How to Calculate Sales Commission
The standard sales commission formula depends on the specific compensation structure established by the company.
1. Flat-Rate Commission Formula
A fixed percentage earned on total gross sales volume.
Commission Pay = Total Sales Amount × Commission Rate (%)
Total Earnings = Base Salary + Commission Pay
2. Tiered (Graduated) Commission Formula
The commission rate increases as higher sales thresholds (quotas) are met, rewarding top performers with higher payout rates on volume exceeding baseline targets.
Total Commission = (Tier 1 Sales × Rate 1) + (Tier 2 Sales × Rate 2) + ...
Step-by-Step Calculation Examples
Let’s compare how a flat-rate plan differs from a tiered commission plan for a sales representative generating $150,000 in monthly sales with a $4,000 monthly base salary.
Scenario A: Flat 8% Commission Rate
Commission Pay = $150,000 × 0.08 = $12,000
Total Monthly Pay = $4,000 (Base) + $12,000 (Commission) = $16,000
Scenario B: Tiered Commission Rate
- Tier 1 ($0 to $50,000): 5% Commission
- Tier 2 ($50,001 to $100,000): 8% Commission
- Tier 3 ($100,001+): 12% Commission (Accelerator Tier)
| Sales Tier | Sales Volume in Tier | Tier Rate | Tier Payout |
|---|---|---|---|
| Tier 1 ($0 – $50k) | $50,000 | 5% | $2,500 |
| Tier 2 ($50k – $100k) | $50,000 | 8% | $4,000 |
| Tier 3 ($100k+) | $50,000 | 12% | $6,000 |
| Total Tiered Commission | $12,500 | ||
Under the tiered plan, the sales rep earns $12,500 in commission ($500 more than the flat plan) because the 12% accelerator rate rewarded them for pushing past $100k.
4 Popular Sales Commission Structures
Choose the commission model that aligns best with your company’s sales cycle:
- Revenue-Based Commission: Reps earn a percentage of total contract dollar value sold. Standard for high-growth software and B2C sales.
- Gross Margin Commission: Reps earn a percentage of the profit margin generated by the sale rather than top-line revenue. Prevents sales reps from giving huge unauthorized discounts to close deals.
- Base Salary + Commission: A balanced model providing financial security through a base salary alongside incentive-based commission pay.
- Straight Commission (100% Variable): The rep receives zero base salary and relies 100% on commission earned. Common for real estate agents and independent sales reps.
Frequently Asked Questions (FAQ)
What is a “Draw Against Commission”?
A draw is an advance payment made to a sales rep against their expected future commissions. A recoverable draw acts as a loan that must be paid back out of future commission checks if the rep misses quota. A non-recoverable draw is a guaranteed minimum payment during early onboarding months.
What does OTE (On-Target Earnings) mean?
OTE represents the total annual compensation a sales rep can expect to earn if they hit 100% of their assigned sales quota. It includes both base salary and on-target commission payouts (e.g., $60k Base + $60k Commission = $120k OTE).
What is a commission cap?
A commission cap puts a maximum limit on the total commission dollars a rep can earn in a given period. Most modern sales organizations avoid capping commissions, as caps discourage top performers from closing additional deals after hitting their limit.
