1. What is an Early Mortgage Payoff Calculator with Biweekly Payments?

Definition: This calculator determines how many biweekly payments are needed to pay off a mortgage early by making half-payments every two weeks instead of monthly payments.

Purpose: It helps homeowners understand how biweekly payments can accelerate mortgage payoff and reduce total interest paid.

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:

\( n' \) — Reduced number of payments (unitless)
\( P \) — Principal loan amount (USD)
\( r \) — Periodic interest rate (decimal)
\( M_{bi} \) — Biweekly payment amount (USD)

Explanation: The formula calculates how many biweekly payments are needed to reduce the principal to zero, accounting for the more frequent payment schedule.

3. Benefits of Biweekly Payments

Details: Making biweekly payments results in 26 half-payments per year (equivalent to 13 monthly payments), which can shave years off your mortgage.

4. Using the Calculator

Tips: Enter the principal amount, interest rate (as decimal), and your planned biweekly payment. The calculator will show how many payments you'll need to make.

5. Frequently Asked Questions (FAQ)

Q1: How much faster will I pay off my mortgage?
A: Typically 4-8 years faster on a 30-year mortgage, depending on your interest rate and payment amount.

Q2: Is the interest rate monthly or annual?
A: Enter the periodic rate - for monthly calculations use annual rate/12, for biweekly use annual rate/26.

Q3: How do I convert my monthly payment to biweekly?
A: Divide your monthly payment by 2 to get the biweekly amount.

Q4: Will this save me money on interest?

Q5: Do all lenders accept biweekly payments?
A: Most do, but check with your lender about their specific policies and any fees.
