Calculators for money and everyday math

Big money decisions — a car loan, a home, a savings plan — are easier when you can see the numbers. These calculators show your monthly payment, total interest and a year-by-year schedule, so you can compare options side by side before you talk to a bank.

Everyday math is covered too: percentages for discounts, tips and price changes, and an exact age calculator. Results update instantly as you type, and your numbers never leave your device. All results are estimates for information only, not financial advice.

Quick tips

  • Compare a 15-year and a 30-year mortgage to see how much interest a shorter loan could save you.
  • Add even a small monthly amount in the Compound Interest Calculator — over 20 years it makes a big difference.
  • Working out a sale price? Use “What is X% of Y” to find the discount, then subtract it.
