Period-by-period detail

Rep capacity and attrition ledger

The ledger converts ramping hires to effective rep capacity, applies quota attainment, isolates annualized attrition drag, and reconciles net revenue capacity.

How to use Sales Capacity Planning Calculator

  1. Enter fully ramped and ramping representative counts.
  2. Estimate average ramp productivity for the planning period.
  3. Apply a realistic attainment rate to gross quota capacity.
  4. Deduct attrition capacity and compare net capacity with the revenue plan.

Calculator guide

Understanding Sales Capacity Planning Calculator

Sales capacity planning translates named representatives into productivity-adjusted selling capacity. Ramping representatives, expected attainment, and attrition are distinct deductions, so headcount alone does not describe attainable revenue.

Headcount is not capacity Ramping reps contribute only part of a full rep.
Attainment is a separate haircut Quota assignment and achieved revenue differ.
Attrition removes productive time Departures reduce capacity before replacements ramp.
Dependencies matter Leads, territories, and management can constrain output.

Calculation method

How the calculation works

Convert ramping representatives into effective capacity, apply expected attainment, and separately deduct an annualized attrition capacity loss. New representatives are multiplied by their average productivity and added to fully ramped representatives. Effective reps times annual quota gives gross quota capacity; attainment is applied before the annualized capacity loss from attrition is deducted.

Hiring decision

Separate capacity creation from hiring volume

A hiring plan should explain when capacity becomes productive and what enables it.

Recruit Named start dates and hiring confidence.
Ramp Monthly productivity curve by cohort.
Enable Manager, territory, and pipeline support.
Retain Expected departures and backfill delay.

Worked situations

Practical examples

  • Six new reps at 45% productivity add only 2.7 effective reps.
  • An 82% attainment assumption reduces gross quota capacity before attrition.
  • Hiring more representatives may not close a gap if ramp time extends beyond the plan.

Better inputs

Useful tips

  • Model start dates by cohort when hiring is uneven.
  • Use quota attainment from comparable territories and tenures.
  • Check manager, lead, and territory capacity before adding headcount.

Before relying on the result

Limitations and common mistakes

  • The model uses an average ramp productivity instead of a monthly cohort curve.
  • Attrition loss is annualized and does not schedule replacement timing.
  • Territory quality, lead supply, seasonality, vacancies, and over-assignment are excluded.

Reference

Key terms

Effective reps
Fully ramped reps plus productivity-adjusted new reps.
Quota capacity
Effective reps multiplied by quota.
Attainment
Expected share of assigned quota achieved.
Attrition loss
Annualized revenue capacity removed by expected departures.

Frequently asked questions

Why use effective reps?

It prevents a newly hired representative from being counted as fully productive immediately.

Is quota capacity the same as forecast revenue?

No. Attainment and attrition reduce theoretical quota capacity.

How should new-rep productivity be estimated?

Use the average productive share expected during the planning period from historical ramp cohorts.

Does attrition include new reps?

This simplified formula applies attrition to fully ramped reps; a cohort schedule is needed for more detail.
