 20%. The required exit stake should stay the same; today’s stake and implied valuation should change.
