This Series A Valuation Estimator produces an indicative pre-money valuation from annual recurring revenue and a selected revenue multiple, then checks the implied investor ownership for a proposed raise. It is useful for scenario planning before term-sheet negotiations.
The model is intentionally simple. Multiples vary with growth, retention, gross margin, market conditions, and deal terms, so the output is not an appraisal. Use a range of assumptions rather than relying on one point estimate.
1. Enter ARR
Use current or forward annual recurring revenue, but label the basis consistently.
2. Choose a multiple
Enter a scenario multiple appropriate to the company’s quality and market context.
3. Enter the raise
Add the proposed Series A investment amount.
4. Adjust for debt
Optionally subtract debt to move from enterprise value toward equity value.
5. Compare scenarios
Change the multiple and raise size to see valuation and ownership sensitivity.
The estimator assumes a recurring-revenue multiple is appropriate and does not add excess cash or model preferred terms. Multiples are market-dependent inputs, not fixed rules.
The main result is an indicative pre-money equity value under the selected ARR multiple.
Use comparable-company, precedent-transaction, and discounted-cash-flow work for a broader valuation analysis.
Given
Calculation
Enterprise value = $4,000,000 × 6.0 = $24,000,000. Post-money = $24,000,000 + $8,000,000 = $32,000,000. Investor ownership = 25%.
Result
Indicative pre-money valuation = $24,000,000.
At these assumptions, an $8 million investment implies a 25% post-money stake.
Use the basis that matches the selected multiple and clearly label it. Mixing a forward multiple with current ARR can distort the estimate.
Consider growth, retention, gross margin, market size, concentration, and current financing conditions. Test a range rather than one number.
A revenue multiple generally estimates enterprise value. Debt is one adjustment used to estimate equity value.
No. You may add excess cash separately when appropriate, but transaction definitions vary.
No. It is a scenario estimate based on one multiple and does not replace professional valuation or negotiated deal terms.
