Sales Commission Calculator

How it is calculated

The tool applies a flat percentage to a base amount and shows what is left. The commission is commission = amount × rate / 100 and the remainder is net = amount − commission. Here amount is the sale or deal value in your currency and rate is the commission percentage (7.5 means 7.5%, not 0.075). The result is the commission on the whole amount at a single rate; tiered or progressive schemes, where the percentage changes above certain targets, must be calculated slice by slice. Negative amounts or rates return no result. The tool does not add or remove VAT or income tax, so check whether the amount you enter is gross or net of tax first.

Common mistakes

• Typing 0.075 instead of 7.5 for the rate, which gives a commission 100 times too small.
• Applying the rate to the wrong base, such as a price that already includes VAT when the contract is on the net price.
• Treating the net figure as the commission-earner's income; here net is what remains for the seller after paying the commission.
• Using a single rate for a tiered scheme where higher sales earn a higher percentage only on the part above the threshold.
• Forgetting that income tax on the commission is not deducted.
