The Profit Percentage Formula
The profit percentage formula calculates what portion of a sale is profit. There are two common formulas depending on whether you want to express profit relative to selling price (margin) or relative to cost (markup). Both are essential for pricing, financial analysis, and business planning.
Understanding these formulas empowers business owners to price products correctly, evaluate profitability, and make data-driven decisions. This guide walks through each formula step by step with real examples.
Essential Profit Percentage Formulas
Profit Margin Formula
Profit Margin (%) = ((Selling Price - Cost) / Selling Price) × 100
Where:
Selling Price = Revenue per unit
Cost = Total cost per unit
Markup Formula
Markup (%) = ((Selling Price - Cost) / Cost) × 100
Where:
Selling Price = Revenue per unit
Cost = Total cost per unit
Selling Price from Target Margin
Selling Price = Cost / (1 - Margin / 100)
Where:
Cost = Per-unit cost
Margin = Target profit margin percentage
Maximum Cost from Target Margin
Max Cost = Selling Price × (1 - Margin / 100)
Where:
Selling Price = Known or fixed selling price
Margin = Required minimum profit margin
Profit Percentage Formula in Action
Given
Cost
$60
Selling Price
$95
Calculation Steps
- 1Profit = $95 - $60 = $35
- 2Profit Margin = ($35 / $95) × 100 = 36.8%
- 3Markup = ($35 / $60) × 100 = 58.3%
- 4Price for 40% margin = $60 / (1 - 0.40) = $100
- 5Max cost at 40% margin and $95 price = $95 × 0.60 = $57
Result
At $95 selling price and $60 cost, profit margin is 36.8% and markup is 58.3%. To achieve 40% margin, you would need to charge $100 or reduce cost to $57.
All Profit Percentage Formulas in One Table
| What You Want | Formula | Example ($60 cost, $95 price) |
|---|---|---|
| Profit Margin % | (Price - Cost) / Price × 100 | 36.8% |
| Markup % | (Price - Cost) / Cost × 100 | 58.3% |
| Price from margin | Cost / (1 - Margin) | $100 (at 40%) |
| Price from markup | Cost × (1 + Markup) | $96 (at 60%) |
| Margin from markup | Markup / (1 + Markup) | 36.8% |
| Markup from margin | Margin / (1 - Margin) | 58.3% |
Step-by-Step Profit Percentage Calculation
1
Identify Your Numbers
Determine your total cost (including all direct costs) and your selling price. If calculating for multiple products, do this per-product.
2
Calculate Dollar Profit
Subtract cost from selling price: $95 - $60 = $35 profit per unit.
3
Choose Your Base
For margin, divide by selling price. For markup, divide by cost. Margin is standard for financial reporting; markup is common for pricing.
4
Apply the Formula
Margin: $35 / $95 × 100 = 36.8%. Markup: $35 / $60 × 100 = 58.3%. Both represent the same $35 profit.
5
Verify and Compare
Check your result against industry benchmarks. Calculate the price needed for your target margin and compare to competitive pricing.
- The profit margin formula always gives a lower percentage than the markup formula for the same transaction
- Margin can never exceed 100%; markup can be any positive number
- At 50% margin, markup is 100% (you are doubling your cost)
- At 100% markup, margin is 50% (half of revenue is profit)
- For quick estimation: margin ≈ markup × 0.6 to 0.7 (depending on the level)
i
When to Use Which Formula
Use margin for: financial statements, investor presentations, comparing to industry benchmarks, break-even analysis. Use markup for: setting prices from known costs, supplier negotiations, quick mental math on pricing.
