Calculate sales commission earnings including base salary, commission rate, and quota bonuses. See total earnings and quota achievement.
About this calculator
Sales compensation almost always mixes a fixed floor with a variable reward, and this calculator models the common structure directly: a flat Base Salary plus Commission, which is Sales Amount multiplied by Commission Rate. On top of that base commission, many plans add a Quota Bonus -- an extra bonus rate that only applies once Sales Amount reaches the Sales Quota, rewarding reps for clearing a target rather than just moving units. Total Commission combines the base commission and the quota bonus, and Total Earnings adds Base Salary on top of that, giving the full picture of what a rep actually takes home for the period.
Quota Achievement expresses Sales Amount as a percentage of Sales Quota, so a rep or manager can see at a glance how far above or below target a given period landed -- 100% means quota was hit exactly, and the calculator's Quota Met indicator flips to "Yes" the moment Sales Amount reaches Sales Quota. Because commission plans vary widely by industry and company -- some pay a single flat rate, others tier the rate at different sales levels, and some pay the bonus on every dollar sold rather than only dollars above quota -- this calculator assumes the simplest common case: one commission rate on total sales, plus one bonus rate that activates only after quota is reached. Use it to estimate take-home pay under a proposed plan, compare an offer's effective earnings against a different base/commission split, or check what a target sales number would need to be to hit a specific income goal.

Frequently Asked Questions
Does raising the Commission Rate always increase Total Commission?
Yes -- Commission is Sales Amount multiplied by Commission Rate, so for any positive Sales Amount, a higher Commission Rate produces a higher Commission dollar figure, and Total Commission (Commission plus any Quota Bonus) rises along with it. Commission Rate has no effect on whether the Quota Bonus activates, since that depends only on Sales Amount versus Sales Quota.
When does the Quota Bonus actually apply?
Quota Bonus only applies once Sales Amount is greater than or equal to Sales Quota -- fall even one dollar short and the calculator shows a $0 Quota Bonus, since this plan structure pays the bonus rate only on hitting the target, not partial credit for getting close. Once Sales Amount reaches Sales Quota, the bonus is calculated as Sales Amount multiplied by the Quota Bonus Rate, added on top of the regular Commission.
Why does Base Salary change Total Earnings but not Commission?
Base Salary is a fixed amount added after commission is calculated -- it has no role in the Commission, Quota Bonus, or Total Commission formulas, which depend only on Sales Amount, Commission Rate, Sales Quota, and Quota Bonus Rate. Total Earnings is simply Base Salary plus Total Commission, so changing Base Salary shifts Total Earnings dollar for dollar without touching any of the commission-side figures.
How is Quota Achievement different from whether the quota was met?
Quota Achievement is a continuous percentage -- Sales Amount divided by Sales Quota -- so it can read 60%, 100%, or 150% depending on how far above or below target sales landed, while Quota Met is a simple yes/no flag that only tells you whether Sales Amount reached 100% or more. Quota Achievement is more useful for tracking progress through a period, while Quota Met determines whether the bonus rate actually applies.
