How to Use This Calculator
Our free auto loan calculator is easy to use. Follow these simple steps to get your estimated monthly payments:
- Enter the loan amount you're requesting in the "Loan Amount" field.
- Input the annual interest rate offered by the lender in the "Interest Rate" field.
- Specify the loan term in years in the "Loan Term" field.
- Click the "Calculate" button to see your estimated monthly payments and total interest paid.
The calculator will display your estimated monthly payment and the total amount of interest you'll pay over the life of the loan. You can also see a breakdown of how your payments are allocated between principal and interest.
Formula Used
The auto loan calculator uses the standard mortgage payment formula to calculate your monthly payments:
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 multiplied by 12)
This formula calculates the fixed monthly payment required to pay off the loan over the specified term, including both principal and interest.
Worked Example
Let's look at an example to see how the auto loan calculator works. Suppose you're applying for a $25,000 auto loan with a 5% annual interest rate and a 5-year term.
- Enter $25,000 as the loan amount.
- Enter 5% as the interest rate.
- Enter 5 as the loan term.
- Click "Calculate".
The calculator will show that your estimated monthly payment is $462.45. Over the 5-year term, you'll pay a total of $1,109.80 in interest.
| Payment | Principal | Interest | Balance |
|---|---|---|---|
| 1 | $412.45 | $50.00 | $24,587.55 |
| 2 | $419.86 | $42.59 | $24,167.69 |
| 3 | $427.28 | $35.17 | $23,740.41 |
| 4 | $434.70 | $27.75 | $23,305.71 |
| 5 | $442.13 | $20.32 | $22,863.58 |
This table shows the first five payments of your loan, with the amount going toward principal and interest each month, and the remaining balance after each payment.
