CommissionlyReal Estate Commission Calculator with Broker Split
This real estate commission calculator with broker split shows a percentage split, a cap, or a flat desk fee, and how much of this deal hits the cap.
How to calculate a real estate commission with a broker split
The side commission is still price times your rate. On the prefilled $450,000 listing at 3%, that is $13,500. A referral comes off first. What remains is the amount the split, the cap, or the flat fee is applied to. An agent commission split of 70% means the broker's share is 30% until a cap says otherwise.
A percentage split is the simple case. Thirty percent of $13,500 is $4,050 to the broker and $9,450 to you, before franchise and transaction fees. A $295 transaction fee then leaves $9,155. Use this model when the agreement is a plain split with no cap.
A cap changes only the broker's share. You still compute the 30%, but the broker collects it only until your year-to-date payments reach the cap. The prefilled cap is $20,000 with $18,000 already paid, so $2,000 of room is left. This deal would owe $4,050, but only $2,000 is collected. That $2,000 is what counts toward the cap, and the cap is then full.
A flat fee ignores the percent. The broker takes the dollar amount you enter, but not more than the commission left after referral. Franchise and the transaction fee still come off your remainder. Caps and flat fees are contract terms. This broker split calculator does not know your company's anniversary year or which fees count toward the cap.
Worked example
Percentage model: $13,500 listing side, no referral, 70% to you. Broker fee $4,050. Agent share $9,450. Transaction fee $295. Agent net $9,155 before taxes. Seller net in the same file, with both sides paid by the seller and 2% other costs, is $414,000.
Cap model with the prefilled $20,000 cap and $18,000 already paid: room is $2,000, so the broker fee on this deal is $2,000, not $4,050. You keep $11,500 before the $295 fee, which is $11,205. The line under the result states that $2,000 of this deal counts toward the cap.
How broker splits are usually written
Brokerage agreements use a few repeating shapes. One is a fixed percent on every deal. Another is a percent until a dollar cap, then 100% to the agent for the rest of the cap period, sometimes still minus a transaction fee. A third is a monthly desk fee or a flat amount per closing instead of a percent. Some add a franchise percent on the agent's share.
The cap input is the amount you pay the broker, not your production total, unless your agreement defines the cap that way. If your cap counts something else, do not force this page to match it. Type the remaining room as if it were the whole cap and set year-to-date to zero. The real estate commission calculator is the same engine without the cap fields.
| Model | Broker receives on this deal | You keep before franchise and the $295 fee |
|---|---|---|
| 70% to you, no cap | $4,050 | $9,450 |
| 70% with $2,000 cap room | $2,000 | $11,500 |
| $500 flat fee | $500 | $13,000 |
FAQ
What is an agent commission split?
It is the percent of your side, after any referral, that you keep. A 70/30 agent commission split means you keep 70% and the broker keeps 30%. On $13,500 with no referral, that is $9,450 and $4,050. The split applies to the commission, not to the sale price. A 70% split is not 70% of $450,000.
How does a broker split calculator handle a cap?
It computes the broker's percent, then limits that fee to the cap room you have left. If the room is $2,000 and the percent would be $4,050, the broker fee is $2,000 and the rest stays with you. The amount that counts toward the cap is the fee actually paid, $2,000. After that, the room on this deal is zero.
What happens after I reach the cap?
On this page, a full cap means the broker's percentage fee on the next deal is zero. You still subtract a referral, a franchise percent, and a flat transaction fee if those boxes are filled in. Some agreements reset the cap on a calendar year or an anniversary. Enter the year-to-date number that matches the contract.
How is a flat per-deal fee different from a split?
A flat fee is a dollar amount, not a percent of the commission. A $500 desk fee on a $13,500 side leaves $13,000 before other deductions. If the fee is larger than the commission left after referral, the page will not take more than that remainder. It does not decide whether your company also charges a monthly fee.
Does the cap include my franchise fee and transaction fee?
Not in this calculator. The cap limits the broker's percentage share only. Franchise and the transaction fee are subtracted after that, from your side. If your agreement rolls those into the cap, the result will not match the company statement. Use the year-to-date box for payments that actually count, and read the agreement.
Can I use this for a buyer-side deal?
Yes. Choose buyer agent as your side and enter that side's rate. The split, cap, and flat fee run on the buyer-side gross after referral. Seller net still depends on who pays the buyer agent. A buyer-paid fee is not removed from the seller's sale price in the seller-net line.
