Profit Margin Calculator – Margin, Markup, Cost and Price
The Profit Margin Calculator helps you understand exactly how profitable a product, service or project really is. Instead of guessing whether a price is “good enough,” you can see profit per unit, total profit, margin percentage, markup and the selling price required to hit your target margin. This is essential for ecommerce stores, service businesses, wholesalers and anyone who makes pricing decisions.
Small changes in cost or selling price can have a large impact on profit margin. Raising prices without understanding margin can lead to lost sales. Keeping prices too low can leave money on the table or even make profitable-looking products silently unprofitable. This calculator brings clarity so you can test multiple scenarios before committing to a price.
How the Profit Margin Calculator Works
The calculator is organized into three focused modes:
- Margin & Markup: Enter cost, selling price and quantity to see profit, margin, markup and totals.
- Price from Margin: Enter cost and desired margin to find the required selling price and implied markup.
- Cost from Margin: Enter selling price and target margin to find the maximum allowable cost and resulting profit.
In every mode, you can change numbers quickly and instantly see the effect on profit. This makes it easy to model price changes, supplier quotes, bulk discounts or promotional offers.
Key Definitions: Profit, Margin and Markup
To use the calculator effectively, it helps to distinguish between three related but different ideas:
- Cost: What it costs you to provide one unit (purchase cost, production cost or full unit cost).
- Selling Price (Revenue per Unit): What you charge the customer for one unit.
- Profit: The difference between selling price and cost.
Profit per Unit
Profit Margin (%)
Profit margin tells you what portion of each sales dollar you keep as profit after cost.
Markup (%)
Markup tells you how much higher your selling price is compared with your cost. For the same transaction, markup will always be numerically higher than margin because the denominator is smaller (cost vs revenue).
Mode 1: Margin & Markup from Cost and Price
In the first mode, you already know your cost and selling price. You might be checking a supplier quote, reviewing a current price list or analyzing a live product in your store. The calculator outputs:
- Profit per unit
- Total profit for the quantity entered
- Profit margin percentage
- Markup percentage
- Total revenue (selling price × quantity)
- Total cost (cost × quantity)
Example
Suppose your cost per unit is 50 and your selling price is 80. Profit per unit is 30. Profit margin is 30 ÷ 80 = 37.5%. Markup is 30 ÷ 50 = 60%. If you sell 100 units, total revenue is 8,000, total cost is 5,000 and total profit is 3,000.
Mode 2: Selling Price from Cost and Target Margin
The second mode is useful when you know your cost and you have a specific target margin you want to achieve. This is common when building price lists, launching new products or setting standard markup policies.
Formula for Selling Price from Margin
Starting from:
Rearranging for Price gives:
Here Margin is expressed as a decimal (for example, 40% becomes 0.40). If the target margin is 40% and cost is 50, you divide 50 by 0.6 to get a required price of 83.33. The calculator handles this automatically and also reports the implied markup and profit per unit.
Mode 3: Maximum Cost from Price and Target Margin
The third mode helps when your selling price is fixed or constrained, and you need to know how much you can afford to pay for a product while still achieving a desired margin. This can guide supplier negotiations and internal cost control.
Formula for Cost from Margin
Rearranging for Cost gives:
For example, if your selling price is 100 and you want a 35% margin, your maximum allowable cost is 100 × (1 − 0.35) = 65. The calculator also shows the resulting profit per unit, margin and markup if you actually achieve that cost.
Why Margin and Markup Are Not the Same
Margin and markup often get mixed up, but using the wrong one can lead to incorrect prices. If you intend to use a “30% margin” but mistakenly apply a 30% markup to cost, your actual margin will be smaller than you expect.
For example:
- Cost = 100
- Markup 30% → Price = 130 → Profit = 30 → Margin = 30 ÷ 130 ≈ 23.1%
- Margin 30% → Price = Cost ÷ (1 − 0.3) ≈ 142.86 → Profit ≈ 42.86 → Margin = 30%
The calculator shows both margin and markup for every scenario, so you always know exactly what your numbers mean.
Using the Profit Margin Calculator for Different Business Types
Although the formulas are simple, the calculator can be applied to many business models:
- Ecommerce and Retail: Test prices and discounts, compare supplier quotes, and set target margins for product categories.
- Wholesale and Distribution: Check margins at different volume-based prices and ensure profitability across customer tiers.
- Service Businesses: Translate hourly or project-based pricing into effective margins after accounting for delivery costs.
- Manufacturing: Combine unit production cost with overhead allocation and see how selling price changes affect margin.
- Agencies and Freelancers: Estimate implied margin after subcontractor costs or advertising spend.
Practical Tips for Pricing with Margin Targets
- Define minimum acceptable margins for each product or service category.
- Use the calculator to test “what if” scenarios before committing to discounts or promotional prices.
- Check margins after supplier price changes or currency fluctuations.
- Combine margin analysis with volume forecasts to see how total profit changes with quantity.
- Remember that overhead, marketing and admin costs also need to fit within your gross margin structure.
Examples of Profit Margin Scenarios
Example 1: Checking an Existing Product
You currently buy a product for 12 and sell it for 20. Using the Margin & Markup mode, the calculator shows a profit of 8 per unit, margin of 40% and markup of 66.67%. If you sell 500 units, total revenue is 10,000, total cost is 6,000 and total profit is 4,000.
Example 2: Setting a New Price from Margin
Your cost is 18 and you want a 55% margin. In the Price from Margin mode, you enter 18 as cost and 55% as target margin. The calculator outputs a required selling price of 40. Then it shows profit of 22, margin of 55% and markup of 122.22%.
Example 3: Maximum Cost at a Fixed Price
You plan to sell a new item at 60 but want at least a 35% margin. In the Cost from Margin mode, you enter price 60 and margin 35%. The calculator returns a maximum allowed cost of 39. This shows that if suppliers quote higher than 39, you will either need to raise price or accept a lower margin.
How to Use This Tool Effectively
- Start in the Margin & Markup tab to review current products, using actual cost and price.
- Switch to Price from Margin when planning new products or revising price lists.
- Use Cost from Margin when negotiating with suppliers or estimating maximum spend on fulfillment.
- Test different margin targets to see how much room you have for discounts and promotions.
- Apply quantity input to translate unit economics into total profit and revenue.

Frequently Asked Questions About Profit Margin and Markup
Learn how to interpret margin, markup, required selling price and maximum cost using this calculator.
Higher margins provide more profit per unit, but very high prices may reduce demand. The best margin balances profitability with competitive pricing and customer value.
Acceptable margins vary by industry, cost structure and business model. Many businesses use the calculator to test whether specific products meet their internal margin targets rather than rely on a single “good” number.
Yes. If you want to analyze fully loaded margins, you can include a share of overhead, marketing, shipping and other costs in the cost figure you enter for each unit.
No. The calculator focuses on cost, price, margin and markup. You can adjust your cost or price inputs to reflect taxes, platform fees or payment processing if you want to see their impact on margin.
Yes. You can treat the recurring price and recurring cost per period as your unit price and unit cost. For deeper subscription analysis, you may combine this with tools such as lifetime value or churn calculators.
No. All calculations are performed in your browser using the values you enter. You can change or clear numbers at any time.
