Sales Team Capacity Planner

The core formula is: reps needed = revenue target / capacity per rep. Capacity per rep = (working days / sales cycle) x win rate x average deal size. You then adjust upward to account for ramp time (new hires producing below quota for their first few months) and attrition (losing productive reps throughout the year).

Average voluntary turnover in B2B SaaS sales is 25-35% per year. High-pressure environments or below-market OTE can push this to 40%. When building your hiring plan, use your actual trailing 12-month data - not an industry average - because attrition is one of the most impactful variables in capacity planning.

A new rep typically generates 40-60% of a fully ramped rep's output during their ramp period. This means you need to hire more people than a simple headcount formula suggests. For a 6-month ramp, you effectively get 0.5 productive rep-equivalents per hire during that window, which can create significant revenue gaps if you hire too late.

Airspeed analyses new rep calls in real time and surfaces coaching nudges based on what top performers do differently. New hires get feedback after every call - on talk ratio, question quality, objection handling, and next-step setting - without waiting for a manager review. This compressed feedback loop is what drives the 40% faster ramp.

Win rate and average deal size have the highest leverage - a 5% improvement in win rate has roughly the same impact as adding a full-time rep. Sales cycle length determines pipeline velocity and how quickly you can correct a miss. Team size and ramp time determine how far ahead you need to hire to avoid revenue gaps.
