Example: If you paid 108 / 1.08 = $100 (original price).

FAQs
Q: Why use this instead of a regular tax calculator?
A: Regular calculators add tax to a price. This one removes tax to show the base price.
Q: What if I don’t know the tax rate?
A: Check your receipt or search “[Your State] sales tax rate.” Most states have 4–7% rates.
Key Terms
- Final Price: Amount you paid (tax included).

Notes
