Know what this estimate is based on
- Jurisdiction
- United States — state and local practice
- Scope and limitations
- Educational estimate only. U.S. real estate costs are local: property tax rates, transfer and recording taxes, title practice, who customarily pays which closing cost, and landlord-tenant rules all change by state and often by county or city. Agent commission is negotiable and, since the 2024 NAR settlement, buyer-agent compensation is negotiated separately rather than assumed. Only a lender's Loan Estimate, a title company's fee sheet or a signed contract binds a number.

How to use
- 01
Enter your mortgage payoff — the figure from the lender, not the balance on last month's statement.
- 02
Enter fixed selling costs: attorney, title, inspection credits, anything that does not scale with price.
- 03
Enter the commission and transfer tax as percentages, because those do scale.
- 04
Read the break-even price, then the cushion against what you think the home is worth.
- 05
Use the target table to find the price you would need to walk away with a specific amount.
Formula
The percentage costs total commission plus transfer tax plus any other percentage charges. The break-even price is the mortgage payoff plus the fixed selling costs, divided by one minus that percentage total — not added to it, because commission is charged on the price rather than on the payoff. The price needed for a target walk-away amount adds the target to the numerator. Costs at the break-even price are that price times the percentage total, plus the fixed costs. The naive answer — payoff plus fixed costs plus the percentage applied to the payoff — is computed too, and the gap between it and the correct figure is reported, because that gap is the mistake this page exists to prevent. A guard covers the impossible case: if the percentage costs reach one hundred percent no price breaks even, and the page states exactly that rather than printing a number.
Example
A $385,000 payoff, $4,500 of fixed selling costs, 5% commission and 0.5% transfer tax, against an estimated value of $420,000. Step 1 — Percentage costs total 5.5%, so 94.5% of the price survives them. Step 2 — Break-even: ($385,000 + $4,500) / 0.945 = $412,169. Step 3 — Costs at that price: $412,169 x 5.5% + $4,500 = $27,169. Step 4 — Cushion: $420,000 − $412,169 = $7,831 of room. Now the mistake. The intuitive answer is $385,000 + $4,500 + 5.5% of $385,000 = $410,675. That is $1,494 too low, and a seller who priced to it and accepted an offer at it would arrive at closing $1,494 short. The cushion figure is the one to act on. Under $8,000 of room on a $420,000 home is thin — one inspection credit or a below-contract appraisal erases it. It says price with care, keep the commission conversation open, and do not treat any offer above $412,169 as automatically good news.
Definitions
- Break-even price
- The sale price that clears the mortgage and all selling costs with nothing left over.
- Payoff quote
- The lender's statement of the exact amount to clear the loan on a given date. Higher than the statement balance.
- Fixed selling costs
- Costs that do not scale with price: attorney, title, warranty, inspection credits.
- Percentage costs
- Costs charged on the sale price: commission, transfer tax, excise tax.
- Cushion
- The gap between the break-even price and what you believe the home is worth.
- Underwater
- Owing more than the home can sell for after costs. Shows here as a negative cushion.
- Short sale
- Selling for less than the payoff with lender consent. Slow, credit-damaging, and sometimes the only option.
- Seller concession
- A credit to the buyer at closing. A fixed one is a fixed cost; a percentage one is a percentage cost.
- Net proceeds
- What is left from a given price. The inverse of this calculation.
- Gross-up
- Dividing by one minus the percentage costs, rather than adding them. The correct arithmetic here.
- Appraisal shortfall
- A lender valuing the home below the contract price, which is why a break-even listing price is risky.
- Walk-away amount
- Cash you want in hand after closing. The target this page can solve for.
Good to know
Divide, do not add
The most common error in estimating a break-even sale price is adding the costs to the payoff. Commission and transfer tax are percentages of the sale price, so raising the price to cover them raises them too — the arithmetic is circular and it has to be solved rather than accumulated. Dividing the fixed obligations by one minus the percentage costs gives $412,169. Adding the percentages to the payoff instead gives about $410,675, understating the requirement by $1,494. That gap is small enough to be invisible in a mental estimate and large enough to matter at a closing table where the seller expected to walk away clean. The higher the percentage costs, the wider the error grows: at 10% of total percentage costs it more than doubles.
Everything the payoff figure has to include
The mortgage balance on your statement is not the payoff. The payoff adds per-diem interest from the last payment through the closing date, and it may add a prepayment penalty, a recording or reconveyance fee, and a wire fee. It also has to include anything else secured against the property: a home equity line even if the balance is zero, since it must be closed and released; a second mortgage; a solar lease or PACE assessment, which in some states must be paid off at sale; a contractor's or tax lien; and unpaid HOA dues, which most associations can lien. Any one of these discovered during escrow raises the number you need and does so at the worst possible moment. Order an actual payoff statement from the servicer and an HOA estoppel letter early, rather than working from the last statement.
