What the numbers mean
Local taxes contribute at least as much as the state rate to the average total. Use a supported city page or the exact percentage printed on the receipt; using only 4.5% would materially overstate the pre-tax price.
Oklahoma ranks #6 nationally by average combined rate. The 3 city calculators below show how the local portion changes the math.

|---|---|---|---|
| $50.00 | 9.06% | $45.85 | $4.15 |
| $100.00 | 9.06% | $91.69 | $8.31 |
| $250.00 | 9.06% | $229.23 | $20.77 |
| $500.00 | 9.06% | $458.46 | $41.54 |
