How to calculate a cost price (and markup)
Retailers and small sellers often search how to calculate a cost price when they know the shelf price and the markup they need, or the other way around. Markup is profit as a percentage of cost; margin is profit as a percentage of selling price — they are not the same.
Cost from retail and markup: Cost = Retail ÷ (1 + markup%). Example: sell at $80 with a 60% markup on cost → Cost = 80 ÷ 1.60 = $50. Wholesale vs retail is simply that relationship: your wholesale/cost sits under the retail price by your chosen markup.
Sale discounts use the same percentage tools: Sale = Original × (1 − discount%). A 25% off $80 ticket is $60. Stacked discounts apply one after another on the reduced price — not added as a single percentage. Use the modes above to solve for original price, discount %, or dollars saved.

Frequently Asked Questions
How do I calculate multiple discounts?
Multiple discounts are applied sequentially, not added together. For example, 20% off then 10% off the reduced price gives you 28% total savings, not 30%. Apply the first discount, then calculate the second discount on the new price.
What's the difference between discount amount and percentage?
Discount amount is the fixed dollar amount you save (e.g., $10 off), while discount percentage is the relative savings as a percentage of the original price (e.g., 20% off). The percentage helps compare discounts across different price points.
How do I find the original price from a sale price?
Use the "Find Original Price" calculation type. Enter the final price and discount percentage, and the calculator will determine what the original price was before the discount was applied.
Are there limits to discount percentages?
Discount percentages can theoretically go up to 100% (free item), but in practice, most discounts range from 5-50%. Very high discounts (80%+) are often clearance sales or promotional offers. Always verify the original price to ensure the discount is legitimate.
Discount, sale price and cost-price formulas
Retail discount math and cost-price markup use the same percentage relationships — whether you are checking a sale or setting a wholesale-to-retail price.
- Sale price = Original × (1 − discount%)
- Discount $ = Original − Sale
- Cost price from retail & markup: Cost = Retail ÷ (1 + markup%)
- Markup % = ((Retail − Cost) ÷ Cost) × 100
Worked example: how to calculate a cost price
- You want to sell at $80 with a 60% markup on cost.
- Cost = 80 ÷ 1.60 = $50.
- Gross profit = $30; markup on cost = 60%.
- For a 25% off sale on $80: sale = 80 × 0.75 = $60.
