Naperville Net Proceeds Calculator
What will you actually net when you sell a Naperville home?
Your net proceeds are the sale price minus everything that leaves the closing table before you do: your mortgage payoff, the commission you negotiate, the Illinois state and county transfer stamps, the property tax credit you give the buyer, your attorney fee, title and settlement charges, and anything you spend on prep or credit back in repairs. In Naperville, two of those lines are fixed by published rate, so a price is all you need to compute them exactly. A third, the property tax credit, is exact arithmetic once you know your closing date and what your contract says about proration, which is why this page shows the formula rather than a number. A fourth, your attorney fee, is a flat quote you can ask for today. The rest are yours to fill in, and no honest page can fill them in for you.
That is the difference between this page and a national calculator. A national tool applies a percentage to your price and hands you a number. It does not know that the City of Naperville transfer stamp is buyer-paid by city ordinance, so it deducts a stamp you never buy. It does not know that Illinois bills property taxes a year behind, so it usually leaves out what is often the single largest knowable line on a Naperville seller's sheet. Both errors point the same direction: they make the arithmetic look tidier than it is.
Here is the honest split. On the two worked examples below, the costs that can be calculated in advance came to about 1.8 percent and 1.9 percent of the sale price. Everything bigger than that is either a rate you negotiate or a quote you request. For the full catalogue of selling costs and how each one behaves, read what it costs to sell a home in Naperville. If you do not yet have a realistic price to start from, begin with how a home valuation works in Naperville, because a net sheet built on a guess is a guess.
The Naperville seller net sheet, line by line
A net sheet is a subtraction, taken in closing order. Here is every line, who customarily pays it, and how it is figured. Custom is not law. Several of these lines, including the state and county transfer stamps and the property tax credit, are set by custom rather than by statute and are commonly reallocated by negotiation in your purchase contract. Others are not: your mortgage payoff is owed to your lender and your own attorney fee is owed to your attorney, whatever the purchase contract says, your commission is set in your listing agreement rather than in the purchase contract, and the City of Naperville stamp is assigned to the buyer by city ordinance. Read what you sign.
| Line | Who customarily pays | How it is figured |
|---|---|---|
| Sale price | — | The contract price. Not your list price, and not an online estimate. |
| Mortgage payoff | Seller | Your lender issues a payoff figure good through a specific date. It includes interest to that date, so it is usually a little higher than the balance on your last statement. |
| Illinois state transfer stamp | Seller, by custom | $0.50 per $500 of price, counted per $500 or fraction of $500 (35 ILCS 200/31-10). |
| County transfer stamp, DuPage or Will | Seller, by custom | $0.25 per $500 of price, on the same rounding. The rate is the same in both counties. |
| City of Naperville transfer stamp | Buyer, by city ordinance | $1.50 per $500, rounded up to the next $500. It appears on the closing statement, but not on your side of it. |
| Property tax credit to the buyer | Seller | Illinois bills property taxes a year behind, so at closing you credit the buyer for the days you owned the home this year. Figured from a tax bill and your closing date; which bill, and any adjustment, is set by your contract. The Naperville property tax calculator estimates the annual bill this credit comes from. |
| Real estate attorney | Each side pays its own | A flat fee. Attorneys in the area commonly quote in the $500 to $1,500 range for a standard residential closing, with about $650 the figure cited most often. |
| Title, settlement, and recording | Allocated by contract | Quoted by the closing agent for your price and your file. There is no published Naperville figure for this, so this page does not invent one. Ask for the quote in writing. |
| Prep, repairs, and concessions | Seller | Your own choices before listing, plus anything you agree to credit after an inspection. |
| Commission you negotiate | Seller, per the listing agreement | A percentage of the sale price that you and your agent agree on. It is not set by law and is fully negotiable. Any contribution you make toward buyer-agent compensation is a separate, negotiable decision, not an assumed part of your listing-side rate. |
| Your net proceeds | — | The sale price minus every line above it. |
Worked example: a Naperville sale at the citywide median
At $594,644, the seller costs that can be calculated in advance come to $10,660.10, about 1.79 percent of the sale price. The largest of them is not a tax on the sale at all. It is the property tax credit you hand the buyer, and it moves with your closing date rather than with anything about the house.
Assumptions used, and where each one comes from.
