Columbus vs the Ohio average
The average combined rate across Ohio is about 7.24%, so Columbus at 7.5% is above the state norm by roughly 0.26 percentage points. On a $30,000 car (where vehicle tax rules allow the general rate), that gap alone is about $78 — one reason big purchases are planned around exact addresses, not state averages.

What this means in Columbus
The rate bites hardest on large, planned purchases. At 7.5%, a $10,000 purchase carries $750.00 of tax — $26.00 more than the same purchase at the Ohio average rate of 7.24%, and $89.00 more than at the all-state average of 6.61%. On everyday spending the difference is cents; on vehicles, appliances and furniture it decides where people choose to buy.
Day-to-day, the grocery exemption keeps the weekly food shop outside this rate in Ohio — the 7.5% applies to general merchandise, electronics and prepared food. Budget the rate into non-food spending, not the food bill.
