Property ROI combines two sources of return — capital appreciation (the rise in property value) and rental income (cash flow after expenses) — and expresses the combined profit as a percentage of the actual cash invested. The annualized version converts multi-year total returns into a CAGR-equivalent figure so property returns can be fairly compared against other investments like stocks or mutual funds.
This ROI formula measures cash-on-cash return — how hard your actual out-of-pocket money worked — not the full property value, since the loan portion is repaid separately through EMIs, not from your invested capital.
Generally, 8-12% annualized ROI is considered good for Indian residential real estate; above 15% is excellent, while below 5% suggests the investment is underperforming relative to alternatives like index funds.
