Gross Yield vs Net Yield: The Gap That Costs You 3–5% in Real Returns

An investor buys a Phuket condo for 8 million baht. The management company promises 7% annual returns. Twelve months later, the account shows 340,000 baht — not the expected 560,000. That is nearly 40% less than projected. Where did the money go? It disappeared into the gap between gross yield and net yield.

This gap is not an academic footnote. It determines whether your investment breaks even in 12 years or in 20. In Thailand, developers and management companies almost universally quote gross yield in their marketing materials. Understanding net yield is the only reliable defence against inflated expectations — and the single most important calculation any serious investor should make before signing.

Quick Answer

• Gross yield = annual rental income ÷ purchase price × 100%. No expenses are deducted.
• Net yield = (annual rental income − all operating costs) ÷ total purchase price × 100%.
• Typical gross yield for a Phuket condo in 2026: 5–8%. Typical net yield: 3–5%.
• The gap between gross and net in Phuket ranges from 2 to 4 percentage points, depending on property type and location.
• Management companies typically retain 20–30% of rental income as their commission — the single largest cost line.
• Withholding tax on rental income in Thailand is 5–15% for individuals, depending on ownership structure.
• A net yield above 4% in 2026 is considered strong for Thai resort property.

Scenarios and Options

Scenario 1 — Phuket Condo in a Guaranteed Rental Pool

A developer offers a guaranteed return of 6% gross for three years on a 5-million-baht studio. The headline figure looks compelling. But the arithmetic tells a different story.

Gross income: 300,000 baht per year.

Deductions: management commission at 25% — 75,000 baht; common area maintenance (CAM fee) — 30,000 baht; insurance — 5,000 baht; tax — 15,000 baht; annual sinking fund contribution — 10,000 baht. Total costs: 135,000 baht.

Net income: 165,000 baht. Net yield: 3.3%.

The guaranteed 6% gross yield becomes a 3.3% net yield. The payback period extends from roughly 17 years to approximately 30 years — a material difference for any investment thesis.

Scenario 2 — Pool Villa in Rawai via Short-Term Rentals

A 15-million-baht villa with a private pool, operated through short-term rental platforms at 65% occupancy and an average nightly rate of 5,500 baht, generates approximately 1,300,000 baht per year in gross income. Gross yield: 8.7%.

Villa operating costs are substantially higher than condos: management commission at 30% — 390,000 baht; pool and garden maintenance — 120,000 baht; utilities partially covered by the owner in low season — 60,000 baht; land tax and insurance — 25,000 baht; furniture replacement and minor repairs — 80,000 baht; marketing and photography — 30,000 baht. Total costs: 705,000 baht.

Net income: 595,000 baht. Net yield: 3.97%.

The 8.7% gross figure compresses to just under 4% net. However, villas in sought-after Phuket locations carry a meaningful advantage: capital appreciation potential of 5–8% per year, which significantly improves total return on investment when combined with rental income.

Scenario 3 — Bangkok Condo on Long-Term Lease

A Sukhumvit apartment purchased for 6 million baht rents at 25,000 baht per month on an annual contract. Gross yield: 5%.

Long-term rentals carry lower operating costs: agency fee for tenant sourcing (amortised over 12 months) — 25,000 baht; CAM fee — 36,000 baht; tax — 12,000 baht; average vacancy of one month per year — 25,000 baht in lost income. Total costs: 98,000 baht.

Net income: 202,000 baht. Net yield: 3.37%.

Bangkok long-term rentals offer greater stability and lower management complexity, but net yields remain modest. Capital appreciation in established Sukhumvit corridors typically runs at 2–4% per year.

Main Risks and Mistakes

1. Accepting advertised gross yield figures without independent verification. Developers and management companies routinely quote gross yields of 7–10%. This is standard marketing practice — not necessarily misleading, but it requires your own recalculation before making any commitment.

