Calculate RSU value at vesting, estimate tax withholding, and determine net shares or cash received from restricted stock unit grants.
Restricted Stock Units (RSUs) are a popular form of equity compensation that grant employees shares of stock upon vesting. Unlike stock options, RSUs have inherent value as long as the stock price is above zero, making them a more predictable form of compensation.
When RSUs vest, the full value is treated as ordinary income and subject to tax withholding. Most companies withhold taxes by selling a portion of the vesting shares (sell-to-cover), leaving the employee with fewer shares than the original grant.
This calculator determines the gross value of your RSUs at vesting, estimates the tax withholding, and computes the net value you actually receive. This is invaluable for financial planning, tax preparation, and understanding the true value of RSU-heavy compensation packages common in the technology industry. Whether you are a beginner or experienced professional, this free online tool provides instant, reliable results without manual computation. By automating the calculation, you save time and reduce the risk of costly errors in your planning and decision-making process.
RSU grants look impressive on paper, but taxes take a significant bite at vesting. This calculator shows you exactly how many shares or dollars you'll keep after withholding, so you can plan your finances and tax strategy accordingly. Having a precise figure at your fingertips empowers better planning and more confident decisions.
Gross Value at Vest = Shares Vesting × Stock Price Tax Withholding = Gross Value × (Tax Rate ÷ 100) Net Value = Gross Value − Tax Withholding Net Shares (Sell-to-Cover) = Shares × (1 − Tax Rate ÷ 100)
Result: $18,000 net value
When 200 RSUs vest at $150/share, the gross value is $30,000. At a 40% combined tax rate, approximately $12,000 is withheld for taxes. Net value is $18,000, or roughly 120 shares retained after sell-to-cover withholding.
RSUs are straightforward in concept — you receive shares at vesting — but the tax implications significantly reduce the net benefit. Understanding the math behind RSU taxation helps you plan effectively and avoid surprises at tax time.
Most companies use sell-to-cover withholding, but some allow you to pay taxes out of pocket and keep all shares. Consider whether the additional concentration in your employer's stock is worth the cash outlay. Diversification is generally recommended.
For employees with recurring RSU grants, create a vesting schedule that shows expected gross and net values for each upcoming vest date. This helps with cash flow planning, estimated tax payments, and overall financial planning.
RSUs are taxed as ordinary income at vesting. The gross value (shares × price at vest) is added to your W-2 income. Federal, state, and FICA taxes are withheld, typically through sell-to-cover where a portion of shares are sold to pay taxes.
Sell-to-cover is a common withholding method where the company sells enough of your vesting shares to cover the estimated tax obligation. You receive the remaining shares. This avoids out-of-pocket cash for tax payments.
Your cost basis is the stock price on the vest date. If you sell the shares later at a higher price, the gain above the vest price is taxed as capital gains (short-term or long-term depending on holding period).
Yes. Unlike stock options that can be underwater, RSUs always have value as long as the stock trades above $0. However, the value at vesting may be less than originally projected if the stock price declines.
Many financial advisors recommend selling at vest to avoid concentration risk. Holding is essentially a decision to invest in your company's stock. If you wouldn't buy the stock at its current price, you probably shouldn't hold it.
Add your federal marginal rate (22–37%), state income tax rate, and FICA (7.65% up to the Social Security wage base, 1.45% above). For high earners, the total often falls between 35–50%.
