Calculate sales commission earnings based on different commission structures including flat rate, tiered, and graduated commissions.
Sales commission is a form of variable compensation paid to sales representatives based on their sales performance. It serves as a powerful incentive to drive sales and align employee interests with company revenue goals. Commission can be the sole form of compensation (commission-only) or combined with a base salary to provide income stability while maintaining performance incentives.
The basic formula for flat rate commission is: Commission = Sales Amount × Commission Rate (%). For base salary plus commission: Total Earnings = Base Salary + Commission. More complex structures like tiered or graduated commissions apply different rates to different sales levels, rewarding higher performance with increased commission percentages.
| Structure Type | How It Works | Best For | Pros | Cons |
|---|---|---|---|---|
| Flat Rate | Single percentage applied to all sales regardless of volume | Simple products, consistent pricing | Easy to understand and calculate | No incentive for exceeding targets |
| Tiered | Different rates for different sales ranges, each tier calculated separately | Progressive incentives, high-volume sales | Rewards consistent performance growth | More complex to calculate |
| Graduated | Higher rate applied to all sales once threshold reached | Aggressive growth targets | Strong incentive to reach next level | Can create "cliff" effects |
| Base + Commission | Fixed salary plus commission on sales | Most sales roles, income stability needed | Provides financial security | Lower commission rates typically |
| Commission Only | 100% variable pay based on sales performance | Experienced reps, high-earning potential | Maximum earning potential | High income volatility, no safety net |
| Draw Against Commission | Advance payment repaid from future commissions | New reps, seasonal businesses | Income during ramp-up period | Creates debt if sales underperform |
Commission rates vary significantly by industry, product complexity, sales cycle length, and company size. Here are typical commission ranges across different sectors:
| Industry | Typical Rate | Structure | Notes |
|---|---|---|---|
| Real Estate | 5-6% | Split between agents | Usually 2.5-3% per agent, split with broker |
| Insurance | 5-15% | First year + renewals | Higher first year, lower renewal commissions |
| SaaS/Software | 10-20% | Base + commission | Often tiered, higher for new business |
| Retail | 1-5% | Base + commission | Lower rates due to lower margins |
| Automotive | 20-25% | Of gross profit | Based on profit, not sale price |
| Financial Services | 1-3% | Of assets managed | Recurring annual commission |
| Manufacturing | 7-15% | Base + commission | Varies by product complexity |
| Telecommunications | 5-10% | Base + commission | Often includes activation bonuses |
| Pharmaceuticals | 8-12% | Base + commission | May include territory bonuses |
| Advertising | 10-20% | Of media spend | Agency commission model |
Tiered commission structures reward higher sales volumes by applying increasing commission rates to different sales ranges. Each tier is calculated separately, and the total commission is the sum of all tiers achieved.
