Free sales commission calculator. Calculate your commission from flat rate, tiered, or quota attainment structures. Includes deductions, visual charts, and CSV export. Accurate results for real estate, SaaS, B2B, and retail sales professionals.
Determine your commission structure — flat rate, tiered, or base + commission
Gather your sales data — total sales amount or individual transaction values
Identify your commission rate(s) — check your employment agreement or comp plan
Apply the commission formula — multiply sales by rate(s) according to your structure
Account for any deductions — subtract broker fees, processing fees, or clawbacks
Add base salary if applicable — combine fixed and variable pay for total compensation
The commission formula depends on your compensation structure. A simple flat rate multiplies your total sales by a single percentage. Tiered structures apply different rates to different portions of your sales, rewarding higher volumes. Quota-based plans add accelerators that increase your rate when you exceed targets. Always subtract any deductions to arrive at your net commission.

A real estate agent sells a house for $500,000 at a 3% commission rate. Commission = $500,000 × 3% = $15,000. If the agent has a base salary of $0 (straight commission), their total compensation is $15,000.
A SaaS sales rep closes $200,000 in annual recurring revenue with 3 tiers: 5% on the first $50,000 = $2,500, 8% on the next $100,000 = $8,000, and 12% on everything above $150,000 = $6,000. Total commission = $2,500 + $8,000 + $6,000 = $16,500. With a $65,000 base salary, total comp = $81,500.
An AE has an $80,000 annual quota, a 10% commission rate, and a 1.5x accelerator above quota. They close $100,000 in sales. Regular commission on $80,000 at 10% = $8,000. Accelerated commission on $20,000 above quota at 15% (10% × 1.5) = $3,000. Total commission = $11,000. With a $55,000 base, total comp = $66,000.

A sales commission is a performance-based payment that compensates salespeople based on the volume or value of sales they generate. It serves as a powerful incentive to drive higher revenue and rewards top performers with additional earnings beyond any base salary. Commission structures are widely used across real estate, retail, B2B sales, SaaS, financial services, and insurance industries. The more you sell, the more you earn — making it a key motivator for sales-focused roles.
Commission rates vary significantly by industry: Real estate agents typically earn 2–6% of the sale price. SaaS and software sales reps often see 5–15% on annual recurring revenue. Retail sales associates usually earn 1–5% of sales. Insurance agents can earn 10–25% on new premiums. B2B sales professionals generally earn 5–10% of deal value. The exact rate depends on deal size, product complexity, sales cycle length, and the balance between base salary and variable compensation.
Tiered commission structures apply progressively higher rates as your sales volume increases through predefined thresholds. Each tier only applies to the sales within its specific range — this is called marginal calculation. For example, the first $50,000 might earn 5%, the next $50,000 earns 8%, and everything above $100,000 earns 12%. This approach rewards higher performance with proportionally greater earnings and motivates salespeople to push beyond minimum targets for maximum earning potential.
A commission accelerator increases your commission rate when you exceed your sales quota. For example, if your base rate is 10% and your accelerator is 1.5x, any sales above your quota earn 15% instead of 10%. Accelerators are especially common in SaaS and B2B sales where exceeding targets significantly impacts company growth. They create a strong financial incentive to push past 100% quota attainment, often resulting in exponential earnings growth for top performers.
Commission income is generally taxed as ordinary income at the federal level, just like regular salary. However, employers often withhold taxes at a higher supplemental rate — typically 22% federal flat rate — on commission payments, which means larger deductions from each commission paycheck. This does not mean you pay more in total taxes, the difference is usually reconciled when you file your annual return. Self-employed individuals must also pay self-employment tax (15.3%) and make quarterly estimated payments. State and local taxes vary by jurisdiction.
Gross commission is the total commission earned before any deductions are subtracted. Net commission is what you actually take home after broker fees, agency splits, processing fees, clawbacks, and other deductions have been applied. This distinction is especially important in real estate, where agents may split their commission with their brokerage (e.g., a 70/30 split), and in insurance, where premium financing and processing costs can reduce actual earnings significantly.
Yes, many employers include clawback provisions in their commission agreements. Common triggers include customer cancellations, product returns, failed payments, or early contract terminations that occur within a specified period after the sale. Some companies also claw back commissions if you leave the company before a certain vesting period. It is critical to review your employment agreement or compensation plan carefully to understand the specific clawback terms, timelines, and conditions that apply to your commission.
When a sale is returned or cancelled, the commission previously earned on that sale is typically clawed back in full. For example, if you earned $500 commission on a $10,000 sale that is later returned, your employer will deduct $500 from future commissions. For partial returns, the clawback is pro-rata — a 50% return means a 50% clawback of the original commission. In tiered structures, a return can be particularly complex because it may shift your total sales into a lower tier, retroactively reducing the rate applied to your remaining sales. Always check your comp plan for the specific return policy.
