Phuket Property ROI Calculator Guide 2026: How to Calculate Real Returns
If you are comparing Phuket condos to a spreadsheet of stocks and bonds, you need one thing first: a single definition of ROI that matches how money actually moves. Gross yield on a brochure is not ROI. Neither is “my friend rents his villa for 300 dollars a night in February.” Real ROI is what remains after every cost you would pay whether you are having a good month or a bad one, and then how that stacks against capital growth and currency.
This guide walks through gross yield, net yield, total return (yield plus appreciation), and three fully worked examples at different price points and zones. Use it as a mental calculator before you sign anything.
What ROI means in Phuket (and what it does not)
- Cash-on-cash yield: rental income minus operating costs, relative to the money you put in (price, closing, furniture, loan down payment if any).
- Capital appreciation: change in resale value over your holding period.
- Currency effects: if your life is in euros, dollars, pounds, or another home currency, your “return” is not only baht.
Total return is the combination of annualized net cash flow and annualized price change, plus any currency effect you choose to model. Many investors focus only on yield and miss that a lower-yield asset with stronger resale liquidity can beat a high-yield headache in year five.
Gross yield: the headline number
| Concept | Formula |
|---|---|
| Gross yield | Annual gross rent ÷ Property price |
Example: If gross rent is 18,000 USD per year on a 200,000 USD unit, gross yield is 9 percent.
Gross yield is useful for quick comparison between listings. It is dangerous as a decision metric because it ignores management, vacancy, taxes, and repairs.
Net yield: the number your bank account feels
Typical operating lines for Phuket short- and mid-term rentals:
| Cost bucket | What to include |
|---|---|
| Management / program | Operator fee, admin, channel management |
| OTA and booking fees | Commissions on bookings |
| Housekeeping | Per-turnover cleans |
| Utilities | Owner-paid portions |
| Maintenance and repairs | AC service, minor fixes |
| Insurance | Contents and liability where applicable |
| Vacancy and discounting | Explicit line item, not zero |
Net yield (simple): NOI ÷ total acquisition cost.
Investors who include furniture and closing in the denominator are modeling more honestly than those who use only the developer list price.
Total return: yield plus growth
- Sum of annual net cash flows (possibly reinvested or not, depending on your model), plus
- Change in value from entry to exit, minus
- Selling costs and taxes on disposal.
Many Phuket market discussions reference multi-year price growth in the ballpark of 5-6 percent per year in stronger segments. That is not a guarantee for your unit or your year of purchase, it is a planning anchor you stress-test up and down.
Practical framing: If net yield is 6 percent and you assume 4 percent average annual appreciation over a decade, your simple mental model might land near 10 percent before currency and tax, but only if your appreciation and cost assumptions hold.
Currency: why your ROI is three-dimensional
- Baht strength against your home currency helps when you convert back.
- Baht weakness hurts on conversion.
Some investors hedge mentally by borrowing in the same currency as their balance sheet; others accept FX as part of owning a hard asset in a global tourism hub. There is no universal “right” answer, only explicit modeling versus hoping it works out.
Worked example 1: 160,000 USD one-bedroom in Bang Tao
Gross rent assumptions (illustrative): 18,000 USD per year gross (about 11.25 percent gross on price, 10.0 percent on all-in capital).
Operating costs (illustrative annual):
| Line | USD |
|---|---|
| Gross rent | 18,000 |
| Management, OTA, cleaning (example) | −5,400 |
| Utilities, minor repairs, insurance | −2,400 |
| Vacancy / discounting reserve | −2,000 |
| Net operating income (example) | 8,200 |
Net yield on all-in capital: 8,200 ÷ 180,000 ≈ 4.6 percent.
If you expect 5 percent annual appreciation on the 160,000 USD asset value over a long hold, total return (very simplified, before personal tax and sale costs) might be discussed in the high single digits, but your tax and exit costs can move that number materially.
Bang Tao note: Demand from international tourists and branded corridors can support rates, but micro-location inside the bay matters as much as the word “Bang Tao” on a map.
Worked example 2: 220,000 USD two-bedroom in Kata
Gross rent (illustrative): 24,000 USD per year (roughly 10.9 percent gross on price).
Operating costs (illustrative):
| Line | USD |
|---|---|
| Gross rent | 24,000 |
| Management + OTA + cleaning | −7,200 |
| Utilities, repairs, insurance | −3,000 |
| Vacancy reserve | −2,400 |
| NOI (example) | 11,400 |
Net yield on all-in capital: 11,400 ÷ 245,000 ≈ 4.7 percent.
Kata can combine seasonal rate strength with family repeat demand. Your net yield still depends on photography, reviews, and operator quality, not only the view.
Worked example 3: 400,000 USD pool villa in Rawai
Gross rent (illustrative): 42,000 USD per year (10.5 percent gross on price).
Operating costs (illustrative), villas often run heavier:
| Line | USD |
|---|---|
| Gross rent | 42,000 |
| Management + OTA + cleaning | −12,600 |
| Pool, garden, utilities, repairs | −8,000 |
| Vacancy / discounting | −4,200 |
| NOI (example) | 17,200 |
Net yield on all-in capital: 17,200 ÷ 450,000 ≈ 3.8 percent.
Why accept lower net yield on a villa? Some buyers prioritize personal use, larger nightly rates in peak, or landed-house optionality. Others prioritize liquidity, resale for villas can be thinner than for established condo towers. Model exit as carefully as income.

