Net outcome sensitivity graph

The graph shows how your estimated net outcome changes as share price changes. For cashless sale, the price varies at same-day sale. For hold strategies, the price varies at future exit.

Formula Used

Core calculation logic

Vested Options = Total Grant × (Vested Percentage ÷ 100)

Intrinsic Value per Share = max(Current Fair Market Value − Strike Price, 0)

Bargain Element = Vested Options × Intrinsic Value per Share

Exercise Cost = (Vested Options × Strike Price) + Exercise Fee + Broker Fee + Other Fees

Estimated Tax at Exercise = Ordinary Income × Ordinary Tax Rate + Payroll Tax, when applicable

Cash Needed = Exercise Cost + Estimated Tax at Exercise

Capital Gain Base = max(Future Sale Price − Current Fair Market Value, 0) × Shares Retained

Projected Net Outcome = Gross Sale Value − Capital Gains Tax − External Cash Needed + Residual Cover Cash

FAQs

Common questions

1) What does exercise value mean in employee benefits?

It is the estimated value created when you buy vested option shares at the strike price and compare that cost with market value, taxes, fees, and future sale assumptions.

2) Why does the calculator ask for vested percentage?

You usually can exercise only vested options. The calculator converts your total grant into exercisable shares so the cost, taxes, and retained-share estimates reflect what is currently available.

3) What is the difference between cash exercise and sell to cover?

Cash exercise assumes you fund the purchase and taxes externally. Sell to cover assumes some shares are sold immediately to pay the required cash, leaving fewer shares to hold.

4) When is cashless same-day sale useful?

It can help when you want liquidity and do not want to provide personal cash. The tradeoff is that you usually keep no shares for future upside.

5) Does this calculator handle ISO and NSO taxes perfectly?

No. It gives a practical estimate for planning. ISO treatment can involve holding-period rules and AMT effects, so final tax results may differ from the simplified output shown here.

6) What does break-even share price tell me?

It shows the approximate share price needed for your selected strategy to stop producing a loss after exercise cost, taxes, and fees are considered.

7) Why can a higher future sale price still produce limited value?

Taxes, fees, and share sales used for funding can reduce upside. If many shares are sold to cover, fewer retained shares remain to benefit from future appreciation.

8) Should I rely only on this result before exercising?

No. Use it for planning, then confirm grant terms, blackout windows, expiration dates, withholding rules, and personal tax consequences with your equity plan team or advisor.
