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.

Calculator Guide

Before You Begin

Investment Modelling Inputs

RUN THE NUMBERS.

Adjust the figures below to explore different income, growth and return scenarios. Default values are based on current Phuket resort market data.

Assumption review

Appreciation acceleration of 3.00% compounds each year. In long holding periods this can produce implausible terminal values.

Educational guardrail only, calculations continue using your selected values.

Choose Ownership Structure

Choose Your Reporting Currency

Choose Your Payment Plan

Most efficient assignment structure. Only 45% capital deployed before completion.

Purchase date

Choose Completion Year

Choose Completion Month

Later completion generally means more construction risk, longer wait for income, and a greater appreciation runway before handover. Investment stage is derived automatically from the completion year.

Investment thesis

Selecting a market or thesis populates the four assumptions below. Any manual change switches both selectors to Custom.

Net rental yield

Rental growth p.a.

Capital appreciation p.a.

Institutional Method

How institutional investors actually evaluate property.

Most retail investors evaluate a property by looking at headline yield and a brochure appreciation figure. Institutional capital does the opposite. It treats every acquisition as a probability-weighted cash-flow problem, stress-tested against a defined risk budget and benchmarked against a holding-period return. The Core Investments Total Return Calculator™ is built around the same seven disciplines.

1. Cash flow

Cash flow is the net rental income the asset produces after operating costs, management fees, vacancy, taxes and reserves. Gross yield flatters every deck; net yield decides whether the asset funds itself. Underwrite operating expenses bottom-up, not as a percentage of revenue, and always model a vacancy assumption higher than the operator's marketing claim.

2. Capital growth

Capital growth is the change in asset value over the holding period. Disciplined investors separate market appreciation (driven by location, infrastructure, demand) from asset-specific appreciation (driven by product, brand, scarcity). In Thai resort markets, Phuket and Pattaya have historically delivered 6-10% annual capital growth on institutional-grade product, but the dispersion across submarkets is wide. Average growth is not a forecast for any specific asset.

3. IRR (Internal Rate of Return)

IRR is the discount rate that sets the net present value of every cash flow to zero. It answers a single question: what annualised return did this capital earn, accounting for when each dollar went in and came out? IRR rewards earlier cash returns and penalises late exits. For pre-completion investors, IRR on deployed capital is the only honest metric, because total purchase price was never funded.

4. Risk

Risk is not a vibe. Institutional risk frameworks isolate execution risk (developer, completion, construction), market risk (tourism, oversupply, regulation), operating risk (occupancy, ADR, operator solvency), and liquidity risk (exit window, buyer pool, currency). The calculator's downside scenario is a quantified expression of these risks, not a sentiment.

5. Holding periods

Returns are time-dependent. A 50% capital gain over three years and over ten years are different investments. Define the intended hold before underwriting, because exit assumptions (transaction costs, market liquidity, buyer profile) change with horizon. Most institutional Thai resort mandates run on a 5-10 year hold; assignment strategies run on an 18-36 month construction window.

6. Sensitivity analysis

Sensitivity analysis is the institutional equivalent of "what if I'm wrong?". It re-runs the model with each variable shifted independently to expose which assumption actually drives the outcome. A deal that breaks the moment occupancy falls five points is a fragile deal. A deal that survives a 20% currency move and a 200bp rate shift is a resilient deal. The Conservative / Base / Optimistic toggle is the surface of a multi-variable sensitivity engine running underneath.

7. Investment Intelligence Score™

The Investment Intelligence Score™ collapses the six disciplines above into a single 0-100 institutional verdict, weighted by investor profile (capital growth, rental income, retirement, diversification, short-term flip). It is not a recommendation; it is a research signal designed to surface the weakest dimension of an opportunity so that investor capital is allocated to where the evidence is strongest.

The calculator above runs every one of these calculations live on assumptions the investor controls. No saved data, no email gate, no upsell. Just the framework institutional capital uses, made available to private investors.
