How to Calculate Rate per Hour in ABA
Calculating the correct hourly rate for Applied Behavior Analysis (ABA) therapy is critical for both independent providers and agencies. Unlike standard hourly jobs, ABA billing typically involves complex reimbursement structures, "units" based on CPT codes, and significant overhead for supervision and administration. This guide explains the mathematics behind establishing a sustainable billable rate.
The ABA Rate Formula
To calculate a sustainable rate per hour, you must move beyond the therapist's base wage. You need to account for the "fully burdened" labor cost, overhead allocation, and your desired profit margin. The standard formula used by ABA practice managers is:
1. Calculate Fully Burdened Labor Cost:
Base Wage + (Base Wage × Tax/Benefits Load %)
Example: An RBT making $25/hr with a 20% benefits load has a labor cost of $30/hr.
2. Add Overhead Allocation:
Labor Cost + Overhead per Hour
Overhead includes rent, billing software, liability insurance, and BCBA supervision time not billed directly. If overhead is $15/hr, the total cost is $45/hr.
3. Apply Profit Margin (Gross Margin Method):
Total Cost / (1 – (Margin % / 100))
To achieve a 20% margin on a $45 cost, you do not simply add 20%. You divide by 0.80. The result is $56.25/hr.
Understanding ABA Billing Units
Most insurance funders (Medicaid, TRICARE, commercial payers) do not bill strictly by the hour. Instead, they utilize 15-minute units based on CPT codes (e.g., 97153 for adaptive behavior treatment).
- 1 Hour = 4 Units
- Rate per Unit = Hourly Rate / 4
When negotiating contracts or setting private pay rates, ensure your unit rate covers the full hour of operational costs. Even a small miscalculation of $1 per unit results in a $4 per hour loss.
Example Calculation Scenario
Let's assume an agency hires a Registered Behavior Technician (RBT):
- RBT Wage: $22.00/hour
- Taxes & Benefits: 23%
- Admin Overhead: $12.00/hour
- Target Margin: 15%
Step 1: Labor = $22.00 × 1.23 = $27.06
Step 2: Total Cost = $27.06 + $12.00 = $39.06
Step 3: Required Rate = $39.06 / (1 – 0.15) = $45.95/hour
Step 4: Unit Rate = $45.95 / 4 = $11.49 per unit.
Factors Affecting Your Rate
Geographic Location: Rates in metropolitan areas like New York or San Francisco will be significantly higher due to cost of living adjustments required for staff wages.
Certification Level: Rates differ drastically between services provided by an RBT (Registered Behavior Technician) versus a BCBA (Board Certified Behavior Analyst). BCBA rates typically carry a higher overhead due to the non-billable time spent on treatment planning and analysis.

// 1. Calculate Fully Burdened Labor Cost
// Wage + (Wage * Load%)
var laborCost = wage * (1 + (benefitsLoad / 100));
// 2. Calculate Break-even Cost (Labor + Overhead)
var breakEvenCost = laborCost + overhead;
// 3. Calculate Required Billable Rate based on Gross Margin
// Formula: Cost / (1 – Margin%)
var requiredRate = breakEvenCost / (1 – (margin / 100));
