What Real Estate Commission Calculator does, with a checked example
This calculator estimates what a home seller keeps after the agent commission comes out of the sale proceeds. Enter the sale price, the total commission rate, how that commission splits between the listing side and the buyer's side, and an estimated closing cost percentage, and it returns the total commission, each side's share, and the seller's net proceeds. The thing sellers most often misjudge: the commission is deducted from the sale price before anything else, so the net figure can be far smaller than the headline price suggests.
Worked example
A concrete input and expected output from the current implementation.
Input
Sale price: $400,000 | Commission rate: 6% | Split: 50/50 | Closing costs: 2% of price
->
Expected output
Total commission: $24,000, with $12,000 to the listing side and $12,000 to the buyer's side. Closing costs: $8,000. Net proceeds to seller: $368,000.
Six percent of $400,000 is $24,000, and the 50/50 split divides that total in half; the split never changes the seller's total. Deducting $24,000 in commission plus $8,000 in closing costs (2% of the price) leaves $368,000.
