1. What is a Mortgage Payoff Calculator?

Definition: This calculator determines how long it will take to pay off your mortgage based on your monthly payment amount, principal, and interest rate.

Purpose: Helps homeowners understand their mortgage timeline and how extra payments can accelerate payoff (Dave Ramsey's debt-free approach).

2. How Does the Calculator Work?

The calculator uses the Ramsey payoff formula:

Where:

• \( n \) — Number of payments (unitless)
• \( M \) — Monthly payment (USD)
• \( P \) — Principal amount (USD)
• \( r \) — Monthly interest rate (decimal)

Explanation: The formula calculates how many payments are needed to reduce the principal to zero given a fixed payment amount and interest rate.

3. Importance of Mortgage Payoff Calculation

Details: Understanding your payoff timeline helps with financial planning, shows the impact of extra payments, and motivates debt-free living.

4. Using the Calculator

Tips: Enter your regular monthly payment (including any extra principal), current loan balance, and annual interest rate. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: How can I pay off my mortgage faster?
A: Make biweekly payments instead of monthly, or add extra principal to each payment (Dave Ramsey's "debt snowball" method).

Q2: Why does my payment need to be greater than the interest?
A: Otherwise, you're not reducing the principal and will never pay off the loan (negative amortization).

Q3: How accurate is this calculator?
A: It provides a close estimate assuming fixed payments and interest rate. Actual results may vary with rate changes or payment adjustments.

Q4: Should I pay off my mortgage early?
A: Dave Ramsey recommends paying off all debt (including mortgages) before investing, except for retirement matching.

Q5: How much will extra payments save me?
A: Try increasing your monthly payment amount to see how it reduces your payoff timeline and total interest paid.
