The calculator uses the standard auto loan formula to provide accurate estimates. Remember that actual loan terms may vary based on your creditworthiness and the specific loan offer from Educators Credit Union.
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 years × 12)
This formula calculates the fixed monthly payment for an auto loan with a fixed interest rate. The total interest paid is the total amount paid minus the original loan amount.
Worked Example
Let's calculate a $25,000 auto loan at 5% annual interest for 5 years:
- Principal (P) = $25,000
- Annual interest rate = 5% or 0.05
- Monthly interest rate (r) = 0.05 ÷ 12 ≈ 0.004167
- Number of payments (n) = 5 years × 12 = 60 months
Plugging these into the formula:
Calculation Steps
Monthly Payment = $25,000 × (0.004167(1 + 0.004167)^60) / ((1 + 0.004167)^60 - 1)
≈ $25,000 × (0.004167 × 1.2456) / (1.2456 - 1)
≈ $25,000 × (0.005189) / 0.2456
≈ $25,000 × 0.02112 ≈ $528.00
Your estimated monthly payment would be $528.00, with a total interest of $1,800.00 over the life of the loan.
Loan Comparison Table
Compare different loan scenarios to see how changes in interest rate or loan term affect your payments:
| Loan Amount | Interest Rate | Loan Term | Monthly Payment | Total Interest |
|---|---|---|---|---|
| $20,000 | 4.5% | 5 years | $380.50 | $1,800.00 |
| $20,000 | 4.5% | 7 years | $273.00 | $2,520.00 |
| $20,000 | 6.0% | 5 years | $416.00 | $2,400.00 |
| $30,000 | 4.5% | 5 years | $570.75 | $2,700.00 |
This table shows how different loan terms and interest rates affect your monthly payments and total interest paid. Shorter loan terms generally result in higher monthly payments but less total interest.
