How Sales Commission Is Calculated
Commission is commonly calculated by applying a percentage to eligible sales, but plans can include tiers and thresholds.
How the math works
A commission is a percentage applied to eligible sales, but 'eligible' is the part that varies most — some structures apply the rate to gross sales, others only after returns, discounts, or a base quota are subtracted.
Worked example
On $40,000 in monthly sales at a flat 8% commission, that's $3,200. A tiered structure that pays 5% up to $30,000 and 10% above that would instead pay $1,500 + $1,000 = $2,500 — a different result for the same total sales.
What to watch for
- Flat-rate and tiered commission structures can produce very different payouts for the same sales total
- Clawbacks on returned or cancelled sales can reduce a commission already calculated as paid
- A draw against future commission is a loan, not extra income, until it's earned back
Practical takeaway
Before estimating your commission, confirm exactly which sales count, whether the structure is flat or tiered, and whether returns can claw back a prior payout.
