Discount estimate note
Final checkout totals can differ because of coupons, shipping rules, taxes, rounding, and store-specific pricing. Review the actual checkout before purchase decisions.
A discount calculator subtracts the percent-off amount from the original price.
For example, 20% off $80 saves $16 and makes the sale price $64 before tax.
Use pre-discount price
Enter the sticker price before coupons, loyalty credits, shipping, or fees.
Separate tax from savings
Use the tax field only when you need an estimated checkout total after the discount.
Example
A 25% discount on $120 saves $30 and creates a $90 sale price before tax.
Assumption
Tax is applied after the discount, which is common for many retail calculations.
Limitation
Actual checkout totals can vary because of local tax rules, fees, shipping, coupons, or rounding.
