On these inputs the internship pays for itself inside the first year — mostly through the avoided agency fee, the shorter ramp and the lower mis-hire risk.

Break-even

Cumulative cost of the intern path falls below the lateral path in month 1. If your people typically stay longer than that, conversion pays back. If they leave sooner, it does not — on cost alone.

This model uses only the numbers you enter — there are no platform statistics inside it. Two modelling choices worth knowing: hiring effort on the intern path is halved because the internship itself did the assessment, and the mis-hire line prices a failed external hire at the re-hire cost plus roughly a third of a year’s salary. Both are visible in the rows above, so you can argue with them.

Questions employers ask

Is converting an intern actually cheaper than hiring laterally?+

Usually, but not always, and the reason is rarely the salary. A converted intern costs less on three lines: no agency fee, a much shorter ramp because they already know the codebase or the process, and a far lower probability of a mis-hire because you watched them work for three to six months. Where conversion loses is when the converted salary is set well above market to retain them, or when the internship itself was long and expensive relative to the role. The calculator prices all of that so you can see which case you are in.

What is a realistic intern-to-full-time conversion rate in India?+

It varies enormously by company type. Large IT services and GCCs running structured PPO programmes convert a high share of their intern cohort because the internship is effectively an extended assessment. Startups and mid-market companies convert far fewer, often because headcount is decided after the internship rather than before it. The honest planning rule: decide how many seats exist before the internship starts, and tell the interns. Programmes that leave conversion undefined convert worse and lose the interns they wanted.

How should I estimate ramp time?+

Ramp time is the months before someone produces at the level you are paying for. For a converted intern in the same team it is usually short — often under two months — because they already know the systems, the people and the process. For an external fresher hire it is longer. For an experienced lateral hire it is shorter than a fresher but rarely zero, because domain and codebase context still take time. Use your own observed numbers if you have them; the defaults here are conservative.

Why does this model include a "failed hire" cost?+

Because ignoring it flatters lateral hiring. A hire that does not work out costs the fee again, the salary paid in the meantime, and the time of everyone who interviewed and onboarded them. Conversion carries far less of this risk — its whole value proposition is that you already have months of evidence rather than four hours of interviews. Setting this input to zero is the single fastest way to make lateral hiring look better than it is.

What is the break-even month?+

The month at which the cumulative cost of the intern path drops below the cumulative cost of the lateral path. The intern path starts behind, because you paid a stipend for months before the person was productive. It catches up as the lateral path carries its agency fee and higher salary. If break-even lands inside your typical tenure, conversion wins; if it lands past it, it does not.

Does this model account for the intern leaving after conversion?+

Indirectly, through the break-even month. If your converted interns typically leave at eighteen months and break-even lands at month twenty-two, the model is telling you the conversion did not pay back on cost alone — you were buying something else, such as a stronger pipeline or a better employer brand on campus. Those are legitimate reasons; they just are not cost savings, and you should not present them as such internally.
