Updated November 2026. A profit formula for three kinds of sale: your home, a flip and a rental. IRS and NAR pages read November 6, 2026. Every worked number is an example.
A real estate profit calculator takes the sale price, subtracts commission and selling costs, then subtracts what you have in the property. As of November 2026, on the $417,500 US median price, our example shows $106,625 on a home, $29,625 on a flip and $151,625 on a rental, before tax. The tax rules are what split them.
Curious what your listing fee does to that line? Beycome Basic is from $99 in most states, with $0 due to Beycome at closing.

Three rules of thumb
- Profit and cash at closing are different numbers. Your loan payoff changes one and not the other.
- Commission comes off the gross price, so it bites hardest when your margin is thin.
- A main home may be tax-free up to a limit. A flip and a rental play by other rules.
Selling your own home and just want the closing-day number? Our home sale proceeds calculator is built for that. This page covers the wider question, including investment property, and it starts with a line most tools bury: the commission. For the commission math on its own, see our commission calculator guide and results at $300K, $400K and $500K.
How do you calculate profit on real estate?
Use one line:
Profit = sale price − selling costs − what you have in it.
Sale price. Use a realistic number from recent nearby sales, not your list price. A free CMA and home value report gets you started.
Selling costs. Listing fee, any buyer-agent pay you agree to, transfer tax, title and legal costs, and credits you give the buyer. Commissions count here, per IRS Publication 523.
What you have in it. Purchase price, purchase costs and improvements. On a flip, add your rehab and holding costs. On a rental, take off the depreciation you’ve claimed.
Notice what’s missing: your mortgage. A loan doesn’t change your profit. It only changes your cash at closing, which is sale price minus selling costs minus payoff. Want to run it with live inputs? Try the Beycome Title home profit calculator or our net proceeds worksheet.
What does the profit look like on a home, a flip and a rental?
Same sale price, three stories. We used the $417,500 median from NAR’s September 2026 report. Selling costs here assume an example 2.5% listing fee, 2.5% buyer-agent pay and $5,000 for everything else.
| Line | Main home | Six-month flip | Rental held 10 years |
|---|---|---|---|
| Sale price | $417,500 | $417,500 | $417,500 |
| Selling costs (example) | $25,875 | $25,875 | $25,875 |
| Purchase price | $260,000 | $300,000 | $280,000 |
| Added costs | $25,000 improvements | $5,000 purchase, $45,000 rehab, $12,000 holding | $20,000 improvements |
| Depreciation claimed | None | None | $60,000 (lowers your basis) |
| Profit before tax | $106,625 | $29,625 | $151,625 |
| With a $99 listing instead of 2.5% | $116,963.50 | $39,963.50 | $161,963.50 |
Look at the flip column. The same $10,338.50 that nudges the homeowner’s profit lifts the flipper’s by about 35%. Thin margins feel fees the most. That’s why investors watch this line so closely.
Say the homeowner still owes $150,000. Cash at closing is $241,625, even though the profit is $106,625. Mixing up those two numbers is the most common way people fool themselves.
How does commission change your real estate profit?
It comes off the gross price, before anything else, and it’s the same whatever you still owe. A seller with $50,000 of equity pays the same percentage as one with $300,000. It’s also one of the few lines you can actually negotiate.
Every percentage here is an example. Commissions are not set by law or NAR rules and are fully negotiable. Sellers choose whether to offer buyer-agent compensation, and how much, and since August 17, 2024 such offers can’t be shown on the MLS. Redfin reported an average buyer’s agent rate of 2.42% in the third quarter of 2025. That’s an average, not a rule.
So run three versions: no buyer-agent pay, a flat amount you’d accept, and a percentage in case a buyer asks in an offer. Written buyer agreements now spell out what that agent expects, per NAR’s consumer guide. Before you sign anyone, here’s how to check a brokerage’s fees are transparent.
Sell smarter
List your home on the MLS from $99
A flat fee instead of a percentage, and $0 to Beycome at closing. You stay in control of your sale.
