📊 Key Formulas Used in Rental Property Analysis
Understanding the formulas behind the tool will help you better interpret the results.
1. Cash Flow (Monthly & Annual)
Formula:
Cash Flow = Total Rental Income – Total Monthly Expenses – Mortgage Payment
2. Net Operating Income (NOI)
Formula:
NOI = Annual Rental Income – Operating Expenses (excluding mortgage)
3. Capitalization Rate (Cap Rate)
Formula:
Cap Rate = (NOI / Property Price) × 100
4. Return on Investment (ROI)
Formula:
ROI = (Annual Cash Flow / Total Cash Invested) × 100
5. Gross Rental Yield
Formula:
Gross Rental Yield = (Annual Rental Income / Property Price) × 100
These formulas help investors assess both profitability and risk in their rental property ventures.
💡 Example Calculation
Let’s look at a sample analysis using the calculator:
- Monthly Rent: $2,000
- Expenses (Taxes, Insurance, etc.): $500
- Mortgage Payment: $1,000
- Purchase Price: $250,000
- Down Payment: $50,000
Step-by-Step:
- Monthly Cash Flow = $2,000 – $500 – $1,000 = $500
- Annual Cash Flow = $500 × 12 = $6,000
- NOI = ($2,000 × 12) – ($500 × 12) = $24,000 – $6,000 = $18,000
- Cap Rate = ($18,000 / $250,000) × 100 = 7.2%
- ROI = ($6,000 / $50,000) × 100 = 12%
From this, we can tell the investment is positive cash-flowing with a decent ROI.
