Frequently Asked Questions
Common questions about using the contractor calculator.
Yes, the contractor calculator is completely free to use. There are no hidden fees, subscriptions, or limitations. You can calculate as many projects as you need and use all features including invoice generation and report exports.
Profit Margin is calculated as (Net Profit / Revenue) x 100. For example, if your revenue is $100,000 and your net profit is $20,000, your profit margin would be 20%. This tells you what percentage of your revenue is actual profit.
Profit Margin is the percentage of revenue that is profit (Profit / Revenue x 100). Markup is the percentage added to costs to get the selling price (Profit / Total Costs x 100). For example, if your cost is $80 and you sell for $100, your markup is 25% but your profit margin is 20%.
The break-even point is the minimum revenue needed to cover all your costs with zero profit. It equals your Total Costs (Materials + Labor + Equipment + Overhead). Any revenue above this point becomes profit; below this point, you are operating at a loss.
Yes, you can save your projects using the 'Save Project' button. Projects are saved in your browser's local storage, so they will be available when you return to the calculator. You can save multiple projects and load them anytime.
Yes, you can optionally include tax in your calculations. You can enter tax as a percentage of profit or as a fixed dollar amount. The calculator will automatically deduct the tax from your gross profit to show the net profit after taxes.
Yes, the calculator includes a built-in invoice generator. Once you have entered your project details and costs, you can generate a professional contractor invoice with your company information, client details, itemized costs, and payment terms.
The calculator includes five main cost categories: Material Costs (with quantity and per-piece pricing), Labor Costs (number of workers x cost per worker), Equipment Costs (machines, rentals, tools), Overhead Costs (fuel, office, transport), and optional Tax deductions.
