1. What is the Loan Payment Formula?

The loan payment formula calculates the fixed monthly payment required to fully repay a loan over its term, including both principal and interest. This is commonly used for home improvement loans, mortgages, and other installment loans.

2. How Does the Calculator Work?

The calculator uses the standard loan payment formula:

Where:

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

Explanation: The formula accounts for the time value of money, calculating equal payments that cover both principal and interest over the loan term.

3. Importance of Loan Calculation

Details: Understanding your monthly payment helps with budgeting and ensures the loan is affordable. It also allows comparison between different loan offers.

4. Using the Calculator

Tips: Enter the total loan amount, annual interest rate (without % sign), and loan term in years. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q2: What's the difference between APR and interest rate?
A: APR includes fees and other loan costs, while the interest rate is just the cost of borrowing the principal.

Q3: How does loan term affect payments?
A: Longer terms reduce monthly payments but increase total interest paid over the life of the loan.

Q4: Are there prepayment penalties?
A: Some loans charge fees for early payoff. Check your loan terms for details.

Q5: Can I change the payment frequency?
A: This calculator assumes monthly payments. Other frequencies require different calculations.
