How Sales Commission Works

Sales commission is compensation earned as a percentage of the sales revenue you generate. It incentivises performance by directly linking pay to results.

Commission Formula

Commission = Sales Amount × Commission Rate / 100. If your sales exceed the bonus threshold, an additional bonus rate applies to the amount above that threshold.

Common Commission Structures

  • Flat Rate: A single percentage on all sales (e.g., 10%)
  • Tiered: Higher rates kick in after hitting quotas
  • Base + Commission: Guaranteed salary plus variable commission
  • Draw Against Commission: Advance paid against future commissions

Industry Benchmarks

Commission rates vary widely by industry: real estate agents typically earn 5–6%, SaaS sales reps 8–15%, and insurance agents 5–20%. The effective rate reflects your total commission earnings as a percentage of total sales.

Frequently Asked Questions

What is the difference between commission and bonus?
Commission is a percentage earned on every sale. A bonus is an additional percentage earned on sales exceeding a specific threshold, rewarding top performers who surpass their targets.
What is an effective commission rate?
The effective commission rate is your total commission earnings (base commission plus any bonuses) divided by your total sales, expressed as a percentage. It shows your true earning power.
How do tiered commission structures work?
In a tiered structure, you earn a base commission rate on all sales. Once you exceed a threshold (quota), a higher bonus rate applies to the amount above that threshold, incentivising you to sell more.
Should I negotiate for a higher base or higher commission?
It depends on your confidence in closing deals and your risk tolerance. A higher base offers stability, while a higher commission rewards strong performers. Use this calculator to model both scenarios.
