ROI Calculator

Model rental income and long-term returns for Phuket and Koh Samui property using your own assumptions — occupancy, rental strategy, and management costs. All outputs are estimates, not guarantees.

Methodology

How This Model Works

Gross rental income is modelled as a zone-level nightly-rate baseline, adjusted by property type, multiplied by the nights implied by your occupancy and rental-strategy settings. Net figures deduct a management fee — 18% for condos and townhouses, 25% for villas in this model. Capital growth compounds a per-zone appreciation assumption over your holding period.

Every input is an assumption you control, and every output is an estimate. The zone baselines are editorial starting points, not observed market data, and no figure on this page is a forecast or a promise of return. Actual results move with seasonality, competition, licensing and operating costs.

One legal note for short-term strategies: renting stays of under 30 days requires a licence under the Hotel Act B.E. 2547, and unlicensed operation is a compliance risk that directly affects achievable occupancy. If you are comparing this model against a developer's "guaranteed return" programme, read our guide on guaranteed ROI vs actual rental yield first — the two are not the same thing.
