❓ Frequently Asked Questions
How do double discounts work?
Double discounts are usually calculated sequentially, not additively. For example, '50% off + extra 20% off' means you take 50% off the original price, and then 20% off the *new* price. The total discount is 60%, not 70%.
Is sales tax calculated before or after the discount?
Sales tax is almost always calculated on the *final discounted price*, not the original price. This saves you money on tax as well!
What is the formula for discount?
The formula is: Discount Amount = Original Price x (Discount % / 100). Final Price = Original Price - Discount Amount.
How do I calculate 'Buy One Get One Free'?
Buy One Get One Free (BOGO) is effectively a 50% discount if you buy two items of the same price. If the items have different prices, the discount is usually applied to the cheaper item.
Can I stack multiple coupons?
It depends on the store's policy. Our calculator allows you to enter an 'Extra Discount' to simulate stacking a store sale with a coupon code.
How do stacked discounts work?
Discounts apply sequentially (e.g., 50% off, then 20% off the reduced price). Our calculator models this correctly.
Can I include tax?
Yes. Enter your local tax percent to estimate the final checkout total.
