Biweekly Mortgage Calculator

Models the biweekly trick: paying half the monthly amount every two weeks yields 13 full payments a year instead of 12, quietly shortening the loan and cutting interest.

Notes

  • The saving comes purely from the extra 13th payment — the same result as a 1/12 monthly overpayment.
  • This is an educational estimate, not financial advice; talk to a qualified adviser before making money decisions.
