Calculate flat, tiered, or split sales commissions with tax withholding estimates.
A sales commission is a performance-based payment calculated as a percentage of the sales revenue a salesperson generates. Commission structures vary from flat-rate percentages to tiered models where higher sales volumes earn higher rates.
Gross Commission
| Industry | Typical Rate | Basis |
|---|---|---|
| Real Estate | 2.5–3% | Sale price |
| SaaS / Software Sales | 8–12% | Annual contract value |
| Car Sales | 20–25% | Gross profit |
| Insurance | 5–10% | Premium |
| Mortgage Brokers | 0.5–2.75% | Loan amount |
| Retail Sales | 1–5% | Revenue |
| Recruiting / Staffing | 15–25% | First year salary |
Formula
Commission = Sale Amount × Commission Rate | Tiered: Commission = Σ(Tier Amount × Tier Rate)Sale Amount = Total revenue generated from the sale
Commission Rate = Percentage of sales paid as commission
Tier Amount = Portion of sales within each tier range
