Commission Calculator
Commission is the percentage of a sale paid to the person or organisation who facilitated or closed that transaction. It is the primary compensation structure for sales professionals, real estate agents, mortgage brokers, financial advisers, and affiliate marketers. Understanding how commission is calculated — and what each party receives after commission is deducted — is essential for anyone working in or managing a commission-based environment.
Enter the total sales amount and the commission rate. The calculator shows the commission earned and the net amount — what remains after commission is deducted. For example, a real estate agent earning 6% on a £350,000 sale earns £21,000, and the seller receives £329,000 net of commission. The same arithmetic applies to wholesale transactions, franchise royalties, payment processor fees, and any situation where a percentage is deducted from a transaction value.
Commission structures vary considerably across industries and roles. Flat-rate commission (as calculated here) is the simplest structure. Tiered commissions pay an increasing rate once a volume target is reached, rewarding high performers disproportionately. Split commissions divide the fee between multiple parties, such as a listing agent and a buyer's agent in real estate. Gross profit commissions pay a percentage of margin rather than revenue, aligning the salesperson's incentive more closely with business profitability.
Formula
Commission = Sales Amount × (Commission Rate ÷ 100) Net Amount = Sales Amount − Commission
Multiply the total sales amount by the commission rate to find the commission earned. The net amount is what remains after the commission is paid.

Frequently Asked Questions
What is a typical sales commission rate?▾
Commission rates vary significantly by industry. Real estate agents typically earn 3–6% (often split between listing and buying agent). SaaS sales representatives earn 8–15%. Retail salespeople receive 1–5%. Affiliate marketers earn 5–30% depending on product margin and program. Financial advisers may earn 0.5–2% on assets or a flat fee. Rates are generally higher for complex, high-value, or long-cycle sales.
How do tiered commissions work?▾
Tiered commission structures increase the rate as sales volume grows. For example: 5% on the first £50,000 in sales, then 8% on sales above that threshold. Calculate each tier separately and add the results: for £75,000 in sales, the commission is (£50,000 × 5%) + (£25,000 × 8%) = £2,500 + £2,000 = £4,500. This calculator uses a flat rate — for tiered structures, calculate each tier separately.
Is commission calculated on revenue or profit?▾
Most commissions are calculated on gross revenue — the total sale amount. Some businesses calculate commission on gross profit instead, which directly incentivises salespeople to protect margin and avoid unnecessary discounting. Commission on margin is more complex to administer but tends to produce better pricing discipline. Always clarify the commission base in any employment or contract agreement.
What is the difference between commission and markup?▾
Commission is a percentage paid to a third party (salesperson, agent, intermediary) as compensation for facilitating a sale. Markup is the percentage added to the cost of a product to set the selling price. They are completely different concepts: commission is a payment for services; markup is a pricing method. Both are calculated as percentages of a transaction, but they serve entirely different purposes.
How do tiered commissions affect my total calculation?▾
For tiered structures, you must calculate each tier separately. If the rate is 5% on the first £50,000 and 8% on sales above £50,000, a £75,000 sale earns: (£50,000 × 0.05) + (£25,000 × 0.08) = £2,500 + £2,000 = £4,500. This is different from applying 8% to the entire £75,000, which would give £6,000. Use this calculator for each tier and sum the results.
How is commission income taxed?▾
Commission income is taxable income in most jurisdictions, treated the same as regular earnings. For employees, commission is usually included in payroll and taxed via PAYE (UK) or income tax withholding (US). For self-employed individuals and freelancers, commission is reported as business income and subject to income tax and National Insurance or self-employment tax. Consult a tax professional for advice specific to your situation.
