Commission calculation formulas
Commission = Sales × Rate
e.g. $50,000 × 5% = $2,500
Total Comp = Base Salary + Commission
Most common for sales roles. The rate is applied to the total revenue or gross profit from the sale, depending on the employer's plan.
Commission = Units × $ Per Unit
e.g. 100 units × $25 = $2,500
Total Comp = Base Salary + Commission
Common for gig workers, delivery drivers, and roles where pay depends on completed deals or units rather than revenue value.
| Structure | Formula | Example | Best for |
|---|---|---|---|
| Commission only | Sales × Rate | $50K × 5% = $2,500 | High-performers, flexible roles |
| Base + Commission | Base + (Sales × Rate) | $4K + $2,500 = $6,500 | Most sales roles |
| Flat per unit | Units × $/Unit | 100 × $25 = $2,500 | Gig work, per-deal pay |
| Tiered commission | Varies by tier | 5% up to $25K, 8% above | Incentivizing top performance |

Commission withholding in 2026: flat rate vs aggregate method — why 22% can over- or under-withhold depending on your tax bracket
Source: IRS Publication 15, Section 7; IRS Publication 15-T (2026 withholding tables); IRC §3402(g); OBBBA P.L. 119-21 (rate extension)
The IRS classifies sales commissions as supplemental wages (same category as bonuses, overtime, and severance). Employers must use one of two federally sanctioned methods to withhold federal income tax on your commission — and the choice can significantly affect your net paycheck.
Method 1: Flat rate (22% / 37%)
- Only available when commission is paid on a separate check or clearly identified as a separate line item from regular wages on the same check.
- Rate: 22% federal on the first $1,000,000 in supplemental wages per year; 37% mandatory on any excess above $1M.
- Over-withholds for workers in the 10–12% bracket (22% > actual rate). Under-withholds for workers in the 32–37% bracket (22% < actual rate).
- Simple to administer — preferred by most payroll systems for ad-hoc commission payments.
Method 2: Aggregate method (IRS Pub 15-T)
- Commission is combined with your regular wages for the pay period, annualized, and run through the 2026 withholding tables (based on your Form W-4 and filing status).
- Result: employer withholds the difference between (combined wages withheld) and (regular wages withheld alone). Tracks your actual marginal rate more precisely.
- Required if commission is not separately identified on the paycheck — it just gets lumped into regular pay.
- Can temporarily appear very high for large one-time commissions because the annualized total pushes into higher brackets, even if your full-year income is lower.
| Tax component | Rate (2026) | Applies to | Source |
|---|---|---|---|
| Federal income tax (flat method) | 22% | First $1M supplemental wages/year | IRS Pub 15 §7 |
| Federal income tax (high earner) | 37% mandatory | Supplemental wages above $1M/year | IRC §3402(g) |
| Social Security (OASDI) | 6.2% | Up to $184,500 wage base in 2026 | SSA; IRS Pub 15 |
| Medicare (HI) | 1.45% | All wages — no cap | IRS Pub 15 |
| Additional Medicare Tax | 0.9% | >$200K single / >$250K MFJ (employer withholds at $200K) | IRC §3101(b)(2) |
| Combined federal + FICA (typical) | ~29.65% | Flat method commission for most W-2 earners | 22% + 7.65% |
Key reminder: Withholding is an estimate. Commission is ordinary income on your Form 1040, taxed at your marginal bracket rate. Over-withheld amounts are returned as a refund; under-withheld amounts are owed at filing. The TCJA brackets (10%–37%) were made permanent by OBBBA (P.L. 119-21) and apply in 2026.
Tiered commissions, draws against commission, and clawbacks: how advanced sales compensation plans work — and how to calculate them
Source: SHRM Sales Compensation Best Practices; WorldatWork Sales Compensation Survey; standard contract law on draws and clawbacks
Most sales compensation plans go beyond a flat commission rate. Understanding tiered structures, draws, and clawbacks helps you accurately forecast your earnings and avoid surprises on your paycheck.
Tiered / accelerator commission structures
A tiered structure applies different commission rates at different revenue thresholds. This rewards high performance — the more you sell, the higher your rate on additional sales. To calculate tiered commission, apply each rate only to the revenue within that tier.
Example: tiered plan
Tier 1: 5% on first $25,000 in sales → $25,000 × 5% = $1,250
Tier 2: 8% on $25,001–$75,000 → $50,000 × 8% = $4,000
Tier 3: 12% on sales above $75,000 → $25,000 × 12% = $3,000
Total on $100,000 in sales = $8,250 (effective rate: 8.25%, not the flat 12% accelerator)
Note: this is higher than a flat 5% ($5,000) — the accelerator rewards the final $25K of selling disproportionately.
Draw against commission
A draw is an advance paid before commissions are earned. There are two types:
Recoverable (clawback) draw
Must be repaid from future commissions. If you earn less than the draw, the deficit rolls forward (or is deducted from pay).
Example: drew $2,000 / earned $1,500 commission → you net $0 and owe $500 next period
Non-recoverable draw
Functions as a guaranteed minimum — if commissions fall below the draw, the employer absorbs the shortfall. You keep the draw regardless.
More expensive for employers; common in new-hire ramp periods.
Clawbacks and commission caps
Clawback provision
Employer can recoup a commission if a customer cancels, defaults, or churns within a specified window — typically 30 to 180 days post-sale. Common in SaaS, insurance, and subscription businesses. Example: sold a $50K SaaS deal at 10% = $5,000 commission. Customer cancels in month 2 under a 90-day clawback → full $5,000 is deducted from future pay.
