Commission is the largest line item a seller pays at closing, yet it is often quoted as a single percentage without showing where the money goes. Behind that number sits a split between listing and buyer agents, a brokerage cut, possible referral fees and flat transaction fees — and only then the agent take-home that actually motivates the work.
Real Estate Commission Calculator breaks the total into every layer: listing and buyer side gross, graduated brackets for the listing, agent-versus-broker split, referral and transaction fees, and the net proceeds left to the seller. Adjust any rate and the whole breakdown updates live.
Underneath the inputs is the context that makes the figure negotiable and understandable — how splits and graduated rates work, why the brokerage cut exists, what net proceeds really mean — plus guidance for listing appointments. Everything runs in your browser; nothing is uploaded.
