How It Works
Enter your available capital, property price, mortgage rate, and holding period. The calculator models two parallel scenarios: leveraged property versus S&P 500, comparing final wealth, annualised returns, and monthly cash flow across 5 scenarios.
Frequently Asked Questions
Why is leverage so powerful for property?
With a 20% deposit, you control 100% of the asset. If the property appreciates 5%, your return on the deposit is 25% (5% × 5x leverage). This amplification is the core advantage of property over direct stock investment.
What does the S&P 500 Historical scenario show?
It uses the actual S&P 500 CAGR from 2000 to 2024 (approximately 10.7% nominal), which includes the dot-com crash, the 2008 financial crisis, and the COVID recovery.
Does the calculator account for taxes?
The base model shows pre-tax returns. Tax treatment varies significantly by country and individual circumstances. Always consult a tax advisor.
When does the S&P 500 beat leveraged property?
In the Bear and Crisis scenarios, where property values fall and rental income may not cover mortgage payments, the S&P 500 often wins due to lower volatility and no leverage risk.
About This Calculator
This calculator helps real estate investors and prospective buyers understand the long-term financial implications of using leverage in real estate compared to investing directly in the stock market (e.g., S&P 500). By comparing potential returns, costs, and risks over a defined period, users can make more informed decisions about capital allocation and wealth accumulation strategies, especially in dynamic markets like Portugal.
How It Works
Define Investment Horizon
Specify the number of years you plan to hold both the real estate and stock market investments. This period is crucial for assessing compounding effects, long-term growth, and the impact of market cycles on both asset classes.
Real Estate Investment Details
Input the property purchase price, the percentage of down payment, the interest rate on the mortgage, and the estimated annual property appreciation. Also, consider annual operating expenses (e.g., IMI, condominium fees) and potential rental income, as these significantly impact the net return on your real estate investment.
Stock Market Investment Details
Enter the initial capital available for stock investment (typically equal to the real estate down payment) and the expected average annual return of the stock market index (e.g., S&P 500). Consider if you will make additional annual contributions, reflecting a consistent investment strategy.
Leverage Impact Assessment
The calculator will model how the borrowed capital (mortgage) amplifies returns in real estate, contrasting it with the unleveraged growth of the stock market investment. This step highlights the power of financial leverage, but also its associated risks, such as increased debt service and potential for magnified losses.
Compare Net Returns and Equity Growth
Review the projected final equity for both investment types, considering all costs, returns, and the impact of inflation. This comparison provides a clear picture of which strategy potentially yields higher wealth accumulation and better aligns with your financial goals over your chosen investment horizon.
Worked Example — Austin, Texas, United States
In Austin, Texas, United States, compare the same own capital against a $360,000 property and $270,000 financing at 6.4%.
- →Use the same time horizon and own-capital amount in every alternative.
- →Enter current local financing, operating-cost and return assumptions.
- →Compare risk, liquidity and after-tax consequences as well as the headline result.
The comparison is locally framed but remains sensitive to the assumptions you choose.
