Exit Proceeds Calculator
Net startup exit proceeds.
Calculate net exit proceeds from ownership percentage, valuation, liquidation preferences ahead of you, and applicable tax.
What this tool does
This calculator models the net cash proceeds you receive from a startup exit by accounting for ownership stake, sale valuation, and prior claims on the proceeds. The result represents your take-home amount after liquidation preferences—claims that preferred shareholders receive before common shareholders—and applicable taxes are deducted. Exit valuation and your ownership percentage are the primary drivers of the outcome, while liquidation preferences and tax rate reduce the final figure. A typical scenario involves a founder or early investor estimating personal proceeds from an acquisition or funding round. The calculation assumes a straightforward waterfall structure and does not model dilution from future funding rounds, carry arrangements, earnouts, transaction fees, or jurisdiction-specific tax treatments. Results are for educational illustration only.

Exit proceeds depend on ownership %, exit valuation, liquidation preferences (paid first to investors), and tax. After preferred shareholders take their preferences, remaining 'distributable' pool divided by ownership %. Common shareholders (founders, employees) often receive less than naive math suggests due to liquidation preferences.
10% ownership × 100M exit = 10M naive. But 20M liquidation preferences for investors = 80M distributable. 10% × 80M = 8M gross. After 25% tax: 6M net. The 20M preference reduces your proceeds 20% before tax. Understanding waterfall critical for founders/employees.
Liquidation preference structures: 1x preference (investor gets back original investment first, then participates pro-rata) - most common. 2x preference (gets back 2x investment first) - aggressive, harms founders. Participating vs non-participating: participating means investor gets preference AND pro-rata share. Each variation can change founder proceeds 30-60% on smaller exits.
Run it with sensible defaults
Using ownership of 10%, exit valuation of 100,000,000, liquidation preferences of 20,000,000, tax rate of 25%, the calculation works out to 6,000,000.00. The defaults are meant as a starting point, not a recommendation.
The levers in this calculation
The inputs — Ownership %, Exit Valuation, Liquidation Preferences, and Tax Rate % — do not pull with equal force. Not every input has equal weight. Adjusting one input at a time toward extreme values shows which ones move the result most.
How the math works
Distributable = exit - preferences. Gross = ownership × distributable. Net = gross × (1 - tax).
Why run this
Running the numbers makes the trade-offs concrete. Small changes in the inputs can move the result more than intuition suggests, which is hard to judge without working it out.
What this doesn't capture
This is a simplified model that holds its assumptions constant. Real outcomes vary with market conditions, costs, taxes, and timing, so the figure is best read as one scenario rather than a forecast.
10% × (£100,000,000 - £20,000,000) × (1 - 25%) = $6,000,000.00.
Inputs
This example uses typical values for illustration. Adjust the inputs above to match a specific situation and see how the result changes.
Sources & Methodology
Methodology
This calculator models the net proceeds from a startup exit by applying ownership stake, liquidation preferences, and tax treatment in sequence. It first subtracts total liquidation preferences from the exit valuation to determine distributable proceeds. It then applies your ownership percentage to this distributable amount to calculate your gross share. Finally, it applies the tax rate as a multiplier to derive net proceeds after taxes. The model assumes a flat tax rate applied uniformly to proceeds, treats liquidation preferences as a fixed first-claim deduction, and does not model variable tax brackets, transaction fees, advisory costs, or the mechanics of preference waterfalls across multiple investor classes. Results reflect a simplified single-investor scenario.
