Calculate fixed-price freelance projects with clear costs, buffers, and profit — without guesswork.
Most freelancers calculate project prices based on hours and an hourly rate. What gets missed are meetings, scope uncertainty, revisions, and negotiation time.That’s why fixed-price projects often feel stressful — and end up underpriced.
DevCalc is a Google Sheets pricing calculator designed for fixed-price freelance work.Instead of guessing a number, you calculate a base cost, add explicit buffers, and apply profit on top — transparently and consistently.
All inputs are editable in Google Sheets: hours, rate, buffers, and profit.Change any value and the final price updates automatically.
