Commission Structure

What is a Commission Structure?

A commission structure is the formula that determines how much a salesperson earns based on sales performance, typically layered on top of a base salary as a form of variable pay. Unlike a flat bonus, commission scales directly with revenue or units sold, making earnings potential largely uncapped in many plans.

What are the Most Common Types of Commission Structures?

Employers typically choose from a handful of proven formulas. Indeed outlines nine common structures, with base salary plus commission and tiered commission among the most widely used across sales organizations.

Structure	How It Works	Best Fit
Base salary + commission	Fixed base plus a percentage of sales, often a 60:40 split	Most sales roles; balances stability and incentive
Tiered commission	Commission rate increases as sales exceed set thresholds	Experienced reps, larger established teams
Draw against commission	Advance paid each period, later reconciled against earned commission	New hires ramping up, longer sales cycles
Straight commission	Earnings come entirely from commission, no base salary	Independent agents with ownership of accounts

How is Commission Typically Split With Base Salary?

The split varies significantly by role and how directly an employee influences a sale. SHRM reports that direct sales reps working new accounts average a 59/41 base-to-incentive split, the most aggressive mix among sales positions, while roles like business development and pre-sales technical support average 80/20 or higher, reflecting their more indirect connection to closed revenue.

Straight-commission plans with no base salary at all are rare outside of independent agent arrangements. SHRM's research found fewer than 2% of sales representatives in technology and life sciences companies work on pure commission, since most organizations that own their products and services need reps guaranteed enough stability to sell consistently.

What Makes a Commission Structure Effective?

A higher incentive component tends to work best for roles focused on pursuing new accounts, direct selling, or high-priced products, according to SHRM's research, while a lower incentive share fits indirect sales, team-based selling, or long sales cycles better. Forbes advises building the plan around what's realistically measurable and attainable, since a structure that looks generous on paper but is functionally impossible to hit will demotivate reps rather than drive performance.

Communicating the plan clearly matters as much as the formula itself. Pairing commission structure documentation with broader pay transparency practices helps reps understand exactly how their effort converts into earnings, rather than discovering discrepancies after a confusing paycheck.

Why Does Commission Structure Design Matter for Retention?

A poorly calibrated plan is one of the fastest ways to lose strong performers, since top sellers can typically find a better-paying commission structure elsewhere with relative ease. Reviewing plan design alongside total compensation and connecting it to advancement through a career pyramid gives reps a longer-term reason to stay beyond just this quarter's payout.

Commission changes made without clear rationale are a common driver of sales turnover, particularly when a plan shift reduces earning potential for reps already working under the old structure.

Frequently Asked Questions

Q: What is the most common commission structure?

A: Base salary plus commission is the most widely used structure across sales roles, commonly split around 60% base and 40% commission, though the exact ratio varies by role.

Q: What is a draw against commission?

A: It's an advance paid to a salesperson each period, later reconciled against the commission they actually earn. It functions similarly to a loan and is often used for new hires ramping up.

Q: Is straight commission common?

A: No. It's relatively rare outside of independent agent arrangements, since most companies need reps to have guaranteed income stability while selling company-owned products.

Q: How does a tiered commission structure work?

A: The commission rate increases as a salesperson's sales exceed set thresholds, rewarding higher performance with a higher rate rather than a flat percentage across all sales.

Q: Why do commission splits vary so much by sales role?

A: Roles with more direct influence over closing sales, like new account reps, typically carry a higher incentive share, while roles with less direct sales impact, like pre-sales support, lean more heavily on base salary.
