What Is an Auto Loan?
An auto loan is a secured loan used to purchase a vehicle, where the vehicle itself serves as collateral. If you fail to make payments, the lender has the right to repossess the car to recover their losses. Understanding this financial product is crucial because it dictates your monthly budget and the total value of the asset over time.
In Minnesota, any lien on a vehicle must be registered with the Driver and Vehicle Services (DVS). Whether you are buying new or used, securing favorable terms on your car loan can save you thousands of dollars over the life of the loan.
How Minnesota Car Loan Costs Are Calculated
Several key factors determine the final amount you pay each month and over the life of the loan. Understanding these components helps you negotiate better deals.
- Vehicle Price: This is the negotiated sticker price of the car before any taxes or fees are applied.
- Minnesota Sales Tax: The state charges a general sales tax of 6.875%, plus local option taxes. Crucially, in Minnesota, you only pay sales tax on the difference between the new car price and your trade-in value.
- Interest Rate (APR): The annual percentage rate is the cost of borrowing money. A lower APR means lower monthly payments and less total interest paid.
- Loan Term: The length of the loan in months. Shorter terms (36 months) mean higher payments but less interest. Longer terms (72+ months) lower payments but increase total cost.
- Trade-in Value: The value the dealer gives you for your current car. This amount is deducted from the principal and reduces your taxable basis in MN.
How Our Minnesota Auto Loan Calculator Works
M = P[i(1+i)^n]/[(1+i)^n-1]
Where:
- M = Total monthly payment
- P = Principal loan amount
- i = Monthly interest rate (Annual Rate / 12)
- n = Number of payments over the loan term
To provide accurate estimates, our calculator first determines the taxable amount by subtracting your trade-in value from the purchase price. It then applies the Minnesota sales tax rate to find the total cost. Your down payment is subtracted from this total to establish the principal loan amount. Finally, we apply the amortization formula to calculate your monthly obligation, assuming fixed monthly compounding.
How to Use This Loan Calculator
Follow these simple steps to get an accurate picture of your future car payments:
- Enter the "Out-the-Door" price or the negotiated sticker price of the vehicle.
- Add your estimated Down Payment. This is the cash you pay upfront to reduce the loan amount.
- Enter your Trade-in Value if applicable. Remember, this lowers your taxable basis in Minnesota.
- Adjust the Interest Rate (APR) based on your credit tier (e.g., 4% for good credit, 10% for fair credit).
- Select your desired Loan Term in months (e.g., 60 months).
Pro Tip
Use the "Presets" feature to quickly compare how different interest rates or loan terms affect your monthly budget.
Understanding Your Auto Loan Results
Once you calculate your payment, compare it against your monthly net income to determine affordability.
< 10% of Monthly Net Income
Excellent/Conservative. This payment is highly affordable and leaves room in your budget for other expenses.
10% - 15% of Monthly Net Income
Manageable/Standard. This is the industry standard. It fits within a typical budget but requires careful management.
15% - 20% of Monthly Net Income
Stretched/High. Proceed with caution. This limits your financial flexibility for other needs.
> 20% of Monthly Net Income
Risky. High likelihood of financial stress. Consider a cheaper vehicle or larger down payment.
Total Interest Analysis: Pay attention to the "Total Interest" figure. If this amount exceeds 20% of the car's price, you are paying significantly more than the vehicle is worth. Try to increase your down payment or shorten the term to reduce this cost.
Minnesota Car Loan Rate & Term Benchmarks
Compare your calculated rate against current market averages to ensure you are getting a good deal.
| Credit Score Tier | Average APR (New) | Average APR (Used) |
|---|---|---|
| Excellent (720-850) | 3.5% - 5.0% | 4.0% - 6.0% |
| Good (660-719) | 6.0% - 8.0% | 7.5% - 9.5% |
| Fair (600-659) | 10.0% - 13.0% | 12.0% - 16.0% |
| Poor (Below 600) | 15.0% + | 18.0% + |
Average Loan Terms: New cars (~72 months), Used cars (~60 months). If your rate is higher than the average for your score tier, consider checking with a local Minnesota credit union for a better offer.
Why Your Loan Rate May Vary
- Credit Score: This is the primary driver of your APR. Scores below 660 often trigger significantly higher interest rates due to increased lender risk.
- Loan Term: Longer terms (72-84 months) lower your monthly payment but drastically increase the total interest paid. They also increase the risk of being "upside down" (owing more than the car is worth).
- Vehicle Age: Used cars generally carry higher APRs than new cars because their resale value is less predictable.
- Minnesota Factors: Your location within the state may impact rates. Rural vs. Urban credit union availability and local competition can sometimes offer better rates than large national banks.

Limitations of This Estimation
While this calculator provides a close estimate, please be aware of the following limitations:
- Fees Excluded: Documentation fees ($100-$500), registration/title fees, and GAP insurance are NOT included in the "Vehicle Price" input by default but affect the final "Out-the-Door" cost.

- Variable Rates: This calculator assumes a fixed interest rate. If you have a variable-rate loan, your payments may change over time.
