Expanding your OT practice means hiring the right support—but salary, benefits, and contractor rates vary dramatically depending on location, credentials, and role. Getting this budget right is the difference between scaling profitably and bleeding cash. Here's what you need to know before you post that job listing.
Understand the Role Differences
Occupational therapy assistants (OTAs) and contract therapists aren't interchangeable, and neither are their costs. OTAs hold a credential (COTA) requiring an associate degree and certification exam, while aides may have no formal qualification. Contract therapists are typically licensed OTs who work on a 1099 or fixed-term basis, offering flexibility but at a premium rate.
The role you need depends on your current workload and clinic structure. If you're drowning in documentation and patient intake, an aide might cost $16–$22/hour. If you need someone delivering direct patient care under limited supervision, a COTA runs $20–$30/hour plus payroll tax. A contract OT typically bills $35–$65/hour to your clinic, depending on specialization and market.
Full-Time Employee vs. Contract: Cost Breakdown
Full-time OTA salary in the U.S. averages $32,000–$38,000 annually, but add 25–30% for payroll taxes, workers' comp, and unemployment insurance. If you're paying $35,000 base, budget $43,750–$45,500 total loaded cost. Factor in 15+ days PTO, training time, and equipment allocation.
Contract OTs and PTAs cost more upfront but skip overhead: no benefits, no W2 taxes, no long-term commitment. A part-time contract OT working 20 hours/week at $50/hour runs $52,000/year before your clinic overhead, but they can ramp up or down with demand.
Hybrid approach: Many growing practices hire one full-time COTA ($45K loaded) and supplement with 1–2 contract therapists ($15K–$25K/quarter) during peak seasons or while building client volume.
Calculate ROI Before You Hire
Don't hire based on feeling understaffed—model the numbers first.
If your average OT session generates $120 in revenue and you see patients 6 hours/day:
- One full-time COTA delivering direct care could bill 4 additional patient hours/day
- That's $480/day or ~$120,000/year in additional gross revenue
- Against a $45K loaded salary, you net ~$75K profit (before overhead allocation)
But if you're only at 60% capacity, that math falls apart. Hiring too early wastes cash; hiring too late loses revenue and burns out existing staff.
Action step: Track your current utilization. If your OTs/PTAs are booked 70%+ of available hours and you have a waitlist, hiring pays for itself. Below 60% utilization, negotiate contractor rates instead.
Where to Find and Vet Candidates
- LinkedIn and Indeed: Cast wide net, but expect a 2–4 week hiring timeline and onboarding lag
- Local OT schools (community colleges, universities): Post internship or entry-level roles; graduates often accept lower pay for experience
- State OT associations: Many maintain job boards; these attract committed professionals
- Staffing agencies: Pay 15–25% markup on hourly rate, but handle payroll and if someone doesn't work out, you're out two weeks, not two months
- Networking events and AOTA conferences: High-touch but slower, better for finding contract specialists
Listing your open roles on Mercoly gives you direct access to vetted therapy professionals actively seeking opportunities in your area—and it also showcases your clinic's services and products to potential patients, all in one place.
Onboarding and Supervision Costs
Budget 4–6 weeks for a new COTA to reach 80% productivity. During that time, you're paying full salary while they shadow, ask questions, and build confidence. That's real cost; plan for it.
Supervision is non-negotiable if you hire OTAs—your OTs must spend 20–30% of their time overseeing OTA work, reviewing documentation, and ensuring compliance. Build this into your scheduling; don't assume OTAs are free labor that just get plugged in.
Contract therapists require minimal supervision but demand clarity upfront: scope, documentation standards, and patient handoffs.
Frequently Asked Questions
Q: Can I hire an occupational therapy aide without certification to save money? Yes, aides cost $16–$22/hour and can handle clerical work, setup, and patient transport—but they can't deliver billable patient care. Use them for behind-the-scenes work only.
Q: What's the difference between COTA and OTA hiring costs? COTAs (certified) cost 10–15% more and can deliver supervised direct patient care; OTAs (uncertified) cannot work in that role. If you need billable hours, hire a COTA.
Q: Should I hire full-time or use contract therapists as I grow? Contract therapists offer flexibility during growth phases and let you test demand before committing to salary. Switch to full-time hires once you hit consistent 75%+ utilization.
