Which Productivity Formula Do You Need?
Use Case
Formula
Example
Personal daily output
(Actual ÷ Target) × 100
Completed 18/20 tasks = 90%
Labor productivity (revenue)
Revenue ÷ Hours Worked
$90,500 ÷ 3,840 hrs = $23.57/hr
Labor productivity (units)
Units Produced ÷ Hours Worked
19,600 bottles ÷ 280 hrs = 70/hr
Billable efficiency (therapy/legal)
Billable Min ÷ Paid Min × 100
360 ÷ 480 × 100 = 75%
Employee productivity
Output per Person ÷ Hours per Person
$25,000 ÷ 160 hrs = $156.25/hr
OEE (manufacturing)
Availability × Performance × Quality
90% × 95% × 99% = 84.6%
Most searches for “productivity calculator” want rows 1–3. Therapists, lawyers, and consultants want row 4. Use the tabs above to calculate any of these.
How to Calculate Productivity — Three Formulas Explained
What Is a Good Productivity Percentage? Benchmarks by Role
Role / Industry
Typical Target
Formula Used
Notes
SNF Therapist (PT/OT/SLP)
85–92%
Billable ÷ Paid
High burnout risk above 90%
Outpatient Therapist
80–88%
Billable ÷ Paid
Sustainable range
Knowledge Worker
70–80%
Tasks completed ÷ planned
Deep work sessions reduce non-billable
Call Centre Agent
75–85%
Talk time ÷ shift time
Includes hold and wrap-up
Manufacturing Worker
80–95% OEE
Availability × Performance × Quality
OEE above 85% = world class
Software Developer
60–75%
Focused coding hours ÷ shift
Meetings and context-switching are non-productive
Lawyer / Consultant
65–75%
Billable hours ÷ total hours
1,800 billable hrs/year = standard
Freelancer
60–70%
Revenue hours ÷ total hours worked
Admin, marketing, invoicing = non-billable
Personal Productivity vs. Labor Productivity — What's the Difference?
Personal efficiency measures whether you hit your own target. Labor productivity measures economic output per unit of input — it's used by managers and economists, not individuals tracking their day. Billable efficiency is a professional variant of personal efficiency used in industries that sell time.

Therapy & Clinical Productivity Calculators
If you're a therapist, clinician, or healthcare professional, use our discipline-specific calculators for more detailed analysis:
There are three main variants: Personal Efficiency = (Actual Output ÷ Target Output) × 100. Labor Productivity = Total Output ÷ Total Hours Worked. Billable Productivity = (Billable Minutes ÷ Total Paid Minutes) × 100. Choose the formula that matches your work type.
What is a good productivity percentage?
It depends on your role. SNF therapists target 85–92%, knowledge workers aim for 70–80%, software developers 60–75%, and lawyers/consultants 65–75%. See the benchmark table above for eight industry-specific targets.
How do I calculate labor productivity?
Divide your total output (revenue or units) by total hours worked. Example: $90,500 revenue ÷ 3,840 hours = $23.57 per hour. Use the Labor tab above to calculate yours instantly.
What is the difference between productivity and efficiency?
Productivity is the output-to-input ratio — how much you produce per unit of input. Efficiency measures actual output versus possible or target output — how close you are to your maximum capacity. A factory can be highly productive but inefficient if it wastes resources.
How do I calculate my personal productivity?
Divide tasks completed by tasks planned, then multiply by 100. Example: 18 tasks completed ÷ 20 planned = 90% personal productivity. Use the Personal tab above to calculate and get a color-coded health score.
What is billable productivity?
Billable productivity measures the percentage of paid time spent on revenue-generating work. Formula: (Billable Hours ÷ Total Paid Hours) × 100. It's the primary metric for therapists, lawyers, and consultants. For discipline-specific tools, see our therapy calculator.
Can productivity be over 100%?
Yes — if your actual output exceeds your target. For example, completing 22 out of 20 planned tasks = 110% efficiency. This is common in personal efficiency calculations and indicates you've exceeded expectations.
What is OEE in manufacturing?
OEE (Overall Equipment Effectiveness) = Availability × Performance × Quality. It's the gold standard for manufacturing productivity. A score above 85% is considered world class. Example: 90% × 95% × 99% = 84.6%.
How do I calculate productivity per employee?
Divide total output (revenue or units) by number of employees. Example: $500,000 revenue ÷ 10 employees = $50,000 per employee. Use the Labor tab with the Employees field to calculate this instantly.
What is a realistic productivity target for knowledge workers?
70–80% is realistic. Research consistently shows knowledge workers average 3–4.2 hours of true focused work per 8-hour day. The remaining time goes to meetings, context-switching, email, and administrative tasks that are necessary but not directly productive.
