Compensation planning · Equity awards
You know the headline value. This page estimates what the model keeps.
A single grant of RSUs, nonqualified options, or incentive options. Pretax value, a federal-tax estimate, and the size of the position next to an investable-asset figure you enter. The numbers update as you type. Nothing is sent unless you use the optional form at the bottom.
Illustrative calculations only. State tax is not included. Withholding can differ from the rate entered here. The rate is an assumption, not a determination of tax.

Assumptions
Prefilled with an example so a result is on the page immediately. Replace any figure with the grant you want to illustrate.
A label in the summary. This page does not look up a market price.
Label only.
Every dollar figure uses this price. The older hosted page could fetch a Yahoo Finance quote and used $150 when that failed. This page starts at $150. Type the price you want to illustrate.
Used for every figure. No live quote is fetched.
Whole grant. At least 100 shares.
The price paid to exercise an option. The bargain element is the market price minus the strike, and it is never below zero. RSUs do not use the strike. It stays on the page so switching the award type does not lose it.
Not used for RSUs. Options use price minus strike.
One flat rate applied wherever this model uses federal tax. The original tool offered 22% through 37% only. It is not a bracket calculation, and it is not withholding.
Flat rate from 22% to 37%. State tax is not applied.
Used only for ISOs, and only on the bargain element of the next vesting tranche. The original tool offered 0% through 28%. The growth chart does not use this rate.
ISO tranche only. 0% to 28%.
The countdown uses the date on this computer as “today.” The model converts the gap into months by dividing days by 30 and dropping the remainder. It does not count calendar months. The default is the later of June 1, 2026 and today.
Countdown from today. A model month is 30 days.
This tranche only. Zero is allowed.
The denominator for the concentration percentages. A rough figure is enough. This model’s floor is $100,000, the same floor as the original tool. The position value in the numerator is described under the result.
Rough figure. Minimum in this model is $100,000.

Questions this illustration leaves open
Show the math for these inputs
Assumptions in this model
- One flat federal rate. No state tax, net investment income tax, or payroll tax.
- A month is 30 days, not a calendar month. The month count is never negative.
- The growth charts move today’s price by a percentage and apply the same net formula. They do not include dividends, and the result is not discounted.
- RSUs: the net figure is price × shares × (1 − federal rate). Tax on the next vest is price × vesting shares × federal rate.
- NSOs: tax on the next vest is that tranche’s bargain element × federal rate. The headline net is the full grant’s bargain element × (1 − federal rate), plus strike × all shares.
- ISOs: tax on the next vest is that tranche’s bargain element × the AMT rate. The headline net is that tranche’s bargain element minus the AMT estimate, plus strike × all shares. The growth chart uses the NSO formula instead, at the federal rate.
- Concentration for RSUs uses price × shares. For options it uses the bargain element plus strike × shares.
- The post-vesting percentage adds the next tranche’s pretax value on top of that position value.
- The sell and hold lines use those original formulas. Neither line is a suggestion to sell or to hold.