2. Overlooking CAM fees and sinking fund contributions. In Phuket, CAM fees for luxury condos can reach 80–100 baht per square metre per month. For a 35-square-metre studio, that amounts to 33,600–42,000 baht per year — enough to eliminate a significant portion of net income.

3. Ignoring furniture and appliance depreciation. A fully furnished condo requires replacement of key items every 3–5 years. Budget a minimum of 50,000–80,000 baht per year for properties in the 5–8 million baht range. This cost is almost never mentioned in developer projections.

4. Confusing yield with ROI. Yield measures current rental income relative to purchase price. ROI (return on investment) incorporates capital appreciation as well. A villa generating a net yield of 4% with 6% annual capital growth delivers a combined ROI of approximately 10% — materially stronger than a condo at 3.3% net yield with 3% capital growth.

5. Underestimating currency risk. International investors receiving income in Thai baht are exposed to exchange rate movements. A 5% depreciation of the baht against the dollar or euro reduces real returns accordingly. Benchmark all projections consistently in a single currency.

6. Failing to account for tax obligations before purchase. Rental income in Thailand is taxable. The ownership structure — individual name versus a Thai company — directly affects the applicable rate. A consultation with a qualified tax lawyer prior to purchase can save tens of thousands of baht annually over the holding period.

5-Minute Net Yield Checklist:

1. Start with the advertised gross annual rental income.
2. Deduct the management commission (20–30%).
3. Deduct CAM fees and sinking fund contributions (request exact figures from the developer).
4. Deduct 5–10% for vacancy and unforeseen expenses.
5. Deduct tax obligations (5–15% of net income).
6. Divide the result by the total acquisition cost, including transfer fees and legal expenses.

If the resulting figure exceeds 4% net, the property has strong investment fundamentals worth pursuing further.

FAQ

What net yield is considered strong in Phuket in 2026? A net yield of 4–5% is an excellent result for resort property. Combined with capital appreciation of 5–8% per year, this produces a total annual return of 9–13% — competitive with many alternative asset classes.

Why do management companies always quote gross yield? 7% sells better than 4%. Gross yield figures are a standard marketing tool across global real estate markets, not unique to Thailand. Your responsibility as an investor is to convert those figures into net yield before drawing any conclusions.

Which costs are most commonly forgotten when calculating net yield? Three categories are consistently underestimated: furniture and appliance depreciation, vacancy periods between tenants (even 2–3 weeks per year is meaningful at scale), and the cleaning and minor repair costs generated by each guest under short-term rental models.

How does net yield differ between leasehold and freehold structures? Leasehold properties — typically structured as 30-year land leases — are priced 15–25% lower than equivalent freeholds, which appears to inflate yield on paper. However, when the cost of lease renewal and the finite ownership horizon are factored in, the effective return may be lower than a freehold alternative.

How does seasonality affect yield calculations? Significantly. Phuket's high season (November through April) accounts for 60–70% of annual rental income. Projecting yield by multiplying peak-season nightly rates by 365 produces a materially overstated figure. Always use annualised occupancy averages from multiple sources.

How does the management commission percentage affect net yield in practice? The difference between a management company charging 20% versus 30% on a property generating 500,000 baht in gross income is 50,000 baht per year. Over a 10-year holding period, that compounds to 500,000 baht — equivalent to roughly one full percentage point of net yield annually.

Should net yield be the primary selection criterion? No. Net yield is one of five key investment parameters. Evaluate it alongside capital appreciation potential, resale liquidity, management company track record, and legal ownership structure. A property with a modest net yield but exceptional capital growth in a high-demand corridor may outperform a higher-yielding asset in a less liquid market.

How do I independently estimate net yield before purchasing? Request occupancy data from at least two or three local management companies for the target area. Obtain the exact CAM fee and sinking fund figures from the developer. Apply a realistic vacancy buffer and tax estimate. Divide adjusted net income by the full acquisition cost — not just the listed price.
