What Is a Sales Commission Formula?

A sales commission formula is a mathematical calculation that determines how much a salesperson earns based on their sales performance. The formula multiplies total sales by a predetermined commission rate to calculate earnings. Accounting Corner identifies several primary structures including straight commission, salary plus commission, tiered commission, and residual commission, each with distinct calculation methods.

The basic formula works like this: Commission = Sales Revenue × Commission Rate. For example, if an AE closes $50,000 in deals at a 10% commission rate, they earn $5,000.

More complex structures layer additional variables like quota attainment, product margins, or customer retention.

What Are the Different Types of Commission Structures?

Five primary commission structures dominate B2B sales in 2026:

According to business mathematics research, tiered structures are particularly common, where sales up to $100,000 earn 2% commission, the next $100,000 earns 3%, and sales above $200,000 earn 4%.

How Do You Calculate Tiered Commission Formulas?

Tiered commission formulas apply different percentage rates to different sales levels, rewarding higher performance with escalating rates. Calculate each tier separately, then add them together for total commission.

Example calculation: An SDR manager sets these tiers: 0-$50K at 5%, $50K-$100K at 7%, above $100K at 10%. If a rep closes $120,000:

• Tier 1: $50,000 × 5% = $2,500
• Tier 2: $50,000 × 7% = $3,500
• Tier 3: $20,000 × 10% = $2,000
• Total Commission: $8,000

This structure motivates reps to push past quota thresholds. Sales leaders report that tiered plans drive 25-40% more revenue from top performers compared to flat-rate structures.

What Are the Pitfalls of Tiered Commission Plans?

Three common mistakes undermine tiered commission effectiveness:

• Too many tiers: Complexity confuses reps and reduces motivation
• Unrealistic thresholds: If only 5% of reps hit top tiers, the structure fails
• Poor communication: Reps need clear visibility into current tier status and earnings

How Do Sales Leaders Calculate Residual Commissions?

Residual commission formulas pay sellers ongoing percentages based on customer retention and recurring revenue. The calculation multiplies monthly recurring revenue (MRR) by the residual commission rate for as long as the customer remains active.

Basic residual formula: Monthly Commission = Customer MRR × Residual Rate

Example: An AE closes a customer paying $5,000/month. With a 5% residual rate, the AE earns $250 every month that customer stays active. Over 24 months, that single deal generates $6,000 in total commissions.

What Makes Residual Structures Effective for SaaS Teams?

Residual commissions align seller behavior with customer success:

• Reps focus on ideal customer profile (ICP) fit, not just closing volume
• Account Executives stay engaged post-sale to prevent churn
• Long-term customer value becomes the priority over short-term wins

SaaS companies using residual structures report 30-50% lower first-year churn rates. The ongoing income stream rewards reps for quality deals and post-sale relationship building that drives revenue operations efficiency.

How Do RevOps Teams Handle Commission Compliance?

Commission compliance requires calculating regular rates correctly for overtime pay, particularly in states like California. California commission pay laws mandate that commissions be included when determining the regular rate for overtime calculations.

California overtime formula:

• Regular Rate = (Base Salary + Commissions) ÷ Total Hours Worked
• Overtime Rate = Regular Rate × 1.5 (or 2x for double-time)

Example: A rep earns $4,000 base salary plus $2,000 commission in a month with 180 hours worked. Regular rate = $6,000 ÷ 180 = $33.33/hour. If they work 10 overtime hours, overtime pay = $33.33 × 1.5 × 10 = $500 additional compensation.

What Documentation Do RevOps Leaders Need?

RevOps teams must maintain these records to ensure compliance:

How Do Sales Leaders Implement Commission Formulas?

Successful commission implementation follows these steps:

1. Define clear objectives: Align commission structure with business goals (new logo acquisition, expansion revenue, retention)
2. Set realistic quotas: Base targets on historical performance data, not aspirational goals
3. Document everything: Create written commission plans with specific calculation examples
4. Automate tracking: Use integrated platforms to eliminate manual spreadsheet errors
5. Review quarterly: Adjust rates and tiers based on market conditions and team performance
