Discount & Markup Calculator
Calculate markups, margins, discounts, and pricing in one versatile tool. Five calculation modes cover every common pricing scenario: markup from cost, profit margin analysis, discount from original price, reverse discount to find the original price, and stacked discounts for multiple sequential reductions. Includes a bulk pricing table, a clear margin vs markup explainer, and real-time results as you type.
如何使用
Select a calculation mode from the tabs. Enter any two known values and the calculator solves for all unknowns instantly. In Markup mode, enter cost and markup percentage to get the sale price. In Margin mode, enter cost and sale price to see the profit margin. Discount mode calculates savings from a percentage off, while Reverse Discount finds the original price. Stacked Discounts lets you apply multiple sequential discounts to see the true total reduction.

What is the difference between markup and margin?
Markup and margin both measure profit but use different denominators. Markup percentage is calculated as (profit divided by cost) times 100. Margin percentage is (profit divided by sale price) times 100. For example, if you buy an item for 60 and sell it for 100, your profit is 40. The markup is 40/60 = 66.7%, but the margin is 40/100 = 40%. Markup is always a higher percentage than margin for the same transaction. Retailers typically think in terms of margin, while manufacturers often use markup.

Why are stacked discounts not the same as adding the percentages together?
Each discount in a stack applies to the already-reduced price, not the original. A 20% discount followed by a 10% discount does not equal 30% off. Starting with 100, 20% off gives 80. Then 10% off 80 gives 72. The total reduction is 28%, not 30%. The order of stacked discounts does not matter mathematically, but the combined effect is always less than simply adding the percentages. This calculator shows you the exact final price and true total discount percentage.

How do I find the original price before a discount was applied?
Use the Reverse Discount mode. If you know the final price and the discount percentage, the original price equals the final price divided by (1 minus the discount percentage divided by 100). For example, if an item costs 72 after a 20% discount, the original price was 72 divided by 0.80, which equals 90. This is useful when you see a sale price and want to know what the item originally cost, or when verifying that a claimed discount is accurate.

What is a good profit margin for retail?
Healthy profit margins vary significantly by industry. Grocery stores typically operate on thin margins of 1-3%. Clothing retail averages 4-13%. Software and digital products can achieve 70-90% margins. Restaurants average 3-9%. The right margin depends on your volume, overhead costs, and competitive landscape. A high-volume low-margin business like a grocery store can be just as profitable as a low-volume high-margin boutique. This calculator helps you model different pricing scenarios to find the sweet spot.
