About the Commission Calculator
Commission pay is simple in concept — a percentage of what you sold — but it stops feeling simple the moment you're trying to project a full paycheck that blends a base salary with variable commission, or comparing an offer that's commission-only against one with a safety-net base underneath it.
This calculator does that blend directly: commission earned on a given sale amount, added to whatever base salary applies for the period, so the total pay figure is the one that actually matters for budgeting.
It's aimed at sales roles sizing up a paycheck or comparing job offers with different base/commission splits, where the headline commission rate alone doesn't tell the whole story.
Your sale figures and pay structure stay in your browser and aren't sent anywhere.
Frequently asked questions
How is commission usually calculated?
Most straightforwardly as a flat percentage of the sale amount, which is what this calculator models. Many real commission plans are more complex — tiered rates that increase past certain thresholds, or commission only on profit margin rather than sale price — so treat a flat-rate estimate as a starting point, not a guarantee.
Is commission taxed differently from a regular salary?
For federal withholding purposes, commission is generally treated as supplemental wages, which can be withheld at a different flat rate than regular salary — but the actual tax owed at year-end depends on your total annual income, not on how any one paycheck was withheld.
What's the difference between commission-only and base-plus-commission pay?
Commission-only pay rises and falls entirely with sales performance, with no floor in a slow period. Base-plus-commission provides a guaranteed minimum every pay period regardless of sales, with commission added on top — generally lower risk, often with a somewhat lower commission rate to offset the base.
Does this handle tiered or graduated commission rates?
No — this applies a single flat commission rate to the full sale amount. If your plan pays a higher rate above a certain sales threshold, calculate each tier's portion separately and add the results together.
How do I find the commission rate from a payout I already know?
Divide the commission earned by the sale amount and multiply by 100 — for example, $600 earned on a $10,000 sale works out to a 6% rate. Useful for checking what rate an employer or partner is actually paying you, rather than what was advertised.
