Therapy Calculators
Free calculators for physical therapists, occupational therapists and speech-language pathologists. Each one answers a single question, shows the math, and runs in your browser without a login.
Which calculator do you need?
| Your question | Calculator | What you enter |
|---|---|---|
| “What time can I leave, based on my billable minutes and target?” | Therapy Productivity Calculator | Start time, billable minutes, target % |
| “Same question, but I take an unpaid lunch” | Productivity Calculator with Lunch Break | Plus lunch length |
| “I’m at work now. How much longer?” | Clock-Out Time Calculator | Clock-in time, paid hours, breaks |
| “What was my productivity % today?” | Productivity Percentage Calculator | Billable minutes, paid minutes |

Productivity and end-time calculators
Therapy Productivity Calculator
Turns billable minutes and a productivity target into your exact clock-out time. Example: 375 billable minutes at 85% from a 7:30 AM start means you’re done at 2:51 PM.

Productivity Calculator with Lunch Break
Same math, with an unpaid lunch added after your paid time. It answers the common question of whether lunch hurts your productivity. It doesn’t; it only moves your clock-out.

Clock-Out Time Calculator
For the middle of the day. Enter your clock-in time and required paid hours to see how much longer you have.

Productivity Percentage Calculator
Checks where your day actually landed, or tells you how many billable minutes your target needs (408 minutes for 85% of an 8-hour day).
