How it works
The Discount Calculator computes final purchase prices, total savings, and effective percentage off after single or stacked store discounts.
Supports secondary coupon codes (for example, take an additional 20% off already marked-down clearance items).
Calculates local sales tax on the discounted subtotal so you know the exact final checkout amount.
Great for Black Friday, seasonal clearance sales, and coupon shopping.
Frequently asked questions
- How do stacked discounts (e.g. 50% + extra 20%) work?
- Stacked discounts are applied sequentially, not added together. A $100 item at 50% off is $50. An extra 20% off $50 takes off $10, leaving $40 (an effective 60% total discount, not 70%).
- Is sales tax applied before or after the discount?
- In most jurisdictions, sales tax is applied to the final discounted purchase price rather than the original manufacturer suggested retail price (MSRP).
- How do I calculate what percentage off a sale is?
- Divide the dollar discount amount by the original price and multiply by 100.
