Seller Cost Calculator
Selling a home costs more than most sellers expect. Between agent commissions, title and escrow fees, transfer taxes, and pre-listing repairs, total selling costs commonly run 6% to 10% of the sale price. The Seller Cost Calculator below adds it all up: enter your expected sale price, commission rate, closing costs, extra costs, and any remaining mortgage payoff to see your total cost to sell, your effective cost percentage, and the net proceeds you would walk away with. The worked example is pre-filled so you can verify every number before trusting the tool with your own.

Quick Answer
Sell for $400,000 at a 6% commission with $4,000 in seller closing costs and $1,500 in repairs and staging, and the math is: $24,000 commission plus $5,500 of other costs gives a $29,500 total cost to sell, an effective cost of 7.38%, and $370,500 in net proceeds with no mortgage left to pay. The calculator above is pre-filled with this exact sale.
Key takeaways
- Commission is the only percentage input because it is the only cost that scales with price. Everything else is a flat dollar amount you can verify on a settlement statement.
- The mortgage payoff is not a selling cost. It settles your own debt, so the calculator subtracts it only from net proceeds and keeps it out of the total cost to sell.
- The effective cost percentage is the comparison tool: it turns any commission quote or price scenario into one number you can set side by side.
- Transfer tax is the line item most sellers forget to localize. It ranges from $0 in Texas to 4% in Delaware, which is a $16,000 swing on a $400,000 sale.

How to use the seller cost calculator
Five inputs, one click. The first two are required; the last three are optional and count as zero when left blank.
- Sale price: your expected sale price. Every percentage on the page hangs off this number, so use a realistic estimate, not the aspirational list price.
- Agent commission rate: the total rate from your listing agreement. Since the 2024 NAR settlement, commissions are fully negotiable and are not set by any rule or standard, so enter the exact rate you agreed to, whether that is 6%, 5%, or a flat fee converted to a percentage.
- Seller closing costs: title search and owner’s title insurance, escrow or settlement fees, recording fees, prorated property taxes, and transfer tax. The CFPB’s rundown of closing fees lists the usual suspects and notes that which side pays them depends on the contract and state law. To see the same bucket expressed as a share of the sale price, use the closing cost percentage calculator.
- Extra costs: pre-listing repairs, staging, inspection fixes the buyer negotiates, and seller concessions. These are the costs most online estimates undercount.
- Remaining mortgage payoff: your loan balance. Watch the two outputs move independently: the payoff never changes the total cost to sell, only the net proceeds. Results stay hidden until you click Calculate.
The seller-cost formula
The math is addition and subtraction, but the structure is the point: costs stay in one bucket, your debt in another.
Total cost to sell = Commission + Closing costs + Extra costs
Effective cost to sell = Total cost to sell ÷ Sale price × 100
Net proceeds = Sale price − Total cost to sell − Mortgage payoff
Keeping the payoff out of the cost bucket is deliberate. Paying off your loan settles your own debt; it is not a transaction fee, and mixing it into the costs makes it impossible to compare two commission quotes or two price scenarios fairly. For the financing side of your next purchase, the mortgage payment calculator picks up where this one stops.
Worked example: the pre-filled $400,000 sale, plus two more runs
The pre-filled run is a $400,000 sale at 6% commission with $4,000 of closing costs, $1,500 of repairs and staging, and no remaining mortgage. The two extra runs show how the same tool reads a leaner commission and a sale with a real payoff. Every number is a verified run of the calculator above.
| Run | Total cost to sell | Effective cost | Net proceeds |
|---|---|---|---|
| Pre-filled: $400,000 at 6%, $4,000 closing, $1,500 extra, $0 payoff | $29,500.00 | 7.38% | $370,500.00 |
| $300,000 at 5.5%, $3,500 closing, $2,000 extra, $150,000 payoff | $22,000.00 | 7.33% | $128,000.00 |
| $650,000 at 4.5%, $6,000 closing, $0 extra, $280,000 payoff | $35,250.00 | 5.42% | $334,750.00 |
Where the pre-filled $400,000 goes, as shares of the sale price:
The third run is the interesting one: a lower 4.5% commission on a $650,000 sale lands at 5.42% effective cost, inside the lean band, even though the dollar commission ($29,250) is the largest of the three. Percentages let you compare across prices; dollars do not. The second run shows the payoff doing its separate job: the cost bucket is only $22,000, but net proceeds are $128,000 because $150,000 settles the loan.
