How much business is there to win?
Before you spend on a ZIP code, it helps to know the size of the prize. This tool multiplies the homes sold there in the last 12 months by the median price and by the commission rate you enter, on both the listing side and the buyer side.
Reading the table
Each sale has two sides. A 2% share of sides in a ZIP code with 300 sales is 12 closings a year. The table shows what 1%, 2%, 5% and 10% would pay, before and after your split, so you can set a goal that is ambitious and still realistic.
Why it’s an estimate
- It assumes every sale pays the rate you enter on both sides. Rates are negotiable and differ from sale to sale. Redfin put the average buyer’s agent commission at 2.42% in the third quarter of 2025, from the sales it tracks.
- Not every sale has an agent on both sides. Some buyers go without one, and some sales are private.
- We use the median price, which usually sits a little below the average, so that part pulls the figure down.
Using it
Compare the pool with what it costs to be visible there. A farm of 400 homes mailed monthly at $0.60 a piece costs about $2,900 a year. A Spotlight ad on OfferBacked starts at $10 a month per ZIP code. Neither comes with promised results. The pool tells you what a small share would be worth if the marketing works.
Questions agents ask
How much commission is paid in a ZIP code each year?
Roughly the number of homes sold × the typical price × the commission rate on each side. A ZIP code with 300 sales at $500,000 and 2.5% a side pays about $7.5 million a year.
What market share can one agent expect in a ZIP code?
It varies widely. An agent new to an area might aim for 1% to 2% of sides at first, while an agent with an established farm can hold much more.
Is the commission pool the same as sales volume?
No. Sales volume is the total price of homes sold. The commission pool is the part of that paid to brokerages, which depends on the rates negotiated on each sale.
