What counts as gross margin in a cleaning contract?

Gross margin is revenue minus direct costs like labor, supplies, and equipment for that specific job. For a $1,850 monthly contract at 25% margin, you keep $462.50 after paying crew wages, chemicals, and other variable costs. The rest covers overhead and profit.

How do I estimate months to replace revenue from a lost account?

Track how long it typically takes from when a client cancels until a new contract of similar size starts generating revenue. Include your sales cycle, onboarding time, and any gap between contracts. Most contractors see 1 to 4 months depending on market conditions and pipeline health.

Why does management time matter in churn cost?

Every lost client requires hours for exit meetings, crew reassignment, schedule adjustments, and replacement sales efforts. At 6 hours per churn and a $50 per hour management cost, that adds $300 in overhead beyond the lost revenue itself.

Expected annual churns

Calculate the full financial impact when a commercial cleaning client cancels their contract. The tool accounts for lost margin, revenue replacement time, acquisition costs, operational disruption, and management overhead to show the true cost of each lost account.

Instruction

Enter your monthly contract value and gross margin percentage for the account.
Set how many months it takes to replace lost revenue and your client acquisition rate.
Read the total cost per churn including lost profit, replacement time, and overhead.

Worked example

You lose a $1,850/mo account at 25% gross margin, expect 2 months to replace it, and burn 6 management hours on the transition.

Replacement cost lands near $2,670 for that churn (~$8,000/yr if it happens three times) — fund retention if it is cheaper than replacing.
