Tax is applied to the discounted price (a common method). If your store applies tax differently, results may vary slightly.
How it works
A percentage discount reduces the price; sales tax, if applied, is usually calculated on the discounted price.
Formula
- Savings = price × (discount% ÷ 100); Discounted = price − savings; Final = discounted + tax.
Worked example
$50 with 20% off and 8% tax: final $43.20.
