The number that actually matters when you sell
Every seller starts with the same exciting question — "what is my home worth?" — and a value estimate answers it in seconds. But that number is a mirage. It is what a buyer might pay, not what you keep. The figure that decides whether you can buy your next home, pay off debt, or simply move with a cushion is your net proceeds: the cash that is left after the commission, the closing costs, and your remaining mortgage are all paid off. On a typical sale that gap is enormous — selling costs alone usually swallow eight to ten percent of the price, and then your loan payoff takes its share on top. A home that "sells for 450,000" might put 175,000 in your pocket, or 195,000, or, if you bought recently with little down, almost nothing. This calculator exists to replace that guesswork with a real, itemized net sheet — the same kind a title company prepares — so you know your walk-away number before you ever sign a listing agreement.
How to use the calculator
- Enter your expected sale price. Use a realistic figure — your agent's suggested list price, a recent appraisal, or a conservative market estimate. You can re-run it at several prices to see your range.
- Set the commission. Choose a percentage (5–6% is the historic norm, split between agents) or a flat dollar amount if you have negotiated one. Selling without an agent? Set it to zero, or to just the buyer-agent rate you have agreed to pay.
- Enter your mortgage payoff. Use the principal you still owe. If you want a sharper figure, add your rate and the days until closing so the tool includes the daily interest that accrues up to the closing date.
- Add your closing costs. Use the quick percentage (about 1–2%) for early planning, or switch to Itemize to enter title and escrow, your local transfer tax rate, attorney and recording fees, and any home warranty.
- Include credits and prorations if they apply — prorated property taxes you owe and any concessions or repair credits you have agreed to give the buyer. Then read your net proceeds, the line-by-line sheet, and the verdict.
The math behind your walk-away number
The logic is simple to state and easy to get wrong if you forget a line. The calculator starts with your sale price and subtracts four buckets. First, the commission — either your percentage of the price or a flat amount. Second, your closing costs — a percentage of the price, or the sum of your itemized title, transfer tax, attorney, recording and warranty figures. Third, any credits you give the buyer, including prorated property taxes you still owe and negotiated concessions. Fourth, your mortgage payoff, optionally increased by per-diem interest: your balance multiplied by your daily rate (the annual rate divided by 365) times the days until closing. Everything except the mortgage payoff is a true cost of selling; the payoff is simply you returning money you borrowed, which is why the tool reports your "cost of sale" separately from your loan repayment. What remains after all four buckets is your net proceeds — positive means cash to you, negative means you must bring money to closing.
A worked example
Picture a 450,000 dollar sale with a 5.5% commission, a 250,000 dollar mortgage payoff, 1.5% in closing costs, and a 30-day closing at a 6.5% rate. The commission is 24,750 dollars. Closing costs are about 6,750 dollars. The payoff grows by roughly 1,335 dollars of per-diem interest to about 251,335. Your total cost of sale — commission plus closing costs — is around 31,500 dollars, or about 7% of the price. Subtract the costs and the payoff from the sale price and your net proceeds land near 167,200 dollars. That is your walk-away cash. Notice the story the numbers tell: the commission alone is the single largest selling expense, larger than every other fee combined, which is why even a half-point of negotiation is worth thousands. And your break-even price — the figure you would need just to cover the payoff and costs — sits well below your list price, meaning you have comfortable equity. A seller who bought last year with 5% down would see a very different, much tighter picture.
Why the commission is the lever that matters most
On almost every sale, the real estate commission is the biggest single line on the net sheet — typically larger than every other closing cost added together. That is precisely why it deserves the most attention. Historically commissions ran 5 to 6 percent of the sale price, split between the listing and buyer's agents. Since the 2024 industry settlement reshaped how buyer-agent compensation is advertised and negotiated, that structure is more openly flexible than it has ever been. Sellers now routinely negotiate the listing-side rate, choose flat-fee or discount brokerages, or decide separately what — if anything — they will contribute toward a buyer's agent. Each route trades money for marketing reach, negotiating muscle, and convenience, so the cheapest option is not automatically the best one. The point is not that you should always pay less; it is that you should know the dollar value of the choice. Run the calculator at 5.5% and again at 4.5% on a 450,000 dollar home and you will see roughly 4,500 dollars swing into or out of your pocket from a single percentage point. Decisions that large deserve a real number, not a shrug.
