Planning to buy a car in Wisconsin? Use our auto loan calculator to estimate your monthly payments, total interest, and loan cost. This tool helps you understand your financing options before applying for a loan.
How to Use This Calculator
Enter the loan amount, interest rate, and loan term to calculate your monthly payments. The calculator shows:
- Monthly payment amount
- Total interest paid over the loan term
- Total cost of the loan (principal + interest)
- A breakdown of principal and interest payments over time
Use these results to compare different loan options and understand your financial commitment.
Note: This calculator provides estimates only. Actual loan terms may vary based on your credit score, down payment, and lender requirements.
Formula Used
The monthly payment is calculated using 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 ÷ 100)
- 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 auto loan at 4.5% APR for 5 years (60 months):
- Monthly interest rate = 4.5% ÷ 12 = 0.00375 (0.375%)
- Monthly payment = $25,000 × (0.00375(1 + 0.00375)^60) / ((1 + 0.00375)^60 - 1) ≈ $452.34
- Total interest = ($452.34 × 60) - $25,000 ≈ $1,111.40
- Total cost = $25,000 + $1,111.40 = $26,111.40
This example shows you would pay approximately $452.34 per month with $1,111.40 in total interest.

Wisconsin has some unique auto loan requirements:
- Minimum down payment requirements vary by lender (typically 3-10% of vehicle price)
