The arrangement is called commission: pay calculated as a percentage of the sales you generate. An irregular income is money that changes from period to period, often because sales volume, seasons, or customer demand shift. Gross income is total earnings before taxes and deductions. Overtime is extra pay for hours beyond a threshold, usually 40 in a workweek, and it must be calculated correctly when commission is involved.
How commission actually works
Commission is a variable-pay mechanism, not a wage for time. An employer defines a sales event (a closed deal, a collected payment, a shipped order) and a rate (a percentage, a flat amount per unit, or a tiered schedule). The rate can attach to revenue, to gross profit, or to margin. That choice matters more than the percentage itself.
Revenue-based commission rewards volume. Gross-profit commission rewards profitable volume. Margin-based commission pushes the seller toward price discipline. A seller earning 10% of revenue on a USD 1,000 deal gets USD 100 regardless of whether the product cost USD 200 or USD 900 to deliver. The same seller earning 10% of gross profit gets USD 80 in the first case and USD 10 in the second.
Timing is the second mechanism. Some plans pay at booking, when the order is signed. Others pay at collection, when cash arrives. Collection-based plans transfer credit risk to the salesperson and routinely delay payout 30 to 90 days. Draws are the third mechanism: a recoverable draw is an advance against future commission that the employer recoups, while a non-recoverable draw is guaranteed money that is not clawed back.
Commission also interacts with wage law. In the United States, the Fair Labor Standards Act sets a federal minimum wage of USD 7.25 per hour and requires overtime at 1.5 times the regular rate for covered employees past 40 hours in a workweek. The regular rate is not just the hourly base: non-discretionary commissions are generally included when employers compute it. Commissions are non-discretionary when the amount and conditions are agreed in advance, such as a published rate on sales.
The math that changes your paycheck
The percentage you negotiate is only one variable. The denominator, the trigger, and the quota threshold usually move the number more.
A 5% rate on USD 200,000 of annual sales yields USD 10,000. The same 5% on gross profit, where the company runs a 30% margin, yields USD 3,000. Add a quota threshold of USD 150,000 before commission starts, and the payout on USD 200,000 is 5% of USD 50,000, or USD 2,500. Three plans, same headline rate, fourfold difference in pay.
Tiered schedules compound the effect. A common structure pays 5% up to quota, 8% from quota to 120% of quota, and 10% above that. On a USD 100,000 quota and USD 130,000 in sales, the payout is USD 5,000 plus 8% of USD 30,000, or USD 7,400. Accelerators reward overperformance; decelerators or commission caps cap it.
Overtime changes the picture for hourly-plus-commission workers. Suppose a non-exempt employee earns USD 12 per hour and also receives USD 120 in non-discretionary commission in a 50-hour week. Straight-time earnings are USD 600 plus USD 120, or USD 720. The regular rate is USD 720 divided by 50, or USD 14.40. The overtime premium is 0.5 times USD 14.40 times 10 overtime hours, or USD 72. Total pay is USD 792, not the USD 720 a simple base-rate calculation would suggest.
Gross income is the layer above all of this. Commission and overtime are gross income until taxes, benefit contributions, and garnishments come out. Net pay is what lands in the account.
Edge cases that break simple rules
Chargebacks and clawbacks reverse commission when a deal cancels, a customer defaults, or a product is returned. Many plans allow recovery for 90 to 180 days after payment. A seller can book a strong month, spend against it, and owe money back the next quarter. Read the clawback window before counting commission as income.
Split credit appears when two or more people work a deal. The plan may divide the rate, pay a reduced "house account" rate, or assign credit to one owner. Renewals and recurring revenue are another edge case: some plans pay full rate on year one and a reduced rate, often 2% to 5%, on renewals.
State wage law differs on when earned commission becomes wages. Some states treat commission as earned when the salesperson secures the order; others wait for collection or acceptance. A professional caveat worth knowing: a well-drafted plan usually includes an express "at-will" clause and the employer's right to modify the plan prospectively, but it cannot lawfully retroactively reduce commission already earned under many state statutes.
