Net proceeds are what remains for the seller after every deduction the sale carries, and the calculation is a disciplined subtraction exercise using rates any owner can verify. Start with the expected price. Deduct commission at 5 to 6 percent (National Association of Realtors, 2025). Deduct seller closing costs at 1 to 2 percent. Deduct the inspection concession you realistically expect, inside the 20,000 to 50,000 dollar range observed on aging island inventory. Deduct carrying costs at 5,000 to 10,000 dollars a month for the months you realistically expect to wait. The research ledger performs exactly this exercise on a 1,100,000 dollar sale and lands in the low to mid 900,000 dollar range (Frontier Capitals, 2026). A mortgage payoff, where one exists, is then subtracted from that remainder to reach the cash the seller actually receives.
Two habits separate a useful calculation from a comforting one. The first is to calculate per route, not per property: the same home produces one net through a listed sale and a different net through a direct sale, because the deduction lines belong to the route. The second is to use ranges and then a realistic middle, rather than the friendliest end of every range at once. Commission research showing the average buyer agent share at 2.40 percent in early 2025 (Redfin, 2025) is a reminder that headline percentages persist in practice, so a worksheet that assumes they will vanish is a worksheet that will disappoint.
The worked examples in this report use the 1,100,000 dollar ledger from the research and the 1,500,000 dollar illustration derived from it, in which deductions of roughly 125,000 to 230,000 dollars leave a listed net near 1,270,000 to 1,375,000 dollars before taxes (Frontier Capitals, 2026). Any owner can substitute personal figures into the same five steps and obtain a personal answer in under an hour, provided the mortgage balance and the insurance position are pulled from real statements rather than from memory.
Key Findings
- The net calculation deducts commission, closing costs, concessions and carrying costs from price, in that order (Frontier Capitals, 2026).
- Commission runs 5 to 6 percent and closing costs 1 to 2 percent, a combined 6 to 8 percent on the listed route (National Association of Realtors, 2025).
- The worked 1,100,000 dollar ledger nets in the low to mid 900,000 dollar range after a normal listed cycle (Frontier Capitals, 2026).
- At 1,500,000 dollars, the derived illustration leaves 1,270,000 to 1,375,000 dollars before taxes (Frontier Capitals, 2026).
- Deed and payoff records ground the final step, since the recorded transfer and any lien payoff close the calculation (Collier County Clerk of the Circuit Court, 2026).
What are the five steps of the worksheet?
Step one: fix the price assumption from evidence. Use recorded comparable sales and recent sold data for the ZIP (Redfin, 2026), not an automated estimate and not the highest asking price on the street. Owners of older homes should also run the land comparison, since the sample shows older homes averaging 27.0 percent of comparable new build prices with builders taking 78.4 percent of sampled homes (Frontier Capitals, 2026). If the builder route is realistic for the parcel, calculate that net as a separate column from the start.
Step two: deduct the percentage lines. Commission at the rate you have actually negotiated or, before negotiation, at the full 5 to 6 percent range (National Association of Realtors, 2025). Closing costs at 1 to 2 percent. On a 1,100,000 dollar price those two lines remove 66,000 to 88,000 dollars combined, which matches the research statement that the combined take exceeds 65,000 dollars on a 1,000,000 dollar transaction. Step three: deduct the expected concession. For a sound home with documented roof and panel, use the low end of the 20,000 to 50,000 dollar range. For a home with known findings, use the middle or top, and be honest, because the inspection will find what you already know. Disclosure duties for known material defects (Florida Supreme Court, 1985) mean known findings belong in the worksheet whether or not they are volunteered early.
Step four: deduct carrying costs for realistic time. Listed older homes commonly take 60 to 120 plus days, and an after season start can run six to nine months. At 5,000 to 10,000 dollars a month, insurance is a major component on the island, where the Florida average premium is 8,471 dollars (Insurance.com, 2026) and premiums rose 75 percent between 2021 and 2025 (Coalition for an Insurable Future, 2026). Step five: deduct any mortgage payoff and other recorded amounts that must clear at closing, which the deed and lien record will confirm (Collier County Clerk of the Circuit Court, 2026). What remains, before taxes, is the net proceeds figure. Tax is estimated separately under federal guidance (Internal Revenue Service, 2026), as the companion report on capital gains taxes when selling explains.
