The Formula

Flat Rate Commission:

Commission = Sales Amount x Rate / 100

Tiered Commission:

For each tier:
  Sales in Tier = min(Remaining Sales, Tier Size)
  Tier Commission = Sales in Tier x Tier Rate / 100

Total Commission = Sum of all Tier Commissions
Effective Rate = (Total Commission / Total Sales) x 100

Flat vs. Tiered Commission — Which Is Better?

Key insight: Tiered plans are better for motivating top performers because the accelerating rate gives them a reason to push past each threshold. Flat rates are better when simplicity and predictability matter most.

Why Commission Matters for Business Success

Commission structures directly impact sales performance, team motivation, and your bottom line. Well-designed commission plans align individual success with company goals, creating a powerful feedback loop that drives revenue growth. When salespeople earn more by generating more profitable sales, everyone wins.

Effective commission structures also help with talent acquisition and retention. Top sales professionals gravitate toward companies with competitive, transparent commission plans that reward high performance. A clear commission structure signals that your business values results and provides a path for ambitious salespeople to maximize their earnings.

Most importantly, commission plans give you a variable cost structure that scales with revenue. Unlike fixed salaries, commissions only increase when sales increase, protecting your cash flow during slow periods while rewarding teams during growth phases.

Tips for Structuring Commission Plans

Common Commission Mistakes to Avoid

• Overly complex tiers — if salespeople need a spreadsheet to calculate their commission, your plan is too complicated to motivate effectively
• Thresholds set too high — if only 10% of your team hits the second tier, you’re not motivating the other 90%
• Ignoring team dynamics — individual-only commissions can create competition that hurts collaboration and customer experience
• No cap or ceiling — while rare, uncapped commissions can create situations where a single lucky deal pays someone more than their annual salary

Pro Tips for Commission Success

• Test before implementing — run commission scenarios on last year’s sales data to see how your plan would have performed
• Consider split commissions — for complex sales involving multiple team members (account exec + engineer + customer success), split commissions fairly
• Track leading indicators — commission dollars are a lagging indicator; also track calls, demos, and pipeline progression
• Communicate frequently — send monthly commission statements so salespeople always know where they stand and what they need to hit the next tier

Detailed Worked Example: Building a SaaS Commission Plan

Scenario: You’re a SaaS company with $50K average deal sizes. You want to motivate reps to close 10+ deals per quarter while maintaining healthy margins.

Step 1: Set your target commission expense at 10% of revenue.

• 10 deals × $50K = $500K quarterly revenue target
• Target commission pool: $500K × 10% = $50K per rep

Step 2: Design a tiered structure that rewards scaling:

• Tier 1: Deals 1-6 at 8% = Up to $24K commission
• Tier 2: Deals 7-10 at 12% = Up to $24K additional commission
• Tier 3: Deals 11+ at 15% = Uncapped upside

Step 3: Calculate a typical performer (8 deals):

• Tier 1: 6 deals × $50K × 8% = $24K
• Tier 2: 2 deals × $50K × 12% = $12K
• Total commission: $36K
• Effective rate: $36K ÷ $400K revenue = 9%

This structure rewards consistency (getting to 6 deals), incentivizes stretch performance (deals 7-10), and provides uncapped upside for top performers, all while keeping commission costs predictable and profitable.
