Big Number Calculator
Exact arithmetic on numbers of any size, using BigInt.
Commission earned, flat rate or tiered, with splits.
Commission bands
| Sales above | Rate (%) |
|---|
Each rate applies only to the sales inside its band, exactly like tax brackets. Crossing a threshold does not reprice what you already sold.

Commission earned
—
The Commission Calculator handles flat and tiered structures, applying each band only to the sales inside it the way tax brackets work, and reports the effective rate across all sales alongside the marginal rate on the next dollar.
Enter your sales figure and commission rate to get the commission earned and your total pay including base salary. Tiered structures are supported, so each band is applied to the portion of sales that falls inside it rather than the whole amount.
That detail is the one people get wrong. In a tiered plan, hitting the next band does not reprice everything you have already sold: the higher rate applies only to the sales above the threshold, exactly like income tax brackets. The calculator therefore reports the effective rate across all sales alongside the marginal rate on the next dollar. It also handles splits, which matter in real estate, where a stated commission is divided between brokerages and then again with the agent.
Crossing a threshold does not reprice earlier sales — the higher rate applies only above it, exactly like tax brackets.
Always lower than the top band, which is the figure that describes what you actually earn.
Brokerage and team splits, which in real estate reduce a headline percentage to well under half.
Total compensation rather than commission in isolation.
What the next dollar of sales actually earns you, which is what drives behaviour near a threshold.
The total value of sales in the period the commission covers.
A flat percentage, or tiered bands with a rate for each threshold.
Any base salary, and any percentage split with a brokerage or team.
Commission earned, total pay, and the effective rate across all your sales.
Each rate applies only to the sales within its band, like tax brackets. Crossing a threshold does not reprice earlier sales, so the effective rate across everything is always lower than the top band rate.
A total commission, commonly five to six percent, is usually divided between the listing and buyer brokerages, and each then splits its share with its agent. The agent typically receives well under half of the headline figure.
An advance paid before commission is earned, later deducted from it. A recoverable draw must be repaid if commissions fall short; a non-recoverable one does not, which makes it effectively a guaranteed minimum.
It is ordinary income, but employers often withhold at a flat supplemental rate, which can be higher or lower than your actual marginal rate. The difference is settled when you file, not lost.
