Realtor Profit Calculator
A gross commission check feels great until the broker takes a cut and the bills come due. This calculator turns a sale price and commission rate into true net profit: gross commission, the brokerage split, deal expenses, and the margin left over. It also runs an investor mode for flips, with total cost, ROI, and monthly profit in one view.
Two tools live under one roof here. Agent mode answers “what did I actually earn on this deal” after the split and the spending. Investor mode answers “did this flip make money” after purchase, renovation, holding, and resale costs. Enter your numbers and press Calculate; nothing computes until you do.
Agent mode finds net profit on one deal. Investor mode finds flip profit, ROI, and monthly profit.
Quick Answer
On a $500,000 sale at a 3% commission, the gross is $15,000. After a 20% brokerage split ($3,000) and $1,500 in deal expenses, the agent keeps $10,500, a 70% margin. In investor mode, buying at $150,000, spending $40,000 on renovation, and selling at $250,000 leaves a $37,000 flip profit, an 18.93% ROI, or $9,250 per month over four months.
How to use the realtor profit calculator
Pick a mode, fill in the deal numbers, and press Calculate. The results stay hidden until you run a calculation, and the Reset button restores the example values any time.
Agent mode. Enter the property sale price and your commission rate, then the percentage your brokerage keeps and your out-of-pocket deal expenses: marketing and photography, MLS dues, mileage to showings, transaction coordination, office fees. The tool returns gross commission, the brokerage deduction, total expenses, net profit, and profit margin. If you are on a 70/30 commission split, enter 30 as the brokerage split, because the field asks what the brokerage keeps, not what you keep.
Investor mode. Enter the purchase price, purchase closing percentage, renovation budget, monthly holding cost with the number of months held, the expected sale price, the sale closing percentage, and the agent commission on the resale. You get total cost, net proceeds, flip profit, ROI, and monthly profit. Every figure the tool shows can be copied or shared straight from the results box, which is handy when a broker or partner asks how you got your number.
The formulas behind the calculator
Agent mode runs four short steps. First the gross, then each deduction, then the margin on what is left.
Gross commission = Sale price × (Commission rate ÷ 100)
Brokerage deduction = Gross commission × (Brokerage split ÷ 100)
Net profit = Gross commission − Brokerage deduction − Expenses
Profit margin = (Net profit ÷ Gross commission) × 100
Investor mode prices the whole project, both ends of it. Closing costs are percentages, so they scale with the prices they attach to.
Total cost = Purchase + (Purchase × Purchase closing %) + Renovation + (Monthly holding × Months)
Net proceeds = Sale price − (Sale × Sale closing %) − (Sale × Agent commission %)
Flip profit = Net proceeds − Total cost
ROI = (Flip profit ÷ Total cost) × 100
Monthly profit = Flip profit ÷ Months
Worked example: one deal, both modes
Agent. You sell a home for $500,000 at a 3% commission. Gross commission = $500,000 × 3% = $15,000.00. Your brokerage takes a 20% split = $3,000.00. You spent $1,500.00 on marketing and mileage. Net profit = $15,000 − $3,000 − $1,500 = $10,500.00, a 70.00% margin. Press Calculate with the pre-filled values above and the tool returns these exact figures.
Where the $15,000 commission goes
Investor. You buy at $150,000 with 1% purchase closing ($1,500), spend $40,000 on renovation, and hold 4 months at $1,000 per month ($4,000): total cost = $195,500.00. You sell at $250,000 with 2% closing ($5,000) and 5% commission ($12,500): net proceeds = $232,500.00. Flip profit = $232,500 − $195,500 = $37,000.00, ROI 18.93%, monthly profit $9,250.00. Switch to the investor tab above and press Calculate to reproduce every line.
What competing calculators miss
Most pages ranking for realtor commission math do half the job. Commission splitters show the gross and each side’s share but never subtract what the agent actually spends to earn the deal, so the “earnings” they print are not profit. Seller net sheets are built for the person selling the house, not the agent living on the commission. And the flip calculators handle investors well but cannot tell a working agent what a listing actually pays after the brokerage cut.
