How to Calculate Markup: A Clear Step-by-Step Guide
Calculating markup is a short sequence of arithmetic once cost and the desired percentage are known. This page walks through the process so you can compute selling price (or reverse-engineer the percentage) with confidence.
You can follow the steps manually or use the free Discount & Markup Calculator to obtain the results instantly.
Step 1 – Determine Cost
Use the true product cost (purchase cost or fully loaded COGS). Exclude operating expenses; those are covered by the resulting margin rather than by inflating the product-cost markup.
Step 2 – Choose the Desired Markup Percentage
This may come from a target margin (converted with Markup = Margin ÷ (1 − Margin)), from category convention, or from competitive analysis. See the markup vs margin page for the conversion.
Step 3 – Calculate Markup Amount
Step 4 – Calculate Selling Price
Step 5 – Verify with Margin (Recommended)
Convert the markup to margin and confirm the residual percentage meets your target. The profit margin calculator and the main tool both support this check. A full margin walkthrough is on the how to calculate profit margin page.
Worked Example
Cost $40, desired markup 75 % → Markup amount $30 → Selling price $70.
Resulting margin = 30 ÷ 70 ≈ 42.9 %.
If the target had been a 40 % margin, the required markup would be 40 % ÷ 60 % ≈ 66.7 %, producing a selling price of approximately $66.67.

Frequently Asked Questions
How do I calculate markup step by step?
1. Determine the cost. 2. Choose the desired markup percentage. 3. Calculate markup amount = Cost × Markup %. 4. Add markup amount to cost to obtain selling price. 5. Optionally convert to margin for validation.
What is the markup formula?
Selling Price = Cost × (1 + Markup %). Markup Amount = Cost × Markup %.
How do I find the markup percentage if I know cost and price?
Markup % = (Selling Price − Cost) ÷ Cost × 100.
Should I convert markup to margin?
Yes, especially when comparing against financial targets or industry margins. Use Margin = Markup ÷ (1 + Markup).
Can the calculator do these steps for me?
Yes. The Discount & Markup Calculator accepts cost and markup percentage (or cost and selling price) and returns the missing values.
What is the most common mistake?
Treating a markup percentage as if it were a margin percentage, which understates the true residual profit.
