1. What is the Mortgage Payoff Calculator With Extra Payment?

The Mortgage Payoff Calculator With Extra Payment estimates how much faster you can pay off your mortgage by making additional payments. It calculates the reduced payoff time based on your regular payment, extra payment amount, current balance, and interest rate.

2. How Does the Calculator Work?

The calculator uses the following formula:

\[ \text{New Months} = \frac{\log\left(\frac{\text{PMT} + \text{Extra}}{\left(\text{PMT} + \text{Extra}\right) - \text{Balance} \times r}\right)}{\log\left(1 + r\right)} \]

Where:

\( \text{PMT} \) — Regular monthly payment (USD)
\( \text{Extra} \) — Additional monthly payment (USD)
\( \text{Balance} \) — Current mortgage balance (USD)
\( r \) — Monthly interest rate (decimal)

Explanation: The formula calculates how many months it will take to pay off the loan when making extra payments each month, accounting for the reduced principal and interest savings.

3. Importance of Extra Payments

Details: Making extra payments can significantly reduce the total interest paid and shorten the loan term. Even small additional payments can have a substantial impact over time.

4. Using the Calculator

Tips: Enter your regular monthly payment, the extra amount you plan to pay, your current balance, and the monthly interest rate (annual rate divided by 12). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How much can extra payments save me?
A: Extra payments can save thousands in interest and reduce your loan term by years, depending on the amount and timing of payments.

Q2: Is it better to make extra payments or refinance?
A: This depends on your interest rate, loan term, and how much extra you can pay. Use this calculator to compare scenarios.

Q3: Should I pay extra every month or make one annual payment?
A: Monthly extra payments typically save more interest because the principal is reduced sooner.

Q4: How does the monthly interest rate work?
A: Divide your annual rate by 12 (e.g., 6% annual = 0.06/12 = 0.005 monthly).

Q5: Are there prepayment penalties?
A: Most modern mortgages don't have prepayment penalties, but check your loan terms to be sure.
