Financial Calculators
Free financial calculators
Money decisions are easier when you can see the numbers. These free financial calculators cover the big everyday questions — what a loan or mortgage will cost each month, how fast savings grow, how long it takes to clear a debt, what a salary works out to, and how much VAT to add or remove. Each runs in your browser, updates as you type, and comes with a plain-English explanation of the formula behind it.
Loans and mortgages use the standard amortization formula; savings use month-by-month compounding; and the debt calculator simulates your balance month by month. Where a figure depends on your lender or country — an APR, a tax rate — we say so. Pick a tool below to get started, or read our guides for the ideas behind the numbers.
