Smart Shopping Tips
🧮 How Discounts Work
A percentage discount is calculated by multiplying the original price by the discount rate, then subtracting that amount. For example, 25% off $100 = $100 – $25 = $75 final price.
Some stores use “percent off” while others show “sale price” — this calculator helps you verify either way.
🛒 US Sale Seasons

💡 Stacking Discounts
Use the “2nd Discount” field above to calculate stacked coupons. A 30% sale + extra 15% off doesn’t equal 45% — it’s 30% off first, then 15% off the reduced price, totaling 40.5% effective savings.
Example: $100 at 30% off = $70, then 15% off $70 = $59.50. Always check for promo codes before checkout. Browser extensions like Honey and Rakuten can find codes automatically.
⚠️ Watch Out For
This calculator shows the price before sales tax. In most US states, you’ll pay 4-10% tax on top of the discounted price at checkout.
Beware of “up to X% off” marketing — only select items may have the advertised discount. Verify each item’s actual discount.
Frequently Asked Questions
What is 30 percent off $80?
Thirty percent off $80 saves you $24, leaving a final price of $56. Enter $80 as the original price and select or type 30% in the discount field. If your state charges sales tax, add the rate to see the after-tax total as well.
How do I calculate stacked discounts like 20% off then an extra 15% coupon?
Stacked discounts do not simply add together. A 20% discount on $100 gives $80, then a 15% coupon off $80 gives $68 — an effective savings of 32%, not 35%. Use the second discount field in the calculator to handle stacked coupons automatically and see the true effective savings percentage.
Does the discount calculator include sales tax?
Yes. Enter your local sales tax rate in the optional Sales Tax field. The result will show both the pre-tax sale price and the total after tax. US states charge between 0% and 10.25% sales tax, so the after-tax amount can differ meaningfully from the advertised sale price.
How do Black Friday discounts work and how can I verify them?
Black Friday deals advertise a percentage off the ‘original’ price, but that original price is sometimes inflated. Enter the sale price and work backward, or compare the discounted price to prices from other retailers. The calculator’s price comparison bar shows exactly how much of the original you are still paying.
How do I calculate what percentage off a price is?
If an item is $60 and the original was $80, the savings are $20. Divide $20 by $80 and multiply by 100 to get 25% off. The calculator displays the effective discount percentage automatically when you enter both the original price and the discount rate, including when two discounts are stacked.
