How to Calculate Therapy Productivity

Therapy productivity is your billable treatment minutes divided by your paid minutes, times 100. Here’s how to work it out from your own day in five steps, using a real-looking SNF timesheet as the example.

Quick answer: Productivity % = billable minutes ÷ paid minutes × 100. Take unpaid lunch out of paid minutes first.

Step 1: How many minutes were you paid?

Start with your clock-in and clock-out times, then take out any unpaid break.

Example: In at 7:00 AM, out at 3:30 PM, with a 30-minute unpaid lunch.

Time on site: 8 h 30 min = 510 minutes
Minus unpaid lunch: 510 − 30 = 480 paid minutes

Short paid breaks (20 minutes or less, under federal Department of Labor rules) stay in paid time.

Step 2: How many minutes were billable?

Add up the minutes your employer counts as productive. For most employers, that’s direct treatment time with the patient.

Patient	Minutes
A	45
B	38
C	53
D	30
E	45
F	52
G	40
H	45
I	38
Total	386

Ask your employer what else counts. ASHA’s 2025 survey found 40% of SLPs said nothing counts toward productivity when the patient isn’t present.

Step 3: Divide and multiply by 100

386 ÷ 480 × 100 = 80.4%

Step 4: Compare with your target

Target	Billable minutes needed	You had	Result
80%	384	386	2 minutes over
85%	408	386	22 minutes short

Step 5: Plan the gap

If you’re 22 minutes short of 85%:

One extra 30-minute session closes it
Or spread it across the week in the weekly productivity calculator
Or check midday next time with the pace calculator

Five steps: 510 minutes on site, minus 30-minute unpaid lunch equals 480 paid minutes, 386 billable minutes, 386 divided by 480 equals 80.4 percent, compared with an 85 percent target is 22 minutes short — Five steps to your productivity percentage

What are the most common calculation mistakes?

Leaving unpaid lunch in paid time. That makes your number look lower than it is.
Averaging daily percentages for a weekly number. Total the minutes instead.
Counting session time that wasn’t billable, such as waiting for a patient to arrive.
Mixing hours and minutes. Convert everything to minutes first.
