Minimum Profitable Account Size
How small can an account be before it's not worth servicing?
Why this comes up
Small accounts have a way of costing more, proportionally, to service than large ones, since account management and recruiter attention don't scale down linearly with account size. This engine finds the exact revenue level below which servicing cost eats an account's contribution entirely, converted to whichever unit you actually track, active workers, weekly hours, or assignments.
How we calculated this
Break-Even Revenue = Fixed Account Service Cost / Contribution Margin Before Fixed Cost Break-Even Alternate Unit = Break-Even Revenue / Average Revenue per Unit
Worked example: $4,000/mo fixed account service cost, 25% contribution margin before fixed cost, solving in active workers at $2,500/worker average revenue.
Break-Even Revenue = 4,000 / 0.25 = $16,000/mo Break-Even Active Workers = 16,000 / 2,500 = 6.4 workers
What this means
- An account below this revenue level is losing money once fixed servicing cost is counted, regardless of how healthy its raw contribution margin looks before that cost is subtracted.
- Converting to active workers, hours, or assignments makes this a practical operational check, easy to compare against an account's actual current or projected size.
- A contract that's individually profitable on paper can still be below this threshold, worth renegotiating scope, repricing to cover servicing cost, or genuinely not worth taking on.
Common mistakes
- Evaluating a small account's profitability on contribution margin alone, missing that fixed servicing cost consumes a much larger share of a small account's revenue than a large one's.
- Using a company-wide average fixed account service cost rather than a realistic figure for a genuinely low-touch, small account.
- Not converting the break-even revenue figure into a unit that's actually meaningful for a quick go/no-go check on a prospective small account.
Frequently asked questions
What counts as "fixed account service cost"?
The baseline account management and administrative cost that doesn't scale with account size, onboarding, minimum reporting, and basic relationship management, regardless of how small the account is.
Which unit should I solve in?
Whichever one you actually track and compare accounts by; active workers is common for contract staffing, assignments for project-based or direct-hire-heavy books.
What should I do with an account below this threshold?
Consider repricing to cover the fixed cost, consolidating servicing across several small accounts, or declining new accounts of a similar size unless there's a strategic reason to take them on anyway.
Limitations
Assumes fixed account service cost and contribution margin stay constant regardless of account size; a genuinely different account type may need its own separate fixed-cost estimate.
