Frequently Asked Questions
How do I calculate a discount percentage?
To find the discount percentage: ((Original Price - Sale Price) / Original Price) × 100. For example, if an item was $100 and is now $75, the discount is ((100-75)/100) × 100 = 25%.
How do I find the original price before a discount?
Original Price = Sale Price / (1 - Discount/100). For example, if an item costs $80 after a 20% discount: $80 / (1 - 0.20) = $80 / 0.80 = $100 original price.
What is the difference between markup and margin?
Markup is the percentage added to the cost to get the selling price (based on cost). Margin is the percentage of the selling price that is profit (based on selling price). A 50% markup equals about 33% margin.
How do I calculate the final price after multiple discounts?
Apply discounts sequentially. For example, 20% off then 10% off: First apply 20% ($100 × 0.80 = $80), then apply 10% to the result ($80 × 0.90 = $72). Note: This is NOT the same as a 30% discount.
How do I calculate markup on cost?
Markup Amount = Cost × (Markup Percentage / 100). Selling Price = Cost + Markup Amount. For example, with a $50 cost and 40% markup: $50 × 0.40 = $20 markup, so selling price is $70.
