What is time to productivity?

It is how long a new hire takes to reach the full output expected of the role. Until they get there, you are paying a full salary for partial value, which is the gap this calculator measures.

Where Compono fits

Knowing the cost of slow ramp-up is one thing. Closing it is another, and that depends on building capability quickly, not just running people through induction. Compono Develop structures the learning that gets new hires to full output sooner, with capability tracked along the way. Compono is built on decades of psychometric research and holds 4.8 out of 5 on Capterra.

How it's calculated

Ramp cost is the difference between a fully productive person's salary value and the new hire's actual output, summed across the ramp period. With a default ramp of 12 weeks at an average 50% productivity, a new hire produces roughly half their value over that window, and the missing half is the cost. Ramp length is role-dependent and commonly runs 3 to 6 months.

Common questions

What's a realistic ramp period?

It depends heavily on role complexity. Frontline roles can ramp in weeks, while technical or senior roles commonly take 3 to 6 months. The 12-week default here is a middle-ground starting point you should adjust to your roles.

How do I estimate average productivity during ramp?

Think about output across the whole ramp period, not the first day. Many roles average around 50% of full productivity over the ramp window, starting low and climbing. Adjust the default to match what you see in your teams.

Does faster ramp-up hurt quality?

Not when it is driven by structured capability building rather than rushing people. Clear learning and early feedback tend to improve both speed and quality, because new hires understand what good looks like sooner.
