HOW IT WORKS

A result to understand, not just read.

Enter the amount borrowed, nominal annual rate and term, then choose a payment frequency. The comparison table recalculates every schedule using the same principal, rate and term so the differences remain visible.

  • The selected frequency changes the periodic rate and the total number of scheduled payments.
  • Twice-monthly means 24 payments per year; every two weeks means 26 payments per year, so they are not the same schedule.
  • The projection assumes a level payment and a nominal annual rate divided by the number of payments per year.
  • Actual lenders may compound interest differently and may not offer every frequency shown.

FREQUENTLY ASKED QUESTIONS

Is biweekly the same as twice monthly?+

No. Biweekly creates 26 payments per year, while twice monthly creates 24.

Does the result include closing costs and insurance?+

No. It models principal and interest only. Add lender fees, taxes, insurance and other costs separately.

Why can my lender's payment differ?+

Lenders may use different compounding conventions, day counts, rounding, escrow charges or payment schedules.
