Shares vs Property Calculator

This calculator compares, in simple terms, how your money might grow if you invested it in shares versus using it as a deposit on a rental property, where borrowing can amplify your returns. This matters because shares and property grow differently: shares compound your own capital directly, while a property deposit lets you control a much larger asset through leverage, so a lower growth rate can still produce a bigger dollar gain, though the risks are higher too. You enter the capital you have to invest, the expected annual return on shares, the expected annual growth rate for property, the deposit percentage for the property, and your time frame in years. The calculator then projects both paths and returns your shares value, your property equity, and a verdict showing which produced the larger projected gain over your chosen period. Use it to see how leverage changes the numbers, and to compare return assumptions, deposit sizes or time frames side by side. This is a simplified growth comparison based only on asset values and starting capital; it does not account for rent, mortgage interest, rates, insurance, maintenance, tax or the effort and risk of owning property, all of which matter in real life. Treat the results as an indicative starting point for your own research, not financial advice, and weigh your risk tolerance and goals before deciding where to invest.

Highly simplified: shares grow your capital at the share return; property uses your capital as a deposit to buy a larger asset that grows at the property rate, with the gain magnified by leverage. It ignores rent, mortgage interest, tax, costs and risk, which are crucial in reality. Estimate only, not advice.
