1. What is the Amortizing Loan Payment Formula?

The amortizing loan payment formula calculates the fixed monthly payment required to pay off a home equity loan over a specified term. This payment includes both principal and interest components, with the interest portion decreasing and principal portion increasing over the loan term.

2. How Does the Calculator Work?

The calculator uses the standard amortization formula:

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

Where:

$ PMT $ — Monthly payment (currency/month)
$ P $ — Loan principal (currency)
$ r $ — Monthly interest rate (annual rate ÷ 12, expressed as decimal)
$ n $ — Total number of payments (years × 12)

Explanation: The formula calculates the fixed payment that will completely pay off the loan principal and all accrued interest over the specified term.

3. Importance of Monthly Payment Calculation

Details: Accurate monthly payment calculation is essential for budgeting, loan comparison, and ensuring the payment amount is affordable within your financial constraints.

4. Using the Calculator
