How This Free Commission Calculator Works

Our free commission calculator handles every common sales pay structure — flat commission, base plus commission, tiered accelerators, and quota bonus plans. Here’s how to use it:

Step 1: Choose Your Commission Structure

Select the option that matches how you’re paid: flat commission on all sales, base salary plus commission, tiered commission with accelerators for hitting higher numbers, or quota bonus where commission only kicks in after you hit a sales target.

Step 2: Enter Your Total Sales

Type in the total sales revenue you generated for the period (week, month, quarter — whatever you’re calculating for).

Step 3: Add Your Commission Details

Depending on the structure you chose, enter your base salary, commission rate, tier thresholds, or quota amount. Default values are pre-filled to give you a sample calculation.

Step 4: Set Your Estimated Tax Rate

The default of 28% is typical for mid-bracket sales reps once you account for federal income tax, state tax, and FICA. Adjust higher if you’re in a top bracket or in a high-tax state like California or New York.

Step 5: Click “Calculate Commission”

Instantly see your commission amount, total earnings, estimated take-home pay, effective commission rate, and a what-if table showing how your earnings change at different sales levels.

Frequently Asked Questions

How is sales commission calculated?

The basic formula is: Commission = Sales × Commission Rate. For example, $100,000 in sales at a 10% commission rate equals $10,000 in commission. Our free commission calculator handles this plus more advanced structures like tiered commissions (where the rate increases as you sell more) and quota bonuses (where commission only applies above a sales target).

What is a tiered commission structure?

A tiered commission plan increases your commission rate as you hit higher sales milestones. For example: 5% on the first $50,000 in sales, 8% from $50,000 to $100,000, and 12% on everything above $100,000. This rewards top performers and motivates reps to push past their quota. Tiered plans are common in SaaS, B2B, and enterprise sales.

How are commissions taxed?

Commissions are considered “supplemental wages” by the IRS. If paid separately from your regular paycheck, employers can either (1) withhold a flat 22% federal tax, or (2) combine the commission with your regular wages and use standard withholding tables. Either way, commissions are subject to all the same taxes as regular wages — federal income tax, state tax, Social Security (6.2%), and Medicare (1.45%). Our free bonus tax calculator uses similar logic.

What is a draw against commission?

A “draw” is an advance against future commissions. The employer pays the rep a guaranteed amount (often weekly or monthly), and the rep “pays it back” by earning that amount in commission. If commission earned exceeds the draw, the rep gets the difference. If commission falls short, the rep typically owes the difference (recoverable draw) or the company eats the loss (non-recoverable draw).

What’s a typical commission rate?

Commission rates vary widely by industry. SaaS sales typically pay 8%–12% of annual contract value, real estate agents earn 2.5%–3% per side of a transaction, auto sales reps earn 20%–25% of profit per vehicle, and insurance agents can earn 40%–100% of the first year’s premium on life insurance. Inside sales reps usually earn 5%–10% of revenue, with base salary making up the rest of total compensation.

Can my employer change my commission plan?

Yes — in most U.S. states, employers can change commission plans for future sales as long as they give written notice. However, commissions already earned (typically defined by when the sale closes or the customer pays) generally cannot be retroactively reduced. Some states like California have stronger protections requiring written commission agreements signed by both parties. Always read your commission plan carefully and keep a signed copy.

How do I calculate my OTE (On-Target Earnings)?

OTE = Base Salary + Expected Commission at 100% of Quota. For example, if your base is $60,000 and you’d earn $40,000 in commission by hitting your full quota, your OTE is $100,000. OTE is the standard way sales jobs are advertised. Use our free commission calculator to model what you’d earn at 80%, 100%, or 150% of quota.

Understanding Sales Commission and Compensation Plans

Sales commission is the engine that drives most sales organizations. A well-designed commission plan motivates reps to outperform, aligns their effort with company revenue goals, and rewards top producers fairly. Our free commission calculator helps you understand exactly what you’ll earn under any pay structure — but understanding the strategy behind commission plans helps you negotiate better, choose better roles, and earn more over your career.

The Four Most Common Commission Structures

Flat (Straight) Commission: The simplest structure — a fixed percentage of every sale. Common in real estate, auto sales, and independent contractor sales roles. The upside is unlimited earning potential; the downside is zero income safety net.

Base Salary + Commission: The most common structure in B2B and enterprise sales. The base typically covers living expenses (50%–70% of OTE), and the commission is the upside. This is the standard for SaaS Account Executives, inside sales, and most corporate sales jobs.

Tiered Commission (Accelerators): Commission rates increase as the rep crosses sales milestones. For example, 5% up to quota, then 10% above quota, then 15% above 150% of quota. This structure heavily rewards top performers and is widely used in tech sales.

Quota Bonus / Override: Commission only kicks in after a sales target is met. Below quota, the rep earns only base salary; above quota, every dollar of additional sales generates commission. This structure protects the company’s margins on early-stage sales but can demoralize underperformers.

How Sales Tax Works on Commission Income

The IRS treats commissions as supplemental wages, just like bonuses. When commission is paid in a separate check from regular wages, your employer can use the flat 22% federal withholding rate (37% on amounts over $1 million in a calendar year) or aggregate the commission with your regular paycheck and apply normal withholding. Either way, you owe the same total tax at year-end — withholding just changes the timing. Don’t confuse withholding rates with your actual tax liability. According to the IRS Publication 15 (Employer’s Tax Guide), all wages — including commissions — are subject to Social Security tax (6.2% up to the $168,600 wage base in 2026), Medicare tax (1.45% on all earnings, plus an additional 0.9% above $200,000), and federal/state income tax based on your bracket.

Negotiating Your Commission Plan

When you’re offered a sales role, the commission plan matters as much as the base salary. Key things to negotiate: the commission rate itself, when commission is “earned” (at signature? at customer payment? at fulfillment?), accelerators above quota, and what happens if a deal “claws back” (customer cancels). According to U.S. Bureau of Labor Statistics data, the median annual wage for wholesale and manufacturing sales reps is around $73,000, but top performers in tech sales can easily earn $200,000–$400,000+ annually through aggressive commission structures. Always get your full commission plan in writing before accepting a role.

Commission Caps: A Red Flag

Some companies cap how much commission a rep can earn in a year, claiming it prevents “outlier” payouts. This is widely considered a poor practice in modern sales — it punishes top performers, pushes them to leave once they hit the cap, and signals that the company values cost control over revenue growth. Before joining a sales org, ask explicitly: “Is there a cap on commission?” If the answer is yes, factor that into your decision.

Tracking Your Own Commission

Never trust your employer’s commission calculations blindly. Use this free commission calculator (or build your own spreadsheet) to verify every commission payment against your closed deals. Discrepancies are common — sometimes due to honest mistakes in the comp software, sometimes due to disputed deal credit. Keep records of every closed deal, customer signature date, and payment date. If you ever dispute a commission, you’ll need this documentation.
