Ohio Sales Tax Calculator — Subtotal, Tax, and Total

Quick, accurate sales tax math for Ohio purchases. Enter price, quantity, and pick a county rate to see subtotal, tax, and total.

Quick Start

Enter item price (USD) and quantity (whole units).
Select the county’s combined rate (state + local).
View subtotal, sales tax, and total due.

Note: Ohio’s state base rate is 5.75%. Counties may add local tax.

How It Works / Inputs → Outputs

Inputs

Item price (USD per unit)
Quantity (units; minimum 1, whole numbers)
County rate (decimal; e.g., 0.0725 = 7.25%)

Outputs

Subtotal = price × quantity
Sales tax = subtotal × county rate
Total = subtotal + sales tax

Formula / Method

rate = countyRate
subtotal = price × quantity
salesTax = subtotal × rate
total = subtotal + salesTax

Variables: countyRate (decimal), price (USD/unit), quantity (units).

Worked Example

Scenario: Price $100.00, Quantity 2, County rate 0.0725 (7.25%).

Subtotal = 100 × 2 = $200.00
Sales tax = 200 × 0.0725 = $14.50
Total = 200 + 14.50 = $214.50

Result: Subtotal $200.00; Tax $14.50; Total $214.50.

Applications / Use Cases

Point-of-sale checks for retailers.
Online checkout estimates for Ohio customers.
Budgeting larger purchases across counties.

Assumptions & Limitations

Uses a single combined county rate you select.
Does not handle exemptions, caps, or special districts.
Rounding: display is currency rounded to cents; internal math is straightforward multiplication.

Tips / Common Mistakes

Pick the correct county where the sale is sourced or delivered.
Enter rate as a decimal in formulas (0.0725, not 7.25).
Quantity must be whole units; fractional quantities require item price adjustment.

Inputs & Units

price: USD per unit
quantity: units (integer ≥ 1)
countyRate: decimal (e.g., 0.0675)

Scenario Variations

Base rate only: use 0.0575 if no county add-on applies.
Different counties: swap to the matching combined rate (e.g., 0.0675 for 6.75%).
