1. What is the Mortgage Balance Formula?

The mortgage balance formula calculates the remaining principal balance on a loan after a certain number of payments have been made. It accounts for both the interest accrued and the principal paid down over time.

2. How Does the Calculator Work?

The calculator uses the mortgage balance formula:

\[ Balance = P \times (1 + r)^n - PMT \times \frac{(1 + r)^n - 1}{r} \]

Where:

$ P $ — Original principal loan amount ($)
$ r $ — Monthly interest rate (annual rate ÷ 12 ÷ 100)
$ n $ — Number of monthly payments made
$ PMT $ — Monthly payment amount ($)

Explanation: The formula calculates how much of the original principal remains after accounting for both interest growth and payment reductions.

3. Importance of Mortgage Balance Calculation

Details: Knowing your remaining mortgage balance is crucial for refinancing decisions, home equity calculations, prepayment planning, and understanding your overall financial position.

4. Using the Calculator

Tips: Enter the original loan amount, annual interest rate, number of monthly payments made, and your monthly payment amount. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why does my balance calculation differ from my lender's statement?
A: Small differences can occur due to rounding, payment application methods, or if extra payments were made that weren't accounted for in the calculation.

Q2: What if I've made additional principal payments?
A: This calculator assumes consistent monthly payments. For irregular or extra payments, you would need to track each payment individually.

Q3: How does interest rate affect the balance?
A: Higher interest rates mean more of your payment goes toward interest initially, resulting in slower principal reduction and a higher remaining balance.

Q4: Can I use this for other types of loans?
A: Yes, this formula works for any amortizing loan with fixed monthly payments, including auto loans and personal loans.

Q5: What does a negative balance mean?
A: A negative balance would indicate overpayment - you've paid more than the remaining principal plus interest. The calculator prevents negative results.
