About Taxes calculators

Tax can quietly take a large slice of income and gains, so it pays to estimate it in advance. These calculators help you work out income tax, take-home pay, capital gains and sales tax so there are no surprises.

Estimate your income tax and effective rate, see your real take-home pay after deductions, and model capital gains before you sell so you can plan the timing. Sales tax, dividend tax and marginal-rate tools round out the set for both US and UK rules where relevant.

Taxes calculators: frequently asked questions

What is the difference between marginal and effective tax rate?

Your marginal rate is the tax on your next dollar of income, the top bracket you reach. Your effective rate is the average across all your income, which is lower because earlier brackets are taxed less. The calculators show both so you do not overestimate your bill.

How is capital gains tax calculated?

It applies to the profit when you sell an asset for more than you paid, with the rate often depending on how long you held it. Holding longer can mean a lower long-term rate. The capital gains calculator estimates the tax from your buy and sell figures.

Why is my take-home pay lower than my salary?

Gross salary is reduced by income tax, social security or national insurance, and any pension or benefit deductions. What lands in your account is the net figure. The take-home and paycheck calculators break down every deduction.
