Formula Explained
The calculation for your monthly auto payment is based on the standard loan amortization formula:
Monthly Payment Formula
M = P [ i(1 + i)^n ] / [ (1 + i)^n - 1 ]
Where:
- M = Monthly payment
- P = Principal loan amount (Loan Amount - Down Payment)
- i = Monthly interest rate (Annual Rate / 12 / 100)
- n = Number of payments (75 months)
This formula calculates the fixed monthly payment required to pay off the loan over the specified term, including interest.
Worked Example
Let's walk through an example to see how the calculator works:
Suppose you're taking out a $25,000 loan with a 5% annual interest rate and a $2,500 down payment. Here's how the calculation would work:
- Principal (P) = $25,000 - $2,500 = $22,500
- Monthly interest rate (i) = 5% / 12 / 100 = 0.004167
- Number of payments (n) = 75
- Plugging these values into the formula: M = $22,500 [ 0.004167(1 + 0.004167)^75 ] / [ (1 + 0.004167)^75 - 1 ]
- Calculating this gives you a monthly payment of approximately $375.45
Using the calculator with these values would show you this result, along with the total interest paid over the 75-month term.
