Fill in any two fields to find your sale price, savings, or original price
💡 Why This Matters Quickly see what you'll actually pay before checkout, or check whether a "sale" is really the deal it claims. Fill in any two of the three fields and this tool solves the third — it even handles price increases if you enter a negative percentage.
Stacked discounts don't add — they multiply. "20% off, then an extra 10% at checkout" isn't 30% off; it's 100 × 0.80 × 0.90 = 72% of the price, an effective discount of 28%, not 30%.

Percent off is a percentage-decrease calculation: savings = original price × (percent off ÷ 100), and sale price = original price − savings. Enter a negative percentage and the same formula flips into a percentage increase instead — useful for modeling a price hike rather than a discount.
"Percent off" and "discount" are exactly the same thing — just different words for the same math. The bigger the percentage, the more you save, but remember that percentages of a bigger original price produce bigger dollar savings even at the same rate.
This calculator applies one flat percentage. It does not chain multiple discounts together — stacked discounts multiply rather than add, so "20% off, then an extra 10%" is not the same as 30% off. Use the Double Discount or Triple Discount calculators for stacked deals, and this tool shows pre-tax pricing.
Compare the sale price against other stores or past prices to judge whether a deal is genuinely good. If you're comparing a percentage discount to a flat dollar-amount discount, run both through this calculator — the bigger raw discount doesn't always come from the bigger-looking percentage.
Example: A store has everything 75% off, and a TV originally cost $5,000. Savings = $5,000 × 0.75 = $3,750. Sale price = $5,000 − $3,750 = $1,250. To model a price increase instead — say a 10% price hike on a $100 item — just enter -10 in the percent off field: the calculator returns $110.
Savings = original price × (percent off ÷ 100). Sale price = original price − savings, which is the same as original price × (1 − percent off ÷ 100).
Yes — "percent off" and "discount" describe the exact same calculation. They're used interchangeably in retail and everyday conversation.
Yes — enter a negative number in the percent off field (like -10 for a 10% increase) and the calculator will apply the percentage increase formula instead of a discount.
