Method & assumptions
  • Labor hours = sum of (qty × hours per unit × crew).
  • Overhead applies either to labor only or to total cost depending on your selection.
  • Price mode: Margin uses price = cost / (1 - m). Markup uses price = cost × (1 + m).
  • Good/Better/Best: multipliers increase labor and material before overhead and profit. Best includes a small warranty reserve.
  • Sales tax (if entered) applies to the final price only and is displayed separately.

About this free job bid calculator

Margin vs. markup

Margin is profit as a percentage of the final price. Markup is a percentage added to cost. The numbers are not the same. Many pros price by margin because it keeps net profit consistent.


Job bid estimator FAQ

What if I have multiple labor rates?

Set a default rate and override per task where needed. For crews with mixed rates, enter an average rate or split the task into two lines.

How should I use the Good / Better / Best quotes?

Good is your lean, standard offer. Better adds time and material for higher quality or flexibility. Best includes additional time, upgraded materials, and a small reserve that covers callbacks and extended warranty expectations.

Does this handle taxes?

Enter a sales tax percentage to display tax on the final price. Tax rules vary; confirm with your jurisdiction and accountant.
