Enter the loan amount, annual interest rate, and term in years. The calculator applies the standard amortization formula to derive a fixed monthly payment. Biweekly payment is derived by multiplying the monthly payment by 12 and dividing by 26 (the number of biweekly periods in a year). This calculator assumes a fixed-rate, fully amortizing loan and does not account for fees, insurance, or escrow charges. For loans with variable rates or additional costs, consult your lender.
Making 26 biweekly payments per year is equivalent to 13 monthly payments. This pays off the loan faster and saves on total interest.
No. This calculator shows P&I only. Actual lender payments include origination fees, insurance, property taxes, and escrow—check your loan documents.
Higher interest rates increase your monthly payment and total interest. Even a 1% difference on a large loan adds thousands in interest over time.
Extra principal payments reduce the remaining balance faster, shaving months or years off the loan and cutting total interest significantly.
This calculator assumes a fixed rate. Variable-rate loans (ARMs) change over time; consult your lender for rate-adjustment schedules and impacts.