The half-point figure is your negotiating range
Half a percentage point of commission moves the break-even price by $2,181 here. That is the single most useful number on the page for a seller who is tight against their payoff, because it converts a commission negotiation into the price relief it actually buys. It works in both directions: it says what a discount broker is worth to you in price terms, and it says how much room you have to accept a lower offer if you can negotiate the commission down. The same logic applies to the transfer tax where local custom makes it negotiable, and to a repair credit, which is functionally a price reduction. When the required price is uncomfortably close to what the market will bear, the cost side is usually more negotiable than the price side.
When the cushion is thin, and when it is negative
A $7,831 cushion against a $420,000 estimate is under 2% of value — inside the margin of error of any valuation, and well inside the range a single inspection can consume. A cushion that thin means the sale depends on the market delivering close to the estimate and on nothing being found. Where the cushion goes negative, the sale is underwater and there are three paths: bring cash to closing, which is the cleanest and the least popular; negotiate a short sale, which requires lender approval, takes months, and leaves a credit mark; or do not sell. Keeping and renting is the fourth, and the Rent vs Sell Calculator prices it. The one approach that fails is listing anyway and discovering the shortfall at the closing table, because by then a buyer has expectations and a move is scheduled.
Break-even is not the same as your target
This page defaults to zero cash out, which answers whether a sale is possible. It rarely answers whether a sale is sensible. Set the target cash to what you actually need — the down payment on the next home, moving costs, a deposit on a rental, a debt to clear — and the required price rises accordingly, at a rate of about $1.06 of price for every dollar of target once the percentage costs are grossed up. That is the number to compare against the market. It also frames time properly: if the required price is above what comparable sales support today, waiting is a strategy with a cost, and the cost is the carrying cost of the months you wait plus the risk that the market moves the other way.
Frequently asked questions
Why can I not just add the costs to what I owe?
Because commission is charged on the sale price, not on the payoff. Adding 5% of the payoff undercounts, since the commission on the higher final price is larger. The payoff has to be divided by what is left after the percentages, and on these figures that difference is $1,494.
What is a payoff quote?
A statement from your lender of the exact amount to clear the loan on a given date, including interest to that date and any recording or wire fees. It is usually a few hundred dollars more than your statement balance, and it expires — request one close to closing.
What are fixed versus percentage costs?
Fixed costs do not change with the sale price: attorney fees, title work, a home warranty for the buyer, an inspection credit. Percentage costs scale: commission, transfer tax, sometimes an excise tax. The distinction is what makes this a division rather than an addition.
What if I am underwater?
The page shows it as a negative cushion — the amount you would have to bring to closing. Options at that point are waiting for appreciation, paying down the balance, renting the property instead, or asking your lender about a short sale. None is quick, which is why finding out early matters.
Does the down payment I made affect this?
Not directly. What matters is the payoff today, not what you originally put in. A large down payment shows up as a smaller payoff, which is where its effect appears.
Should I include the tax on the gain?
Not here — this is a cash calculation, and most home sales owe no tax thanks to the section 121 exclusion. If your gain exceeds it, run the Home Sale Capital Gains Calculator and treat that tax as a separate reserve rather than as a selling cost.
What if I want to walk away with a specific amount?
Enter it as the target and the page solves for the price. The table also shows the price for walking away with $10,000, $25,000, $50,000 and $100,000, which is useful when the target is a down payment on the next place.
How much does cutting the commission help?
More than most sellers expect, because it works twice: it lowers the costs and lowers the price you need. Half a point off commission takes roughly $2,170 off the break-even price on these figures.
What about buyer concessions?
Treat a fixed credit as a fixed selling cost and a percentage concession as a percentage cost. Either way it raises the break-even price, which is exactly the point of pricing it before agreeing to it.
Is this the same as my net proceeds?
It is the inverse. Net proceeds start from a price and tell you what is left; this starts from what must be left and tells you the price. Use the Home Sale Proceeds Calculator once you have an actual offer.
Why does the page sometimes refuse to give a price?
If the percentage costs total 100% or more, no sale price breaks even — every extra dollar of price is entirely consumed by costs. That is arithmetically impossible in practice, and it means a percentage was entered wrongly.
Should I list at the break-even price?
No. It is a floor, not a strategy. Listing at your break-even leaves no room to negotiate, no cushion for an appraisal shortfall, and nothing for the repairs a buyer will ask for. Know the number, then price above it.
