How to Use This Calculator
Using the Eastman Credit Union Auto Loan Calculator is simple:
- Enter the loan amount you need (the price of the vehicle minus any down payment).
- Input the interest rate offered by Eastman Credit Union (typically between 3% and 8%).
- Select the loan term in years (common options are 3, 4, 5, or 6 years).

The calculator uses the standard auto loan payment formula to provide accurate estimates. Remember that actual payments may vary based on your specific credit union terms and conditions.
Formula Used
The calculator uses the following formula to calculate your monthly auto loan payment:
Monthly Payment = P × (r(1 + r)^n) / ((1 + r)^n - 1)
Where:
- P = Principal loan amount (loan amount)
- r = Monthly interest rate (annual rate divided by 12)
- n = Number of payments (loan term in years × 12)
Additional calculations include:
- Total Interest = (Monthly Payment × n) - P
- Total Cost = Monthly Payment × n
Worked Example
Let's say you're financing a $25,000 car with a 5-year loan at 4.5% interest. Here's how the calculation works:
Example Calculation
Principal (P) = $25,000
Annual Interest Rate = 4.5%
Monthly Interest Rate (r) = 4.5% ÷ 12 = 0.375% or 0.00375
Number of Payments (n) = 5 years × 12 = 60
Monthly Payment = $25,000 × (0.00375(1 + 0.00375)^60) / ((1 + 0.00375)^60 - 1)
Monthly Payment ≈ $452.38
Total Interest = ($452.38 × 60) - $25,000 = $1,120.80
Total Cost = $452.38 × 60 = $26,120.80
This example shows that financing a $25,000 car with a 5-year loan at 4.5% interest would result in approximately $452.38 monthly payments, $1,120.80 in interest, and a total cost of $26,120.80.
