How to Model Sales Compensation Plans
Sales compensation plan modeling helps you design fair, motivating comp structures before rolling them out. Test different scenarios to understand earnings at various performance levels.
Common Compensation Plan Structures
Tiered Plan Design Best Practices
- Tier 1 (0-75% quota): Reduced rate (60-80% of base rate) to discourage sustained underperformance
- Tier 2 (75-100% quota): Base commission rate, standard OTE calculation
- Tier 3 (100%+ quota): Accelerated rate (1.5-2x base) to reward top performers
- Sweet Spot: 50-60% of reps should comfortably reach Tier 2/3
Key Metrics to Model
- OTE (On-Target Earnings): Total comp at 100% quota
- Earnings at 50%: What underperformers make (should still be livable)
- Earnings at 150%: What top performers can earn (should be compelling)
- Effective Commission Rate: Actual % paid at each attainment level
- Company Cost: Total comp cost as % of revenue at different levels
How to Test Your Comp Plan
- Model Historical Performance: Apply new plan to last year's results
- Calculate Rep Distribution: What % of reps land in each tier?
- Check Competitiveness: Compare OTE to market benchmarks
- Test Edge Cases: What happens at 0%, 50%, 200% attainment?
- Measure Motivation: Does the plan incentivize desired behaviors?
- Verify Affordability: Can the business sustain comp costs?
Common Plan Design Mistakes
- Too Complex: Reps can't calculate their earnings easily
- Unrealistic Quotas: Less than 40% hit target (demotivating)
- No Accelerators: No reward for exceeding quota (caps performance)
- Hard Caps: Limits earnings potential (kills motivation)
- Frequent Changes: Changing plans mid-year erodes trust
- Misaligned Incentives: Rewarding wrong behaviors (e.g., discounting)
Comp Plan Red Flags
Watch for these warning signs:
- Less than 40% of reps hitting quota (quota too high or plan broken)
- Top performers leaving (insufficient upside or comp not competitive)
- Sandbagging (reps holding deals to next period - quota/timing issue)
- Heavy discounting (commission rewards volume over margin)
- Churning customers (commission paid upfront without clawback)