The genuinely counterintuitive detail: a higher commission percentage can lower total pay. If moving from a 6% revenue plan to a 10% gross-profit plan drops the payout base by more than 40%, the seller earns less per deal while carrying more risk. Always model total compensation, not the headline rate.
Watch for these red flags:
No written commission plan, or a plan revised without a signed acknowledgment. Clawback terms with no stated time limit or no cap on recoverable amounts. Commission paid only "at the company's discretion" with no defined trigger. Quota changes mid-period after deals are already in the pipeline. Deductions from commission for "administrative costs" not disclosed in advance. Overtime computed on base hourly pay only when commission is non-discretionary.
Misconceptions about commission, gross income, and overtime
The most common error is treating commission as net income. A USD 5,000 commission check is gross income; withholding on supplemental wages often runs in the 22% federal range for many employees, though the exact method depends on the employer and the employee's withholding elections. State and local taxes apply on top.
The second error is assuming salary and commission are interchangeable. Salary is fixed and predictable; commission is contingent. A USD 60,000 base plus USD 40,000 target commission is not the same job as a USD 100,000 salary, even if the target is hit in a normal year. Volatility, clawback exposure, and quota risk all carry a cost.
The third error is believing salaried workers never get overtime. Exempt status depends on duties and the salary threshold, not on whether pay includes commission. Some inside-sales roles are non-exempt and owed overtime even when commission is part of the package.
The fourth error is assuming overtime and commission are mutually exclusive. They are not. Non-exempt employees with non-discretionary commission must have that commission folded into the regular rate for overtime purposes.
Comparison table: common pay structures

|---|---|---|
| Sale booked | Day 0 | Commission may be "earned" in some states |
| Order fulfilled | Days to weeks | Some plans require delivery before payout |
| Customer payment collected | 30 to 90 days | Collection-based plans trigger here |
| Commission statement issued | End of pay period | Amount calculated and disclosed |
| Payout | Next regular payroll | Often 1 to 30 days after statement |
| Clawback window | 90 to 180 days | Commission can be reversed |
| Plan renewal | Annual, sometimes mid-year | Rates and quotas may reset |
Practical actions for employees and employers
Employees should request the written plan before accepting an offer. Model three scenarios: hitting quota, missing quota by 20%, and exceeding quota by 20%. Ask when commission is earned, when it is paid, and what triggers a clawback. Confirm whether the role is exempt or non-exempt and whether commission counts toward the regular rate for overtime.
Track every deal in a personal ledger with dates, amounts, trigger events, and payout expectations. Reconcile each commission statement against that ledger. If a payment is short, raise it in writing within the pay period to preserve records.
Employers should put the plan in writing and have employees sign an acknowledgment. Define the commission trigger precisely: booking, shipment, collection, or acceptance. Disclose clawback windows and caps. For non-exempt employees, include non-discretionary commission in the regular-rate calculation every workweek, not monthly, because the FLSA operates on a workweek basis.
Reconcile thresholds explicitly before signing. The federal overtime threshold is 40 hours per workweek. The FLSA salary basis threshold for many exemptions is USD 684 per week, though litigation and rulemaking have shifted this figure, so verify the current standard with a qualified professional rather than relying on an older number. Quota thresholds are contractual, not legal, and vary by employer.
Limits of what commission data can tell you
Commission plans are contractual and jurisdiction-specific. Federal law sets overtime and minimum-wage floors, but state wage statutes govern when commission is earned, how plans can be modified, and what happens at termination. A plan that is lawful in one state may be unenforceable in another.
Published averages for commission rates obscure the denominator and the trigger. Two jobs advertising "10% commission" can differ by 60% or more in expected annual pay once quota thresholds, tier structures, and clawback terms are applied. Any comparison that ignores those variables is not a comparison of pay.
