How this calculator works

Each month, interest is the remaining balance multiplied by the annual rate divided by twelve. Whatever is left of the fixed payment reduces the balance. Because the balance shrinks, the interest share falls a little every month and the principal share grows.

The yearly view adds up the monthly rows, so the last column is the balance at the end of that year. Total interest is the sum of every interest amount across the term.

What it can't tell you

  • This is principal and interest only. Your real monthly payment likely also includes property taxes, homeowners insurance, mortgage insurance and possibly HOA dues.
  • Adjustable-rate loans, interest-only periods and balloon structures do not follow this schedule.
  • Servicers apply payments on their own posting schedules, so real statements can differ by small amounts.
  • Extra principal changes the schedule — use the extra payment calculator to model that.
