Real Estate Commission Calculator

The sticker commission on a home sale is only part of what the seller gives up. Listing and buyer-broker fees, title and escrow charges, and the mortgage, tax, insurance, and utility costs of remaining in the house until closing all reduce cash at the table. The real estate commission calculator estimates net proceeds as sale price minus percentage commission, minus additional fees, minus months on market times monthly carrying costs. On a $400,000 sale at 6% commission, $3,000 of extra fees, two months on market, and $2,000 of monthly carrying costs, net proceeds are $400,000 − $24,000 − $3,000 − $4,000 = $369,000. A $250,000 sale at 5%, $1,500 fees, three months, and $1,500 per month leaves $231,500. An $800,000 sale at 2.5% with $5,000 fees and one month of zero extra carrying cost leaves $775,000. Those examples show why a lower commission can matter less than a long listing period if the mortgage payment is large. Sellers use this estimate to compare a traditional listing, a reduced-fee brokerage, and a slightly lower offer that closes faster. Carrying costs should include the incremental amounts you would not pay after moving: principal and interest, property tax, insurance, HOA dues, utilities, and routine maintenance. Do not double-count closing costs that already sit in the additional-fees field. Commission rates are not uniform after industry practice changes, and who pays the buyer broker can be negotiated. The calculator treats the commission rate as a single percentage of sale price and does not split listing versus buyer-side shares, because that split does not change the seller’s total commission outlay. It also ignores loan payoff, capital-gains tax, and credits for repairs. Recalculate when the list price, fee quote, or expected days on market change, and confirm the net sheet with the closing attorney or escrow officer before you accept an offer.
