How to Calculate ROI on Phuket Property: Formulas, Benchmarks, and Real Numbers for 2026
A condo in Phuket priced at 8 million baht generates 35,000 baht per month in rent. Is that a strong investment or a mediocre one? Without a precise ROI calculation, the answer is impossible. Most buyers confuse gross yield with net yield, overlook depreciation and taxes, and end up surprised when their real return is half of what the brochure promised.
This guide breaks down exactly how to calculate genuine investment returns on Phuket property in 2026 - with concrete formulas, district benchmarks, and a full cost checklist that developers tend to leave out of their presentations.
Quick Answer
- Gross yield on Phuket property in 2026 ranges from 5% to 8% per year depending on district and property type
- Net yield after all expenses typically lands between 3.5% and 6%
- The gap between gross and net yield is 1.5 to 3 percentage points - sometimes wider, depending on your management structure
- Quality condominiums in high season achieve 85-95% occupancy; in low season that drops to 40-60%
- Exit liquidity: reselling a property typically takes 6 to 18 months, with transfer fees and taxes consuming 3% to 6.3% of the sale price
- A complete ROI formula must include not just rental income but also capital appreciation, which runs 5-10% per year in high-demand Phuket locations
Scenarios and Options
Scenario 1: Studio Condo in Bang Tao - 5 Million Baht
A 30 sqm studio within walking distance of the beach. Average rental rate: 25,000 baht/month in high season, 15,000 baht/month in low season. At an annual average occupancy of 70% (roughly 255 days), gross rental income comes to approximately 510,000 baht per year.
Gross yield: 510,000 / 5,000,000 = 10.2%
That number looks impressive - but it is misleading. Now subtract the real costs:
- Common area fee: 18,000 baht/year (around 50 baht/sqm/month)
- Sinking fund contribution: 15,000 baht one-time, amortized over 10 years = 1,500 baht/year
- Property management company: 20-30% of income = 102,000-153,000 baht/year
- Personal income tax (PIT): 5-15% of income depending on structure
- Insurance: 5,000-8,000 baht/year
- Minor repairs and furniture replacement: 30,000-50,000 baht/year
- Internet, electricity during vacancy, cleaning: 20,000-30,000 baht/year
Total annual expenses: approximately 200,000-280,000 baht.
Net yield: (510,000 - 240,000) / 5,000,000 = 5.4%
The gap between gross and net is nearly 5 percentage points. Relying on gross yield alone gives you a deeply distorted picture.
Scenario 2: Pool Villa in Rawai - 15 Million Baht
A 3-bedroom villa of 200 sqm with a private pool. High-season daily rate: 6,000-10,000 baht; low-season rate: 3,000-4,500 baht. At 55% occupancy (200 days) and an average daily rate of 5,500 baht, gross annual income reaches 1,100,000 baht.
Gross yield: 1,100,000 / 15,000,000 = 7.3%
Operating costs for a villa are substantially higher than for a condo:
- Pool maintenance: 60,000-90,000 baht/year
- Gardener: 48,000-72,000 baht/year
- Property management: 25-35% of income = 275,000-385,000 baht/year
- Grounds maintenance and security: 30,000-60,000 baht/year
- Taxes and insurance: 40,000-80,000 baht/year
- Repairs and furniture depreciation: 80,000-120,000 baht/year
Total annual expenses: approximately 550,000-800,000 baht.
Net yield: (1,100,000 - 670,000) / 15,000,000 = 2.9%
The villa generates more absolute income, but the net yield is lower. The trade-off is capital appreciation potential - quality villas in emerging Phuket districts have been appreciating at 8-12% per year according to current market data.
Scenario 3: Laguna Condo - 12 Million Baht
A 2-bedroom unit of 65 sqm in a premium development. Rental rate: 50,000-70,000 baht/month in high season. Occupancy: 65%. Estimated annual income: approximately 850,000 baht.
Gross yield: 850,000 / 12,000,000 = 7.1%
Net yield after management fees (25%), common fees, taxes, and repairs: approximately 4.5-5.2%.

