What Is Commission?

Commission is pay calculated as a percentage of the sales a person makes or the value of the transactions they handle. It is common in sales, real estate, recruiting, and affiliate marketing. With a flat rate the same percentage applies to all sales; with a tiered plan each band of sales earns its own rate.

Flat Commission

Commission = sales × rate. Sales of 25,000 at 6% earn 1,500.

Tiered Commission

Each rate applies only to sales within its tier. With 5% up to 10,000 and 8% above, sales of 15,000 earn 10,000 × 5% + 5,000 × 8% = 900, an effective rate of 6%.
