What is the Core Investments Total Return Calculator?

An institutional-grade educational tool that models rental income, capital appreciation, payment-plan leverage, IRR, assignment profits, and exit scenarios for Phuket resort property investments. It runs entirely in your browser using assumptions you select.

Why does the calculator separate ROI on asset from ROI on capital deployed?

Because they are not the same number. Off-plan and pre-completion investors typically only pay a portion of the purchase price before exit; their return should be measured against capital they actually deployed, not against the full asset value.

What is an assignment before completion?

Assigning the purchase contract to another buyer before paying the final completion balance. The assignee assumes the remaining payment obligation. This allows sophisticated investors to realise capital appreciation on leverage without ever taking ownership of the asset.

How are scenarios calculated?

Three scenarios, Downside, Expected, Upside, re-run the engine with different yield, rental growth, and capital appreciation assumptions. Professional investors think in probability ranges, not single forecasts.

Are the projected returns guaranteed?

No. The calculator is educational and illustrative. Actual outcomes depend on market conditions, occupancy, tourism demand, exchange rates, regulatory changes, construction delays, operator performance and many other variables.

Does the calculator account for currency risk?

Currency is selected for display purposes. Investors with home currencies other than THB should model adverse currency moves separately; the What Could Go Wrong section quantifies a representative downside FX impact.

Why is ownership structure included as an input?

Ownership structure materially affects resale liquidity, inheritance simplicity, international buyer demand and exit flexibility. It is one of the most under-appreciated drivers of long-term investment outcomes.

What is the difference between investment stage and completion year?

Investment stage describes development progress and risk at the time of purchase. Completion year describes when rental operations begin. They are related but not identical and produce different risk profiles.

Understanding the key metrics

ROI: Measures total profit relative to Total Acquisition Cost.
ROCD: Measures return relative to capital actually deployed. Useful when comparing payment plans.
IRR: Measures annualised investment performance while accounting for the timing of cash flows. Often regarded as the most important institutional return metric.
Total Wealth Created: Combines rental income, capital gains and profit into a single figure.

Payment Structure Score

Deposit Burden
Pre-Handover Capital Requirement
Completion Burden
Assignment Flexibility
Schedule Smoothness

Most relevant for investors seeking to sell before handover.

Investment Quality Score

Investor glossary

Five terms, plain English.

IRR: The annualised return that accounts for when each cash payment and inflow actually occurs.
Return on Capital Deployed: Profit measured against the cash you actually paid in, not the full purchase price.
Conservative Scenario: The same model re-run with a 30% haircut to upside, to test if the deal still works when you're wrong.
Assignment Exit: Selling your purchase contract to another buyer before the final completion payment is due.
Cash Required at Completion: The balance owing to the developer at handover, plus furniture, transfer, sinking fund and utility deposits.
