Understanding Sales Commission Structures
Sales commission is the variable component of a salesperson's compensation tied directly to revenue generated. According to the Sales Management Association, companies spend between 5% and 20% of revenue on sales compensation, making commission structure design one of the most impactful decisions a sales organization makes. The right plan motivates top performers, aligns rep behavior with company goals, and drives predictable revenue growth.
A flat rate structure is the simplest: every dollar of revenue earns the same commission percentage. It works well for transactional sales with consistent deal sizes. A tiered structure pays increasing rates as a rep hits higher revenue brackets, rewarding sustained performance. Accelerators add a multiplier above quota, creating exponential upside for top performers. And draw against commission provides a guaranteed minimum income while a rep ramps up, with the draw deducted from future earnings.
Our calculator lets you model all of these structures, compare them side by side, and project your total on-target earnings (OTE) across best, target, and worst case scenarios. Whether you're a sales rep evaluating a job offer or a manager designing compensation plans, this tool shows exactly how different structures impact take-home pay at every revenue level.

Frequently Asked Questions
What commission structures does this calculator support?
Five types: Flat Rate (fixed percentage on all sales), Tiered (different rates at different revenue brackets), Accelerator (base rate with a bonus multiplier above quota), Draw Against Commission (guaranteed draw deducted from earned commission), and Custom Formula (user-defined brackets and rates). You can save multiple structures and switch between them instantly.
How does the OTE (On-Target Earnings) projector work?
Enter your base salary and projected revenue for target, best case, and worst case scenarios. The projector calculates your total compensation (base + commission) for each scenario, shows monthly breakdowns, and visualizes the split between salary and variable pay. This helps you understand realistic earnings ranges before accepting a comp plan.
Can I compare two commission plans side by side?
Yes. The Compare Plans tab lets you select any two saved commission structures and see a line chart showing earnings at every revenue level from $0 to $500K. It automatically finds the crossover point where one plan becomes more lucrative than the other, plus a comparison table at key revenue milestones.
