How to get a useful price from either calculator

  1. Define the actual work and surfaces or tasks included.
  2. Calculate labor hours and the full cost of labor, including owner time when relevant.
  3. Add chemicals or materials, equipment costs, travel, disposal and a reasonable overhead allocation.
  4. Choose a target margin that fits your business and risk.
  5. Review the suggested selling price and compare it with your scope, customer expectations and market conditions.
  6. Save the numbers you used so you can compare the estimate with the final job outcome.
Margin and markup are different: If your included job cost is $140 and you want a 30% gross margin, use $140 ÷ (1 − 0.30) = $200. That produces $60 gross profit on the included costs, or 30% of the selling price. A 30% markup on $140 would be $182, which is a margin of approximately 23.1%.

After calculating, make the job clear to the customer

A pricing result is not a complete customer agreement. A professional estimate should identify the service address, included work, exclusions, customer preparation, price, payment terms and approval requirements. A three-option proposal may help present genuinely different scopes without disguising the underlying price.
