How Commission Works
A commission is a percentage of a sale price paid to the person who facilitated the sale β an agent, salesperson, broker, or advertiser. The fundamental formula is:
Commission = Sale Price Γ Commission Rate
For multiple sales: Commission = Total Sales Γ Rate. Commission can also be fixed (a flat fee regardless of sale price), but percentage-based structures dominate because they scale incentives with value.
Common commission structures
- Straight commission β 100% of earnings come from commission. High risk, high reward.
- Base + commission β a guaranteed salary plus a commission on top. Most common in B2B sales.
- Tiered commission β the rate increases as sales volume grows. Rewards top performers disproportionately.
- Draw against commission β an advance on future commissions, repaid out of earned commission.
- Residual commission β ongoing payments for recurring contracts (common in insurance and SaaS).
