A tool for your next question
Finance calculators
Start with the money question you want to answer. Compare borrowing costs, explore a savings plan, or estimate what remains from your salary. Each tool explains the assumptions behind its result.

Compare the required payment with the total cost of borrowing. A smaller monthly payment can still mean more interest over a longer term.

Compare like with like
Use the same currency, timing and included costs when comparing results. A mortgage interest rate differs from an APR that includes borrowing fees. A nominal savings rate differs from an effective APY or AER. Changing a currency label does not convert money.
Keep the assumptions with the answer
For a mortgage, record principal, rate convention, amortization and extra payments. For savings, record deposit timing and the type of annual rate. The upgraded mortgage and compound interest tools let you copy this context and download a monthly schedule.
