Commission Formulas

Flat rate: Commission = Sales × Rate%

Split commission: Agent commission = Total commission × Agent split%

Tiered: Apply different rates to sales within each threshold range, then sum.

Example: Real Estate Commission

Home sold for $450,000 | Total commission: 5% | Buyer's agent split: 2.5% | Listing agent split: 2.5%

• Total commission: $450,000 × 5% = $22,500
• Listing agent: $22,500 × 50% = $11,250
• Buyer's agent: $11,250
• If listing agent splits 70/30 with broker: Agent gets $7,875

Example: Tiered Sales Commission

Sales: $120,000 | Tiers: 0–$50k = 5%, $50k–$100k = 7%, over $100k = 10%

• $50,000 × 5% = $2,500
• $50,000 × 7% = $3,500
• $20,000 × 10% = $2,000
• Total commission: $8,000 (6.67% effective rate)

Common Mistakes to Avoid

• Forgetting taxes on commission income — Commission is ordinary income. Large commission checks are often under-withheld. Set aside 25%–35% for federal and state taxes.
• Not understanding clawback provisions — Some employers "clawback" commissions if a deal cancels or a customer churns within a certain period. Know your plan's terms.
• Negotiating base salary over commission rate — In high-volume sales roles, a 0.5% higher commission rate is often worth far more than a $5,000 salary increase.

Frequently Asked Questions

What is the average real estate commission?

Traditionally 5%–6% of the sales price split between buyer's and listing agents. Following recent NAR settlement (2024), buyer's agent compensation is now negotiated separately, potentially reducing total commissions.

How is commission taxed?

Commission income is subject to federal income tax (based on your bracket), state income tax, and FICA (Social Security + Medicare). Employers may withhold at the supplemental wage rate (22% federal flat) on commission payments.

What is a draw against commission?

A guaranteed advance payment against future commissions. Recoverable draw: must be paid back if commission earned is less. Non-recoverable draw: essentially a minimum salary guarantee.

Conclusion

Commission-based income rewards performance directly — but requires careful planning for taxes and income variability. Use this calculator to project earnings across different sales scenarios and plan your budget accordingly.
