Every ABA practice owner knows RBT turnover is a problem. Fewer have priced it. When an RBT leaves, the practice absorbs recruiting time, onboarding and the 40-hour training requirement, competency assessment and BCBA supervision hours, payroll during a non-billable ramp, and — most expensively — lost or disrupted client hours while a replacement is found. There is also a clinical cost that does not appear in any spreadsheet: continuity matters to outcomes, and families notice.
Where the money actually goes
Four buckets. Recruiting: job posting spend, screening time, interview hours from people whose time is otherwise billable. Onboarding: the 40-hour training requirement, competency assessment, credentialing steps, and administrative setup — all paid, none billed. Supervision: BCBA hours diverted from billable supervision and program development into new-hire training, which quietly reduces the practice's highest-value capacity. And the revenue hole: authorized client hours that go uncovered or get reduced while the position is vacant, which is usually the largest single component and the one owners underestimate most.
Why RBTs leave
The reasons reported across the field are consistent: pay that does not compete with adjacent roles requiring less specialized skill, inconsistent hours that make income unpredictable, unpaid drive time between clients, insufficient supervision and support with difficult cases, no visible path forward, and burnout from a genuinely demanding role. Notably, most of these are structural rather than personal, which means they are addressable by practice design rather than by hiring better people.
What retention actually costs to fix
The interventions that matter are not free, which is why they get deferred. Guaranteed-hours or salaried models make income predictable but require the practice to absorb schedule variance. Paid drive time addresses a real grievance and adds direct cost. Meaningful supervision beyond the required minimum consumes BCBA capacity. Tuition support toward BCBA certification creates a visible path but costs money before it returns any. And competitive pay is simply competitive pay. Each of these is an investment with a payback period rather than an expense — which is exactly the profile that justifies financing when cash is the constraint.
Running the comparison
The calculation that makes the decision obvious: estimate your annual turnover count, multiply by your practice's real per-departure cost including uncovered client hours, and compare that total to the annual cost of the retention measures you are considering. In practices with meaningful turnover, the retention spend is frequently smaller than the turnover cost it prevents — but it requires cash up front against savings that accrue over the following year, which is why practices that are cash-constrained stay stuck paying the more expensive option indefinitely.
Funding the transition
Where a retention investment has a defensible payback — a pay increase that measurably reduces departures, a guaranteed-hours model that stabilizes staffing, a cohort of tuition-supported RBTs moving toward BCBA — that is precisely the bounded, measurable use case that revenue-based funding is built for. It is underwritten on the practice's deposit history rather than tax returns, funds in days, and is sized to a defined need rather than serving as open-ended runway. The test before taking it: model the remittance against your weakest recent month, and check combined daily debits against average daily deposits.
