How to Calculate Sales Commission
Commission is the variable compensation paid to salespeople as a percentage of the sales they generate. The basic formula is:
Commission = Sales Amount × Commission Rate
For total earnings with a base salary:
Total Earnings = Base Salary + Commission
Example: A real estate agent sells a $400,000 home at a 3% commission rate on their side of the transaction:
Commission = $400,000 × 0.03 = $12,000
If they also earn a $2,000/month base salary:
Total = $2,000 + $12,000 = $14,000 for the month
Types of Commission Structures
Different industries use different commission models, each with distinct advantages and tradeoffs:
| Structure | How It Works | Best For |
|---|---|---|
| Flat/Straight Commission | Fixed % of all sales with no base salary. 100% variable pay. | Real estate agents, independent contractors, high-upside roles |
| Base + Commission | Fixed monthly salary + % commission on sales. Most common structure. | Inside sales, SaaS, B2B sales reps |
| Tiered Commission | Rate increases after hitting sales thresholds. E.g., 5% on first $50K, 7% on $50K–$100K, 10% above $100K. | Motivating top performers, sales teams with wide performance ranges |
| Gross Margin Commission | Commission paid on profit, not revenue. Discourages excessive discounting. | B2B, distributors, wholesale |
| Draw Against Commission | Salesperson receives a guaranteed "draw" (advance) that is recovered from future commissions. | New hires, seasonal sales roles |
| Residual Commission | Ongoing commission for accounts as long as they remain customers. | Insurance, SaaS, subscription services |
| Territory Volume | Commission split equally among team members in a territory based on total territory sales. | Geographic sales teams, retail districts |
Commission Rates by Industry
Commission rates vary dramatically by industry based on deal size, sales cycle length, and competition for talent:
| Industry | Typical Commission Rate | Average Annual OTE |
|---|---|---|
| Real Estate (buyer/seller agent) | 2.5–3% per side | $50K–$150K+ |
| SaaS / Software Sales (AE) | 8–12% of ARR | $100K–$250K (OTE) |
| Insurance (life/health) | 40–120% first year, 3–10% renewal | $50K–$120K |
| Financial advisor / Wealth mgmt | 0.5–1% AUM or 3–5% per product | $60K–$200K+ |
| Pharmaceutical sales | 2–5% of sales or flat bonus | $90K–$140K (OTE) |
| Retail (auto, electronics) | 2–5% per unit or gross profit % | $30K–$80K |
| Recruiting / Staffing | 15–25% of placed candidate's salary | $50K–$150K+ |
| Mortgage broker | 0.5–2.75% of loan amount | $60K–$150K |
| Freelance / Affiliate | 5–50% depending on product | Varies widely |
Tiered Commission Calculations
Tiered commissions reward top performers with higher rates as they hit thresholds. Here is how to calculate them:
Example commission plan:
- 0–$25,000 in sales: 5% commission
- $25,001–$75,000 in sales: 7% commission
- $75,001+ in sales: 10% commission
Salesperson with $90,000 in sales:
- Tier 1: $25,000 × 5% = $1,250
- Tier 2: ($75,000 − $25,000) × 7% = $50,000 × 7% = $3,500
- Tier 3: ($90,000 − $75,000) × 10% = $15,000 × 10% = $1,500
- Total Commission: $1,250 + $3,500 + $1,500 = $6,250
- Effective Rate: $6,250 / $90,000 = 6.94%
Notice that the effective rate (6.94%) is lower than the top tier rate (10%) because the lower rates apply to the earlier sales. This is similar to how progressive income tax brackets work.
OTE, Quota, and Commission Plan Math
In B2B and SaaS sales, understanding OTE (On-Target Earnings) and quota is essential for evaluating a job offer or managing a team:
- OTE (On-Target Earnings): The total compensation (base + commission) if you hit exactly 100% of quota. A $150K OTE with a 50/50 split means $75K base + $75K target commission.
- Quota: The sales target. If your OTE is $150K (50/50) and quota is $1M ARR, you earn $75K commission at 100% quota attainment. Your commission rate = $75K / $1M = 7.5%.
- Accelerators: Commission rates above 100% quota are often accelerated. Hitting 120% quota at a 2× accelerator would pay 7.5% × 2 = 15% on the additional $200K = an extra $30K.