The Full ROI Formula
Many investors calculate ROI purely as rental yield. That is an incomplete picture. Full ROI has two components:
ROI = Net Rental Yield + Capital Appreciation
The complete annual ROI formula:
ROI (%) = [(Annual Rental Income - All Expenses) + (Annual Capital Gain)] / Total Purchase Cost x 100
Where total purchase cost includes:
- Property price
- Transfer fee (typically 2%, often split between buyer and seller by negotiation)
- Legal fees: 30,000-80,000 baht
- Furnishings if not included: 200,000-500,000 baht for a condo
- Sinking fund: 500-800 baht/sqm
Main Risks and Mistakes
Mistake 1: Trusting the gross yield in a developer's brochure. Developers frequently advertise guaranteed returns of 7-10% for 3-5 years. In many cases, this guarantee is already baked into the purchase price as a 15-20% markup. Once the guarantee period ends, real-world yields often fall by 2-3 percentage points.
Mistake 2: Ignoring seasonality. Phuket is a seasonal market. High season runs from November through April; low season runs May through October. Rental rates can differ by 40-60% between seasons. Projecting full-year income at high-season rates will lead to consistent disappointment.
Mistake 3: Underestimating management fees. Property management companies charge 20-35% of rental income. Some add hidden charges for marketing, cleaning, and check-in/check-out services. Always request a complete fee schedule in writing before signing.
Mistake 4: Forgetting exit taxes. When reselling in Thailand, expect: transfer fee (2%), specific business tax (3.3% if held less than 5 years) or stamp duty (0.5% if held more than 5 years), plus withholding tax. Combined, exit costs range from 3% to 6.3% of the registered sale price.
Mistake 5: Not verifying actual occupancy in the target district. Occupancy varies considerably by location. Patong and Kata deliver high volume but lower nightly rates. Bang Tao and Layan command higher rates but require strong marketing and a well-managed property.
Risk - over-reliance on a single operator. If your sole management company performs poorly, income drops with no alternative. Always research whether alternative management options exist before committing to a purchase.
FAQ
What is the average property yield in Phuket in 2026? Net yield on quality properties currently sits at 3.5-6% per year. Adding capital appreciation, total annual ROI can reach 10-15% for well-located assets.
What is the difference between gross yield and net yield? Gross yield divides annual rental income by property price. Net yield subtracts all expenses - management fees, taxes, repairs, common fees, and insurance - before dividing. The gap is typically 1.5 to 5 percentage points.
How much do property managers charge in Phuket? Standard rates run 20-30% of rental income. Premium operators may charge up to 35% but often deliver higher occupancy and better average nightly rates.
Which Phuket district offers the best ROI? Bang Tao and Laguna offer the strongest balance of rental rates and occupancy. Cherngtalay and Nai Thon are emerging areas with solid capital appreciation potential, though rental infrastructure is still developing.
Are developer rental guarantees reliable? Rental guarantees are primarily a marketing tool. They typically offer 5-7% for 3-5 years and are usually priced into the unit cost. After the program ends, actual market yields often come in lower.
Should ROI be calculated in baht or in a home currency? Income is generated in Thai baht. Currency fluctuations between the baht and other currencies can shift effective returns by 5-15% per year. It is best practice to calculate and benchmark ROI in baht to isolate the property's actual performance.
What is the minimum budget for a cash-flow positive investment in Phuket? The entry point for reliable net positive income starts at roughly 3.5-4 million baht (approximately 100,000 USD) for a studio unit in a quality development with professional management in place.
Does buying off-plan improve ROI? Yes - off-plan prices are typically 15-25% lower than completed market values. That discount immediately improves your ROI when calculated against the asset's post-completion market value.
How quickly can you resell a Phuket property? Liquid condos in prime locations typically sell within 6-12 months. Villas average 12-18 months. Non-standard properties in remote areas can remain on the market for 2-3 years.
The core principle is straightforward: always calculate ROI using net yield plus capital appreciation - never gross yield alone. Ask your management company for verified occupancy data covering the last 12 months. Review every line item of the cost schedule before signing. And remember: a reliable projection is always more conservative than a sales presentation.
