Before building Commission Calculator, we checked a widely used online tiered commission calculator directly.
Progressive commission rate calculator, correctly tiered
It handles the core math right: commission changes based on total sales, with rates applying progressively across ranges — similar to how income tax brackets work. Sales price, base commission, variable commission, and tier ranges are all configurable.
Agent broker commission split calculator: a gap in the output
What it doesn't do: split the resulting commission between multiple parties. Real-world commission is often shared — an agent keeping 70% with the rest going to a broker or house — and there's no field for that anywhere in the tool.
Sales commission calculator breakdown, tier by tier
This tool adds both pieces: a split percentage so you see your actual share, not just the raw total, and a breakdown table showing exactly how much sales fell into each tier and what that tier contributed to the total commission — $60,000 in sales across three tiers works out to $3,000 total, and the table shows precisely how that number was built.