- Ramping: New reps often have reduced quota in their first 30–90 days ("ramp period") to account for onboarding time. A 50% ramp for Q1 means quota of $500K instead of $1M.
Commission Taxes: What You Actually Take Home
Commission income is taxed as ordinary income, but the timing and withholding can surprise new salespeople:
- Federal withholding: Employers must withhold taxes on commission payments. The "aggregate method" adds commission to your regular pay and withholds at your current tax rate. The "percentage method" (for supplemental wages) uses a flat 22% federal withholding rate for most employees.
- State taxes: Apply on top of federal taxes. States like California (up to 13.3%), New York (10.9%), and New Jersey (10.75%) significantly reduce take-home.
- Self-employed commission: If you are an independent contractor (1099), you owe self-employment tax (15.3% on the first $160,200 of net earnings) plus income tax. Plan to set aside 25–35% for taxes.
- Big commission checks: A $50,000 commission check may have 22%+ federal + state withheld, leaving $30,000–$35,000 net depending on your state. If over-withheld, you get a refund at tax time.
Tip: If you receive large irregular commission payments, consider making quarterly estimated tax payments to avoid underpayment penalties.
Frequently Asked Questions
What is a good commission rate?
A "good" commission rate depends on the industry, deal size, and sales cycle. For high-value B2B SaaS, 8–12% of ARR is typical. For real estate, 2.5–3% per side. For retail, 2–5%. The key metric is not the rate itself but the OTE (total expected earnings) relative to market and your quota attainability.
How is commission taxed?
Commission is taxed as ordinary income (same as regular wages). If paid on your W-2, employers withhold 22% federal (supplemental wage rate) plus applicable state and local taxes. If you are a 1099 contractor, you also owe 15.3% self-employment tax on net earnings. Plan to set aside 25–35% for taxes on large commission checks.
What is a draw against commission?
A draw is a regular payment advanced to a salesperson against future commissions — like a loan against anticipated earnings. If your draw is $3,000/month and you earn $5,000 commission, you receive $2,000 net (draw recovered). Draws can be "recoverable" (owed back if you leave) or "non-recoverable" (essentially a guaranteed minimum).
Can an employer change my commission structure?
Employers can change commission structures prospectively (for future sales) with proper notice. However, commissions already earned on completed sales are generally protected as wages under state law and cannot be reduced retroactively. Many states (especially California) have strong "earned commission" protections.
What is residual commission?
Residual commission is ongoing commission paid as long as a customer you brought in continues to pay. Common in insurance (renewal commissions) and SaaS (retention-based comp). A salesperson who sold a $10,000/year contract might earn 10% = $1,000 each year the client renews, building passive recurring income over time.
How do I calculate my effective commission rate?
Effective commission rate = Total commission earned ÷ Total sales. If you earned $8,500 commission on $120,000 in sales, your effective rate = $8,500 / $120,000 = 7.08%. This is useful in tiered plans where different rates apply to different tiers.
What is the difference between gross and net commission?
Gross commission is the total commission before any deductions. Net commission is what you receive after splits (e.g., with a brokerage), fees, or chargebacks. Real estate agents, for example, may earn 3% gross but split 30–50% with their broker, receiving a 1.5–2.1% net commission.
How does real estate commission work?
Real estate commission is typically 5–6% of the sale price, split between the seller's agent and buyer's agent. Each side (usually 2.5–3%) is then further split between the agent and their brokerage (often 50/50 to 70/30 in the agent's favor). On a $400,000 home: 3% = $12,000 gross to buyer's agent, of which they may keep $7,200–$8,400 after broker split.
What is an OTE in sales?
OTE (On-Target Earnings) is the total compensation you expect to earn if you hit 100% of your sales quota. It includes base salary plus target commission. A $120K OTE with a 60/40 base-to-commission split means $72K base + $48K target commission. OTE is the standard benchmark for evaluating and comparing sales comp packages.
How do I negotiate a commission plan?
Key levers: (1) quota — negotiate a lower, more attainable quota rather than a higher rate; (2) accelerators — push for 1.5–2× accelerator above 100% quota; (3) ramp period — request 60–90 day ramp with reduced quota; (4) clawback terms — negotiate shorter clawback windows (30–60 days vs 6–12 months); (5) product mix — ensure your commission applies to all products you are expected to sell, not just certain tiers.
