Formula and Logic
This calculator uses standard equity compensation valuation methods:
- Current Grant Value = Number of Shares × Current Stock Price
- Projected Vested Value accounts for compounded annual growth and vesting schedule timing.
- For RSUs: Tax liability is calculated as Projected Vested Value × Ordinary Income Tax Rate.
- For NSOs: Tax applies to the spread between vested value and strike price paid, split between ordinary income and capital gains where applicable.
- Net Value = Projected Vested Value - Cost to Acquire Shares - Total Estimated Tax.
Practical Notes
Keep these finance-specific tips in mind when using this tool:
- Stock price growth rates are estimates only; past performance does not guarantee future results.
- RSUs are taxed as ordinary income when shares vest, so factor this into your annual tax planning.
- ISOs may trigger Alternative Minimum Tax (AMT) even if you do not sell the shares immediately.
- Vesting schedules vary by employer; always confirm your grant's specific terms with your HR or financial advisor.
- Tax rates used should reflect your marginal ordinary income and long-term capital gains rates for accuracy.

Frequently Asked Questions
Are stock grants taxed when they are granted or when they vest?
RSUs are taxed as ordinary income when the shares vest and are delivered to you. Stock options (ISO/NSO) are not taxed when granted; taxation occurs when you exercise the options, with additional taxes applied when you sell the acquired shares.
What is the difference between RSUs and stock options?
RSUs are company shares granted to you for free once vesting conditions are met. Stock options give you the right to purchase company shares at a set strike price, which only has value if the current stock price is higher than the strike price.
Can I change my vesting schedule after accepting a grant?
Vesting schedules are set by your employer in the grant agreement and are rarely changeable after acceptance. Always review vesting terms carefully before accepting an equity compensation offer.
