A percent off discount removes part of the original price. Use this sale price calculator for retail markdowns, online coupon codes, Black Friday deals, clearance pricing, supplier quotes, and any promotion expressed as a percentage.
A Black Friday TV deal saves $279.65, bringing the sale price to $519.35 before tax.
Reverse the discount to find the jacket’s original price: $63 ÷ 0.70 = $90.
The grocery coupon saves $2.90, so the checkout price before tax is $11.60.
Half price means you save $60 and pay $60. A 50% discount always leaves 50% to pay.
The retail markdown saves $7.20 and reduces the lamp’s price to $40.80.
Stacked discounts on $100 produce a $72 price and a 28% effective discount, not 30%.
The item or service price before any coupon, promotion, or retail markdown is applied.
The share of the original price removed by the discount, expressed as a percentage.
The actual money saved: original price minus the sale price.
The discounted amount you pay before tax, shipping, fees, or other charges.
Multiply the original price by 0.80. For example, 20% off $50 is $50 × 0.80 = $40, so you save $10.
Thirty percent of $100 is $30. Subtract that saving from the original price, and the final sale price is $70.
Divide the sale price by the percentage that remains. If an item is $75 after 25% off, divide $75 by 0.75 to get the $100 original price.
Use (original price − sale price) ÷ original price × 100. If a $120 item sells for $90, the discount is 25%.
No. Each discount applies to the already-reduced price. A 20% discount followed by 10% off produces a 28% effective discount, because 0.80 × 0.90 = 0.72.
Discounts are usually applied before sales tax. The tax is then calculated on the discounted sale price. Store rules and local laws can vary.
Yes. A 50% discount removes half of the original price, so you pay the other half.
Compare the actual savings. Percent off is often more valuable on expensive items, while a fixed-dollar coupon may win on lower-priced purchases. Convert the percentage to money before choosing.
Yes. It works as a coupon savings calculator, clearance price calculator, retail markdown tool, and Black Friday discount calculator. Enable the additional discount option when coupons stack.
