The Loan Payment Formula

To calculate the fixed monthly payment for a loan, we use the standard amortization formula. This mathematical equation ensures that each payment you make is consistent and covers both the principal and the interest owed for that period.

• P (Principal): The initial amount of money you borrowed.
• r (Monthly Interest Rate): The annual interest rate divided by 12. For example, a 6% annual rate becomes a 0.5% (or 0.005) monthly rate.
• n (Number of Payments): The total number of months in your loan term. A 30-year loan has 360 monthly payments (30 * 12).

5. FAQs

Q1: What does the amortization schedule show?
The amortization schedule provides a detailed, month-by-month table showing how each of your payments is divided between paying down the principal (the amount you borrowed) and paying the interest. It also shows your remaining loan balance after each payment.

Q2: How accurate is this calculator?
This calculator uses the standard, industry-wide formula for calculating loan payments. It provides a very accurate estimate for fixed-rate loans. Note that it does not account for additional fees like property taxes or insurance that may be included in a real-world mortgage payment (PITI).

Q3: Can I use this for variable-rate loans?
This tool is designed for fixed-rate loans, where the interest rate remains the same for the entire term. For variable-rate loans, the payment amount would change when the interest rate adjusts, which this calculator does not model.

Q4: What is the “Comparison Chart”?
The Comparison Chart is a powerful “what-if” tool. It automatically plots your loan’s balance over time alongside a hypothetical scenario where the interest rate is 1% lower. This instantly visualizes the potential savings and demonstrates the significant impact a lower interest rate can have on your total cost.

Q5: Is my data saved?
