How to use this loan payment calculator

Use it when you want quick answers to “what is my monthly payment,” “how much interest will I pay,” and “how does term length change the cost.” It suits level-payment loans where the rate stays fixed for the whole payoff window.

  1. Enter loan amount (principal borrowed).
  2. Enter annual interest rate as a percent (APR-style input for the nominal yearly rate).
  3. Select term in years or months.
  4. Optional start month labels rows in the amortization table.

Expand Show Full Schedule to audit principal vs interest period by period. Remember: real mortgages often add taxes, insurance, and HOA outside this principal-and-interest core.

Fixed amortization formula

Payments follow the standard amortizing loan identity: solve for the payment that zeros the balance after n periods at rate r per period. Early periods pay more interest; later ones chip away more principal when the rate is fixed.
