FAQ

  1. 1.

    What is the difference between equal payment and equal principal?

    Equal payment (amortization) has fixed monthly payments with more interest early on. Equal principal has fixed principal payments with decreasing monthly totals and less total interest.

  2. 2.

    Are the calculation results accurate?

    The formulas are based on standard financial equations and results are for reference only. Actual loan rates and terms depend on your bank contract.
