Formula Used
The calculator uses the standard auto loan payment formula:
Auto 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 months)
This formula calculates the fixed monthly payment for an auto loan with a fixed interest rate. The calculator then uses this monthly payment to determine the total interest paid and total cost of the loan.
Worked Example
Let's calculate an example auto loan with these parameters:
- Loan amount: $25,000
- Loan term: 60 months (5 years)
- Interest rate: 4.5% APR
Using the formula:
Calculation Steps
1. Convert annual rate to monthly: 4.5% ÷ 12 = 0.375% or 0.00375
2. Plug values into formula: 25000 × (0.00375(1 + 0.00375)^60) / ((1 + 0.00375)^60 - 1)
3. Calculate monthly payment: $452.38
4. Total interest paid: $3,142.80
5. Total cost of loan: $28,142.80
This example shows that for a $25,000 loan at 4.5% APR over 5 years, you would pay approximately $452.38 per month, with $3,142.80 going to interest.
Comparison Table
Compare different loan scenarios to see how changes affect your payments:
| Loan Amount | Term (months) | Interest Rate | Monthly Payment | Total Interest |
|---|---|---|---|---|
| $20,000 | 48 | 4.0% | $428.12 | $1,744.96 |
| $20,000 | 60 | 4.0% | $372.46 | $2,347.60 |
| $25,000 | 48 | 4.5% | $548.23 | $2,689.44 |
| $25,000 | 60 | 4.5% | $452.38 | $3,142.80 |
This comparison shows how longer terms and higher interest rates increase both monthly payments and total interest costs.
