1. What is the Loan Payment Formula?

The loan payment formula calculates the fixed monthly payment required to fully amortize a loan over its term. This standard formula is used by banks and financial institutions to determine loan payments.

2. How Does the Calculator Work?

The calculator uses the loan payment formula:

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

Where:

\( P \) — Principal loan amount (USD)
\( r \) — Monthly interest rate (annual rate ÷ 12)
\( n \) — Number of months (loan term in years × 12)
\( PMT \) — Monthly payment amount (USD)

Explanation: The formula accounts for both principal repayment and interest charges over the life of the loan, with interest being front-loaded in the payment schedule.

3. Importance of Loan Amortization

Details: Understanding loan amortization helps borrowers see how much of each payment goes toward principal vs. interest, the total cost of borrowing, and how extra payments can reduce the loan term and total interest.

4. Using the Calculator

Tips: Enter the loan amount in USD, annual interest rate as a percentage, and loan term in years. The calculator will show the monthly payment, total interest, and complete amortization schedule.

5. Frequently Asked Questions (FAQ)

Q1: How does making extra payments affect my loan?
A: Extra payments reduce the principal faster, decreasing total interest paid and potentially shortening the loan term.

Q2: What's the difference between interest rate and APR?
A: The interest rate is the cost of borrowing, while APR includes fees and other loan costs to show the true annual cost.

Q3: Why does most of my early payment go to interest?
A: Amortization schedules are front-loaded with interest because interest is calculated on the outstanding balance, which is highest at the beginning.

Q4: How does loan term affect payments?
A: Longer terms reduce monthly payments but increase total interest paid. Shorter terms have higher payments but lower total costs.

Q5: Can I change my payment frequency?
A: Some lenders allow biweekly payments (26 payments/year) which can reduce your loan term and interest compared to monthly payments.
