Work out how many sales reps are needed to hit a revenue target at a given quota and attainment rate.
Rated capacity is a ceiling, not a design point, so it is derated by the headroom percentage before dividing. The result is rounded up because you cannot deploy a fraction of a rep. Sizing to rated capacity leaves nothing for peaks or failures; the spare-capacity line shows whether the rounded-up count actually buys useful sales capacity.

Units = ⌈demand ÷ (capacity per unit × (1 − headroom))⌉
Units = ⌈demand ÷ (capacity per unit × (1 − headroom))⌉ Rated capacity is a ceiling, not a design point, so it is derated by the headroom percentage before dividing. The result is rounded up because you cannot deploy a fraction of a rep.

This calculator takes 3 inputs: Revenue target for the period, Quota per fully ramped rep, Headroom reserved for peaks. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
