Cost-Plus Pricing Calculator – Selling Price, Markup and Profit Margin
The Cost-Plus Pricing Calculator helps you turn your costs into clear, profitable prices. Instead of guessing or copying competitor prices, you can model selling price from cost and markup, find the price needed to hit a target profit margin and analyze how markup compares to margin. This is useful for product-based businesses, service providers, freelancers, agencies and anyone who wants a structured way to build prices from costs.
Cost-plus pricing is simple in concept, but easy to apply incorrectly in practice. Misunderstanding the difference between markup and margin or forgetting to include overhead can result in underpricing and thin profits. This calculator gives you a transparent framework for building and checking prices before you publish them or negotiate with customers.
How the Cost-Plus Pricing Calculator Works
The calculator offers three connected modes:
- Cost-Plus Pricing: Add a markup to cost to get selling price, total revenue and profit.
- Target Profit Margin: Start from desired margin and find the required price, profit and equivalent markup.
- Markup vs Margin Analyzer: Enter cost and current price to see actual markup, margin and profit per unit.
In all modes, you can optionally include overhead per unit and quantity to move from unit economics to total profit. This makes it easier to plan batches of products, projects or monthly service capacity.
Mode 1: Cost-Plus Pricing
In a basic cost-plus model, you start with your unit cost and add a markup to get your selling price. Cost can include direct materials, direct labour and any other variable cost per unit. You may also choose to include a portion of overhead (for example, rent, utilities, admin) as a per-unit amount.
Cost-Plus Pricing Formula
Here, Markup% is expressed as a decimal. For example, 40% markup becomes 0.40.
Once the calculator has unit selling price, it multiplies by quantity to get total revenue. Total cost is the sum of cost and overhead per unit multiplied by quantity. Profit and profit margin are then:
This shows whether your chosen markup creates a margin that meets your business goals.
Mode 2: Target Profit Margin Pricing
Many businesses think about profit in terms of margin, not markup. For example, you might want a 30% profit margin on the selling price. That means 30% of the price is profit and 70% covers cost and overhead. In this mode, you enter unit cost, overhead per unit and desired margin to solve for the required selling price.
Target Profit Margin Formula
If we define:
- C = Unit Cost
- O = Overhead per Unit
- M = Desired Profit Margin (as a decimal)
Then selling price is:
For example, if total unit cost C + O is 50 and you want a 30% margin, the denominator is 0.70. Selling price becomes 50 ÷ 0.70 ≈ 71.43.
The calculator also reports the equivalent markup on cost. If unit cost is 50 and selling price is 71.43, profit per unit is 21.43. Markup on cost is:
This helps you translate between margin-based and cost-plus mindsets.
Mode 3: Markup vs Margin Analyzer
The Markup vs Margin Analyzer is designed for when you already have a price and want to understand the underlying economics. By entering unit cost, selling price, overhead and quantity, you can see how much profit you really make per unit and how your markup compares to your margin.
Markup and Margin Formulas
For the same product, markup and margin percentages are different. A 40% markup on cost corresponds to a smaller margin on selling price. The analyzer mode makes this relationship clear so you can avoid confusion when comparing pricing strategies, competitor margins or industry benchmarks.
Markup vs Margin – Key Differences
Understanding the difference between markup and margin is essential when using cost-plus pricing:
- Markup is based on cost. If your cost is 50 and markup is 40%, profit is 20 and selling price is 70. Markup% = 20 ÷ 50 = 40%.
- Margin is based on selling price. In the same example, margin% = 20 ÷ 70 ≈ 28.57%.
Using markup when you intend to apply a target margin, or vice versa, can lead to underpricing. This calculator allows you to switch between both views and check whether your pricing structure is aligned with your goals.
Examples of Cost-Plus Pricing Calculations
Example 1: Simple Cost-Plus Pricing
A product has a unit cost of 30 and overhead per unit of 5. Total unit cost is therefore 35. You choose a markup of 40%.
Selling Price = 35 × (1 + 0.40) = 49.
If you sell 200 units, total revenue is 9,800, total cost is 7,000 and profit is 2,800. Profit margin is 2,800 ÷ 9,800 ≈ 28.57%.
Example 2: Target Margin Pricing
A service has unit cost of 60 (including labour and direct expenses) and no separate overhead allocation. You want a 35% margin on selling price.
Selling Price = 60 ÷ (1 − 0.35) = 60 ÷ 0.65 ≈ 92.31.
Profit per unit is 32.31 and markup on cost is 32.31 ÷ 60 ≈ 53.85%. The calculator shows both the price and the corresponding markup.
Example 3: Analyzing an Existing Price
Your current price is 120. Unit cost is 80 and overhead per unit is 10. Profit per unit is 30. Markup on cost is 30 ÷ 80 = 37.5%. Profit margin is 30 ÷ 120 = 25%. If you sell 500 units, total profit is 15,000.
If your target margin is 30%, the analyzer mode reveals that your current price is slightly below your goal and you may need to adjust pricing or reduce costs.
Why Use a Cost-Plus Pricing Calculator?
While market-based pricing and value-based pricing are important, cost-plus pricing remains a practical starting point in many situations. A calculator helps you:
- Ensure that prices cover both direct costs and overhead.
- Check whether markups translate into healthy profit margins.
- Compare different pricing scenarios quickly.
- Understand how small changes in cost or markup affect profit.
- Support negotiations with data-driven price logic.
Instead of relying on rough rules of thumb, you can work with clear numbers and make more confident decisions.
Limitations of Cost-Plus Pricing
Cost-plus pricing is straightforward but not perfect. Some limitations include:
- It does not directly consider customer willingness to pay or perceived value.
- It may ignore competitor prices and market conditions.
- It assumes costs are known and stable, which may not be true in volatile environments.
- It can encourage cost inflation if margins are applied as a percentage of cost.
A practical approach is to use cost-plus calculations as a foundation, then adjust based on market research, value proposition and strategic positioning.
How to Use This Tool Effectively
- Start with the Cost-Plus Pricing tab to turn your known costs into a baseline selling price.
- Move to the Target Profit Margin tab when you have clear margin targets and want a precise required price.
- Use the Markup vs Margin Analyzer tab to check existing prices or evaluate competitor prices relative to your cost.
- Always include a realistic overhead per unit where possible, especially for small businesses and freelancers.
- Run multiple scenarios with different markups or margins to see how they change total profit at different quantities.

Find quick answers about markup, margin, selling price and how to use this cost-plus calculator.
Both are valid, but margin is usually easier to align with business goals because it expresses profit as a percentage of selling price. This calculator lets you work in either direction and see how markup and margin relate.
You can convert your total overhead into a per-unit amount using expected volume and enter it in the overhead per unit field. The calculator then treats this as part of your unit cost when computing price and profit.
Yes. Treat one hour or one project as a unit. Your unit cost may include labour, tools, subscriptions and other expenses. The calculator will still compute selling price, margin and markup as usual.
The analyzer will show a negative profit per unit and negative margin. This indicates that the price is below breakeven, and you may need to adjust pricing, reduce costs or reconsider offering the product or service.
The tool focuses on core cost, markup and margin calculations. You can still use the results as a base and then apply taxes, discounts or additional fees separately according to your local rules and pricing policy.
Not always. Cost-plus pricing ensures costs are covered, but you should also consider customer value, competition and positioning. Many businesses combine cost-plus calculations with value-based and market-based insights.
