How It Works

The formula is: Commission = Sales Amount × (Commission Rate ÷ 100). Total Compensation = Base Salary + Commission. As a worked example: if you sell $50,000 worth of goods at a 5% commission rate with a $2,000 base, commission = $50,000 × 0.05 = $2,500, and total compensation = $2,000 + $2,500 = $4,500. The commission rate is divided by 100 to convert the percentage to a decimal before multiplication. If no base salary is entered (or it is left at 0), total compensation equals the commission alone. This model assumes a flat commission rate applied uniformly to all sales — tiered structures where the rate increases after hitting a quota threshold require calculating each tier separately and summing the results.

Examples

Real Estate Sale
Selling a $400,000 house with a 3% agent commission and no base salary.
Result: Calculates exactly $12,000 in commission earned.
Retail with Base Pay
A base salary of $2,000 plus a 5% commission on $10,000 of merchandise sold.
Result: Shows $500 in commission for a total monthly compensation of $2,500.
Software Sales Rep
An account executive closing $120,000 in software deals at 8% commission with a $5,000 monthly base.
Result: $9,600 commission + $5,000 base = $14,600 total compensation.

Frequently Asked Questions

Are commission earnings taxed?
Yes — in the United States, commission earnings are considered supplemental income and are subject to federal income tax, Social Security, and Medicare (FICA). Employers may withhold at a flat supplemental rate of 22% for federal tax, or aggregate commissions with regular wages and withhold at the standard rate. State income taxes also apply depending on where you work.
Can I use this for tiered commissions?
This calculator uses a single flat percentage rate applied to the entire sales amount. For tiered structures — where the rate increases after hitting certain thresholds — calculate each bracket separately and add the results. For example, if you earn 4% on the first $50,000 and 7% on sales above that, calculate $50,000 × 4% = $2,000 and the excess × 7%, then sum them.
What is base plus commission?
Base plus commission is a compensation model where an employee receives a guaranteed fixed salary regardless of sales performance, plus a percentage of the sales they generate. The base provides income stability while the commission component creates performance incentive. This hybrid model is common in insurance, financial services, and technology sales, where deals have long sales cycles that make pure commission risky for the employee.