- Sale price $594,644. This is the median sale price Redfin reported for Naperville, all home types, for the three months ending May 2026. Sources disagree by design, not by error: Redfin reported $619,663 for the April to June 2026 window, and Zillow put its typical home value for Naperville at $636,281 as of June 30, 2026. Treat the low $600,000s as the current band rather than one exact figure, and see the Naperville real estate market page for the wider picture.
- Effective property tax rate 2.05 percent. That is the median effective rate Ownwell reported for the DuPage County portion of Naperville, pulled August 3, 2026. Naperville straddles two counties and they are not the same burden: Ownwell reports 2.35 percent for the Will County portion.
- Closing on September 30, so the seller owned the home for 273 of the 365 days in the year.
- Attorney fee $650 flat, the figure most commonly cited within the $500 to $1,500 range attorneys in the area quote for a standard residential closing.
- Nothing else is assumed. Commission, title and settlement charges, prep, and the mortgage payoff are left blank on purpose. They are not knowable from public data, and inventing a number for them is the exact thing this page exists to avoid.
| Line | Amount |

| Sale price | $594,644.00 |
| Illinois state transfer stamp (1,190 increments at $0.50) | −$595.00 |
| DuPage County transfer stamp (1,190 at $0.25) | −$297.50 |
| City of Naperville stamp (1,190 at $1.50 = $1,785.00), bought by the buyer | $0.00 to you |
| Property tax credit to the buyer ($12,190.20 for the year, 273 of 365 days) | −$9,117.60 |
| Real estate attorney, flat fee | −$650.00 |
| Subtotal, the costs known or quoted in advance | −$10,660.10 |
| Price minus those costs | $583,983.90 |
| Mortgage payoff | your lender payoff quote |
| Title, settlement, and recording | your closing agent quote |
| Prep, repairs, and concessions | your choices |
| Commission you negotiate | $5,946.44 per percentage point |
| Your net proceeds | subtract the four lines above |
Two things in that sheet are worth sitting with. First, $1,785.00 of transfer tax appears on the closing statement and none of it is yours. A national page that deducts a percentage of the price for transfer taxes would have taken that money off your side of the ledger, when in Naperville the buyer, not you, is the one who buys that stamp. Second, the property tax credit is more than four fifths of that subtotal, and it is driven by the calendar. Close on March 31 instead of September 30 and the same home credits $3,005.80 rather than $9,117.60. If that home sat on the Will County side of Naperville, where Ownwell reports a 2.35 percent median effective rate, the annual bill would be about $13,974 and the same September 30 credit about $10,452, roughly $1,330 more.
For context on the gap between asking and getting: Redfin reported a median 43 days on market and a sale-to-list ratio of 100.2 percent for Naperville over the three months ending May 2026. The distance between your list price and your contract price is usually small. The distance between your contract price and your net is not.
Worked example: a $250,000 Naperville condo
At $250,000, the seller costs you can pin down in advance come to $4,858.22, about 1.94 percent of the sale price. The percentage goes up as the price goes down, because a flat attorney fee does not shrink with the sale.
$250,000 is a real Naperville number, not a round one picked for convenience. The Waterfront Estates page lists a price range of $225,000 to $266,000 for its attached homes, built between 1984 and 1986, in the south part of the city. Same rate, same closing date, same attorney fee as the example above.
| Line | Amount |
|---|---|
| Sale price | $250,000.00 |
| Illinois state transfer stamp (500 increments at $0.50) | −$250.00 |
| County transfer stamp (500 at $0.25) | −$125.00 |
| City of Naperville stamp (500 at $1.50 = $750.00), bought by the buyer | $0.00 to you |
| Property tax credit to the buyer ($5,125.00 for the year, 273 of 365 days) | −$3,833.22 |
| Real estate attorney, flat fee | −$650.00 |
| Subtotal, the costs known or quoted in advance | −$4,858.22 |
| Price minus those costs | $245,141.78 |
| Commission you negotiate | $2,500.00 per percentage point |
The lesson at this price point is the flat fee. A $650 attorney is 0.11 percent of a $594,644 sale and 0.26 percent of a $250,000 one. Flat costs bite harder on smaller sales, which is one reason a single percentage-of-price rule of thumb misleads at both ends of the Naperville market.
