Free Personal Finance Calculators
Big money decisions are easier when you can see the numbers before you commit. These calculators let you test a mortgage at different rates and down payments, see how much interest a car loan really costs, and find out how long it takes to reach a savings goal with a fixed monthly deposit. Compound interest and retirement projections show how time and steady contributions add up, while the inflation calculator shows what today's money will buy in ten or twenty years.
For everyday spending, check the real price after a discount, add or remove sales tax, compare cost per ounce between two package sizes, split a restaurant bill with a tip, or convert a price into another currency before you travel. Each calculator explains its assumptions in plain English so you know what the figure includes and what it leaves out. Results are estimates for planning, not financial advice, and nothing you type is stored.
