Commission Calculator
Estimate flat-rate or tiered sales commission, account for returns and an advance or draw, and compare commission earned with the amount payable now. This calculator is for sales compensation plans, not real-estate brokerage splits.
How the commission calculation works
First, the calculator subtracts returns or excluded transactions from gross sales. It then applies the selected compensation model.
Commissionable sales = gross sales − returns or excluded sales
Flat commission = commissionable sales × flat rate
Commission payable now = max(0, gross commission − advance)
Progressive tiers apply each rate only to the sales inside that band. Retroactive tiers apply the rate reached to all commissionable sales. Because employers use different names for these structures, confirm the rule in your compensation plan.
Checked examples
Flat-rate example
With $100,000 in gross sales, $5,000 in returns, a 5% rate, $2,000 base pay and a $1,000 advance, commissionable sales are $95,000. Gross commission is $4,750, commission payable now is $3,750, total compensation earned is $6,750, and current gross pay after the advance is $5,750.
Progressive versus retroactive tiers
For $125,000 in sales with tiers of 3% through $25,000, 5% through $50,000, 7% through $100,000 and 10% above that, progressive commission is $8,000. Under a retroactive plan, reaching the 10% tier makes the commission $12,500.
Limits and tax treatment
- This estimate excludes taxes, withholding, overtime, bonuses, quotas, accelerators, caps, chargebacks and delayed payment rules unless represented by the fields above.
- The currency selector changes formatting only; it does not perform foreign-exchange conversion.
- The IRS lists commissions among supplemental wages. Actual withholding and take-home pay depend on payroll treatment, so this tool reports gross amounts only.
- Commission earnings can affect the regular rate used for overtime under U.S. wage rules. This calculator does not determine overtime eligibility or compliance.