Sell your home →Buy smarter
Get up to 2% back at closing
On homes listed by other agents, Beycome credits you up to 2% of the price at closing (1% kept, $1,499 minimum; not on FSBO homes or homes listed by Beycome sellers).
Buy a home →Credits land in the same place. A buyer may ask for one instead of a higher price, and their lender caps it. Fannie Mae limits financing concessions at 3% to 9% on a main home, depending on the down payment, and 2% on an investment property. Our guide to comparing selling costs shows that side by side.
Our own number is simple on purpose. One flat price, which doesn’t grow with the sale price, and $0 due to Beycome at closing. You answer the questionnaire and a complete file goes on the MLS within 2 business days. Over 22,000+ homeowners have saved over $225 million this way (Beycome internal data, October 2026). Your result depends on your price and your choices.
How is real estate profit taxed?
This is general information, so check it with a tax pro before you rely on it.
Your main home. You may exclude up to $250,000 of gain, or $500,000 on a joint return, if you meet the ownership and use tests (IRS Topic 701). Our $106,625 example would likely owe nothing.
A flip. Sold within a year, the gain is short-term and taxed as ordinary income (IRS Topic 409). Regular flipping can also count as a business, with more tax on top. So $29,625 is not what you keep.
A rental. You’ve been deducting depreciation over 27.5 years, and some of that comes back at sale. In our example, the $60,000 claimed falls under the unrecaptured section 1250 gain rate, which tops out at 25%, so up to $15,000. The other $91,625 is long-term gain. At an example 15% rate, that’s $13,743.75. The two come to about $28,744, before any state tax.
Rental owners sometimes defer all of that with a 1031 like-kind exchange. You have to identify the replacement within 45 days and close within 180. The Internal Revenue Service has the full rules, and the deadlines are strict.
What mistakes make a profit calculator wrong?
- Typing the list price instead of a realistic sale price.
- Subtracting the mortgage and calling the result profit.
- Using one combined commission rate when the two sides are now separate deals.
- Forgetting a minimum fee, a closing-day add-on or a credit you’ll likely give after inspection.
- Leaving out holding costs on a flip: interest, insurance, taxes and utilities.
- Ignoring depreciation on a rental, even if you never claimed it on purpose.
Keep your inputs in one sheet, with a tab per offer. When a real offer arrives, you can rerun it in minutes and compare nets before you counter. If you’re on the buyer’s side of the paperwork, the Consumer Financial Protection Bureau explains the closing documents.
Real estate profit calculator questions
How do I calculate profit on a real estate sale?
Take the sale price, subtract selling costs, then subtract what you have in the property: purchase price, purchase costs and improvements.
Is real estate commission calculated on the list price or the sale price?
On the sale price, in most listing agreements. Use a realistic sale price from recent nearby sales when you run the numbers.
Does my mortgage balance change my profit?
No. It changes your cash at closing, not your profit. The commission stays the same whatever you owe.
How do I calculate a flat fee in a commission calculator?
Set the listing percentage to zero and subtract the flat fee by hand, for example $99 for Beycome Basic in most states.
Are real estate commissions tax deductible?
They’re selling expenses that reduce your amount realized when you figure gain (IRS Publication 523). Ask a tax pro how that applies to you.
How much profit is a good flip?
There’s no official number. Work out the profit after selling, rehab and holding costs, then compare it with the risk and your time. Leave room for overruns.
Do I pay tax when I sell a rental property?
Usually, on the gain. Depreciation you claimed is taxed at up to 25%, and the rest at capital gains rates, unless you defer it with a 1031 exchange.
All purchase prices, costs, depreciation and tax rates in the examples are illustrations, not predictions. Commission figures are examples only; commissions are not set by law or NAR rules and are fully negotiable; sellers choose whether to offer buyer-agent compensation; such offers can’t be shown on the MLS since August 17, 2024.
Prices as of November 2026: Basic from $99 in most states, $129 in California and Illinois; Concierge $1,399. “$0 at closing” means no Beycome fee at closing; taxes, title and any buyer-agent pay you agree to still apply. Go-live time applies to complete, correct files. General information, not tax or legal advice; rules vary by state and MLS.
