A contractor markup calculator helps you set the right bid price for construction and service jobs. Enter your material costs, labor, and overhead percentage, then choose a desired markup or profit margin to calculate the final bid price, profit amount, and a full cost breakdown. Getting the math right means you cover all costs and earn a fair profit on every project.

Markup vs Margin: Your markup of -- produces an effective margin of -- and an effective markup of --. Margin is profit as a share of the bid price; markup is profit as a share of total cost. A 20% markup yields only a 16.67% margin.
How to Use the Contractor Markup Calculator
Pricing a construction or service job correctly is the difference between a profitable business and one that slowly bleeds money. This contractor markup calculator walks you through the standard cost-plus pricing method used by contractors, remodelers, and tradespeople across every specialty.
Step 1: Enter Your Direct Costs
Start by entering your material cost — the total price of all materials, supplies, and purchased items for the job. Then enter your labor cost — the total wages, including payroll taxes and workers' comp, for all crew members on the job. Together, materials and labor form your base cost (also called direct cost).
Step 2: Set Your Overhead Percentage
Overhead covers the indirect costs of running your business: insurance, vehicle expenses, office rent, tools, licenses, advertising, and administrative staff. Most contractors use an overhead rate between 10% and 25% of direct costs. The default is 15%. The calculator applies this percentage to your base cost (materials + labor) and adds it to get your total cost.
Step 3: Choose Markup or Margin Mode
You can price your job using either markup or margin — they are two different ways to express the same profit. In markup mode, you specify a percentage to add on top of your total cost (e.g., 20% markup on $10,000 cost = $12,000 bid). In margin mode, you specify the share of the bid price that should be profit (e.g., 20% margin means the bid is total cost / (1 - 0.20) = $12,500). Margin mode always produces a higher bid price for the same percentage because the base is larger.
Step 4: Review the Results
After clicking Calculate, you will see the bid price, profit amount, effective margin and markup percentages, and a full cost breakdown table showing materials, labor, overhead, profit, and bid price with each item's share of the total bid. Use this breakdown when presenting estimates to clients or reviewing job profitability after completion.
Common Contractor Pricing Mistakes
The most frequent mistake is confusing markup with margin. Adding 20% to your cost gives you a 20% markup but only a 16.67% profit margin. If your accountant says you need a 20% margin, you actually need a 25% markup. Another common error is forgetting to include overhead — quoting materials plus labor without accounting for insurance, fuel, and administrative costs means you are slowly losing money on every job.
Frequently Asked Questions
Is this contractor markup calculator free?
Yes, the contractor markup calculator is completely free with no signup or account required. Use it as many times as you need to prepare bids and estimates.

Absolutely. All calculations run locally in your browser. No cost data, bid prices, or project details are ever sent to a server or stored anywhere.
What is the difference between markup and margin for contractors?
Markup is the percentage added on top of your total cost to arrive at the bid price. Margin is the percentage of the bid price that becomes profit. A 20% markup only yields a 16.7% profit margin. Confusing the two is the most common pricing mistake in contracting.
What is a typical contractor overhead percentage?
Contractor overhead typically ranges from 10% to 25% of direct costs, depending on the size of the business. Overhead includes insurance, vehicle costs, office expenses, tools, licenses, and other costs not tied to a specific job.
What markup should a contractor charge?
Most contractors use a markup between 10% and 50%, depending on the trade and market. Remodeling contractors often mark up 35-50%, while general labor contractors may use 15-25%. The right markup should cover overhead and leave a reasonable net profit.
How do I calculate a bid price from cost and desired margin?
To price to a target profit margin, divide your total cost by (1 minus the margin as a decimal). For example, if total cost is $10,000 and you want a 20% margin: $10,000 / (1 - 0.20) = $12,500. Do not simply add 20% to the cost, as that gives a markup, not a margin.
What costs should I include in my contractor estimate?
Include all direct costs: materials, labor (including subcontractors), equipment rental, permits, and delivery fees. Then add overhead as a percentage to cover insurance, vehicle, office, and administrative costs. Finally, apply your desired markup or margin for profit.
