How It Works
How This Commission Calculator Works
This tool supports five distinct commission structures. Each uses a specific formula. All currency values are rounded to two decimal places.
Choose from straight, tiered, draw-against, split, or residual. The form adapts to show only the fields you need.
Input your sales amount, rate, draw advance, split percentage, or account data depending on your structure.
Enable the federal withholding estimate to see the 22% supplemental rate plus FICA deducted from your gross commission.
The results show your gross commission, tier-by-tier detail, estimated taxes, and net take-home in one clear view.
For pay period breakdowns like weekly or biweekly commission pay, use the paycheck calculator for a full withholding estimate. To compare a salary-only role with a commission-based offer, use the salary calculator.
Key Information
How Commission Income Is Taxed in 2026
Federal Supplemental Withholding Rate
The IRS classifies commission paid separately from regular wages as supplemental wages. Employers withhold federal income tax at a flat 22% rate on supplemental wages up to $1,000,000 paid to one employee in a year. Amounts above $1,000,000 in a single year are withheld at 37%.
FICA Taxes on Commission
Social Security tax applies at 6.2% on commission income up to the 2026 wage base of $176,100. Medicare tax applies at 1.45% on all commission income with no cap. An additional 0.9% Medicare surtax applies to wages over $200,000 (single) or $250,000 (married filing jointly), but employer withholding for that surtax only begins after $200,000 per employee.
Straight Commission Formula
Gross commission = Total sales × Commission rate. Example: $60,000 in sales at 5% = $3,000 gross commission. If you also have a base salary, your total gross pay is the base plus the commission. Use the gross pay calculator to include both in one figure.
Tiered Commission Formula
Each tier rate applies only to sales within that tier's range. If Tier 1 covers $0 to $25,000 at 4%, and Tier 2 covers $25,001 to $50,000 at 6%, then $40,000 in sales earns ($25,000 × 4%) + ($15,000 × 6%) = $1,000 + $900 = $1,900 total commission. Rates do not apply retroactively to all sales.
Draw Against Commission
A draw is an advance on future earnings. With a recoverable draw: net payment = gross commission minus draw paid. If gross commission exceeds the draw, you receive the difference. If commission falls short of a recoverable draw, the deficit rolls to the next period. With a non-recoverable draw, the draw acts as a guaranteed minimum and any shortfall is forgiven.
Residual Commission Formula
Monthly residual = Active accounts × Revenue per account × Commission rate. For annual projection, multiply monthly residual by 12. Residual income is reported on W-2 for employees or 1099-NEC for independent contractors. Contractors also owe self-employment tax. See the self-employment tax calculator if you are a 1099 rep.

FAQ
Commission Calculator Questions Answered
The most common method is straight commission: multiply your total sales by your commission rate. For example, $50,000 in sales at a 5% rate equals $2,500 in commission. Tiered structures apply different rates to different sales ranges. This calculator supports all major commission structures used by US employers in 2026.
Commission paid separately from regular wages is classified as supplemental wages by the IRS. When paid separately, employers typically withhold federal income tax at the 22% flat supplemental rate (for amounts under $1,000,000) or aggregate it with your regular pay. Social Security and Medicare taxes apply at the same rates as regular wages. State withholding varies by state.
A draw against commission is an advance your employer pays you before commissions are earned. If you earn $3,000 in commission but received a $2,000 draw, your net payment is $1,000. Some draws are non-recoverable, meaning you keep the draw even if commissions fall short. Others are recoverable, and any shortfall is deducted from future earnings.
A tiered structure pays different commission rates based on sales volume thresholds. For example, you might earn 4% on the first $25,000 in sales, 6% on the next $25,000, and 8% on everything above $50,000. Each tier applies only to the sales within that range, not retroactively to all sales.
Split commission occurs when the total commission on a sale is divided between two or more reps, such as an inside sales rep and a field rep. If the deal earns $2,000 in commission and it is split 60/40, rep A gets $1,200 and rep B gets $800. Enter your share percentage in this calculator to find your portion.
The tax estimate uses the 2026 federal supplemental withholding rate of 22% plus FICA (Social Security at 6.2% up to the $176,100 wage base and Medicare at 1.45%). State income tax on commissions varies widely by state and is not included in this calculator. Use the paycheck calculator for a full state-by-state estimate.
Residual commission is recurring income paid for each period a customer continues to use a product or service you originally sold. It is common in insurance, SaaS, and subscription-based sales. Your monthly residual equals the number of active accounts multiplied by the revenue per account multiplied by your commission rate.
