Free Finance & Money Calculators
Free finance and money calculators for the everyday questions behind saving, borrowing, and pricing. Estimate how savings grow with the compound interest calculator, work out a fixed monthly payment with the loan payment calculator, plan toward a target with the savings goal calculator, or check simple interest, sales tax, tip, profit margin, and hourly-to-salary conversions. Each tool shows the standard formula (such as the amortization formula behind a loan payment) and worked examples so you can follow the math. Important: these are educational estimates based only on the numbers you enter and the formula shown — they ignore fees, taxes, and individual circumstances, are not financial advice, and you should confirm any figure with a qualified professional before acting on it.
See how an amount grows over time with compound interest, including optional regular contributions. The result separates your deposits from the interest earned.
Find the final price and the amount you save from a percentage discount.
Turn an hourly wage into an estimated annual, monthly, and weekly salary based on how many hours you work per week.
Estimate the monthly payment on a fixed-rate loan, plus the total you’ll pay and how much of that is interest. Works for auto loans, personal loans, and mortgages.
Enter your cost and selling price to see the profit, the profit margin, and the markup — the three numbers behind any pricing decision.
Find the hourly rate that an annual salary works out to, based on how many hours you work per week.
Add sales tax to a price using a rate you enter, and see the tax amount and the final total. Works for VAT and GST too.
Work out how much you need to save each month to reach a savings goal by a target date, allowing for a starting balance and an assumed interest rate.
Calculate simple interest — interest charged only on the original principal — and the total amount owed or earned.
Work out the tip and total for a bill, and split it evenly between any number of people.