Transfer stamps at other Naperville prices
Transfer stamps are the one seller cost you can look up rather than estimate. The seller side is $0.75 per $500 of price, state plus county, which is $1.50 per $1,000. The buyer side, the City of Naperville stamp, is $1.50 per $500. Both are counted per $500 or fraction of $500, so a price that is not an even multiple of $500 rounds up.
| Sale price | $500 increments | Illinois state | County | Seller total | City stamp (buyer pays) | 1% of price |
|---|---|---|---|---|---|---|
| $250,000 | 500 | $250.00 | $125.00 | $375.00 | $750.00 | $2,500.00 |
| $400,000 | 800 | $400.00 | $200.00 | $600.00 | $1,200.00 | $4,000.00 |
| $500,000 | 1,000 | $500.00 | $250.00 | $750.00 | $1,500.00 | $5,000.00 |
| $594,644 | 1,190 | $595.00 | $297.50 | $892.50 | $1,785.00 | $5,946.44 |
| $750,000 | 1,500 | $750.00 | $375.00 | $1,125.00 | $2,250.00 | $7,500.00 |
| $1,000,000 | 2,000 | $1,000.00 | $500.00 | $1,500.00 | $3,000.00 | $10,000.00 |
A single-family home in Hidden Valley Estates, where the neighborhood page lists a range of $450,000 to $600,000 for homes built in 1991 and 1992, sits between the third and fourth rows. To find where your own address lands, browse Naperville neighborhoods.
One caution, because it is circulating. You may see the Illinois state rate quoted elsewhere as $0.75 per $500, sometimes described as a July 2026 increase. That figure is real but it means something else: it is the combined state and county stamp price, sold as a single stamp at closing. The state rate itself is $0.50 per $500 under 35 ILCS 200/31-10 and has not changed. A 2025 proposal that would have added a new transfer tax across the collar counties stalled in the Illinois House and never passed, and the transit funding package that did pass in October 2025 was funded without it. Because rates and payer rules can change, confirm both with the City of Naperville and your closing attorney before you rely on them.
Estimate your own net proceeds
The calculator below runs exactly the arithmetic in the two worked examples, on your numbers instead of the examples. It computes the three transfer stamp and property tax lines for you from the rates and the closing date, starts the attorney fee at the figure most commonly quoted locally, and leaves the rest as inputs, because those are the ones only you and your closing agent can supply. Every field is editable, including the ones it prefills.
Everything runs inside your browser. Nothing you type is sent anywhere, stored, or shared. Treat the result as an estimate for planning, not as a promise of a sale price or a net amount, and confirm the tax and municipal details with a tax professional or the City of Naperville.
Your estimate
An estimate for planning, not a promise of a sale price or a net amount. Transfer stamps are counted per 500 dollars of price or fraction of 500. The City of Naperville stamp is shown for reference only and is bought by the buyer under city ordinance, so it is not subtracted. Confirm rates, payer rules, and property tax proration with the City of Naperville, your closing attorney, or a tax professional.
What a net sheet cannot tell you, and who can
Three lines on the sheet are not knowable from public data, and this page will not pretend otherwise.
- The commission you negotiate. It is not set by law and is fully negotiable. Following the 2024 National Association of Realtors settlement, offers of buyer-agent compensation can no longer be published on the MLS, a listing agent must have your prior written approval before any such offer is made or paid, and any contribution you choose to make is a separate negotiation from your listing-side rate. Ask for the rate in writing before you sign anything. Each percentage point on a $594,644 sale is $5,946.44.
- Title, settlement, and recording charges. The closing agent quotes these for your price and your file. There is no published Naperville figure, so ask for the quote rather than accepting a percentage from a national page.
- Prep, repairs, and negotiated credits. These are the lines you control. Some sellers spend before listing, for example on basement waterproofing and foundation work; others end up crediting the buyer after an inspection turns something up, which is common with radon results from a firm like Reliable Radon Inspections or Heritage Radon. Either way it lands on the net sheet, before or after the offer.
There is one more line that never appears on a closing statement and still comes out of the same money: the move itself. Whether you use a specialty moving company or a full-service mover, get the quote while you are still deciding on a list price rather than after you have accepted an offer. Listing these businesses is not a recommendation or a vetting; they are Naperville-area companies in the site directory, and you should get more than one quote.
Where your sale fits. If you are leaving Naperville rather than simply selling, the sequence changes and so does the sheet. Read downsizing in Naperville if the next place is smaller, selling an inherited or probate home if you are an executor or an heir, selling to retire in Florida or Arizona if the move is a retirement, or relocating from Naperville if a transfer or PCS orders set the deadline. All four start from the same place: selling a home in Naperville.
