How to Use This Calculator

The calculator shows you the monthly payment amount, total interest paid over the loan term, and the total cost of the loan. The payment chart visualizes how your payments are allocated between principal and interest.

Formula Used

The calculator uses the standard auto loan payment formula:

Monthly 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)

Total interest is calculated as (monthly payment × number of payments) - principal loan amount.

Worked Example

Let's calculate a $25,000 loan at 5% interest over 5 years:

Monthly interest rate = 5% ÷ 12 = 0.4167%
Number of payments = 5 × 12 = 60
Monthly payment = $25,000 [ 0.004167(1.004167)^60 ] / [ (1.004167)^60 - 1 ] ≈ $476.50
Total interest = ($476.50 × 60) - $25,000 = $1,170
Total cost = $25,000 + $1,170 = $26,170

Example Results

For this $25,000 loan at 5% over 5 years:

Monthly payment: $476.50
Total interest: $1,170
Total cost: $26,170

Important Considerations

Actual Rates May Vary

Indiana Members Credit Union's actual rates may differ from the estimated rates you enter. Always confirm the exact terms with your loan officer.

Down Payment Impact

A larger down payment reduces your loan amount and total interest cost. Consider putting 10-20% down to save money.

Loan Term Selection

Shorter loan terms have lower monthly payments but higher total interest. Longer terms have higher monthly payments but lower total interest.

Additional Costs

Remember to factor in closing costs (typically 2-5% of loan amount) and insurance costs when comparing loan options.