Financing: how a mortgage changes ROI math
| Item | Cash buyer | Financed buyer (illustrative) |
|---|---|---|
| Purchase price | 200,000 USD | 200,000 USD |
| Equity invested | 200,000 + costs | 60,000 down + costs |
| Annual NOI (example) | 12,000 USD | 12,000 − interest (example) |
Cash-on-cash can look higher with leverage when NOI exceeds interest, but risk rises with rate resets, vacancy, and currency on loan servicing if your income is in another currency. Always model stress: rates up 1-2 points, occupancy down 10-15 points, and a one-time capex hit (AC replacement, furniture refresh).
Taxes: where “net” splits into legal lines
For ROI modeling, add rows for:
- Withholding or corporate tax in Thailand, if applicable.
- Home-country tax on foreign rental income, credits, and filing obligations.
- Transfer taxes and fees on purchase and sale.
A property that looks like 7 percent net pretax can behave like 5 percent after tax, or a different number entirely once treaties and deductions apply.
Sensitivity: one table beats three optimistic paragraphs
| Variable | Base case | Stress case |
|---|---|---|
| Occupancy | Your realistic annual blend | 10-15 pts lower in low season |
| ADR | Blended nightly × nights | 10-20 percent discount in shoulder |
| Management + OTA | Actual quote from operator | add 1-2 pts if you switch channels |
| Maintenance | Normal reserve | one bad AC year |
If the stress case still clears your minimum acceptable net yield, you have a more durable thesis.
Holding period: ROI is not a single year
A single year’s yield is the least useful number in a property model, because the costs that decide the outcome do not fall in a single year.
Year one is not typical. It carries the transaction costs, the furnishing, the photography and the listing setup, and it usually carries a partial year of income because the unit was not lettable from January. A yield calculated on year one understates the business.
Years two to five are the real picture. Stable letting, a full year of costs, and the first maintenance items appearing. This is the range to model on, and the range an operator statement from a comparable unit will show you.
The exit year carries the second set of transaction costs. Transfer taxes, agency, and any withholding at registration. On a short hold those costs land twice against a small gain, which is why a three-year plan so often fails to clear its own friction while an eight-year one comfortably does.
A capital item will fall somewhere in the middle. Air conditioning replacement, a refurbishment cycle, or a special levy for building plant. Budgeting nothing for this across a decade is the most common modelling error, and it is the one that turns a projected return into a disappointing one.
The number to build. Total net income across the intended hold, minus both sets of transaction costs and a realistic capital reserve, expressed against the capital deployed. Then compare that to what the same capital would have done elsewhere over the same period. That is the comparison the decision actually turns on, and it is not the gross yield on the brochure.
The ROI mistakes that cost the most money
Mistake 2, Ignoring all-in capital. Furniture and closing costs can shave one to two percentage points off yield on percentage terms.
Mistake 3, Assuming peak season is the year. Annualize high, shoulder, and low months.
Mistake 4, Forgetting exit costs. Agency fees, transfer taxes, and negotiation discounts matter when you measure multi-year total return.
Mistake 5, Ignoring currency. If you do not model FX, you do not have a full picture.
How MORE Group uses ROI in real client conversations
The model is a decision tool rather than a sales one, and in practice it gets used in three ways.
To rule things out early. Most units that fail do so on the running cost rather than on the purchase price. Putting the actual annual charge in baht against a realistic occupancy removes a large share of a shortlist in an afternoon, before anyone visits anything.
To replace projections with evidence. A developer’s projected yield is a marketing figure. An operator statement from a comparable unit in the same building or corridor is evidence. Where the two disagree, the statement is the number that goes into the model, and the gap between them is itself information about the developer.
To make the trade explicit. Almost every Phuket purchase is a trade between yield and use, or between yield and liquidity. The model does not resolve that: it makes it visible, so the buyer is choosing rather than discovering. A client who decides to take a lower return for a property they will actually use has made a good decision; one who finds out afterwards has not.
What we do not do with it. Present a single number as though it were a forecast. The output is a range built on stated assumptions, and the assumptions are the part worth arguing about.
Buyer-side analysis at MORE Group carries zero commission, which is what allows a model to conclude that a unit is not worth buying.
ROI calculator inputs that must be net, not gross
| Input | Conservative default | Aggressive mistake |
|---|---|---|
| Occupancy | 62-68% annual | 85% year-round |
| Fees | 28-34% of gross | “Included” at 15% |
| Capex | 15k-25k THB / year studio | Zero maintenance |
Scenario A: long-let: use 12-month tenant math with void months. Scenario B, short-stay: demand building P&L, not developer portfolio slides. If net falls under 5% with conservative inputs, renegotiate price or pick a different micro-location.
Frequently Asked Questions
Many well-managed condos land in a mid-single-digit to high-single-digit net range on all-in capital, depending on area, fees, and seasonality, but you must model your specific unit, not an island-wide average.
Use a conservative annual appreciation assumption and a clear exit price net of selling costs. Combine with cumulative net cash flows over the same horizon.
Model both. Operating cash flows are often baht-denominated; your net worth may be in USD or EUR, FX can materially change realized outcomes.
Condos in strong towers often offer simpler liquidity; villas can offer higher nightly rates but higher costs and more operational complexity. The better choice is the one that matches your capital, use plan, and exit path.
We connect realistic rental comps, fee stacks, and zone context, without charging buyer commission, so you can align price with expected net and total return.
Buyer scenarios: three ways the same ROI model is used
Scenario B: lifestyle owner blocks 4-8 high-season weeks and reprices ADR.
Scenario C: exit-focused buyer confirms resale comps and foreign quota before reservation.
