3. Desired Return or Cap Rate (e.g. 8%)
4. (Optional) Down Payment and Financing Details for deeper cash-on-cash metrics

Click “Calculate” to receive:

• Estimated Property Value
• Annual Gross & Net Income
• Cap Rate Percentage
• Monthly and Annual Cash Flow
• Cash-on-Cash Return (if financing included)

📐 Formulas You Need

1. Cap Rate Valuation

javaCopyEditProperty Value = Net Operating Income (NOI) ÷ Cap Rate 

Where:

• NOI = Annual Rental Income − Annual Operating Expenses
• Cap Rate expressed as a decimal (e.g. 8% = 0.08)

2. Gross Rent Multiplier (GRM)

iniCopyEditGRM = Property Price ÷ Annual Gross Income 

3. Cash Flow Calculation

javaCopyEditAnnual Cash Flow = NOI − Annual Debt Service Cash-on-Cash Return = Annual Cash Flow ÷ Total Cash Invested 

📊 Example Calculation

Let’s say:

• Monthly Rent: $2,500 ⇒ Annual = $30,000
• Expenses: $300/month ⇒ Annual = $3,600
• Desired Cap Rate: 7% (0.07)

NOI = 30,000 − 3,600 = $26,400
Property Value ≈ 26,400 ÷ 0.07 = $377,143

With financing:

• Down Payment: $75,000
• Annual Debt Service (mortgage P&I): $14,400

Cash Flow = 26,400 − 14,400 = $12,000
Cash-on-Cash = 12,000 ÷ 75,000 = 16%

💡 Why These Metrics Matter

1. Cap Rate – Reveals the return relative to investment cost
2. Cash Flow – Demonstrates real monthly/yearly profit
3. Cash-on-Cash Return – Shows true investor return after financing
4. GRM – Helps compare similar properties quickly

✅ Benefits of Using This Tool

• Makes informed investment choices
• Reveals unseen financial opportunities quickly
• Compares multiple properties at ease
• Helps negotiate price or rental terms
• Useful for constructing acquisition models and forecasts

🧠 Pro Tips to Improve Calculations

• Always calculate property taxes accurately
• Factor in maintenance reserves and vacancy rates into NOI

🔍 Real‑World Applications

• Evaluating single-family or multi-family homes
