What is a Commission?
In sales, a commission is a form of payment that salespeople earn directly tied to the volume or value of the services or products they sell. Unlike a fixed salary, commissions serve as a powerful method to motivate sales professionals because their earning potential is directly impacted by their performance.
A commission, in its simplest form, is a straight percentage of the generated revenue. For example, a salesperson may earn a 3% commission on whatever they sell. If they close a deal for $100,000, they would earn $3,000 from that sale. While this is the most common model, businesses use various other structures depending on their goals, profit margins, and industry standards.
Different Commission Structures
There are many different types of commission structures designed to shape seller behavior. In some cases, commissions may be reduced when salespeople grant discounts, encouraging them to maintain profit margins. In others, commissions might be heavily weighted toward recurring revenue or repeat customers. The appropriate commission structure helps align a salesperson's motivations with the overall goals of the business.
1. Commission Only
In a "commission only" structure, a salesperson's compensation is based entirely on their sales. They do not receive a guaranteed base salary. For instance, a real estate agent might receive a 3% commission on the sale price of a house. If a house sells for $500,000, the agent earns:
Example: $500,000 × 3% = $15,000
This structure ensures salespeople are highly motivated, as their livelihood depends entirely on closing deals. However, it offers no financial security during slow periods.
2. Base Salary Plus Commission
In a "base plus commission" model, the salesperson earns a guaranteed base salary while also earning a commission on their sales. For example, a car salesperson may have a base salary of $1,500/month with a commission percentage of 1.5% on their total sales volume.
If they sell two cars for $25,000 each in a month, their compensation is calculated as:
Example: $1,500 + ($50,000 × 1.5%) = $2,250
This structure provides a degree of security—ensuring the salesperson can cover basic living expenses—while still maintaining a strong incentive to sell.
3. Tiered Commission Structure
In a tiered structure, the commission rate increases as the salesperson hits higher sales thresholds. This encourages top performers to continue selling even after hitting their initial quotas, rather than slowing down.
For example, a structure might dictate:
- Tier 1: 3% on sales between $0 and $20,000
- Tier 2: 5% on sales between $20,001 and $25,000
- Tier 3: 10% on sales above $25,000
Note that a salesperson who sells $27,000 worth of products does not earn 10% on the entire $27,000. They earn 3% on the first $20,000, 5% on the next $5,000, and 10% on the final $2,000.
Tier 1: ($20,000 × 3%) = $600
Tier 2: ($5,000 × 5%) = $250
Tier 3: ($2,000 × 10%) = $200
Total Commission: $1,050
How to Use This Calculator
This tool features two distinct modes to handle nearly any standard sales compensation structure:
- Simple Commission Mode: Perfect for basic percentage calculations. This mode is a "3-way" calculator—meaning if you input any two variables (e.g., Commission Amount and Sales Price), it will automatically solve for the missing third variable (Commission Rate).
- Tiered & Base Salary Mode: Designed for complex compensation plans. Enter your total sales and an optional base salary. Then, map out your tiers by defining the upper limit ("To") and the commission rate for each bracket. Leave the final tier's "To" field blank to represent an unlimited upper cap.
Frequently Asked Questions
Commission rates vary wildly by industry. For physical retail goods, rates might range from 2% to 8%. For high-margin B2B software (SaaS), standard commission rates typically fall between 10% and 15%. Real estate agents commonly split a 5% to 6% commission. A "good" rate depends entirely on the product's margin, the sales cycle length, and whether a base salary is provided.
In the United States, commissions are classified by the IRS as supplemental income. While they are taxed at the same standard income tax brackets as regular salary when you file your annual return, your employer may withhold taxes on commissions at a flat rate (typically 22%) or use an aggregate method depending on how it's paid out.
OTE stands for On-Target Earnings. It is a projected total compensation figure that assumes the salesperson hits 100% of their sales quota. It combines the guaranteed base salary plus the expected commission earned at target performance. For example, an OTE of $100,000 might consist of a $50,000 base salary and $50,000 in target commissions.
This depends on the company's "clawback" policy. Often, if a product is returned or a contract is canceled within a certain window, the company will claw back (deduct) the commission paid on that sale from the salesperson's future earnings. In a tiered system, a large refund could potentially drop a salesperson back into a lower tier for the period.
Tiered commissions combat "sandbagging"—where a salesperson hits their quota early in the month and purposefully delays closing remaining deals until the next month to ensure they hit the next quota easily. By offering accelerated rates (like 15% instead of 10%) once a quota is passed, salespeople are highly incentivized to close every possible deal within the current period.
