Finance Tools

Calculators for real money decisions — loans, savings growth, and shopping costs.

These calculators cover the high-value financial questions people search for most: how much will my monthly payment be, how much will my savings grow, and how much will this cost after tax. All calculations run in your browser — nothing is sent anywhere.

Loan Payment Calculator
Enter loan amount, interest rate, and term to see your monthly payment, total paid, and total interest over the life of the loan.
Compound Interest Calculator
Calculate how an investment grows over time with compound interest. Choose compounding frequency and see final balance and total growth.
Sales Tax Calculator
Add sales tax to a price or reverse-calculate the pre-tax price from a total. Works for any tax rate.
