Calculate the sale price after a discount, savings amount, or find what discount percentage was applied. Supports stacked discounts and bulk purchase savings.
How much will you save? What is the price after a 30% discount? What percentage discount turns $80 into $56? This calculator answers all discount-related questions instantly. Enter the original price and discount percentage to see the sale price and savings — or enter the original and sale price to find the discount percentage.
The calculator also handles stacked discounts (a second percentage off the already-discounted price), which is common during major sales events. Importantly, stacked discounts do NOT add together: a 20% discount followed by a 10% discount is not 30% off — it is 28% off the original price.

Sales and promotions are everywhere, but not every "deal" is a good deal. This calculator lets you cut through marketing noise and see the actual savings in dollars and percentages. It helps you compare different offers — is 25% off $120 better or worse than a flat $25 off?
For business owners, it shows the exact revenue impact of a discount. A 20% price cut requires a 25% increase in unit sales just to maintain the same revenue — and even more to maintain profit. Understanding these numbers prevents costly pricing mistakes.
Discounted Price = Original Price × (1 − Discount% / 100) Savings = Original Price − Discounted Price Discount% = ((Original − Sale) / Original) × 100 Stacked Discounts: Price after both = Original × (1 − Disc1%) × (1 − Disc2%) Effective Discount = 1 − (1 − Disc1%)(1 − Disc2%)
Result: Sale Price: $90.00 | You Save: $30.00
A $120 item at 25% off: $120 × 0.75 = $90. You save $30. If a second 10% discount is stacked: $90 × 0.90 = $81. Total savings: $39 (effective 32.5% off, not 35%).
Research shows that consumers respond more strongly to percentage discounts on cheap items ($10 shirt marked 30% off) and dollar discounts on expensive items ($200 off a $2000 laptop). This is called the "Rule of 100" — use percentage for items under $100 and dollar amounts for items above $100. Marketers exploit this, but as a consumer, you should always calculate the actual dollar savings.
A common mistake is thinking a 20% discount only requires 20% more sales to break even. In reality, the math is much worse. If your margin is 40% and you offer a 20% discount, you need to sell 100% more units just to maintain the same gross profit. This is why excessive discounting destroys businesses: the volume required to compensate rarely materializes.
Instead of blanket discounts, consider: tiered discounts (10% off $50+, 20% off $100+), loyalty rewards, bundling (discount when bought together), time-limited flash sales, and value-added offers (free shipping instead of price cuts). Each preserves more margin than a simple percentage off.
The first discount is applied to the original price. The second discount is applied to the new (already discounted) price — NOT the original. Example: $100 − 20% = $80. Then $80 − 10% = $72. Effective discount: 28%, not 30%.
"Percent off" scales with price: 20% off $50 saves $10, 20% off $500 saves $100. "Dollars off" is fixed. For cheap items, a flat dollar discount is often better. For expensive items, a percentage is usually more valuable.
Discount % = ((Original Price − Sale Price) / Original Price) × 100. Example: Was $80, now $56. Discount = ($80 − $56) / $80 × 100 = 30% off.
Not necessarily. A 50% discount on an overpriced item may still be more expensive than a competitor with no discount. Always compare the final out-of-pocket price, not just the discount percentage.
Buy One Get One Free (BOGO) is effectively 50% off when you buy exactly 2 and need both. But if you only needed one, you are spending more than a 25% discount on a single item. Evaluate whether you actually need the extra quantity.
Discount to clear seasonal/excess inventory, acquire new customers (introductory pricing), or match competitor promotions. Avoid discounting as your primary sales strategy — it trains customers to wait for sales and erodes brand value.
