Formula Explained

The calculation for auto loan monthly payments is based on the standard mortgage formula:

Monthly Payment = P × (r(1 + r)^n) / ((1 + r)^n - 1)

Where:

P = Principal loan amount
r = Monthly interest rate (annual rate divided by 12)
n = Number of payments (loan term in years × 12)

This formula accounts for the fact that interest is paid on the remaining balance each month, which is why the payment amount decreases slightly over time.

Worked Example

Let's look at an example to see how this works in practice.

Example Scenario

Loan Amount: $25,000

Annual Interest Rate: 5.5%

Loan Term: 5 years

Using the formula:

Convert annual rate to monthly: 5.5% ÷ 12 = 0.4583% or 0.004583
Calculate number of payments: 5 years × 12 = 60 payments
Plug values into formula: $25,000 × (0.004583(1 + 0.004583)^60) / ((1 + 0.004583)^60 - 1)
Result: $472.98 per month

Over the 5-year term, you would pay a total of $28,378.80, with $3,378.80 going toward interest.

Frequently Asked Questions

What factors affect my auto loan monthly payment?

Several factors influence your monthly payment, including the loan amount, interest rate, loan term, and any fees or down payment you make. Generally, lower interest rates and longer loan terms result in smaller monthly payments.

Is it better to get a longer or shorter loan term?

A shorter loan term typically results in lower monthly payments but means you'll pay more in interest over time. A longer term may mean higher monthly payments but less total interest paid. Consider your financial situation and how long you plan to keep the vehicle.

How do I compare different loan offers?

Use this calculator to compare monthly payments for different loan amounts, interest rates, and terms. Look at the total interest paid and the total cost of the loan to make an informed decision.

What's the difference between APR and interest rate?

APR (Annual Percentage Rate) is the total cost of credit, including fees and interest, while the interest rate is just the interest portion. APR is typically higher than the stated interest rate because it includes additional costs.
