How this is calculated
Your annual GCI is the gross commission paid to your side before the brokerage takes anything. We assume your deals are of equal size (average commission = GCI ÷ deals) and run each brokerage's model deal by deal.
Split is the share the company keeps from each commission (an 80/20 split means the company keeps 20%). Cap is the most the company will take from your splits in a year — once you hit it, you keep your full commission on the rest. Royalty (used by Keller Williams) is a separate percentage with its own annual cap. A post-cap fee is a flat per-transaction charge some brokerages apply after you've capped, and a monthly fee is a fixed cost charged 12 times a year.
Every default here is an editable estimate. Splits, caps, royalties and fees vary by market, by market center, and change over time — and some, like Compass, are individually negotiated. Treat these numbers as a starting point and confirm the exact figures with each brokerage before deciding. This tool favors no brokerage and shows every assumption.
Frequently asked questions
- How is real estate commission split calculated?
- Your side of the gross commission (GCI) is split with your brokerage by a percentage — for example, an 80/20 split means you keep 80% and the company keeps 20% of each commission. Many brokerages stop taking their share once you've paid them a fixed annual amount (the cap), after which you keep closer to 100%, sometimes minus a small per-transaction fee.
- What is a brokerage cap?
- A cap is the maximum total dollars a brokerage will collect from your commission splits in a year. Once your accumulated company-side payments reach the cap, you stop paying the split and keep your full commission on remaining deals (some brokerages then charge a flat per-transaction fee instead). Caps vary by market and market center and change over time.
- eXp vs Keller Williams — which keeps more of my commission?
- It depends on your volume. With the honest defaults here, eXp uses an 80/20 split with a $16,000 cap and small post-cap fees, while Keller Williams uses a 70/30 split with a higher cap plus a capped 6% royalty. At high GCI both let you reach roughly 100% after capping; at lower volume the split percentage matters most. Enter your real numbers above to see which keeps more for you — this calculator picks no winner by default.
- Does Compass have a cap?
- Compass does not publish a single standard cap; splits and any cap are highly negotiated per agent and market. The default here models a straight 80/20 split with no cap, which is conservative — if you negotiated a cap or a higher split, edit Compass's numbers to match your actual agreement.
- What is a 100% commission brokerage?
- A 100%-commission (or 100%-cap) brokerage lets you keep all of each commission and instead charges flat fees — typically a per-transaction fee on every deal plus a monthly fee. It can be the highest take-home for high-volume agents, but the fixed fees can outweigh the benefit at low volume. The 'Custom 100%-cap' model here is fully editable so you can plug in any flat-fee brokerage you're considering.
