Financial Calculators

Money decisions are easier when you can see the numbers before you commit. The financial calculators below cover the questions most households face: what a home or car will really cost per month, how long a loan takes to repay, how savings grow with compound interest, and how pay, tips, discounts and sales tax change what you take home or spend.

Every calculator has a written guide that explains the formula, walks through a worked example, lists the assumptions and links to authoritative sources such as consumer protection and tax agencies. Results are estimates meant to support your planning, so confirm final figures with your lender or a licensed professional.

How to choose the right calculator

Buying a home

Start with the house affordability calculator to set a realistic budget, then use the mortgage calculator to test rates and down payments, the amortization calculator to see how extra payments save interest, and the refinance calculator if you already have a loan.

Borrowing for a car or personal need

The auto loan and loan calculators show the monthly payment and total interest, so you can compare a longer, cheaper-per-month term against a shorter, cheaper-overall one.

Saving and investing

Use the compound interest, investment and retirement calculators to see how time, contributions and inflation interact over decades.
