Managing Labor Costs Across Multiple Job Sites
When you're running multiple job sites simultaneously — whether for construction, facility services, event staffing, or cleaning contracts — keeping labor costs separated by location is essential for accurate project profitability tracking and billing.
This calculator lets you enter crew size and daily rate for up to three sites, instantly computing the labor cost for each site, the grand total, and what percentage of total labor spend each site represents.
When workers split their day between sites, prorate their daily rate proportionally. A worker paid $200/day who works 6 hours at Site A and 2 hours at Site B should be allocated $150 to A and $50 to B. Consistent prorating keeps your cost allocation defensible for both client billing and tax purposes.
For sites beyond three, run this calculator in stages or export your results to a spreadsheet for ongoing tracking across larger operations.
Frequently Asked Questions
Use a daily time log showing each worker's hours per site. For flat-rate daily workers, convert to an hourly equivalent and bill by actual hours per site. Many contractors use basic time-tracking apps or paper logs to maintain this record.
For most small businesses, the IRS doesn't require per-site labor breakdowns on your tax return. However, if you bill different clients for different sites, accurate records protect you in case of disputes or audits.