How does the worksheet look on the two worked prices?
On 1,100,000 dollars: commission removes 55,000 to 66,000 dollars. Closing costs remove 11,000 to 22,000 dollars. A mid range concession removes about 30,000 dollars. Four to six months of carrying removes 20,000 to 60,000 dollars. The remainder, before any mortgage payoff and before taxes, sits in the low to mid 900,000 dollar range the research reports (Frontier Capitals, 2026). On 1,500,000 dollars: commission removes 75,000 to 90,000 dollars, closing costs remove 15,000 to 30,000 dollars, concessions remove 20,000 to 50,000 dollars and three to six months of carrying removes 15,000 to 60,000 dollars, leaving 1,270,000 to 1,375,000 dollars before taxes.
Notice what the comparison teaches. The higher priced home loses more dollars to the same percentages, and it does not necessarily lose them faster, since higher priced older homes can wait longer for their buyer. Percentage discipline therefore matters more, not less, as price rises. Owners can test sensitivity by moving one assumption at a time: a single extra month of waiting at the top carrying rate costs 10,000 dollars, which is larger than the entire closing cost range on many sales. That sensitivity is why the report on how much money a seller keeps after a 1,500,000 dollar sale presents its answer as a band rather than a point.
Older home upkeep belongs in the worksheet as a pre sale line where spending is planned. Improving and maintaining older homes costs more for new owners than for long term owners (U.S. Census Bureau, 2023), and buyers will price expected work into offers, so an owner should either budget the work or budget the concession it will produce, but not neither. Double counting is the opposite error: do not deduct both a full repair programme and a full concession for the same findings.
A sensitivity table, even a rough one, is worth adding once the basic worksheet exists. Run the listed column three times: once with friendly assumptions, once with the middle of every range and once with the slow, concession heavy outcome the ranges allow. The spread between the friendly and heavy versions on a 1,100,000 dollar sale can exceed 80,000 dollars, and seeing that spread in writing changes how an owner negotiates. A seller who knows the heavy version still funds the next home can negotiate calmly. A seller who has only ever seen the friendly version experiences every concession demand as a crisis. The ranges in this series exist precisely so the heavy version can be priced in advance: commission at the top of 5 to 6 percent, concessions at the top of the observed range, carrying at the top monthly figure across a long season (Frontier Capitals, 2026; National Association of Realtors, 2025).
The worksheet should also carry a date. Assumptions decay. A commission quote from last season, an insurance premium from before the latest renewal, or a comparable sale from before a rate shift can each move the answer by thousands of dollars, and a worksheet built on stale inputs looks precise while being wrong. Refresh the price assumption from recent sold evidence (Redfin, 2026), refresh the payoff from a current lender statement, and refresh the insurance figure from the current declaration before any offer is judged against the result. Ten minutes of refreshing protects the whole exercise.
How should the direct route column be calculated?
Give the direct route its own column and fill it honestly. Price: the direct offer figure. Commission: zero under the model described in this series. Seller closing costs: zero. Concessions and repair credits: zero, because there is no inspection renegotiation cycle, which removes both the 10,000 to 30,000 dollar credit pattern and the 20,000 to 50,000 dollar concession range. Carrying: weeks rather than months, since a direct closing completes in 7 to 21 days, with a leaseback available if the household needs post closing time. Mortgage payoff: the same recorded balance as in the listed column (Collier County Clerk of the Circuit Court, 2026).
The two columns will rarely favour the same route on gross price, and they frequently favour the direct route on net and on certainty, which is the comparison the worksheet exists to reveal. Sellers should also record a risk note beside each column: the listed column carries timing risk, contract failure risk and concession risk, while the direct column carries the simpler risk that the offer itself is below what patient marketing might have produced. Writing the risks down prevents the arithmetic from pretending to a precision it does not have. Owners who want the hidden lines included can add them from the report on hidden expenses that reduce profits, and can review route coverage on the coverage page.
What are the most common calculation errors?
The first error is calculating from asking price rather than from a realistic closing price. Every percentage line then inherits the optimism. The second error is omitting carrying cost entirely, as though months were free, when the island range is 5,000 to 10,000 dollars a month. The third is treating tax as part of the closing net or ignoring it altogether. Tax follows the gain calculation in the federal guidance (Internal Revenue Service, 2026) and belongs in a separate estimate made at the same sitting. The fourth is forgetting the mortgage payoff step and reporting the pre payoff remainder as spendable cash. The fifth is comparing a listed gross with a direct net, the single most common way owners talk themselves into the worse outcome.