Commission cap (ceiling)
Some plans cap total commission at a maximum per quarter or year (e.g., max $50,000/quarter). Once hit, additional sales earn no further commission — a strong incentive to review and renegotiate plan terms annually.
Quota attainment
Many plans pay reduced rates below 100% quota and accelerated rates above 100%. A rep at 80% quota might earn 70% of the stated rate; at 120% quota, they might earn 130% of the stated rate.
Real estate commission after the NAR settlement (Aug 2024): how buyer-agent fees changed, how broker splits work, and how to calculate your net commission
Source: NAR settlement agreement (March 2024, effective Aug 17, 2024); DOJ amicus brief; IRS Pub 1779 (independent contractor status)
The NAR settlement (National Association of Realtors, effective August 17, 2024) fundamentally changed how buyer's agent commissions are negotiated and advertised. Here's what changed and how it affects your commission calculation.
Before vs after NAR settlement
Before (pre-Aug 2024)
Seller offered a total commission of ~5–6% in the MLS listing, pre-split between listing agent (~2–3%) and buyer's agent (~2–3%). Buyers rarely negotiated their agent's fee directly.
After (post-Aug 2024)
Buyer's agent compensation can no longer be included in MLS listings by sellers. Buyers must have a written Buyer Representation Agreement specifying the agent's fee before touring homes. Sellers may still voluntarily offer a concession to cover buyer-agent fees — but it must be separately negotiated outside the MLS.
Calculating net commission after broker split
Most real estate agents work under a broker and split commissions with them. To find your actual take-home:
Gross commission = Sale price × Agent rate
e.g. $500,000 × 2.5% = $12,500 gross
Net commission = Gross × Agent split %
At 70% split: $12,500 × 70% = $8,750 net
At 80% split: $12,500 × 80% = $10,000 net
At 100% (fee-based broker): $12,500 − desk fee = most of $12,500
| Sale price | Agent rate | Gross commission | Net (70% split) | Net (80% split) |
|---|---|---|---|---|
| $250,000 | 2.5% | $6,250 | $4,375 | $5,000 |
| $400,000 | 2.5% | $10,000 | $7,000 | $8,000 |
| $500,000 | 2.5% | $12,500 | $8,750 | $10,000 |
| $750,000 | 2.0% | $15,000 | $10,500 | $12,000 |
| $1,000,000 | 2.0% | $20,000 | $14,000 | $16,000 |
Real estate agents: 1099 tax implications
Most real estate agents are independent contractors (1099) rather than W-2 employees. This means: (1) self-employment tax of 15.3% on net profit (both employee + employer FICA); (2) the SE tax deduction of 50% of SE tax is deductible above the line; (3) quarterly estimated payments are required once you expect to owe $1,000+; (4) business expenses (MLS fees, E&O insurance, marketing, mileage at the 2026 IRS rate) reduce taxable income. Use our 1099 Tax Calculator to estimate your full tax burden as a real estate agent.
The commission and total compensation figures above come from the sales amount, rate, units, and optional base salary you enter—not a third-party feed. We support percentage-of-sales and flat-per-unit commission in the calculator UI; our calculation engine also handles tiered rates for reference examples below. Below are the formulas, the order we follow, and worked examples you can check by hand.

Percentage of sales · Flat per unit · (Tiered rates in examples)
Percentage applies a rate to total sales revenue. Flat per unit pays a fixed dollar amount for each sale, delivery, or deal closed. Tiered plans pay higher rates as sales cross thresholds—we document the math even though the live calculator UI focuses on the first two methods.
Calculate commission earned
Sales × rate · or · Units × per-unit · or · Sum of tier bands
For percentage plans, multiply gross sales by the commission rate (5% = 0.05). For flat plans, multiply units by the per-unit payout. For tiered plans, each sales band earns its own rate on only the dollars inside that band.
Add base salary (optional)
Total compensation = base salary + commission
Many sales roles combine a guaranteed base with variable commission. When you enable base salary in the calculator, we add it to commission for total compensation and show what share of pay comes from commission.
Estimate pay by period
Divide annual commission (or total comp) by pay periods per year
The results panel shows weekly, biweekly, monthly, and quarterly estimates assuming the same commission repeats all year. This is illustrative—most commission plans vary month to month.
Worked example
$50,000 sales at 5.0%
Percentage of sales
$50,000 × 5.0% = $2,500
Flat per unit
100 units × $25 = $2,500
Base + commission
Total compensation = $50,000 base + $2,500 commission = $52,500
Tiered (reference — not in UI)
$10,000 × 5.0% = $500; $15,000 × 7.0% = $1,050; $5,000 × 10.0% = $500
Effective rate on $30,000 sales: 6.8%
| Line item | Amount |
|---|---|
| Sales amount | $50,000 |
| Commission rate | 5.0% |
| Commission earned | $2,500 |
| Effective rate | 5.0% |
| Weekly estimate | $48.08 |
| Biweekly estimate | $96.15 |
| Monthly estimate | $208.33 |
| Quarterly estimate | $625 |
What we do not model on this page
We calculate gross commission only—not federal or state income tax, FICA, self-employment tax, supplemental wage withholding methods, draws against commission, clawbacks or chargebacks, commission paid on net vs gross profit, quota accelerators beyond the tier bands you define, or employer-specific caps and floors. Tiered commission is documented in examples but not built into the calculator UI. For after-tax commission pay, use our bonus tax calculator or 1099 tax calculator.
