Formula Used
The auto loan calculator uses the standard loan payment formula:
Monthly Payment = P × (r(1 + r)^n) / ((1 + r)^n - 1)
Where:
- P = Principal loan amount
- r = Monthly interest rate (annual rate ÷ 12)
- n = Number of payments (loan term in years × 12)
This formula calculates the fixed monthly payment for a loan with a fixed interest rate.
Worked Example
Let's calculate a $25,000 auto loan with a 5% annual interest rate over 5 years:
- Principal (P) = $25,000
- Annual interest rate = 5% (0.05)
- Monthly interest rate (r) = 0.05 ÷ 12 = 0.004167
- Number of payments (n) = 5 × 12 = 60
Plugging these into the formula:
Monthly Payment = $25,000 × (0.004167(1 + 0.004167)^60) / ((1 + 0.004167)^60 - 1)
Monthly Payment ≈ $464.38
Total interest paid would be $2,706.40, and total loan cost would be $27,706.40.
Comparison Table
Here's how different loan terms affect your monthly payments for a $25,000 loan at 5% interest:
| Loan Term | Monthly Payment | Total Interest | Total Cost |
|---|---|---|---|
| 3 years (36 months) | $736.56 | $3,796.16 | $28,796.16 |
| 4 years (48 months) | $589.29 | $4,284.68 | $29,284.68 |
| 5 years (60 months) | $464.38 | $2,706.40 | $27,706.40 |
| 6 years (72 months) | $395.79 | $1,816.68 | $26,816.68 |
| 7 years (84 months) | $348.06 | $1,130.64 | $26,130.64 |
Shorter loan terms result in higher monthly payments but less total interest paid.
