Frequently Asked Questions
How do I calculate a discount?
Multiply the original price by the discount percentage divided by 100 to get the discount amount. Subtract that from the original price to get the final price. For example, 25% off $100 saves you $25, leaving a final price of $75.
What is the difference between markup and margin?
Markup is the percentage added to the cost price to reach the selling price (based on cost). Margin is the profit as a percentage of the selling price. A 100% markup on a $50 item gives a $100 selling price and a 50% margin.
How do stacked discounts work?
Stacked discounts apply one after another. For example, 40% off then 15% off does not equal 55% off. A $100 item becomes $60 after 40% off, then $51 after an additional 15% off — a total saving of 49%.
How do I find the original price from a sale price?
Divide the sale price by (1 minus the discount percentage divided by 100). For example, if something costs $75 after a 25% discount, the original price was $75 / 0.75 = $100.
How do I calculate the selling price from a desired profit margin?
Divide the cost price by (1 minus the desired margin percentage divided by 100). For a 50% margin on a $50 cost, the selling price is $50 / 0.50 = $100.
What markup percentage gives a 50% profit margin?
A 100% markup gives a 50% margin. Markup and margin are related but different: 50% margin means profit is 50% of the selling price, which requires a 100% markup on the cost.
