Property Analysis Tools UK: ROI vs Yield Calculators
ROI or yield? Cash flow or capital growth? Understanding which metrics matter for your investment strategy is crucial. This comprehensive guide breaks down every property analysis tool, metric, and calculator you need to make data-driven investment decisions in the UK market.
ROI vs Rental Yield: What's the Difference?
Return on Investment (ROI)
ROI measures your total profit as a percentage of your invested capital. It includes rental income, capital appreciation, and all costs.
ROI = (Total Profit ÷ Investment) × 100
Example: £40k profit ÷ £50k invested = 80% ROI
Rental Yield
Yield measures annual rental income as a percentage of property value. It's specific to rental income only.
Yield = (Annual Rent ÷ Price) × 100
Example: £9,600 rent ÷ £120k price = 8% yield
Essential Property Analysis Metrics
1. Cash Flow
Monthly rental income minus ALL expenses (mortgage, maintenance, management, insurance). Positive cash flow means the property pays for itself.
Cash Flow = Rent - (Mortgage + Expenses)
2. Cash-on-Cash Return
Annual cash flow as a percentage of actual cash invested. Critical for BRRR investors who refinance.
CoC = (Annual Cash Flow ÷ Cash Invested) × 100
3. Capital Growth Rate
Annual property value appreciation. UK average is 3-5% historically, but varies by location.
Growth = ((New Value - Old Value) ÷ Old Value) × 100
4. Net Operating Income (NOI)
Total rental income minus operating expenses (before mortgage payments). Used by commercial investors.
