Revenue Simulator
See projected gross and net revenue from a villa's ADR, occupancy, and available nights.
Blended annual average, not a high-season peak rate.
Market median is ~66% across active Samui listings.
Reduce this if you plan to block out personal-use weeks.
Typical full-service Samui villa management runs 15–25% of revenue.
OTA commissions, housekeeping, utilities, maintenance — see Market Insights.
Illustrative only, based on the assumptions above. Excludes financing costs, taxes, and one-off capital expenses. See Market Insights for how we source these ranges.
ROI Calculator
Weigh purchase and setup cost against projected revenue to see gross yield and simple ROI.
Furniture, pool/landscaping finishing, listing photography, pre-opening costs.
Pull this from the Revenue Simulator for consistency.
Includes management fee, OTA commissions, staffing, maintenance, utilities.
Leave at 0 if buying without a loan.
"Simple payback" ignores the time value of money, appreciation, and resale — treat it as a rough sense-check, not a financial model. Always stress-test with a lower occupancy scenario before committing.
Self-Manage vs. Managed
A grounded comparison of running a villa yourself versus handing it to a professional operator.
Be honest — include guest messages, staff coordination, and pricing updates.
A villa of this complexity realistically needs ~15 hrs/week of attention to run well — you've indicated 6. That gap tends to show up as slower guest response and stale pricing.
- —~15 hrs/week of your time, ongoing
- —You handle pricing, guest messages, and staff directly
- —No management fee, but no backup when you're unavailable
- —~1.5 hrs/week — oversight only
- —Assumes ~8% revenue uplift from active pricing & distribution
- —฿475k/year management fee, faster guest response
In this scenario, self-managing nets ~฿73k more per year in raw income — the trade-off is ~15 hrs/week of ongoing work.
Talk through your scenarioThe 8% managed-revenue uplift and cost assumptions above are illustrative, based on typical differences we see between actively managed and self-managed villas — not a guarantee for any specific property.
Before you trust the numbers.
No. They model outcomes based on the assumptions you enter and the ranges we publish on the Market Insights page. Actual performance depends on the specific villa, its location, condition, pricing strategy, and management quality. Use them to stress-test assumptions, not as a promise of return.
We start from published 2026 Koh Samui market data (median occupancy and ADR across active listings, and separate luxury-segment figures) and our own operating portfolio, then let you adjust for your specific villa grade and location. See the full breakdown and sourcing notes on the Market Insights page.
Annual average, always. High season (Dec–Mar) can be 1.5–2x the shoulder-season rate, but a full-year projection needs to reflect the softer months too — particularly Sep/Oct, which is meaningfully slower. The simulator lets you enter a blended annual ADR and occupancy rather than a best-case number.

These tools give you a strong starting range. A consultation gets you a read on your specific villa — including the parts a calculator can't see.
