What Is the Florida Sales Tax Calculator?
This calculator applies to purchases in Florida, United States. Florida charges a statewide base sales tax of 6%, and many counties add a discretionary surtax (commonly 0.5%–1.5%), so combined rates often range from 6% to 7.5%. Enter your pre-tax price and the rate that applies to your county to instantly see the tax amount and the total you'll pay.
How to Use It
Type the price of the item before tax, then enter the sales tax rate as a percentage. If you only pay the state rate, use 6. If your county adds a surtax, use the combined rate (for example, 7 for a county with a 1% surtax). The calculator returns the tax amount and the grand total.
The Formula Explained
The math is straightforward. First the percentage is converted to a decimal by dividing by 100. The tax is the price times that decimal rate, and the total is simply the price plus the tax:
$$\text{Tax} = \text{Price} \times \left(\frac{\text{Rate}}{100}\right)$$
$$\text{Total} = \text{Price} + \text{Tax} = \text{Price} \times \left(1 + \frac{\text{Rate}}{100}\right)$$
Worked Example
Suppose you buy an item for $100 in a county with a combined rate of 7%. The tax is $$100 \times 0.07 = \$7.00$$ and the total is $$100 + 7 = \$107.00$$
