What this calculator does not model
- ISOs / NSOs — stock options have a strike price, AMT exposure, and exercise timing. Different math entirely.
- Pre-IPO illiquidity — private company RSUs may have no public market to sell into.
- Share price volatility — we model a flat growth rate. Real grants can swing 30-50% in either direction.
- Section 83(b) elections — early-exercise private options can shift the tax clock.
Disclaimer
Tax estimates use simplified 2024-2025 brackets. They exclude FICA on RSU income above the wage base, AMT, NIIT (3.8%), state-specific credits, and spouse income. Treat the take-home figure as a planning estimate, not a tax return. For a meaningful RSU grant, talk to a CPA familiar with equity compensation.
Frequently asked questions
How do I use RSU / Equity Value Calculator step by step without mistakes?
Follow the order given in the usage section: Vesting schedule + NY state + federal tax drag, modeled per tranche. The step-by-step part matters less than the unit check that sits inside it. Confirm every unit matches the thing you are actually trying to measure before you press calculate - that single check catches more wrong answers than any other habit, and it costs about ten seconds.
What are the common mistakes when using RSU / Equity Value Calculator?
Most common mistakes come down to four habits: entering 20 when the field expects 0.2 because the field is a percentage; leaving a field blank and accepting the default without checking what it stands for; changing one input and reading a result that was calculated before the change; and quoting the output as an exact figure when the page describes it as a reference estimate. Press calculate again after any edit, and treat the number as a reference point rather than a final answer.
How do I read the result from RSU / Equity Value Calculator?
Read the final figure first, then come back to this section for the conditions behind it: Vesting schedule + NY state + federal tax drag, modeled per tranche. Keep two things apart: the number itself, which comes from the values you typed, and the assumptions it depends on, which decide whether that number is meaningful. The page sets out what a higher or lower result means for your case, so check that direction as well as the magnitude.
Can I act on the RSU / Equity Value Calculator result directly?
Treat it as one reference sheet before you decide, rather than as the answer itself: Vesting schedule + NY state + federal tax drag, modeled per tranche. The output describes a magnitude under the conditions you entered. It does not include what it actually costs to act, what might change while you act, or how the other side behaves. Before you commit, compare the result against reality and note which assumptions do not hold where you are.
What inputs does RSU / Equity Value Calculator need?
RSU / Equity Value Calculator takes 4 inputs: Total grant value at vest (today)、Vesting schedule、Annual share price growth assumption、Filing status. They are listed in the order they feed the calculation, so an earlier value can change a later one. Do not skip a field you do not recognise - work out what it means first, because a silently guessed value produces a number that looks reasonable and is not. Before typing anything, make sure every figure uses the same unit and the same time period.
What should I check before I run RSU / Equity Value Calculator?
Three checks pay for themselves. First, confirm the question you need answered is really inside the scope of this tool rather than a neighbouring one. Second, confirm that the figures you have are drawn from the same source and the same period - mixing monthly and annual numbers, or two different definitions of the same quantity, quietly distorts the result. Third, keep the key inputs written down, so that later you can tell which set of numbers produced a figure you are about to quote.
Who is RSU / Equity Value Calculator for, and who should not use it?
It suits people who already have concrete numbers and want a quick sense of scale - drafting a budget, aligning on a figure with a colleague, or sanity-checking an estimate before a meeting. It is not for people who need an exact value they can promise to a third party, and it is not for people who have not yet agreed what each input means. Spending a few minutes settling the definitions first is far cheaper than re-running the numbers afterwards.
