The calculator will display your monthly payment, total interest paid over the loan term, and the total amount paid (principal + interest).
Formula Used
The monthly car payment is calculated using the standard loan payment formula:
M = P [ i(1 + i)n ] / [ (1 + i)n - 1 ]
Where:
- M = Monthly payment
- P = Principal loan amount
- i = Monthly interest rate (annual rate divided by 12)
- n = Number of payments (loan term in years × 12)
This formula accounts for the interest charged on the outstanding loan balance each month.
Worked Example
Let's calculate a monthly payment for a $25,000 car loan with a 4.5% annual interest rate over 5 years:
- Principal (P) = $25,000
- Annual interest rate = 4.5% or 0.045
- Monthly interest rate (i) = 0.045/12 ≈ 0.00379
- Number of payments (n) = 5 × 12 = 60
Plugging these values into the formula:
M = 25000 [ 0.00379(1 + 0.00379)60 ] / [ (1 + 0.00379)60 - 1 ]
M ≈ $452.34 per month
Over 5 years, you would pay approximately $27,140 in total, with $2,140 going to interest.
Loan Term Comparison
Compare how different loan terms affect your monthly payments for a $25,000 loan at 4.5% interest:
| Loan Term | Monthly Payment | Total Interest | Total Amount Paid |
|---|---|---|---|
| 3 years (36 months) | $725.50 | $2,534.00 | $27,534.00 |
| 4 years (48 months) | $583.33 | $3,400.00 | $28,400.00 |
| 5 years (60 months) | $452.34 | $2,140.00 | $27,140.00 |
| 6 years (72 months) | $375.00 | $1,500.00 | $26,500.00 |
| 7 years (84 months) | $323.00 | $1,100.00 | $26,100.00 |
Shorter loan terms result in higher monthly payments but lower total interest costs. Longer loan terms reduce monthly payments but increase total interest paid.
Frequently Asked Questions
What is the best car loan term?
The best loan term depends on your financial situation. Shorter terms (3-4 years) can save you money on interest, while longer terms (5-7 years) may be more affordable monthly payments. Consider your budget and ability to pay off the loan early.
How do I get the best interest rate on a car loan?
To get the best interest rate:
- Improve your credit score before applying
