A flat discount removes a fixed amount from the price, while a percentage discount removes a percentage of the original price. The better discount depends on the original price and the size of the saving.

What Is a Flat Discount?
A flat discount removes a fixed money amount from the original price.
For example, 20 off means the price is reduced by 20, no matter what the original price is.
If the original price is 100, a flat 20 discount gives a sale price of 80.
What Is a Percentage Discount?
A percentage discount removes a percentage of the original price.
For example, 20% off means 20 out of every 100 is removed from the original price.
If the original price is 100, 20% off also gives a discount amount of 20 and a sale price of 80.
Why the Difference Matters
Flat discounts and percentage discounts can produce very different savings when the original price changes.
A flat 20 discount always saves 20. A 20% discount saves more money as the original price increases.
That is why a percentage discount can be better on higher-priced items.
Example: Low Price Item
Suppose an item costs 50. A flat 15 discount saves 15 and gives a sale price of 35.
A 20% discount on 50 saves 10 and gives a sale price of 40.
In this case, the flat discount saves more money.
Example: High Price Item
Suppose an item costs 300. A flat 15 discount still saves only 15.
A 20% discount on 300 saves 60.
In this case, the percentage discount saves more money.
How to Compare Flat and Percentage Discounts
First, calculate the actual money saved from each offer.
Then compare the final sale price after each discount.
The lower final price is usually the better deal, unless other conditions such as shipping, minimum order value, or product quality matter.
Flat Discount Formula
For a flat discount, the formula is: sale price = original price - flat discount amount.
If the original price is 90 and the flat discount is 25, the sale price is 65.
This is simpler than a percentage discount because the saving amount is already known.
Percentage Discount Formula
For a percentage discount, first calculate the discount amount: original price × discount percentage ÷ 100.
Then subtract the discount amount from the original price.

Business Impact
For businesses, flat discounts can be easier for customers to understand, while percentage discounts can feel more attractive on larger prices.
Both can reduce profit margin if costs stay the same.

Conclusion
A flat discount removes a fixed amount. A percentage discount removes a percentage of the original price.
To compare them correctly, calculate the actual saving and final sale price for each offer.
