Crypto Capital Gains Tax Calculator

Crypto is taxed as property by the IRS. Short-term gains (< 1 year) are taxed as ordinary income; long-term gains get preferential rates.

What this calculator does

Holding crypto for over 1 year before selling can reduce your tax rate from 37% to as low as 0%.

When to use this calculator

Use this calculator before making any financial commitment that depends on this type of calculation. Running the numbers in advance lets you evaluate options without the pressure of a live negotiation or decision deadline.

Common mistakes

A frequent error is using annual rates where monthly rates are required (or vice versa). Simply dividing an annual rate by 12 is only an approximation — the correct conversion for compound calculations uses the (1 + r)^(1/12) − 1 formula.

Real-world scenarios

A first-time buyer models three scenarios before making an offer: 10%, 15%, and 20% deposit on a £280,000 property. The calculator shows exactly how the monthly payment and total interest cost change with each deposit level, making the decision visible rather than speculative.

Frequently asked questions

Do I pay tax on crypto gains?

Yes. The IRS treats crypto as property. Any sale at a profit triggers capital gains tax.
