Calculates the final price after applying a percentage discount, with an optional tax applied after the discount.
Discounted Price = Original × (1 − Discount / 100) Final Price = Discounted × (1 + Tax / 100) Savings = Original − Discounted
100 × (1 − 0.20) = 80. You save $20.

Multiply $100 by (1 − 0.20) = 0.80. The sale price is $80, saving you $20.
First apply the discount to get the discounted price, then multiply by (1 + tax rate/100) to get the final price.
Percent-off scales with price (20% off $200 is $40). Fixed-amount-off removes the same dollars regardless of ticket size ($20 off is a bigger relative win on a $50 item than on a $500 item).
Retailers apply rules in different orders. Some stack multiplicatively, some disallow stacking, and some apply employee discounts before public coupons. Read the fine print — this tool models a single headline discount.
It is the list-price difference before financing, shipping, or restocking fees. Your bank statement may still differ if tax is computed on pre-discount price in your jurisdiction.
