Buying a car in Oklahoma
Every figure below is sourced to Oklahoma’s own revenue or motor vehicle publications and dated. Estimates only.
Auto loan calculator
The real out-the-door number — including whether your state credits your trade-in against the sales tax.
Auto lease calculator
Money factor, residual, and the payment — taxed by your state's actual method, since some states tax a lease's full value upfront instead of each payment.
Loan payoff calculator
What paying extra actually saves you — in interest and in months — on a car loan, a personal loan, or anything else that amortizes.
0% APR vs. cash rebate
Which dealer offer actually costs less over the life of the loan, and the rate at which they tie.
Personal loan calculator
Payment, total interest, and the effective APR once an origination fee is deducted from what actually reaches your account.
Debt consolidation calculator
Whether one loan actually beats paying your existing debts off as they are — measured against the best you could do without consolidating.
Auto refinance calculator
Whether refinancing your car loan is worth it — including whether a lower payment is being bought with a longer term on a depreciating asset.
Lease vs. buy a car
The same car both ways over the same months, with the resale value credited to the buyer — the part most comparisons leave out.

Local tax in Oklahoma
IMPORTANT — 4.5% is the SUM OF TWO SEPARATE STATE LEVIES, not a single rate found in any one statute: a 3.25% motor vehicle excise tax (68 O.S. 2103) plus a 1.25% state sales tax (68 O.S. 1355). NO LOCAL SALES TAX applies to the vehicle itself — 68 O.S. 2106 makes the excise tax 'in lieu of all other taxes on the transfer or the first registration in this state of vehicles', carving out only the 1.25% state levy plus registration, title and Corporation Commission fees. USED VEHICLES ARE NOT A FLAT RATE: the excise component is $20.00 on the first $1,500 of value plus 3.25% of the remainder, so a flat 4.5% overstates the tax on a low-value used car. The taxable value must fall within 20% of the average retail value in the guide the Tax Commission prescribes, or the Commission substitutes one.
