Ohio charges a statewide base sales tax rate of 5.75% as of 2025, one of the lower state base rates in the US. Counties and regional transit authorities add their own local rates on top, so the combined rate you actually pay at the register usually lands between 6.5% and 8%. This calculator lets you add tax to a pre-tax price or strip it back out of a tax-inclusive total.
How it works
The calculator uses two simple operations on the rate you set (5.75% by default):
- Add tax — multiply the pre-tax price by (1 + rate ÷ 100). At 5.75% that is
price × 1.0575. The tax amount alone isprice × 0.0575. - Remove tax — divide the tax-inclusive total by (1 + rate ÷ 100), i.e.
total ÷ 1.0575, to recover the pre-tax price. The difference is the tax that was included.
To match your exact location, replace 5.75% with your local combined rate.
Example
A $100 purchase at the 5.75% state base rate:
| Step | Calculation | Result |
|---|---|---|
| Tax amount | 100 × 0.0575 | $5.75 |
| Total (add tax) | 100 × 1.0575 | $105.75 |
| Pre-tax from $105.75 (remove tax) | 105.75 ÷ 1.0575 | $100.00 |
If your county brings the combined rate to 7.5%, the same $100 item totals $107.50. All calculations run entirely in your browser — no amounts or personal data are transmitted.
Important: Ohio’s state rate is 5.75%. Each county levies an additional 0.75–2.25%, so combined rates typically range from 6.5% to 8%. Food for home consumption is exempt.
