Know Your Real Profit on Every Invoice
Profit Is Not the Same as Revenue
Many freelancers celebrate rising revenue without checking how much of it is actually profit. Once you subtract the direct cost of delivering a job, the amount you keep may be far smaller than the number on the invoice. This calculator makes the real figure visible: enter the invoiced amount and the costs you paid to fulfil the job, and see your profit, cost ratio and gross margin instantly.
What Margin Really Tells You
Gross margin measures how efficiently every dollar or pound of revenue covers its direct costs. A healthy margin gives you room to absorb overhead, taxes and the occasional bad job. By reporting cost ratio alongside margin, this calculator also reveals how much of your revenue is consumed before you earn, helping you spot jobs where the pricing is too thin.
Quote with a Target Margin
Rather than guessing what to charge, enter a target gross margin and the calculator reverses the numbers: it divides your direct cost by one minus the target margin to show the minimum invoice amount you need. This turns a known cost into a defensible quote and provides a quick sanity check before you send a proposal.
How to Use This Calculator
Enter the amount on your invoice and the direct costs to deliver it. The results update live as you type. Optionally add a target margin to see the minimum amount you should charge. Use the copy button to snapshot the result into your project notes, and remember that fixed overhead and taxes must also be covered on top of the direct cost you enter.
