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.

How we calculated this

We take the annual salary, scale it to the ramp period (weeks divided by 52), then multiply by the share of full output the person did not deliver over that window (100% minus the average productivity you entered). The result is salary paid for output not yet received: the cost of the ramp, per hire. We also show what halving the ramp period would save, because that is the figure a better onboarding program gets measured against. It is a salary-based proxy, so it understates roles where output is worth far more than pay. The working, the assumptions and the sources follow below.

Assumptions

Salary stands in for the value of full output. For revenue-generating and specialist roles, output is worth more than salary and the true ramp cost is higher; the cost of skills shortage calculator uses output per role instead.
Average productivity is a single figure across the whole ramp, from a slow first week to near-full output at the end. The 50% default assumes a roughly straight climb. If your new hires start higher (an internal move, say) the cost is lower; if they contribute little for the first month, it is higher.
The 12-week default is a middle-ground starting point. Ramp length is role-dependent and commonly runs three to six months for technical and senior roles, and Gallup puts peak performance potential at around 12 months. Set the weeks to what you actually see and the number moves a lot.
On-costs (super, leave, payroll tax, workers compensation) are excluded, so the salary base is conservative. Add roughly 25% to 40% for mandatory on-costs if you want the fully loaded figure.
The manager's and the team's time covering the gap is not counted here; the cost of onboarding calculator adds it.

What to do about it

The ramp period is a variable your onboarding design controls. Most organisations have never measured it, so they cannot manage it, and the money leaks quietly out of every start date. These steps are for whoever designs the first ninety days, whether they sit in HR or learning and development (L&D), or manage the new hire directly.

Measure the real ramp before you try to shorten it

For the last ten hires in the role, record the start date and the date the manager would say the person was carrying a full load. The gap in weeks, and the spread between hires, is your baseline. Most people are surprised by both.

Where a tool helps

Define full productivity as observable outcomes, per role

"Handles a full caseload", "closes a ticket without review", "signs off a quote unsupervised", "runs the weekly report alone". Until that is written down, ramp is whatever the manager feels, and feelings run long. The list also gives you the productivity curve this calculator asks for.

Front-load the capability that gates everything else

Look at the outcomes list and find the two or four things a new hire cannot do anything useful without. Teach and assess those in the first fortnight, before the culture deck and the systems tour. Sequencing alone shortens most ramps.

Give the manager a checkpoint schedule with dates in it

Week one, week four, week eight, week twelve: what should be observable by then, and what happens if it is not. Gallup's onboarding research puts manager involvement at the centre of whether a new hire calls the process a success, and involvement that is not scheduled tends not to happen.

Report weeks to full productivity next to time to hire

Recruiters are measured on filling the seat; nobody is measured on the seat becoming useful. Add the ramp figure to the hiring dashboard, by role and by manager, and re-run this calculator each quarter with the measured weeks. The saving line under the result becomes money you can point at.

Step 2 needs a map
of what capable means.

Compono Develop is a learning management system (LMS) built around what each role needs people to be capable of, so the outcomes list in step 2 becomes the structure of the first weeks rather than a document nobody opens. It runs the courses and inductions you expect and adds what most LMSs skip: capability by role, sequenced, assessed on the job and signed off with a date.

That gives you step 2 written once and used for every hire, and step 5's weeks-to-capable figure recorded as a by-product. The ramp cost above is salary paid while someone learns the role by osmosis. Develop replaces the osmosis.

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.
