Analysis & insights
On a $450,000 sale, you'll net approximately $128,250 after selling costs (9.3%). Your gain of $91,250 falls within the IRS Section 121 exclusion (up to $250K single / $500K married) — no federal capital gains tax owed. Selling costs in the US typically run 7-10% of sale price (agent commission + closing + transfer taxes + concessions).
Tax-free gain
Gain under $250K (single) / $500K (married) — typically tax-free if it's your primary residence for 2 of last 5 years.

Key insights
Section 121 — your biggest tax friend
Primary-residence sales get a $250K (single) / $500K (married) exclusion on capital gain, IF you've owned + lived in the home 2 of the last 5 years. Worth verifying eligibility.
Selling costs are massive
Agent commission (5-6%), transfer/recording taxes (0.5-2%), title fees, attorney, closing costs, possibly buyer concessions. Plan for 7-10% of sale price.
Recommended actions(3)
Interview at least 3 listing agents
High priorityCommission rates are negotiable (often 4-5.5% total in 2024+ after settlement changes). 1% saved on a $500K sale = $5,000 directly to you.
Track capital improvements for basis
High priorityAdd up major improvements (kitchen, bath, additions, HVAC, roof, landscaping). These raise your cost basis and reduce taxable gain. Even $50K extra basis can save $7,500-10,000 in tax.
Time the sale strategically
Medium prioritySpring listings (March-May) historically sell 5-10% higher than fall/winter. Worth waiting if you have flexibility.
What is Home Sale Net Proceeds?
The cheque you receive when selling a house bears little relation to the price on the sign. Between the two sit agent commission, closing costs, the outstanding mortgage, and possibly capital gains tax — and sellers routinely overestimate their proceeds by tens of thousands.
The confusion comes from mixing two different subtractions. Paying off your mortgage reduces the cash you receive but is not a cost — you are returning borrowed money. Commission and closing costs are genuine costs that reduce both your cash and, importantly, your taxable gain.
Keeping those separate is what makes the arithmetic honest, and it is also what most quick estimates get wrong.
The formula — how to calculate Home Sale Net Proceeds
- Selling costs
- = agent commission plus closing costs — typically 6–10% combined
- Mortgage payoff
- = reduces your cash but is NOT a cost; it is repayment of borrowed money
- Adjusted basis
- = what you paid plus capital improvements — not repairs
Gain is measured from the amount realised, not the headline sale price. Omitting selling costs from that calculation overstates the gain by the full amount of the commission — a common error that inflates the tax estimate substantially.
Step-by-step example
- 01Sale price $450,000. Purchase price $320,000. Mortgage balance $280,000. Agent commission 5.5%, closing costs 2%, capital improvements $5,000. Single filer, lived there five years.
- 02Commission: $450,000 × 5.5% = $24,750. Closing costs: $450,000 × 2% = $9,000. Total selling costs $33,750.
- 03Amount realised: $450,000 − $33,750 = $416,250.
- 04Adjusted basis: $320,000 + $5,000 = $325,000.
- 05Gain: $416,250 − $325,000 = $91,250.
- 06The single-filer exclusion is $250,000, which comfortably covers this — taxable gain is zero and no capital gains tax is due.
- 07Net proceeds: $450,000 − $33,750 selling costs − $280,000 mortgage = $136,250 before the $3,000 of staging and moving, so roughly $133,250 in hand.
- 08Note the two different numbers: the property produced a $91,250 gain, but only $133,250 arrives — because $280,000 of the sale price repaid a loan rather than becoming income.
The exclusion that removes tax for most sellers
Section 121 excludes up to $250,000 of gain for a single filer and $500,000 for a married couple filing jointly. It is the largest tax break most households ever use, and it means the majority of home sales generate no capital gains tax at all.
Two tests must be met. Ownership: you owned the home for at least two of the five years before the sale. Use: it was your main residence for at least two of those same five years. The two years need not be continuous, and the exclusion can generally be claimed once every two years.
Partial exclusions are available where the sale was forced by a change in employment location, health, or certain other unforeseen circumstances, prorated by how much of the two-year requirement you met. Someone who owned for one year before an unavoidable relocation may claim half.
The exclusion applies to the gain, not the sale price. A $900,000 sale of a home bought for $300,000 produces a gain well above $250,000, so a single seller in that position does owe tax on the excess.
Depreciation recapture if the property was ever let
Any depreciation claimed while the home was a rental is recaptured on sale and taxed at up to 25%, and the Section 121 exclusion does not shelter it. This catches out owners who rented a property for a few years before moving back in, because the exclusion appears to cover the whole gain while the recapture sits outside it.
Improvements add to basis; repairs do not
This distinction is worth real money at sale, and it depends on records kept over years.
A capital improvement adds value, prolongs the property's life, or adapts it to a new use — a new roof, an extension, a replaced heating system, a rewire, landscaping that changes the site. These increase your basis and therefore reduce your gain.
A repair returns something to its previous condition — fixing a leak, repainting, replacing a broken window pane. These do not add to basis, however necessary they were.
The practical consequence is that a receipt kept for twenty years can be worth thousands at sale. On a gain that exceeds the exclusion, every $10,000 of documented improvement saves $1,500 at the 15% rate. Most sellers cannot produce those records, and pay accordingly.
Where the sale price actually goes
| Item | Typical range | Reduces gain? |
|---|---|---|
| Agent commission | 5–6% of sale price | Yes |
| Closing costs, seller side | 1–3% | Yes |
| Mortgage payoff | Whatever remains | No — repayment, not a cost |
| Capital improvements | Varies | Yes, via basis |
| Repairs before sale | Varies | No |
| Staging and moving | $2,000–$6,000 | No |
Commission structures have been changing following litigation over how buyer-agent compensation is negotiated. Treat the rate as negotiable and confirm the actual figure rather than assuming a historical norm.
What a quick estimate misses
Sellers usually calculate sale price minus mortgage and stop there. Several items sit between that number and the cheque.
Prorated property tax is settled at closing, and depending on the local billing cycle you may owe a portion for the period you owned the property this year. The same applies to HOA dues.
Repairs demanded after the buyer's inspection are a common surprise. Buyers frequently negotiate a credit or a price reduction after inspection, and budgeting nothing for it is optimistic.
A mortgage payoff figure is not the same as your last statement balance — it includes interest accrued to the settlement date, and occasionally a prepayment charge on older loans.
Finally, if you are buying onward, the proceeds are what fund the next deposit. Overestimating them by $30,000 can unravel a chain, which is the practical reason to run this calculation conservatively rather than optimistically.
Key considerations
- Measure gain from the amount realised — sale price less selling costs — not the headline price.
- The mortgage payoff reduces your cash but is not a cost and does not reduce your gain.
- Keep records of capital improvements; they reduce gain and most sellers cannot produce them.
- Section 121 excludes $250,000 single or $500,000 joint if you meet the ownership and use tests.
- Depreciation from any rental period is recaptured separately at up to 25%.
- Ask your lender for a payoff quote to a specific date rather than using a statement balance.
- Budget for post-inspection repair credits, which are common.
- Agent commission is negotiable, and the market convention has been shifting.
Common mistakes to avoid
- Calculating gain from the sale price without deducting commission and closing costs.
- Treating the mortgage payoff as a cost that reduces taxable gain.
- Confusing repairs with capital improvements when computing basis.
- Assuming the exclusion covers everything when depreciation recapture sits outside it.
- Using the last statement balance rather than a dated payoff figure.
- Estimating proceeds optimistically and building an onward purchase on the number.
- Forgetting prorated property tax and HOA dues settled at closing.
