Track vesting, withholding, sale timing, and proceeds. Compare federal, state, payroll, and gains tax effects. Understand equity outcomes before making compensation decisions with confidence.
Use custom share counts, prices, tax rates, and dates. The form keeps a single stacked page layout, while fields adapt to screen size.
| Example item | Value | Notes |
|---|---|---|
| Shares granted | 1,000 | Total award shares at grant. |
| Shares vested | 500 | Portion becoming taxable at vest. |
| Grant FMV | $8.00 | Used when estimating 83(b) treatment. |
| Vest FMV | $20.00 | Default income value per vested share. |
| Sale price | $26.00 | Price received on sold shares. |
| Ordinary tax rates | 34.65% | Federal, state, Social Security, and Medicare combined. |
| Estimated ordinary income | $10,000.00 | 500 × $20.00 without 83(b). |
| Estimated total tax | $3,915.00 | Includes ordinary tax and long-term gains tax. |
| Estimated net proceeds | $9,060.00 | $13,000 sale value minus tax and fees. |
Ordinary Income = Shares Vested × Taxable Value Per Share
Taxable value per share equals vest-date FMV in the standard case. If an 83(b) election is applied, the grant-date FMV is used instead.
Ordinary Tax = Ordinary Income × (Federal + State + Local + Social Security + Medicare)
This calculator combines user-entered payroll and income tax rates into one estimated withholding-style burden.
Capital Gain = Shares Sold × (Sale Price − Basis Per Share)
Basis per share equals the taxable value per share already recognized as compensation income.
Capital Gains Tax = Positive Capital Gain × (Short-Term or Long-Term Rate + NIIT)
The calculator treats gains as long-term when the holding period exceeds 365 days from the relevant start date.
Net Proceeds = Gross Sale Value − Broker Fees − Ordinary Tax − Capital Gains Tax
This gives a practical estimate of what remains after modeled taxes and transaction costs.
Input shares granted, vested, and sold. Then enter grant-date FMV, vest-date FMV, and the actual sale price per share.
Enter grant, vesting, and sale dates. These dates determine the holding period and whether gains are treated as short-term or long-term.
Provide federal, state, local, payroll, and capital gains tax rates. Add NIIT and broker fees for a more complete estimate.
Check the 83(b) box only when you want to model ordinary income from grant-date FMV and an earlier holding-period start.
Submit the form to show results above the calculator. Use the built-in CSV and PDF buttons to save the breakdown.
It estimates ordinary income, withholding-style tax, capital gain or loss, total tax, and net proceeds from vested restricted stock that may later be sold.
It is designed for restricted stock style modeling. It can still help with RSU-style estimates, but the award mechanics and employer withholding rules may differ.
Without an 83(b) election, vest-date fair market value usually determines the compensation income recognized when the shares vest.
The model taxes the shares using grant-date FMV and starts the holding period at grant. That can reduce ordinary income if grant value was lower.
The calculator counts days from vest date by default. When 83(b) is checked, it counts from grant date instead.
Ordinary tax may apply to all vested shares, not just sold shares. Capital gains tax and broker fees can reduce proceeds even further.
No. You enter the effective rates you want to model. That makes the calculator flexible for planning different tax scenarios.
No. It is a planning estimate. Actual tax treatment can change with payroll limits, brackets, deductions, and jurisdiction-specific rules.
