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. It accounts for the principal amount, interest rate, and loan duration.

2. How Does the Calculator Work?

The calculator uses the standard loan payment formula:

Where:

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

Explanation: The formula calculates the fixed payment that covers both principal and interest each month, with more going toward interest early in the loan term.

3. Importance of Loan Payment Calculation

Details: Understanding your monthly payment helps with budgeting and financial planning. The payment table shows how each payment is split between principal and interest over time.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Why does most of my payment go toward interest at first?
A: This is how amortization works - early payments cover more interest because the outstanding balance is higher. The ratio shifts toward principal over time.

Q2: How can I pay less interest overall?
A: Make extra principal payments, choose a shorter loan term, or secure a lower interest rate to reduce total interest paid.

Q3: What's the difference between APR and interest rate?
A: The interest rate is the cost of borrowing, while APR includes fees and other loan costs to show the true annual cost.

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

Q5: How does loan term affect payments?
A: Shorter terms mean higher monthly payments but less total interest. Longer terms reduce monthly payments but increase total interest.