Transfer tax: the line item that depends on your state
Transfer tax is the only major seller cost set by geography rather than by your contract. Some states charge nothing; Delaware charges 4%, the highest state-level rate in the country. Who customarily pays also varies: the seller pays in Florida and New York, while Pennsylvania and Delaware customarily split it 50/50.
| State | Rate | Who customarily pays | Tax on $400,000 |
|---|---|---|---|
| Florida | 0.70% doc stamps | Seller | $2,800 |
| California | 0.11% ($1.10 per $1,000) | Seller (city add-ons possible) | $440 |
| New York | 0.40% state base | Seller | $1,600 |
| Pennsylvania | 2.00% (1% state + 1% local) | Split 50/50 | $8,000 total ($4,000 seller) |
| Delaware | 4.00% | Split 50/50 | $16,000 total ($8,000 seller) |
The rates above come from state and industry sources: Florida’s documentary stamp rules, California’s $1.10-per-$1,000 documentary transfer tax, New York’s $2-per-$500 base rate, Pennsylvania’s two-layer realty transfer tax, and the Delaware Association of Realtors’ 4% figure. Local add-ons can raise the bill (Philadelphia and Pittsburgh both exceed the 2% Pennsylvania baseline), and thirteen states, including Texas, charge no statewide transfer tax at all. Whatever your number is, it belongs in the closing costs field above.
Agent commission after the 2024 NAR settlement
Since August 17, 2024, two things changed: offers of buyer-agent compensation can no longer appear on the MLS, and buyers must sign a written agreement with their agent before touring. What did not change is the negotiability: compensation was always negotiable, and every agreement must now state plainly that rates are not set by law. A 2026 industry survey put the average total commission around 5.46%, but that is an average, not a standard.
Full-service agent: pros
- Broadest buyer pool through the MLS
- Pricing, marketing, and negotiation handled for you
- Paperwork and disclosure compliance managed
Cons
- Highest cost, typically 5-6% of the price
- You pay whether or not the extra reach earns its fee
Flat-fee MLS or FSBO: pros
- Keep 2-3% more of the sale price
- Full control of showings and negotiation
Cons
- Smaller buyer pool without full MLS exposure
- Pricing mistakes and disclosure liability fall on you
- Your time becomes the marketing department
Run both scenarios through the calculator: enter 6% and then 4.5% on the same price and compare the effective cost percentages. That single comparison is worth more than any article about average commissions. From the agent’s side of the same transaction, the realtor profit calculator shows what the commission looks like after splits and expenses.
What competing calculators miss
Most tools ranking for this keyword stop at commission plus a rough closing-cost percentage, which hides the two numbers sellers actually plan around:
- Home Seller Calculator (homesellercalculator.com): the strongest competitor, with state transfer taxes and a three-way comparison of full-service vs flat-fee MLS vs FSBO. Its depth is real, but it answers with fixed scenarios rather than your exact inputs.
- Calculators.im’s home selling tool: a clean itemized breakdown with a costs-as-percentage readout, but its tips still quote 5-6% commissions as the norm with little said about post-settlement negotiation.
- Mortgage-info’s 2026 seller guide: a thorough line-by-line worksheet with a state transfer-tax table, but a static guide: no interactive tool on the page that computes your numbers.
- NetSheet.org: the authority on what belongs on a seller net sheet, and this page follows its structure, but it is a guide, not a calculator you can run twice.
- The gap this page fills: your exact commission rate instead of a scenario, the mortgage payoff kept strictly separate from selling costs, the effective cost percentage as the comparison metric, and a plain-text breakdown you can copy or share with your agent.
Frequently asked questions
The biggest cost is the agent commission, usually the largest single line item. On top of that, sellers commonly pay the owner’s title insurance policy, escrow or settlement fees, recording fees, prorated property taxes, and any applicable transfer tax. Repairs, staging, and negotiated buyer concessions add to the total.
It depends entirely on your agreements. Traditionally the total commission was split between the two sides, but since the 2024 NAR settlement, buyers may pay their own agent directly and sellers are not obligated to offer buyer’s-agent compensation. Enter whatever total rate applies to your situation.
No. It depends on the state and sometimes the county. Thirteen states, including Texas, charge no statewide transfer tax, while Delaware charges 4%. Florida sellers customarily pay 0.70%, New York sellers 0.40%, and Pennsylvania and Delaware customarily split the tax 50/50 with the buyer. Check your local rules and roll the amount into the closing costs field.
Subtract it when you want net proceeds, which is the cash you actually receive. Do not count it as a selling cost, because repaying your loan is settling your own debt rather than paying a transaction fee. The calculator above handles this distinction: the payoff reduces net proceeds but is not part of the total cost to sell.
No. Commissions go to the real estate agents. Closing costs are the administrative and government fees needed to transfer ownership, such as title insurance, escrow fees, recording fees, and transfer taxes. Many guides quote seller totals of 6% to 10% of the sale price because they combine both categories.
It is your total selling cost as a share of the sale price. A $29,500 total on a $400,000 sale is 7.38%. That single number lets you compare scenarios quickly, for example whether negotiating the commission from 6% to 5% beats accepting a lower sale price.
Close. A seller net sheet is the one-page estimate your agent or title company prepares, listing the sale price, every cost and payoff, and the net at the bottom. This calculator follows that structure and gives you a copyable plain-text breakdown, but it is an estimate for planning, not a substitute for your agent’s net sheet at closing.
Maybe, but most sellers do not. If you owned and lived in the home as your main home for at least 2 of the last 5 years, you can generally exclude up to $250,000 of gain ($500,000 for married couples filing jointly) under IRS rules. Gain above the exclusion is taxable. The calculator above does not estimate taxes; see IRS Topic 701 for the full rules.
