Choose a calculator for a payment, goal or income comparison

Use the same currency for all amounts and check the assumed rate and payment timing. These tools model the inputs you provide; they do not select a lender, predict returns or calculate local taxes.

  • Mortgage calculator separates principal and interest from optional housing costs; use the loan calculator for a general fixed-rate balance.
  • Compound interest projects a balance from regular deposits; savings goal works backwards to the monthly amount needed.
  • Debt payoff estimates how long a fixed monthly payment takes to clear a balance with no new borrowing.
  • Hourly to salary annualizes an hourly wage; salary to hourly reverses the comparison using your chosen work schedule.
