Personal Finance Calculators

These calculators help with the money decisions that cost the most when you get them wrong: what you'll take home from each paycheck, how much a loan really costs once fees are counted, what a car will cost over the whole finance deal, how much house you can afford and whether renting or buying leaves you better off, whether refinancing pays, and the fastest way out of debt. Planning ahead, there are retirement, life insurance and savings goal calculators.

Each one follows the rules where you live. For the US: 2026 federal and state income tax for all 50 states, sales tax by state, 401(k) limits, debt-to-income limits and PMI. For the UK: take-home pay, Stamp Duty and VAT at the 2026/27 rates from GOV.UK, workplace pensions and the State Pension, ISAs, income multiples and PCP balloon payments. Each explains its method and sources and the date it was last reviewed, and everything is calculated in your browser, so your figures stay private.

The results are estimates for planning, not financial or tax advice: lenders' offers, insurers' prices and your payroll depend on details only they have. For mortgages, savings and investments, see our mortgage, compound interest and EMI calculators too.
