Exercising now and holding for long-term gains costs about $96,800 in tax, versus $140,600 waiting until exit and paying ordinary rates.

The signed wait-minus-exercise-now tax difference is $43,800; positive favors exercising now in this narrow model and negative favors waiting. Exercising now still means real cash out of pocket and AMT risk if the company never has a liquidity event.

Frequently Asked Questions

Everything you need to know.

What does an example Pre-IPO Equity Outcome Calculator calculation look like?
Using this calculator's own default assumptions, a number of shares of 10000, strike price of $2 and current fair market value of $10 produces an estimated tax if you wait until exit of $140,600 and cost to exercise now of $20,000. Enter your own numbers above to see how it changes for your situation.
What is AMT and why does early exercise trigger it?
AMT is an alternative calculation of tax that can apply when you exercise incentive stock options. The spread between your strike price and current fair market value on exercise is treated as a preference item; if this pushes your total income above a threshold, you owe AMT in addition to regular income tax. AMT can exceed regular tax if the spread is large, making early exercise costly. The calculator compares this AMT hit against the benefit of locking in a lower starting basis for future gains.
Why would I exercise now if waiting seems cheaper?
If you exercise now and hold the shares for over one year, future gains are taxed at long-term capital gains rates, which are typically lower than ordinary income rates. If you wait to exercise until closer to exit, any gain from strike to exit price is taxed at ordinary rates, which can be higher. The calculator shows which timing results in lower total tax after accounting for both the immediate exercise cost and the tax on your eventual gain. Early exercise also gives you more time to let the shares appreciate tax-deferred.
Is the Pre-IPO Equity Outcome Calculator free to use?
Yes. SwitchWize calculators are free, and you do not need an account to run scenarios or view the result.
Does using the Pre-IPO Equity Outcome Calculator affect my credit score?
No. Using a calculator does not trigger a credit check. A credit impact can occur only if you apply directly with a lender, card issuer, or provider.
Are the results personalized financial advice?
No. Calculator outputs are educational estimates based on the inputs you enter. Review assumptions and confirm terms directly with providers before making a financial decision.
What should I do after seeing the result?
Use the recommendation module on this page to compare brokerage accounts, or run Money Map to compare this investing & retirement decision with your other opportunities.
How does SwitchWize choose related offers?
Related offers are matched by the calculator surface (brokerage) and ranked using SwitchWize data such as rate, fees, trust signals, product fit, and switching friction. Paid relationships do not change organic ranking order.
How fresh are the rates and offers shown?
Rate and offer data is reviewed on a recurring cadence and every offer module shows review context or links to the methodology and disclosure pages.
Where can I see the ranking methodology?
The SwitchWize methodology page explains how rate freshness, editorial review, affiliate disclosure, and category ranking factors work.
Can Money Map use this result?
Yes. Money Map is the broader diagnostic path: it compares savings, mortgage, cards, and debt so you can see whether this calculator result is your highest-impact next move.

Why This Matters

Exercising early locks in a lower tax basis but triggers immediate out-of-pocket costs and potential AMT liability. Waiting defers costs but risks a larger spread between strike and exit price, which becomes taxable income at ordinary rates or long-term capital gains rates depending on timing. This calculator isolates the tax math to show which scenario leaves you with more after-tax proceeds.

How to Use It

  1. 1Enter the total number of shares in your equity grant.
  2. 2Enter your strike price per share (the price you'd pay to exercise).
  3. 3Enter the current fair market value per share (for AMT purposes and current intrinsic value).
  4. 4Enter your expected exit price per share (your modeled sale price at IPO, acquisition, or liquidity event).
  5. 5Enter your estimated alternative minimum tax rate if exercising triggers AMT.
  6. 6Enter your long-term capital gains tax rate (the rate applied to gains held over one year).
  7. 7Enter your ordinary income tax rate (the rate applied to wages and short-term gains).
  8. 8Review your cost to exercise now, estimated AMT exposure, total tax under each scenario, and the modeled difference to compare outcomes.
