Oklahoma City stacks the state’s 4.5% sales tax with a municipal rate of about 4.125%, giving a combined rate near 8.625% on most purchases. This calculator applies that rate to any amount, splits the result into its state and city portions, and lets you zero out the tax for exempt items like prescription drugs.

How it works

Sales tax in OKC is a straightforward percentage of the taxable amount, but the combined rate is the sum of two layers:

combined rate = state 4.5% + city 4.125% = 8.625%

taxable = exempt ? 0 : purchase amount
tax     = taxable × (rate / 100)
total   = purchase amount + tax

The tool also reports how much of the tax goes to the state versus the city, which is useful for budgeting and for understanding where the money lands.

Example

On a $100 purchase at the default 8.625% rate, the tax is $8.63 — about $4.50 to the state and $4.13 to the city — for a total of $108.63. Toggle the exemption on for a prescription and the tax drops to zero.

Notes

Special districts within Oklahoma City can add a small fraction of a percent, so if your receipt differs, edit the rate field to match. Unlike many states, Oklahoma taxes groceries, so do not expect a food exemption here.
