1. What is Loan Amortization?

Loan amortization is the process of paying off a debt over time through regular payments. An amortization schedule shows how each payment is split between principal and interest, with the interest portion decreasing over time as the principal is paid down.

2. How Does the Calculator Work?

The calculator uses the standard loan payment formula:

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

Where:

\( PMT \) — Monthly payment amount
\( P \) — Principal loan amount
\( r \) — Monthly interest rate (annual rate ÷ 12)
\( n \) — Total number of payments (years × 12)

Explanation: The formula calculates the fixed payment amount required to fully pay off a loan over its term, accounting for compound interest.

3. Importance of Loan Calculation

Details: Understanding your loan payments helps with financial planning, comparing loan options, and determining affordability. It shows how much interest you'll pay over the life of the loan.

4. Using the Calculator

Tips: Enter the loan amount in dollars, annual interest rate as a percentage (e.g., 5.25 for 5.25%), and loan term in years. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why does most of my early payment go toward interest?
A: In the beginning, your balance is highest, so the interest calculated on that balance is largest. As you pay down principal, the interest portion decreases.

Q2: How can I pay less interest overall?
A: Make extra principal payments when possible, choose a shorter loan term, or negotiate a lower interest rate.

Q3: What's the difference between simple and compound interest?
A: Simple interest is calculated only on principal, while compound interest is calculated on principal plus accumulated interest.

Q4: How does loan term affect my payments?
A: Longer terms mean lower monthly payments but more total interest paid. Shorter terms mean higher payments but less total interest.

Q5: Can I calculate payments for different compounding periods?
A: This calculator assumes monthly compounding, which is standard for most loans. Other compounding periods would require a different formula.
