Reverse Markup Calculator
When businesses price products, they typically start with the cost price and apply a markup to set the selling price. But what if you only know the selling price and the markup percentage? That’s where the Reverse Markup Calculator comes in.
This tool helps you quickly calculate the original cost price when you know the selling price and markup. It’s especially useful for retailers, wholesalers, accountants, and anyone reviewing supplier pricing.
What Is Reverse Markup?
Reverse markup is the process of working backward from a product’s selling price and markup percentage to determine its original cost price.
For example:
- If an item sells for $120 with a 50% markup, the cost price wasn’t $60 (that would be margin-based math). Instead, the Reverse Markup Calculator finds the correct original cost as $80.
Formula for Reverse Markup
The formulas are:
- Selling Price from Markup:
Selling Price=Cost Price×(1+Markup %100)\text{Selling Price} = \text{Cost Price} \times \left(1 + \frac{\text{Markup \%}}{100}\right)Selling Price=Cost Price×(1+100Markup %)
- Reverse Formula (to find Cost Price):
Cost Price=Selling Price1+Markup %100\text{Cost Price} = \frac{\text{Selling Price}}{1 + \frac{\text{Markup \%}}{100}}Cost Price=1+100Markup %Selling Price
Example Calculations
Example 1 – Retail Item
- Selling Price = $120
- Markup = 50%
- Cost Price = 1201.50=80\frac{120}{1.50} = 801.50120=80
✅ The item originally cost $80.
Example 2 – Electronics
- Selling Price = $250
- Markup = 25%
- Cost Price = 2501.25=200\frac{250}{1.25} = 2001.25250=200
✅ The supplier’s cost was $200.
Example 3 – Wholesale Order
- Selling Price = $18
- Markup = 80%
- Cost Price = 181.80=10\frac{18}{1.80} = 101.8018=10
✅ The cost per unit was $10.
