Finance Calculators

Calculators for everyday money questions: what a loan costs each month and how much interest your savings earn. Every calculator shows the formula it uses, so you can check the math yourself.

How to choose: use the loan calculator when you borrow a fixed amount at a fixed rate, such as a car loan or a personal loan. It gives the monthly payment, the total interest and a year-by-year amortization schedule. Use the simple interest calculator when interest is charged on the starting amount only. It can also solve for the principal, the rate or the time, counted in years, months or days. Use the compound interest calculator for savings and investments, where interest is added to the balance and then earns interest itself, with an optional monthly contribution. The results are estimates before taxes and fees and do not replace an offer from a lender.
