1. What is a Biweekly Pay Off Mortgage Early Calculator?

Definition: This calculator estimates how quickly you can pay off your mortgage by making biweekly payments instead of monthly payments.

Purpose: It helps homeowners understand the time savings and interest reduction possible with accelerated biweekly payment schedules.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ n' = \frac{-\log\left(1 - \frac{P \times r}{M_{bi} \times \frac{26}{12}}\right)}{\log(1 + r)} \]

Where:

\( n' \) — Number of biweekly periods to payoff
\( P \) — Principal loan amount (USD)
\( r \) — Biweekly interest rate (annual rate ÷ 26)
\( M_{bi} \) — Biweekly payment amount (USD)

Explanation: The formula calculates how many biweekly payments are needed to fully amortize the loan based on the payment amount.

3. Importance of Biweekly Mortgage Payments

Details: Making biweekly payments (half your monthly payment every 2 weeks) results in 26 half-payments per year, equivalent to 13 full monthly payments. This extra payment each year can significantly reduce your loan term and total interest paid.

4. Using the Calculator

Tips: Enter your principal loan amount, annual interest rate (as a decimal, e.g., 0.05 for 5%), and your planned biweekly payment amount. All values must be > 0.
