Work out commission and total earnings
Commission-based pay ties your earnings directly to the sales you make, and knowing exactly what a given sale is worth to you is fundamental to doing the job well. This calculator computes the commission and your total earnings from a sales amount and a commission rate, and it includes any base pay, so you can see the complete picture of what a sale, or a whole period of sales, actually puts in your pocket.
Why the structure matters
Commission plans vary enormously in structure, a flat percentage of every sale, a rate paid on top of a fixed base salary, or tiers that rise as you hit higher performance, and each of these changes what a given sale genuinely earns you. Working out the commission on a specific sale, and your total including any base pay, tells you your real effective pay and helps motivate the very next sale. Seeing the numbers laid out clearly also helps you evaluate a commission offer honestly before accepting it, since a headline-grabbing high rate on low volume can easily pay you less than a modest rate on high volume.

Frequently Asked Questions
How is commission calculated?
As the commission rate applied to the sales amount, added to any base pay, giving your total earnings for that sales figure.
Why include base pay?
Because many commission plans pay a base salary plus commission, so your total combines both, which the calculator shows together.
What is it useful for?
Knowing what a sale is worth, tracking earnings, and evaluating a commission offer, since rate and volume together determine pay.
Does a higher rate always pay more?
Not necessarily. A high rate on low volume can earn less than a modest rate on high volume, which is why running the numbers matters.
