A discount calculator computes sale price and dollar savings from an original price and a percent or fixed discount—and can reverse-calculate the original price from a sale tag.
Stacked promos and bundle discounts may have restrictions — always verify final price at checkout.
A discount reduces the price you pay. Enter an original price and either a percentage off (e.g. 25%) or a fixed dollar amount off to see the sale price and how much you save.
Core formulas:
Stacked discounts are not additive: 20% off then 10% off the reduced price is 28% total off the original, not 30%. Calculations run in your browser—prices are not uploaded to servers.
Percent-off and fixed-amount discounts both work; stacked promos need step-by-step math, not added percentages.
Supports percent-off, fixed-amount-off, and reverse original-price mode using standard retail arithmetic.
Formula
Savings = original × (discount% ÷ 100) or fixed $
Sale price = original − savings
Original (reverse) = sale ÷ (1 − discount% ÷ 100)Type the full price before any discount (numbers only—no currency symbol in the field).
Select percentage off or a fixed dollar amount off, then enter the value.
Click Calculate to see final price, amount saved, and effective percent off.
If you know sale price and discount %, use reverse mode: original = sale ÷ (1 − discount%).
Input
Original: $79.99 · Discount: 30%Output
Sale price: $55.99 · You save: $24.00$79.99 × 0.30 = $24.00 savings; final price $55.99.
Input
Original: $120 · Sale price: $89Output
Discount: 25.8% off · You save: $31.00($120 − $89) ÷ $120 = 25.8% when the tag shows only dollar prices.
Input
Original: $200 · 20% then 15% on reduced priceOutput
Final: $136 · 32% off original (not 35%)$200 × 0.8 = $160, then $160 × 0.85 = $136.

Sale price = original × (1 − discount%). For 25% off $80: $80 × 0.75 = $60. Savings = $80 × 0.25 = $20.
Original = sale price ÷ (1 − discount%). $60 after 25% off: $60 ÷ 0.75 = $80.
No. 20% then 10% on the reduced price equals 28% total off the original, not 30%.
Discount% = ((original − sale) ÷ original) × 100. $120 down to $90 is 25% off.
Yes. Switch to fixed amount mode and enter dollars off—the tool computes final price and savings.
Multiply the original price by 0.70 (keeping 70% of the price). Example: 30% off $50 = $50 × 0.70 = $35. Or: savings = $50 × 0.30 = $15; final price = $50 − $15 = $35.
15–20% is a moderate discount common in retail sales. 25–30% is a strong deal. 50%+ is a clearance or deep discount. Compare to historical pricing (check CamelCamelCamel for Amazon) — retailers sometimes inflate original prices before 'discounting.'
Discount% = ((original − sale price) ÷ original) × 100. Example: was $120, now $84 → (($120 − $84) ÷ $120) × 100 = 30%.
BOGO 50% off on equal items is effectively 25% off both items combined. BOGO free on two identical items is 50% off each. Use the calculator: enter the cost of two units as the original price, and enter the value of one unit as the savings.
Sometimes. When they do, apply them sequentially: 20% sale first, then 10% coupon on the discounted price. This gives 28% total off (not 30%). The tool's stacked discount mode handles this correctly.
