RSU & Equity Calculator

Estimate the income tax and National Insurance due when your RSUs vest, and see how that income stacks on top of your salary.

You are not taxed twice on RSUs
RSUs are taxed as income at vest (income tax + NI on the vest-day value). Your cost basis then resets to the vest price — only the gain (or loss) after vesting is subject to Capital Gains Tax when you sell.

Add RSU income in Settings to project your vesting schedule. RSUs are taxed as income (tax + NI) at vest, and your cost basis resets to the vest price for any future CGT.
