Restricted Stock Unit Calculator

Restricted Stock Units (RSUs) are a form of equity compensation granted by employers to employees as part of a total compensation package. Unlike traditional stock options, RSUs represent a promise to deliver actual company shares — or their cash equivalent — once a specific vesting schedule is satisfied. They are called "restricted" because employees cannot sell or transfer them until those conditions are met.

RSUs have become one of the most popular forms of equity compensation, particularly in the technology and finance sectors. Companies use them to attract and retain top talent by aligning employee incentives with long-term company performance. When your RSUs vest, you receive shares outright, making them simpler to understand than stock options since there is no strike price to pay.

Understanding the full value of your RSU grant requires tracking several moving pieces: the total number of shares granted, the current market price, how much has already vested, and the tax burden you'll face when shares vest and again when you sell. This RSU calculator handles all of those calculations in one place, giving you a complete picture of your equity compensation's current worth and projected future value.

RSUs can vest based on time (cliff or graded schedules), performance milestones, or a combination of both. A four-year graded vest with a one-year cliff is one of the most common structures — you receive nothing in year one, then 25% of your grant at the end of year one, followed by monthly or quarterly installments for the remaining three years. Knowing your schedule is essential for accurate planning.

This restricted stock unit calculator uses seven inputs to produce ten distinct outputs that capture every financially relevant dimension of your RSU grant. All formulas mirror the exact JavaScript logic used in the calculator engine.

The core outputs start with vested shares, derived by multiplying your total shares by the vested percentage you enter. From there, the calculator computes current dollar values, tax obligations on vested shares, total appreciation since grant, and a forward-looking projected value based on an expected annual growth rate and time remaining to full vest.

The future price projection uses compound growth: each year's price is multiplied by one plus the growth rate, raised to the power of the remaining years to full vest. This matches standard compound interest logic and gives you a realistic baseline scenario for your unvested shares.

Your vesting schedule determines when you legally own each tranche of shares in your RSU grant. The two most common structures are cliff vesting and graded vesting. With cliff vesting, none of your shares vest until a single date — typically one year after grant. Graded vesting releases shares incrementally, often quarterly or monthly over three to four years after an initial cliff period.

The vested percentage field in this calculator represents the cumulative fraction of your grant that has already vested as of today. For example, if you are 18 months into a standard four-year grant with a one-year cliff, you would have received 25% at month 12 plus six additional monthly increments of approximately 2.08% each, totaling roughly 37.5% vested. Enter that percentage and the calculator instantly shows your current vested value and remaining unvested exposure.

Performance-based vesting adds another dimension. Some RSU grants include multipliers that increase or decrease the number of shares delivered based on company or individual metrics. This calculator uses a fixed vested percentage, which is accurate for time-based grants. For performance RSUs, use your best estimate of the expected payout percentage in the vested field.

Termination events typically forfeit all unvested RSUs immediately. Change-of-control provisions, sometimes called "double trigger" clauses, may accelerate vesting if you are terminated within a certain period following an acquisition. Always read your grant agreement carefully to understand what happens to unvested shares if your employment ends before full vesting.

RSUs create two separate taxable events that you must plan for carefully. The first occurs at vesting: the fair market value of shares on the vest date is treated as ordinary income, subject to federal income tax, Social Security, Medicare, and any applicable state income tax. Most employers withhold a flat 22% federal rate for supplemental wages at vesting — but if your marginal rate is higher, you may owe additional tax when you file.

The second taxable event occurs when you sell the shares. The difference between your sale price and the fair market value on the vest date is treated as a capital gain or loss. If you hold the shares for more than one year after vesting, you qualify for long-term capital gains rates, which are lower than ordinary income rates for most taxpayers.

The Tax on Vested and Net Vested Value outputs in this calculator apply your entered tax rate to the current vested value. Use your effective marginal tax rate — accounting for federal and state taxes — for the most realistic net-value estimate. If you are in the 24% federal bracket and pay 6% state income tax, entering 30% gives you a conservative after-tax view.

One common strategy is same-day sale (also called sell-to-cover): you sell enough shares at vesting to cover the tax withholding and keep the remainder. Another approach is to sell all vested shares immediately to avoid concentration risk, then reinvest the after-tax proceeds in a diversified portfolio. Whichever approach you choose, running the numbers in this RSU tax calculator before your vest date helps you avoid tax-time surprises.

The future value section of this calculator answers a key question: if the stock grows at your expected annual rate, what will your full grant be worth when it is completely vested? This projection uses the compound growth formula — multiplying the current price by one plus the growth rate raised to the power of years remaining — then multiplies by total shares to get total future value.

Choosing a realistic growth rate is critical. Looking at your company's historical stock performance, analyst consensus price targets, and broader sector trends can give you a reasonable range. Conservative analysts might use 5–8% for established large-cap companies; high-growth technology names might warrant 10–15% in optimistic scenarios. Stress-testing with multiple growth rates — say 0%, 8%, and 15% — shows you the full range of outcomes and prevents over-reliance on a single optimistic projection.

The future value figure displayed does not account for taxes on unvested shares, since those will be assessed at the fair market value on each future vest date, which is unknowable today. Think of it as a gross future value that you can discount by your expected tax rate for a conservative after-tax estimate.

Remember that stock prices are volatile. A projected future value based on steady compound growth will rarely match reality precisely. The calculator's projection is a planning tool, not a guarantee. Regularly updating your inputs as vest dates approach, as the stock price changes, or as your tax situation evolves keeps your plan current and actionable.

Employees sometimes receive both RSUs and stock options and need to understand how they differ. RSUs deliver shares (or cash) at vesting with no purchase required, so they always have value as long as the stock price is above zero. Stock options give you the right to buy shares at a fixed strike price; they only have intrinsic value when the market price exceeds that strike price.

Because RSUs have no purchase price, they carry less risk than underwater stock options. However, they also offer less upside leverage. A stock option with a $10 strike on a stock that goes to $50 generates a $40 gain per share. An RSU on the same stock generates a $50 gain per share — higher in absolute terms, but a smaller multiple of any initial cost since the cost basis is zero.

From a tax perspective, RSUs are typically simpler: income is recognized at vesting at the full fair market value, with no special elections required. Incentive Stock Options (ISOs) carry potential Alternative Minimum Tax (AMT) implications if held past the exercise date, adding complexity. Non-Qualified Stock Options (NQSOs) are taxed as ordinary income at exercise, similar to RSUs.

This restricted stock calculator focuses on RSU-style grants where you receive shares at vesting with no exercise required. If you hold NQSOs or ISOs, use the dedicated options calculator tools for accurate modeling of those instruments.
