Financial calculators

Each tool uses the numbers you enter and standard amortization or compound-growth formulas. Results stay on your device. They are estimates, not loan offers or investment advice.

How the estimates work

Each calculator uses the values you type and a documented formula. Mortgage and loan tools amortize principal and interest. Compound-interest and investment tools grow a balance by a rate you choose. Credit-card payoff estimates how long a payment takes to clear a balance. None of the outputs is a loan offer, rate quote, or investment recommendation.
