A quote calculator, a bidding calculator and a job estimate calculator are searched for by contractors in different trades and mean the same thing: a worksheet that takes the cost of the job and produces the price to put on the quote or the bid. The cost is materials from the takeoff with waste, labor hours at a loaded rate and any subcontracted work; the price adds the overhead the job must recover and the markup that leaves a profit. The free job estimate calculator on this site is the estimate template: enter those inputs and it prints the material, labor, overhead, profit and total lines.
Cost first: the takeoff, the hours and the subs
Every calculator starts from the same three costs. Materials come from the takeoff, counted in the unit the supplier sells and priced from the current sheet, with a waste allowance the trade expects. Labor comes from the crew's hours on similar work at a loaded rate that already carries the burden. Subcontractors come in at their quoted price. A calculator that asks for fewer inputs than these is guessing on your behalf.
Price second: overhead and markup
The overhead percentage is the company's own, from last year's overhead divided by last year's direct cost, and it is applied before any profit is counted. The markup is the percentage on top of cost that produces the price; it is not the margin, which is the profit share of the price. A bidding calculator for a tendered job works the same way and then asks what the competition will do, which is a judgement the arithmetic informs rather than replaces.
Keep the calculation with the job
The value of a job estimate calculator is not the single answer but the record of every answer against the jobs that won and lost. The template on this site prices one job; Pro keeps each estimate against the customer and the job with the markup it went out at, so next season's bids are read against this season's results.
Questions people ask about quote calculator
What is the difference between a quote calculator and a bidding calculator?
None in the arithmetic. A quote goes to a customer who accepts or declines; a bid goes into a comparison against other bidders, so the bidding decision adds a judgement about the competition on top of the same cost-plus-markup number.
Is the job estimate calculator on this site free?
The template computes and prints for free; keeping estimates against customers and jobs, branding and exporting them is the paid subscription.
What inputs does the calculator need?
Material cost from the takeoff, a waste percentage, labor hours and a loaded hourly rate, subcontractor cost, an overhead percentage and a markup percentage.
