Borrowing and saving decisions are easier when you can see the whole picture: the monthly cost, the total interest and how the balance changes over time. These financial calculators use the standard formulas lenders and banks use, show their working, and explain what each result does and does not include.

Which Financial Calculator Do You Need?

  • Working out the monthly payment and total interest on a personal, car or other fixed-rate loan: use the loan calculator.
  • Estimating a full home loan payment with property tax, insurance, HOA and PMI: use the mortgage calculator.
  • Seeing how savings grow with interest on interest and regular deposits: use the compound interest calculator.
  • Working out interest on the original amount only, with I = PRT: use the simple interest calculator.
