Sales commission is a percentage of the sale price paid to the salesperson as compensation. Commission structures vary widely: some roles are 100% commission, others offer a base salary plus commission, and some use tiered rates that increase with higher sales volumes.

Common commission rates vary by industry. Real estate agents typically earn 2.5-3% per side, retail sales 1-10%, SaaS/software sales 8-15%, insurance 5-20%, and financial services 1-5%. The rate often reflects the sales cycle length and deal complexity -- longer, more complex sales tend to command higher commission rates.

When evaluating commission-based roles, consider the full compensation package: base salary, commission rate, average deal size, sales cycle length, and quota requirements. A 10% commission sounds high, but if the average deal is $5,000 and takes 3 months to close, the math may not support your income needs. Always model realistic scenarios, not best-case projections.
