How real estate commission is worked out
The total commission is the sale price times the rate. The total is split between the listing side and the buyer side by the listing share, and the listing broker takes a cut of the listing side before the listing agent is paid. The seller keeps the price minus the total commission. Every dollar in the chain is a percentage of a percentage, so the order matters: the broker cut is a cut of the listing side, not of the whole sale.
At the defaults — sale price $500,000, rate 5.5%, listing share 50%, broker cut 30% — the total commission is $500,000 × 5.5% = $27,500.00. The listing side gets 50% of it, $13,750.00, and the buyer side gets the other $13,750.00. The broker takes 30% of the listing side, $4,125.00, so the listing agent keeps $9,625.00. The seller nets $500,000 − $27,500.00 = $472,500.00, which is 94.50% of the price, or $55.00 of commission per $1,000 of price.
| Case | Total commission | Net to seller | Listing / buyer side |
|---|
| Default ($500,000 at 5.5%, 50/50, 30% broker) | $27,500.00 | $472,500.00 | $13,750.00 / $13,750.00 |
| Sale price $300,000 | $16,500.00 | $283,500.00 | $8,250.00 / $8,250.00 |
| Sale price $750,000 | $41,250.00 | $708,750.00 | $20,625.00 / $20,625.00 |
| Sale price $1,000,000 | $55,000.00 | $945,000.00 | $27,500.00 / $27,500.00 |
| Rate 4% | $20,000.00 | $480,000.00 | $10,000.00 / $10,000.00 |
| Rate 6% | $30,000.00 | $470,000.00 | $15,000.00 / $15,000.00 |
| Rate 3% | $15,000.00 | $485,000.00 | $7,500.00 / $7,500.00 |
| Split 60/40 | $27,500.00 | $472,500.00 | $16,500.00 / $11,000.00 |
| Split 70/30 | $27,500.00 | $472,500.00 | $19,250.00 / $8,250.00 |

The worked example, line by line
Setup: sale price $500,000, rate 5.5%, listing share 50%, broker cut 30%.
Line 1 — the total commission. $500,000 × 5.5% = $27,500.00.
Line 2 — the listing side. $27,500.00 × 50% = $13,750.00.
Line 3 — the buyer side. $27,500.00 × 50% = $13,750.00.
Line 4 — the broker cut. $13,750.00 × 30% = $4,125.00.
Line 5 — the listing agent keeps. $13,750.00 − $4,125.00 = $9,625.00.
Line 6 — the net to seller. $500,000 − $27,500.00 = $472,500.00, which is 94.50% of the price.
Reverse: a $20,000.00 commission at 5.5% needs a $363,636.36 sale; a $25,000.00 commission needs a $454,545.45 sale; $15,000.00 on $500,000 is a 3.00% rate; netting $450,000.00 at 5.5% needs a $476,190.48 sale; the most the rate can be while the total stays at or under $22,000.00 on $500,000 is 4.40%.
Every branch, checked
Sale price $300,000: the total is $300,000 × 5.5% = $16,500.00, so the seller nets $283,500.00 and each side gets $8,250.00. The broker takes $2,475.00 and the agent keeps $5,775.00.
Sale price $750,000: the total is $41,250.00, so the seller nets $708,750.00 and each side gets $20,625.00. The broker takes $6,187.50 and the agent keeps $14,437.50.
Sale price $1,000,000: the total is $55,000.00, so the seller nets $945,000.00 and each side gets $27,500.00. The broker takes $8,250.00 and the agent keeps $19,250.00.
Rate 4%: the total is $20,000.00 and the seller nets $480,000.00. A point and a half off the rate is worth $7,500.00 to the seller.
Rate 6%: the total is $30,000.00 and the seller nets $470,000.00. A half-point above the default costs the seller $2,500.00.
Rate 3%: the total is $15,000.00 and the seller nets $485,000.00. Two and a half points under the default is worth $12,500.00.
Split 60/40: the listing side gets $16,500.00 and the buyer side gets $11,000.00. The total and the net do not change — the split only moves money between the two sides.
Split 70/30: the listing side gets $19,250.00 and the buyer side gets $8,250.00. The broker takes $5,775.00 of the bigger listing side and the agent keeps $13,475.00.
Broker cut 20%: the broker takes $2,750.00 and the listing agent keeps $11,000.00. Ten points off the broker cut is worth $1,375.00 to the listing agent on this sale.
Reverse — the other way round: a $20,000.00 commission at 5.5% needs a $363,636.36 sale; a $25,000.00 commission needs a $454,545.45 sale; $15,000.00 on $500,000 is a 3.00% rate; netting $450,000.00 at 5.5% needs a $476,190.48 sale; keeping the total at or under $22,000.00 on $500,000 caps the rate at 4.40%.
What the defaults assume
The model assumes the sale price, the total rate, the listing share and the broker cut you enter, and it splits the total exactly as entered. It assumes the broker cut is a cut of the listing side only, and it leaves out closing costs, transfer taxes, mortgage payoff, repairs and any buyer concessions — the net to seller here is the price minus the commission, not the cash at closing. Rounding convention: money is rounded to cents, percentages are shown to two decimals, and all figures are computed from unrounded values, rounded only for display.

Who uses this
- The seller pricing a home: they learn a $500,000 sale at 5.5% costs $27,500.00 and nets $472,500.00 — so they know what the sale is really worth, and they check the 3% case at $485,000.00 before negotiating the rate.
- The listing agent checking a split: they learn a 50/50 split leaves the listing side $13,750.00 and a 70/30 split leaves it $19,250.00 — so they know the split is the lever, and they check the 20% broker case at $11,000.00 kept before signing the listing.
- The buyer agent estimating a payday: they learn the buyer side is $13,750.00 at 50/50 and $11,000.00 at 60/40 — so they know what the listing agreement is worth to them, and they check the $750,000 case at $20,625.00 before showing the house.
- The seller working backwards from a target: they learn netting $450,000.00 at 5.5% needs a $476,190.48 sale — so they know the asking price that clears their number, and they check the $363,636.36 case before setting the price.
Accuracy & limitations
The math is exact for the numbers you enter: the total is the price times the rate, the sides split the total by the listing share, the broker cut is a cut of the listing side, and the net is the price minus the total. What the model cannot do is read your listing agreement for you: check the rate and the split, because a 3% rate and a 6% rate give totals $15,000.00 apart. It leaves out closing costs, transfer taxes, mortgage payoff, repairs and buyer concessions — the net here is price minus commission only.
