Productivity Calculator 2026 | Output Per Hour & OT Cost

Question 1

How do you calculate labor productivity?

Accepted Answer

Divide total output by total hours worked. If a team produces 400 units across 48 hours, productivity is 8.33 units per hour. The measure only means something if the hours are honest, which is why productivity work and time tracking have to share the same data: unrecorded minutes inflate productivity, and padded hours deflate it.

Question 2

What is the real cost of an overtime hour?

Accepted Answer

More than 1.5 times the wage. An overtime hour costs the time-and-a-half wage plus employer payroll taxes on the premium, and it usually produces less output than a regular hour because of fatigue. If overtime hours run at 85% of normal pace, you are paying 150% of the rate for 85% of the output — an effective cost per unit roughly 76% higher than a regular hour.

Question 3

How much does productivity drop during overtime?

Accepted Answer

Research on extended schedules consistently finds output per hour falls once weekly hours pass about 50, with error and injury rates rising alongside. The drop is gradual at first and steep after several consecutive weeks. The efficiency field above lets you model your own assumption rather than accepting a generic number — track output for two overtime weeks and use your actual figure.

Question 4

Is it cheaper to pay overtime or hire another worker?

Accepted Answer

Overtime is cheaper for short, unpredictable spikes because a new hire carries recruiting, onboarding, benefits, and idle-time costs. A new worker wins when the extra demand is sustained: compare the blended cost per unit here against the fully loaded cost of an additional employee, including benefits at roughly 30% of wages. When overtime is running every week for a quarter, it has stopped being a spike.

Question 5

What is a good labor cost percentage of revenue?

Accepted Answer

It varies sharply by industry: restaurants typically target 25–35%, retail 10–20%, manufacturing 15–30%, and professional services can exceed 50%. Compare against your own trend rather than a benchmark. A rising labor share while output per hour is flat is the signal that overtime is buying hours instead of results.

Question 6

Does paying overtime reduce productivity per hour?

Accepted Answer

The pay rate does not change output, but the hours behind it do. Long weeks produce fatigue, more rework, and more absence, so output per hour tends to fall in the sixth and seventh consecutive overtime week even when workers want the money. Rotating overtime across a larger group usually preserves output better than concentrating it on a few people.

Question 7

How do I measure productivity for knowledge work?

Accepted Answer

Pick a countable unit of completed work — tickets closed, claims processed, invoices posted, deals signed — rather than activity like hours logged or messages sent. Then hold the definition steady for at least a quarter. Changing the unit mid-measurement is the most common reason productivity dashboards stop being believed.

Question 8

Should overtime hours be included in productivity metrics?

Accepted Answer

Yes, and separately. Report total output per hour for the true picture, then break out regular versus overtime hours so you can see whether the extra hours are earning their premium. Excluding overtime hours makes a stretched team look efficient right up to the point people start leaving.