A useful discipline is to have another person check the worksheet against source documents: the mortgage statement for the payoff, the insurance declaration for the premium inside carrying cost, and the comparable sales printout for the price assumption. Thirty minutes of checking protects a six figure conclusion.
What does selling off market protect on Marco Island?
In worksheet terms, the off market route protects the net by deleting lines rather than by inflating price. Privacy protects the process itself: zero showings, zero open houses and no public marketing period. Flexibility protects the carrying line: 7 to 21 days to closing against 60 to 120 plus listed days, with a leaseback to cover a move. The commission line of 5 to 6 percent is deleted, worth 55,000 to 66,000 dollars on a 1,100,000 dollar sale. The closing cost line of 1 to 2 percent is deleted with it, keeping the combined 6 to 8 percent in the seller column. The concession lines are deleted: no 10,000 to 30,000 dollar repair credits and no 20,000 to 50,000 dollar inspection concessions.
Frontier Capitals is a wholesaler that sources off market deals to builders, and that disclosure belongs on the worksheet too: the direct column exists because a builder will take the property as it stands, and the owner should verify any buyer through proof of funds and recorded deeds before treating the direct net as certain.
Methodology and limitations
The worksheet in this report is the research ledger method for this study, built from the documented rates in the source pool: commission of 5 to 6 percent, seller closing costs of 1 to 2 percent, concessions of 20,000 to 50,000 dollars and carrying costs of 5,000 to 10,000 dollars a month (Frontier Capitals, 2026; National Association of Realtors, 2025). The 1,500,000 dollar illustration is derived arithmetically from the same rates and is labelled an illustration. The wider sample covers 37 pre-1981 homes in 34145 and is not a census.
Personal worksheets will differ where commission is negotiated, where a home carries no mortgage, where insurance sits above the state average or where timing beats the ranges used here. Tax is excluded from the net proceeds definition in this report and must be estimated separately. Nothing here is an appraisal or a guaranteed outcome for a specific property.
Keep the finished worksheet with the sale documents after closing and compare it with the actual settlement statement. The comparison is the best education a seller can buy, and in this case it is free. Most owners discover that one assumption did most of the damage or delivered most of the accuracy, usually the time estimate or the concession allowance, and that discovery makes the next transaction, a purchase, an estate sale for a relative or a later move, measurably better judged. Sellers who complete that review also gain a clear answer when neighbours ask what the sale really produced, an answer based on the statement rather than on the announcement price (Collier County Clerk of the Circuit Court, 2026). In a market where gross prices are public and nets are private, that clarity is a genuine advantage.
Conclusion
Calculating net proceeds in Marco Island takes five honest subtractions and two columns, one per route, and the research ledger shows why the exercise matters: a 1,100,000 dollar listed sale nets in the low to mid 900,000 dollar range, while the deductions at 1,500,000 dollars reach 125,000 to 230,000 dollars (Frontier Capitals, 2026). An owner who builds the worksheet before choosing a route will negotiate from the number that actually funds the next chapter of life.

Frequently Asked Questions
What is the formula in one line?
Price, minus commission, minus closing costs, minus expected concessions, minus carrying costs for realistic time, minus any mortgage payoff, equals net proceeds before taxes.
Which deduction do sellers most often forget?
Carrying cost. At 5,000 to 10,000 dollars a month over a 60 to 120 plus day listed period, it can exceed the entire closing cost line, yet many home made worksheets leave it at zero.
Should taxes be deducted in the worksheet?
Estimate them at the same sitting but keep them as a separate line after net proceeds, because tax follows gain over basis under federal guidance (Internal Revenue Service, 2026) rather than the closing statement alone.
How do I find my mortgage payoff figure?
Use the payoff statement from your lender rather than the balance on a monthly statement, and remember that recorded liens clear through the closing record (Collier County Clerk of the Circuit Court, 2026).
Does the direct route always produce a higher net?
Not always. It deletes commission, closing costs, concessions and most carrying time, so its net is higher than the listed net whenever the direct price is within the deduction band of the listed price. The worksheet shows the exact crossover for your figures.
