Quick answer
Commission = sale price × commission rate, and your share = commission × your split. A $450,000 sale at 5% yields $22,500, of which a 50% share is $11,250.
Enter the sale price, commission rate and your share. The calculator returns total commission and your take. Use this real estate commission calculator to check your own figures.

Worked examples
These examples are verified: each one is an automated test case that the live calculator must reproduce exactly.
Example 1
Inputs: Sale price = 450000; Commission rate = 5; Your share of the commission = 50.
| Result | Value |
|---|---|
| Total commission | $22,500.00 |
| Your share after split | $11,250.00 |
Example 2
Inputs: Sale price = 300000; Commission rate = 6; Your share of the commission = 70.
| Result | Value |
|---|---|
| Total commission | $18,000.00 |
| Your share after split | $12,600.00 |
The first line is the headline result (total commission). Below it the real Estate Commission Calculator lists your share after split, which describe the same case from other angles. IEEE-754 double precision; shown to the decimals indicated.
Splits
Commission is often shared between the buyer's and seller's agents and then with the brokerage. A 50% share of $22,500 is $11,250 before expenses and taxes. Splits vary by brokerage and the agent's experience.
Rates are negotiable
There is no fixed rate: it is agreed in the listing contract and changes with local rules and market practice. Enter your own rate and split. The result excludes marketing costs, fees and taxes.
How the result changes with sale price
Holding every other input at the first worked example, this table changes only sale price. It shows how sensitive the answer is to that one value; each row was produced by running this calculator.
| Sale price | Total commission | Your share after split |
|---|---|---|
| 225000 | $11,250.00 | $5,625.00 |
| 450000 | $22,500.00 | $11,250.00 |
| 900000 | $45,000.00 | $22,500.00 |
| 1800000 | $90,000.00 | $45,000.00 |
What happens with invalid input
These messages are produced by the calculator itself, so you know what to fix.
- Sale price: entering "0" shows "Sale price must be greater than 0." beside that field and no result.
- Commission rate: entering "105" shows "Commission rate must be at most 100." beside that field and no result.

Background: business metrics
Business ratios depend on exactly which costs and revenues you include, so read each page's definition. Two common checks: break-even units = fixed costs ÷ (price − variable cost per unit), so $50,000 of fixed costs with a $10 price and $5 variable cost breaks even at 10,000 units; and net profit margin = net profit ÷ revenue, so $20,000 profit on $100,000 revenue is 20%.
Return on investment ignores time: 20% over five years is far less impressive than 20% in one, so compare returns over the same period.
Assumptions and limitations
- Rates are negotiable
If a required value is empty, not a number, or outside its allowed range, the form marks that field with a message and shows no result instead of a misleading number. The automated checks deliberately try invalid entries for sale price and commission rate to confirm this.
