What does the Triple Discount Calculator do?
A triple discount applies three discounts one after another, such as a sale price, a coupon and a loyalty reward. Each discount applies to the price left by the one before it, so the real total is less than the three percentages added up. Enter a price and the three discounts to see the final price, the effective discount and, with your product cost, your profit.
1. How to use this triple discount calculator?
- 1Enter the original price and the three discount percentages.
- 2Optionally add your product cost to see your profit and margin.
- 3Read the final price and the real total discount, and check the profit stays above zero.
What each input means
- Original price
- before discounts
- First discount
- % off
- Second discount
- % off the reduced price
- Third discount
- % off the reduced price
- Product cost (optional)
- for margin and limits
2. How is the triple discount calculator calculated?
- Final price = price × (1 − d1) × (1 − d2) × (1 − d3)
- Total discount % = 1 − (1 − d1) × (1 − d2) × (1 − d3)
- Profit = final price − product cost
- Highest third discount before a loss = 1 − cost ÷ price after two discounts
A $150 product at 20%, then 10%, then 5% off falls to $120.00, then $108.00, then $102.60. The real total discount is 31.6% (not 35%), saving $47.40. With a $60 product cost, profit is $42.60, a 41.5% margin, and the third discount could go up to 44.4% before a loss.
3. Who should use this tool?
- Stores combining a sale, a discount code and a loyalty or email offer.
- Owners checking that stacked promotions never sell below cost.
- Shoppers and marketers who want the real price after several discounts.

Why is three discounts of 20% not 60% off?
Because each one applies to the price after the last. Three 20% discounts take 48.8% off in total.
Should I let customers stack three discounts?
Only if the final price still leaves a margin you are happy with. Use your product cost here to check, and limit stacking in your discount settings.
How do I limit stacking in Shopify?
Shopify lets you choose which discount types can combine on each discount. Review the combination settings before you launch a promotion.
Is the final price the same in any order?
Yes. Multiplication does not depend on order, so the final price is the same whichever discount is applied first.
