- Price before tax = 100
- Sales tax rate = 5.6
- Or a price that already includes tax = 107.25
- Quantity = 1
- Tax added = 100 * 5.6 / 100 = 5.6
- Total with tax = 100 + 5.6 = 105.6
- Total for the quantity = 105.6 * 1 = 105.6
- Price before tax, working backwards = 107.25 / (1 + 5.6/100) = 101.563
- Tax inside a tax-inclusive price = 107.25 - 101.563 = 5.6875
- Tax as a share of the total = 105.6 > 0 ? 5.6 / 105.6 * 100 : 0 = 5.303 03
- Multiply the net price by this = 1 + 5.6/100 = 1.056
Values are shown to six significant figures here; the arithmetic itself runs on exact fractions and is only rounded where a number is printed.

The formula
- tax = price x rate
- total = price x (1 + rate)
- to remove tax: net = gross / (1 + rate), never gross x (1 - rate)
Removing a tax is division, not subtraction. Taking 7.25% off a tax-inclusive price undercharges you every time.
Rates change and local additions vary by address. Treat the prefilled rate as a starting point and check the current combined rate for the exact jurisdiction.
