1. What is the Loan Payment Formula?

The loan payment formula calculates the fixed monthly payment required to pay off a $15,000 loan over a specified term at a given interest rate. It accounts for both principal and interest payments.

2. How Does the Calculator Work?

The calculator uses the loan payment formula:

Where:

• \( PMT \) — Monthly payment (USD)
• \( r \) — Monthly interest rate (annual rate ÷ 12, in decimal)
• \( n \) — Number of months (loan term)
• 15000 — Principal loan amount (USD)

Explanation: The formula calculates the fixed payment needed to fully amortize the loan over its term, accounting for compound interest.

3. Importance of Loan Payment Calculation

Details: Understanding your monthly payment helps with budgeting and financial planning. It shows how much of each payment goes toward principal vs. interest.

4. Using the Calculator

Tips: Enter the annual interest rate as a percentage (e.g., 5.25 for 5.25%) and the loan term in months (e.g., 60 for 5 years). Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How does interest rate affect my payment?
A: Higher rates increase your monthly payment. For example, at 5% for 60 months you'd pay $283.07, but at 10% it would be $318.71.

Q2: How does loan term affect my payment?
A: Longer terms reduce monthly payments but increase total interest paid. A 3-year loan at 5% costs $449.70/month while a 5-year loan at the same rate costs $283.07/month.

Q3: What's included in the monthly payment?
A: This calculation includes principal and interest only. Your actual payment may include insurance or fees if required by the lender.

Q4: How accurate is this calculator?
A: It provides precise calculations for fixed-rate loans. Variable-rate loans would require different calculations.

Q5: Can I use this for other loan amounts?
A: This calculator is specifically for $15,000 loans. The formula can be adapted by changing the principal amount.
