How Oregon tax changes your car loan

On a $30,000 car, Oregon’s 0% tax adds $0 to the price. If you finance it, your payment rises from $594.04 to $594.04 a month over 60 months at 7%, and you pay an extra $0 in interest on the tax. Among the 21 states in our state tables, Oregon ranks 1 from lowest to highest base tax rate (1 is lowest).

$27,600 financed: payment by loan length

At 7% APR, financing $27,600 (the $30,000 price and $600 in fees minus $3,000 down) costs $546.51 a month over 60 months and $416.56 over 84 months. The longer loan lowers the payment by $129.95 but adds $2,200 in interest. Going the other way, 36 months raises the payment to $852.21 and cuts total interest to $3,079.

Oregon sales tax on a car purchase

Oregon has no general sales tax, but it charges a vehicle privilege tax on new cars and title and registration fees, so your out-the-door cost is still higher than the sticker price.

This calculator uses 0% as the starting tax rate, and you can change it to match your county. If you roll the tax into the loan, you pay interest on it too.

$30,000$0$30,600$605.92

$50,000$0$50,600$1,001.94

Paying extra

Adding $100 a month to this loan would pay it off 10 months sooner and save $957 in interest, as long as your lender applies extra money to principal and charges no prepayment penalty. Ask before you start.

Can you afford a $30,000 car?

A common rule of thumb, the 20/4/10 guideline, suggests 20% down, a term of at most 4 years and total car costs under 10% of gross income. On payment alone, $546.51 a month points to a gross income of roughly $65,600 a year to stay at 10%, before insurance, fuel and maintenance. This loan departs from the guideline because the down payment is 10% rather than 20% and the term of 60 months is longer than 48, so the payment is lower than a stricter plan would give but the loan costs more overall.

Will you owe more than the car is worth?

New cars commonly lose around 20% of their value in the first year and roughly 15% a year after that, though this varies by model. Using that rough rule on a $30,000 car, the car stays worth more than the loan from the end of the first year. Gap insurance can cover the difference if the car is totaled while you are underwater.
