The Commission Formula

Commission = Total Sales × Commission Rate

Total Earnings = Base Salary + Commission

Common Commission Structures

Straight commission: Earnings are 100% commission-based, with no base salary
Base + commission: A guaranteed base salary plus commission on sales, common in many sales roles
Tiered commission: Commission rate increases at higher sales thresholds (this calculator uses a flat rate — for tiered structures, calculate each tier separately and sum them)

Why Commission Structures Vary

Companies balance the security of a base salary against the motivational power of commission-based pay differently depending on sales cycle length, deal complexity, and industry norms.

Frequently Asked Questions

Does this handle tiered commission structures?

This calculator uses a flat commission rate. For tiered structures (where the rate increases at higher sales thresholds), calculate the commission for each tier separately using the appropriate rate for each portion of sales, then sum them.

Is commission income taxed differently than regular salary?

Commission is generally taxed as ordinary income, though employers sometimes use a different withholding method (like a flat supplemental rate) for commission payments — your total tax liability at year-end is the same regardless of the withholding method used.
