Frequently asked questions
How do I calculate the price after a discount?
Multiply the original price by (1 − discount/100). For 30% off $120: $120 × 0.70 = $84. Alternatively, calculate the discount amount ($120 × 0.30 = $36) and subtract it.
How do stacked discounts work (e.g. 20% + 10%)?
Apply them sequentially, not added. 20% then 10% is not 30% off. It is: price × 0.80 × 0.90 = 72% of original (28% total discount). Enter the combined effective discount in this calculator.
How do I find what discount I got?
Discount percent = (original − sale price) ÷ original × 100. If something was $80 and you paid $60: ($80 − $60) ÷ $80 × 100 = 25% off.
Does this include tax?
No. This calculates the pre-tax discounted price. Tax is typically applied after the discount, so your final amount is the discounted price plus tax. See the Sales Tax Calculator for that step.
Is a higher percentage always a better deal?
Not necessarily. A 50% discount on an inflated price may still cost more than 20% off a fairly priced item. Compare the actual final price, not just the percentage, and check if the 'original' price was genuine.