Break-even price and the underwater test
The break-even price is the quiet hero of a good net sheet. It answers a question every seller should ask before listing: what is the lowest price I can accept and still walk away owing nothing? The tool solves for it by working backwards — finding the price at which your sale exactly covers your mortgage payoff plus all the percentage-based and fixed selling costs. If that break-even figure is comfortably below what your home would realistically fetch, you have healthy equity and room to negotiate. If it is above your likely sale price, you are effectively underwater: the sale would not raise enough to clear your loan and costs, and you would have to bring cash to the closing table to make up the difference. This commonly happens when you sell soon after buying with a small down payment, before your payments and any appreciation have built equity. Knowing your break-even price early turns a nasty closing-day surprise into a planned decision — whether to wait, to rent the home out, or to budget for the shortfall.
Net proceeds are not your taxable profit
This is the single most common and most expensive misunderstanding sellers have, so it is worth stating plainly: the cash you walk away with is not the same as your taxable capital gain. Net proceeds are reduced by paying off your mortgage; capital gains are not. Your taxable gain is the sale price, minus selling costs, minus your original purchase price plus the cost of improvements — your "cost basis." A seller can pocket very little cash yet owe tax on a large gain (if they bought cheaply long ago and still carry a big loan), or walk away with a large check and owe nothing (thanks to the primary-residence exclusion). The two numbers answer different questions: net proceeds tell you how much money you will have; capital gains tell you how much, if any, you might owe the tax authorities. Use this tool for the first question, and a dedicated capital gains calculator for the second — they are complementary, not interchangeable.
Common mistakes this prevents
Pro tips for a bigger walk-away number
- Negotiate the commission with the dollar figure in hand. Knowing a single point is worth thousands changes the conversation. Ask, compare flat-fee options, and decide deliberately.
- Get an official payoff statement. Your lender's payoff quote is exact and dated; use it instead of your last statement balance, since interest keeps accruing daily until closing.
- Shop title and escrow where allowed. In many states these fees are not fixed, and choosing your own provider can trim hundreds without affecting the sale.
- Confirm your local transfer tax. Rates range from zero to well over one percent depending on the state, county and even city — verify yours rather than guessing, because on a large sale it is real money.
- Run multiple price scenarios. Model a likely, a low, and a high sale price so you know your proceeds at each, and you negotiate from information instead of hope.
Where this fits in your moving math
Your net proceeds are the hinge of an entire move. They become the down payment on your next home, so pairing this tool with a mortgage payment or affordability calculator tells you what you can comfortably buy. If you are weighing whether to sell at all, comparing your equity here against the cost of staying — or against renting the property out — sharpens the decision. And before you celebrate the check, run a capital gains estimate so any tax is a planned line item, not a spring surprise. Selling a home is one of the largest financial transactions most people ever make; going into it with a precise, itemized net sheet rather than a rough guess is the difference between a confident move and an anxious one.
Frequently asked questions
Is this calculator free?
Yes — completely free, no sign-up and no lead form. Everything runs in your browser.
Does my data get saved or sent to an agent?
No. Unlike many seller net sheets, there is no email capture and no server. Your numbers never leave your device.
What commission rate should I use?
5–6% total is the historic norm, but commissions are negotiable. Use your actual agreed rate, a flat amount, or zero for a for-sale-by-owner sale.
Why is my payoff higher than my balance?
Because mortgage interest accrues daily up to closing. The tool adds that per-diem interest when you enter your rate and days to closing.
What if I owe more than the home sells for?
Your net proceeds show as negative, meaning you would bring cash to closing. The break-even price tells you the price needed to avoid that.
Are net proceeds the same as my taxable gain?
No. Net proceeds are your cash; taxable gain ignores the mortgage payoff and uses your purchase price and improvements. Check capital gains separately.
Should I use the percentage or itemized closing costs?
Use the quick percentage (1–2%) for early planning, then itemize once you have real title, escrow and transfer-tax quotes.
Does it work for a paid-off home?
Yes — set the mortgage payoff to zero and your net is simply the sale price minus selling costs.
What about the buyer's closing costs?
Those are normally the buyer's responsibility and are not deducted from your proceeds, unless you agree to a seller concession, which you can enter.
How accurate is this estimate?
It is a careful estimate based on the figures you enter. Your title or escrow company's official settlement statement is the final, binding number.