This page keeps both questions in one tool. Agent mode itemizes the brokerage deduction alongside real deal expenses and turns them into a margin, which is the number that tells you whether a deal was worth the weekends. Investor mode covers the full flip (closing costs on both ends, holding costs, ROI, monthly profit). The results copy and share buttons close the loop: when a broker asks how you priced your net, you send the exact breakdown instead of a screenshot of a napkin.
What a split really costs you
Your brokerage split is usually the biggest single deduction, and small differences in it move the net more than most agents expect. On a $15,000 gross with no other expenses, the take-home before spending looks like this:
| Split (agent / brokerage) | Brokerage keeps | You keep (before expenses) |
|---|---|---|
| 50 / 50 | $7,500.00 | $7,500.00 |
| 60 / 40 | $6,000.00 | $9,000.00 |
| 70 / 30 | $4,500.00 | $10,500.00 |
| 80 / 20 | $3,000.00 | $12,000.00 |
| 90 / 10 | $1,500.00 | $13,500.00 |
Two things decide where you land on that table. New agents often start near 50/50 and graduate toward 80/20 or better as production rises, and many teams add a flat per-deal transaction fee on top of the percentage. Since the 2024 NAR settlement, commission terms are negotiated in writing and are not set by law, so the rate you enter here should be the one in your listing agreement, not a market rumor. NAR’s own settlement facts page lays out the practice changes plainly.
Reading the investor numbers honestly
ROI and monthly profit answer different questions, and a flip can pass one while failing the other. ROI measures efficiency: how hard each dollar of total cost worked. Monthly profit measures pace: how fast the project paid you back for your time. A 19% ROI over four months is a strong flip; the same 19% stretched over fourteen months is a mediocre use of capital once holding costs compound.
The silent killer in most flip math is the holding line. Every extra month adds the full monthly carrying cost and pushes monthly profit down, which is why the worked example prices four months at $1,000 rather than waving at “about a quarter.” If you hold rentals instead of flipping, pair this with a cap rate check, and when you are buying a rental property to flip later, run the purchase side there first. One more honesty note: the profit here is before income tax. Independent agents generally owe self-employment tax on net earnings too, so treat the IRS self-employment tax rules as a second calculator, not an afterthought.
Takeaways
- Commission is gross. Profit is what survives the split and the expenses, and the gap is usually thousands per deal.
- The brokerage split is the biggest deduction on most deals, so enter it before trusting any net figure.
- Set income goals on net profit per deal, not on sales volume: two agents with identical volume can differ wildly in take-home.
- On flips, price every month of holding. Time is the expense most investors underestimate.
Frequently asked questions
The commission is the gross amount a deal generates. Profit is what survives the brokerage split plus marketing, MLS, mileage, office, and admin costs. On a $15,000 gross with a 20% split and $1,500 in expenses, the real profit is $10,500, not $15,000.
New agents often start near 50/50 and move toward 80/20 or 90/10 as production rises, and many teams add a flat per-deal transaction fee. Because the split is usually the largest deduction on a deal, enter it before trusting any net figure.
Anything spent to earn the deal: photography and staging, listing advertising, MLS and association dues allocated to the deal, mileage to showings, transaction coordination fees, and CRM or office costs you track per transaction. Leave income tax out of this field and handle it separately, since most independent agents also owe self-employment tax on net earnings.
Net. Two agents with identical $1M sales volume can differ by thousands in take-home once splits and spending differ. Track net profit per deal and you know exactly how many closings your income goal requires.
Use investor mode: add purchase price, purchase closing costs, renovation, and monthly holding costs to get total cost, then subtract sale closing costs and agent commission from the sale price to get net proceeds. Flip profit is net proceeds minus total cost. The worked example above turns $195,500 of total cost and $232,500 of net proceeds into a $37,000 profit.
No. Results are before income tax. Independent agents usually owe self-employment tax on top of income tax, so set aside a share of every net profit for estimated payments.
