Free construction calculators for contractors

A construction calculator does a job’s math for you: quantities, costs, prices or rates. Some are handheld devices; others are free web tools like these. The ECHOPS calculators handle pricing math: turning cost into a price with the markup calculator, finding your true labor cost per hour and comparing what your software costs each month.

Start with your labor cost, because every price depends on it. The labor cost calculator adds payroll taxes, workers’ comp, benefits, unbilled time and overhead to a wage and gives you a billing rate. Then use the markup calculator to price jobs at the margin you need, and check totals against the pricing guides.

Yes. All three are free to use, with no account and nothing to sign up for, and each one shows the math behind the answer. The free contractor templates on this page come as a printable PDF plus an editable Word or Excel file.

It depends on the math you do most. For field measurements and quantities, look at dedicated construction calculators and phone apps. For pricing, what matters is that the math matches how you price: true labor cost, overhead and margin. These contractor calculators cover pricing, and in ECHOPS the same markups live in your price book.

A calculator answers one question at a time; estimating software keeps the answers. In ECHOPS, price book items carry their own cost parts, markups and waste, and price by size, unit or allowance, so every estimate prices the same way.
