Minnesota Auto Loan Calculator (with Minnesota Sales Tax & Fees)

Minnesota applies its general state sales tax rate of 6.875% to most motor vehicle purchases through what the state calls the Motor Vehicle Sales Tax, collected at the time of titling rather than folded into a retailer's point-of-sale receipt. That 6.875% figure includes the statewide 6.5% general sales tax plus additional dedicated tax fractions the legislature has layered on over the years, which is why Minnesota's vehicle tax rate looks slightly unusual compared to a clean round number.

Beyond sales tax, Minnesota's annual vehicle registration system works differently from a flat renewal fee. The state charges a base registration tax plus an additional amount tied to the vehicle's original manufacturer's suggested retail price (MSRP) that declines each year as the car ages, meaning new and recently purchased vehicles carry meaningfully higher annual tab renewal costs than older ones, even before considering vehicle weight or class differences.

This calculator applies the 6.875% Motor Vehicle Sales Tax to the full purchase price, adds a flat $350 estimate to cover title work, registration, and dealer documentation, and finances the remaining balance over the chosen loan term. Minnesota permits a trade-in allowance against the taxable purchase price on a dealer sale, which this calculator does not apply, so the tax figure shown here should be treated as an upper bound for buyers who have a trade-in to offer.

1. Motor Vehicle Sales Tax. salesTax = vehiclePrice × 0.06875.
2. Total vehicle cost. The price, the tax, and a flat $350 title/registration/documentation estimate are summed.
3. Amount financed. The down payment (including any trade-in value entered) is subtracted from the total vehicle cost.
4. Amortization. The financed balance is amortized monthly at the entered APR over the chosen term:

$$M = P \times \frac{r(1+r)^n}{(1+r)^n - 1}$$

where $P$ is the financed amount, $r$ is the monthly interest rate, and $n$ is the term in months.

Using the calculator's default inputs:

• Vehicle price: $35,000.00
• Down payment / trade-in: $5,000.00
• Loan term: 60 months
• APR: 7.25%

Step 1: Motor Vehicle Sales Tax. $35,000.00 × 6.875% = $2,406.25.

Step 2: Total vehicle cost. $35,000.00 + $2,406.25 (tax) + $350.00 (title, registration, and doc fees) = $37,756.25.

Step 3: Amount financed. $37,756.25 minus $5,000.00 down = $32,756.25.

Step 4: Amortization at 7.25% APR over 60 months. The monthly rate is 7.25% ÷ 12 = 0.6041667%. Financing $32,756.25 at that rate over 60 months produces a monthly payment of approximately $652.48, with total interest of roughly $6,393 over the loan's life.

• The Minnesota trade-in allowance. Minnesota dealers can reduce the taxable purchase price by the value of a trade-in vehicle on a like-kind exchange, lowering the sales tax collected. This calculator taxes the full purchase price regardless of trade-in and treats the trade-in value only as a reduction to the amount financed.
• Value-based annual registration tax. Minnesota's yearly vehicle registration (tab) fee includes a component based on the vehicle's original MSRP that declines with age, meaning the true first-year and ongoing annual registration cost for a new $35,000 vehicle will likely exceed the flat $350 estimate this calculator allots across title, registration, and documentation combined.
• Lender fees and add-on products. Extended warranties, GAP insurance, and bank origination fees are excluded from the fee estimate.
• Credit-based rate variation. The APR a buyer actually qualifies for depends on credit history and the lender, which the calculator does not adjust for.
• Local wheelage taxes. Several Minnesota counties impose an additional wheelage tax collected alongside vehicle registration, which this calculator does not include.

• Confusing the 6.875% Motor Vehicle Sales Tax with the general 6.875% sales tax rate as if they were unrelated. They are the same combined rate; Minnesota's vehicle tax mirrors the general state sales tax rate exactly, which is a useful shortcut when estimating either.
• Not asking the dealer to show the taxable price after a trade-in allowance. Buyers with a trade-in should confirm the actual taxable base with the dealer since the true tax owed is often lower than a flat calculation on the full price suggests.
• Underestimating ongoing registration costs on a newer vehicle. Minnesota's MSRP-based registration tax component starts higher for newer vehicles and phases down over time, so the annual tab renewal in year one is typically the most expensive it will be.
• Forgetting county wheelage taxes exist. Depending on where the vehicle is registered, an additional local wheelage tax may apply on top of the state registration tax.
• Stretching the loan term to lower the payment without checking total interest. Extending from 60 to 72 or 84 months lowers the monthly figure the calculator's scenario toggles show but increases the total interest paid over the life of the loan.
