Contractor Project Estimator
Use this calculator to accurately estimate your project costs, desired profit, and the final price for your clients. Understanding these metrics is crucial for sustainable business growth and competitive bidding.
(e.g., insurance, admin, tools, vehicle costs)
(e.g., 20% means 20% of the final price is profit)

Understanding Your Project Estimate
For contractors, accurate project estimation is the bedrock of a profitable and sustainable business. This calculator helps you move beyond guesswork by breaking down all the critical financial components of a project.
Key Components Explained:
- Total Material Cost: This is the direct cost of all raw materials, supplies, and components required for the project. Accurate tracking of material costs is fundamental to any estimate.
- Estimated Labor Hours: The total number of hours you anticipate your team (including yourself) will spend directly working on the project. This is a critical factor in determining labor costs.
- Desired Hourly Rate for Labor: This is the rate you aim to pay your workers or value your own time per hour. It covers wages, benefits, and any direct labor-related expenses.
- Overhead Percentage: Overhead refers to the indirect costs of running your business that aren't directly tied to a specific project but are necessary for operations. This includes things like office rent, utilities, insurance, vehicle maintenance, administrative salaries, marketing, and tool depreciation. By applying a percentage to your subtotal cost, you ensure these costs are covered.
- Desired Profit Margin (% of Final Price): This is the percentage of the final project price that you want to retain as profit after all costs (materials, labor, and overhead) are covered. A healthy profit margin is essential for business growth, reinvestment, and financial stability.
How the Calculator Works:
The calculator systematically builds up your project price:
- It first determines the Total Labor Cost by multiplying your estimated labor hours by your desired hourly rate.
- Then, it calculates the Subtotal Cost by adding the Total Material Cost and the Total Labor Cost.
- Next, it applies your Overhead Percentage to the Subtotal Cost to determine the Estimated Overhead Cost.
- These three components are summed to give you the Total Operating Cost – the true cost of delivering the project before any profit.
- Finally, it calculates the Estimated Final Project Price by applying your desired Profit Margin. This is crucial: if you want a 20% profit margin, it means 20% of the *final price* is profit, not 20% of your operating cost. The calculator adjusts for this to ensure your profit target is met.
- The Desired Profit Amount is then simply the difference between the Final Project Price and the Total Operating Cost.
- The Effective Hourly Rate provides insight into the total revenue generated per labor hour, after accounting for material costs, and covering labor, overhead, and profit. This helps you understand the overall value generated by your labor efforts.
Example Scenario:
Let's say you're bidding on a small bathroom renovation:
- Total Material Cost: $5,000
- Estimated Labor Hours: 80 hours
- Desired Hourly Rate for Labor: $75/hour
- Overhead Percentage: 15%
- Desired Profit Margin: 20%
Based on these inputs, the calculator would show:
- Total Labor Cost: $6,000.00 (80 hours * $75/hour)
- Subtotal Cost: $11,000.00 ($5,000 materials + $6,000 labor)
- Estimated Overhead Cost: $1,650.00 (15% of $11,000)
- Total Operating Cost: $12,650.00 ($11,000 subtotal + $1,650 overhead)
- Desired Profit Amount: $3,162.50
- Estimated Final Project Price: $15,812.50 (This is $12,650 / (1 – 0.20))
- Effective Hourly Rate: $135.16 (($15,812.50 – $5,000) / 80 hours)
This detailed breakdown allows you to present a competitive yet profitable quote, ensuring all your costs are covered and your business earns the profit it needs to thrive.
