Top-down quota planning is simple: take the board’s revenue target, divide by headcount, add a buffer, and hope for the best. It’s also how most companies set unachievable quotas.

Bottoms-up planning is harder but produces quotas that reps can actually hit - and that roll up to a target the business can believe in.

The Core Inputs

A bottoms-up quota model needs four inputs:

  1. Rep headcount by month - Including planned hires and expected attrition
  2. Ramp schedule - What percentage of full quota a new rep carries each month
  3. Historical attainment - What percentage of quota your team actually hits
  4. Territory capacity - The addressable opportunity in each rep’s territory

Step 1: Build the Headcount Plan

Create a month-by-month headcount grid:

Month Starting Reps New Hires Attrition Ending Reps
Jan 20 2 0 22
Feb 22 1 1 22
Mar 22 3 0 25

Step 2: Apply Ramp Schedules

New hires don’t produce at full capacity immediately. A typical ramp schedule:

  • Month 1: 25% of full quota
  • Month 2: 50% of full quota
  • Month 3: 75% of full quota
  • Month 4+: 100% of full quota

Calculate ramped capacity for each rep based on their start date.

Step 3: Factor in Historical Attainment

If your team historically attains 85% of quota, your model needs to account for that. There are two approaches:

  1. Gross up quotas - Set quotas 15-18% above the revenue target
  2. Plan to the median - Set quotas that the median rep can achieve, and let top performers create upside

Approach 2 is healthier for culture and retention. Unachievable quotas drive your best reps to competitors.

Step 4: Validate Against Territory Capacity

Each rep’s quota should be achievable given the opportunity in their territory. Compare:

  • Quota assigned vs. pipeline generated in the last 4 quarters
  • Quota assigned vs. total addressable market in the territory
  • Win rate × pipeline should exceed quota by at least 1.5x

If a territory can’t support the quota, either reduce the quota or redesign the territory.

Key Takeaways

  • Bottoms-up planning produces achievable, defensible quotas
  • Always account for ramp - ignoring it inflates capacity by 15-25%
  • Validate quotas against territory data, not just headcount math
  • Revisit assumptions quarterly as actuals come in
