Post-Construction Cleaning Calculator: Build Your Job Price

◆ Last updated September 14, 2026

A second visit, hard-to-reach glass or dust left by another trade can change the job. Write down the work you are quoting before you put a price beside it. This tool is for cleaning business owners quoting that agreed work.

Use the free post construction cleaning calculator

All amounts are in USD. Enter totals for the whole job, across all visits, except travel, which is entered per visit. The tool uses your hours and costs; it does not guess how fast your crew will clean. Load the made-up example to see how it works, then replace every value.

The calculator does not send or save the values you enter. Leaving or reloading the page may lose them. Use the worksheet below to keep a copy. If the tool does not load, the formula and worked example further down still show each step.

Download the editable estimate worksheet

Download the free post-construction estimate (.xlsx). No email signup is needed. The worksheet starts with the same made-up job as the calculator. Yellow cells are yours to change; other cells work out the result.

Save a copy for each job. Fill every number, choose the phases and write the included work and exclusions. Enter 0 when a cost does not apply. A blank field means you have not finished the estimate. In the sheet, enter a margin as a percent, such as 25%; in the web tool, type 25 in the margin field.

Walk the site and write the scope

Scope means the work included in your price. Walk through with the contractor or person who will approve the clean. Measure the areas you will actually clean. ServiceMaster’s cost guide also separates cleanable area from the full building and stresses a clear scope.

• List rooms, floors, surface types and what is being handed over. Note fragile finishes and work that needs a specialist.
• Choose the phases: rough clean, final clean, touch-up, or a clear mix. Write the tasks for each; the names alone do not define the work.
• Count windows and detailed tasks. State which glass faces, frames or other parts are included and how they can be reached safely.
• Agree visits, access times, keys, parking, power and water. Ask whether other trades will still be working.
• Name who removes building waste, who approves extra work and who signs off the clean. Put excluded areas and tasks in writing.

Unknown dust or hazardous material needs a qualified, site-specific assessment before work is priced or started. For covered construction work, OSHA’s silica standard restricts dry sweeping and compressed-air cleaning where they could add to silica exposure, with stated exceptions. A calculator cannot choose a safe method or the right protective equipment.

Estimate hours without counting the crew twice

A cleaner-hour is one cleaner working for one hour. One cleaner working two hours uses two cleaner-hours. Make a task list, estimate the labor for each task and add setup and final checks. Use records from similar jobs where you have them. Review difficult surfaces and access on site.

Enter that total as base cleaner-hours for every selected visit and phase. For example, 40 cleaner-hours ÷ 4 cleaners = about 10 crew working hours. That leaves out breaks, travel and site delays. A larger crew may need a different plan; changing crew size in this tool only changes the time estimate, not the labor bill.

Choose how to count windows and detail work

Choose Included if base hours already cover all window and detail tasks. The extra-hours field then adds nothing. Choose Separate only when those tasks are missing from base hours, and enter their total extra cleaner-hours. Do not enter the same window work in both fields.

The phase choices describe your quote. They do not apply a hidden fee or a fixed time multiplier. The number of visits multiplies travel only. You must include the labor and other costs of all visits yourself.

Add each job cost once

• Staff cost: pay plus your employer staff costs per cleaner-hour. Include your own cleaning work, even if you take drawings rather than wages.
• Supplies: what you expect to use on this job.
• Equipment: rental, or a fair job share of owned equipment costs. Owning a machine does not make its upkeep free.
• Travel per visit: vehicle costs, parking and paid travel time. If travel labor is already in your base hours, leave that labor out here.
• Waste: agreed disposal costs. Enter 0 if haul-away is excluded, and say so in the scope.
• Share of business costs: a job share of office, insurance and similar bills that are not in another line.

Add any cost you expect to pay before relying on the result. Tax is a separate amount you enter after checking what applies to your job and location. The tool does not select a tax rate or decide whether tax is due.

How the price is worked out

Listed cost = labor + supplies + equipment + travel + waste + share of business costs. Each cost line rounds to cents before the total is added.

Price before tax = listed cost ÷ (1 − target margin). A margin is the share of your price left after the costs you counted. For a 25% margin, divide by 0.75. Adding 25% to cost is a markup; it leaves a smaller share of the final price.

Use a margin from 0 to below 100%. A 0% margin leaves nothing above the listed costs. The amount left is not a promise of net profit: an omitted cost still needs to be paid.

A filled example: final clean of 2,500 sq ft

These numbers are made up to teach the method. They are not market rates or a claim about how long your site will take. The example covers one final-clean visit, with windows and detail work inside the 40 cleaner-hours. Haul-away and later touch-up visits are excluded.

Item	Made-up job
Labor: 40 cleaner-hours × $25	$1,000.00
Supplies	$75.00
Equipment	$50.00
Travel: one visit	$100.00
Waste: haul-away excluded	$0.00
Share of business costs	$50.00
Total listed costs	$1,275.00
Price at 25% margin: $1,275 ÷ 0.75	$1,700.00
Amount left after listed costs	$425.00
Price per sq ft: $1,700 ÷ 2,500	$0.68

Tax is entered as 0 in this example. The $0.68 per square foot is a result of the job costs. Do not carry it to another building without checking that building’s work, hours and costs.

Change the estimate when the work changes

Suppose the same made-up job needs a second visit and only travel rises by $100. The listed cost becomes $1,375, and the price becomes $1,833.33 at 25% margin. That covers no extra cleaning time. If the return visit takes more hours, add those hours too.

Or suppose windows were excluded from the base hours and you add eight separate detail hours at $25. Labor rises by $200. Listed cost becomes $1,475 and the price becomes $1,966.67. Leave those extra hours out if the original 40 hours already include them.

Agree a written change before taking on new debris, added rooms or another touch-up visit. Say what changed, the extra price and any change to the finish date. Do not charge a fixed percentage for every return visit without working out what it requires.

Before you send the quote

• Check the area, task list and totals against your site notes.
• State the included phases, visits, window work and exclusions.
• Confirm access, waste responsibilities, safe work arrangements and who accepts the job.
• Show the price before tax, any tax and the total. Add your payment terms and how extra work is approved.
• After the job, compare estimated hours and costs with what happened. Use that record for the next similar quote.

Use the commercial cleaning bidding guide to build the wider bid. The post-construction cleaning page covers choosing and planning this type of cleaning work.

Common questions

Does more square footage raise the price automatically?

No. Area is used to show your implied price per square foot. Your own labor hours and costs set the price. A larger area should prompt you to review the task list and hours; the calculator does not invent them.

Can I use it for rough, final and touch-up cleaning?

Yes. Select the phases you are quoting and include the work for all of them in your hours and costs. A later visit outside that scope needs a new estimate or agreed change.

What if the calculator is unavailable?

Use the editable worksheet or follow the formula and example above. Both show the same cost-based method. You do not need CleanerHQ to work out a price.
