Post-construction cleaning teams can estimate labor-hours and a quote from measured area, their own productivity, separately timed tasks, crew size, listed costs, and a target margin. Choose either area-based base hours or a manual base-hours override; then add extra task hours once.
Open the post-construction cleaning quote calculator
Set area, productivity, and task hours
In area mode, enter a measured area and your team’s own productivity in area units per labor-hour. Base labor-hours equal area divided by that productivity. For example, 4,000 ft² at a user-entered 500 ft² per labor-hour gives 8 base labor-hours. The productivity is your estimate for the actual crew and scope; the calculator does not supply an industry rate or infer a debris multiplier.
You can instead enter a manual base-hours override. That value replaces the area/productivity result. Add separately timed task hours after either base method, so an override of 8 hours plus 2 hours of window or detail work still produces 10 labor-hours.
Separate labor-hours, crew time, and quote cost
Labor-hours measure total work across the crew. Crew elapsed hours equal total labor-hours divided by crew count, assuming workers can perform their work in parallel. Ten labor-hours assigned to two workers therefore gives 5 estimated crew hours; it does not reduce the labor cost to five hours.
Labor cost equals labor-hours times your loaded labor rate. Use a rate that already includes whatever labor burden you put into it; the calculator does not add that burden a second time. Add supplies, equipment, disposal, and overhead as separate lump sums. The quoted price uses your target margin: listed cost divided by (1 − margin). Enter the margin as a percentage from 0 through 99.999. It applies after the listed costs; omitted costs reduce the eventual margin.

The following inputs are illustrative values for checking arithmetic, not a cleaning price benchmark.
| Input or result | Calculation | Amount |
|---|---|---|
| Base labor | 4,000 ft² ÷ 500 ft² per labor-hour | 8 hours |
| Additional task | Entered separately | 2 hours |
| Total labor | 8 + 2 | 10 labor-hours |
| Crew elapsed | 10 ÷ 2 workers | 5 hours |
| Labor cost | 10 × 30 loaded rate | 300.00 |
| Supplies + equipment + disposal + overhead | 40 + 20 + 40 + 50 | 150.00 |
| Listed cost | 300 + 150 | 450.00 |
| Quote at 20% margin | 450 ÷ (1 − 0.20) | 562.50 |
Set the currency label to USD for this example. The tool exports the quote as an itemized CSV and PDF; use the downloaded quote as the handoff to the customer.
For routine office visits and monthly pricing, use the commercial cleaning calculator guide.
Review the downloaded quote
Check the scope, labor assumptions, loaded rate, and each cost line before sharing the exported files. The displayed estimate keeps total labor-hours, crew elapsed hours, listed cost, and margin-based quote distinct so the estimator can explain the result.
Build a quoting app with Atoms
Copy the prompt into an Atoms project chat to describe a saved-quote app. Atoms documents Atoms Cloud and connected Supabase as backend options; choose one. If you choose Supabase, enable and test row-level security policies for exposed tables. App users need server-enforced organization, owner, assigned-row, field, and export permissions; workspace builders and app users have different roles. Verify a saved edit after reload and test allowed and denied actions with each role. Atoms Cloud · Connect Supabase · Supabase row-level security

Build a post-construction cleaning quote app for a cleaning team. Store quotes in stable-ID tables: quote_versions, scope_lines, labor_assumptions, and cost_lines. Preserve each quote version and the inputs used to calculate it. Import rows by stable source ID and deduplicate repeat imports.
Collect either measured area plus the team’s own positive area-per-labor-hour productivity, or a manual nonnegative base labor-hours override. The manual override replaces the area/productivity calculation; add separately timed task hours after either base-hours method. Collect an integer crew count from 1 to 100, a nonnegative loaded labor rate, nonnegative supplies/equipment/disposal/overhead amounts, a margin percentage from 0 through 99.999, and a three-letter currency label. Do not infer debris multipliers, productivity, regional prices, taxes, or equipment costs. The loaded labor rate already includes the burden specified by the user; do not add that burden again.
Calculate base labor-hours = manual override when supplied, otherwise measured area / user productivity. Calculate total labor-hours = base labor-hours + additional task hours. Calculate labor cost = total labor-hours × loaded labor rate. Calculate listed cost = labor cost + supplies + equipment + disposal + overhead. Calculate quote = listed cost / (1 − margin as a decimal). Calculate crew elapsed hours = total labor-hours / crew count, and label it as an estimate that assumes the crew can work in parallel. Keep labor-hours, elapsed hours, cost, and quote as separate results.
Synthetic acceptance example: area 4,000 ft2; user productivity 500 ft2 per labor-hour; additional tasks 2 labor-hours; crew 2; loaded rate 30 USD per labor-hour; supplies 40; equipment 20; disposal 40; overhead 50; margin 20%. Expected base = 8 labor-hours, total labor = 10 labor-hours, elapsed = 5 hours, labor cost = 300, listed cost = 450, quote = 562.50 USD. Show the same formulas and component lines in the quote.
Export an itemized CSV and quote PDF that match the displayed inputs and results. Validate positive finite area/productivity in area mode, nonnegative finite override/additional hours/rates/costs, integer crew 1–100, margin input from 0 through 99.999 percent, converted to a decimal for the formula, and a three-letter currency code. Reject blank, nonfinite, or out-of-range values. No external API or payment integration is required.
Use two app roles: Estimator can create and edit assigned quotes; Reviewer can read and approve a quote version. Enforce organization, owner, assigned-row, field, and export permissions on the server. Workspace builders are not app users. Choose Atoms Cloud or connected Supabase as the single backend. If Supabase is selected, enable and test row-level security on exposed tables. Persist one edit across reload, then test permitted and denied record, field, and export actions for each role. Report each check that remains incomplete.
