Cost of Selling the House Calculator
Last updated July 2, 2026
Selling a home has substantial transaction costs that reduce the net proceeds well below the sale price, and many homeowners underestimate the gap between what a buyer pays and what the seller receives. The largest cost is typically the real estate agent commission: the traditional structure has been disrupted by the NAR settlement that took effect in 2024, which decoupled buyer's and seller's agent commissions, but total commission costs still typically run 4 to 6 percent of the sale price in most transactions. Closing costs — including title insurance, transfer taxes in states that charge them, attorney fees where required, and settlement agent fees — add another 1 to 2 percent. Preparation costs — repairs, painting, staging, and professional cleaning — often run $5,000 to $20,000 for a home that needs work before going to market.
Capital gains taxes add a further consideration for homes with significant appreciation. The federal exclusion of $250,000 in gains for single filers and $500,000 for married couples filing jointly covers most primary residence sales, but not all — particularly in high-appreciation markets where a home purchased years ago for $200,000 now sells for $700,000 or more. Gains above the exclusion are taxed at the applicable long-term capital gains rate — 0, 15, or 20 percent depending on income — plus any applicable state income tax and, for high earners, the 3.8 percent Net Investment Income Tax. Calculating the after-tax, after-cost proceeds from a home sale requires accounting for all of these factors, not just the listing price.
The calculation shows the net proceeds from a home sale by subtracting agent commissions (4 to 6 percent), closing costs (1 to 2 percent), preparation expenses, and any applicable capital gains taxes from the expected sale price. The resulting figure — not the listing price — is the actual capital available for reinvestment, down payment on new housing, or other uses. Knowing this number before listing is essential for accurate post-sale financial planning.
