Understanding real estate investment metrics is like learning the language of successful investing. Whether you're a beginner trying to buy your first rental or a seasoned pro analyzing commercial properties, metrics help you cut through emotion and focus on the numbers that truly matter.
Let’s dive into the most important metrics every real estate investor should have in their toolkit—plus expert insights, relevant examples, and trustworthy resources to go deeper.
Capitalization Rate (Cap Rate)
Cap Rate measures the annual return on a property before financing. It’s used to compare investment opportunities.
Cap Rate = Net Operating Income / Property Purchase Price
Example:
Annual Gross Rent: $60,000
Operating Expenses: $15,000
Net Operating Income (NOI): $60,000 - $15,000 = $45,000
Purchase Price: $500,000
Cap Rate = 45,000 / 500,000 = 0.09 or 9%
If a property generates $60,000 in NOI and costs $15,000, the cap rate is 9%.
Expert Insight: According to Brandon Turner, former VP of Growth at BiggerPockets, “Cap rates are like a compass. They won’t give you every detail, but they help you get your bearings.”
Cash-on-Cash Return
Shows your annual return based on the cash you personally invested. Great for financed properties.
Cash-on-Cash Return = Annual Pre-Tax Cash Flow / Total Cash Invested
Example:
Down Payment: $80,000
Closing Costs & Repairs: $10,000
Total Invested: $90,000
Annual Cash Flow: $9,000
Cash-on-Cash Return = 9,000 / 90,000 = 0.10 or 10%
Gross Rent Multiplier (GRM)
A quick way to compare income-generating properties before diving into expenses.
GRM = Property Price / Gross Annual Rent
Example:
Price: $400,000
Monthly Rent: $3,500
Annual Rent: $42,000
GRM = 400,000 / 42,000 = 9.52
Internal Rate of Return (IRR)
IRR estimates your total average annual return, considering cash flow and appreciation over time.
How to calculate it:Use Excel’s built-in IRR function: =IRR({-Initial Investment, Year1CashFlow, Year2CashFlow, ..., FinalYearCashFlow})
Example:=IRR({-100000, 10000, 12000, 115000})This equals approximately 12.3%
Operating Expense Ratio (OER)
Shows how much of your income is eaten up by operating costs.
OER = Operating Expenses / Gross Operating Income
Example:
Operating Expenses: $15,000
Gross Income: $50,000
OER = 15,000 / 50,000 = 0.30 or 30%
Loan-to-Value Ratio (LTV)
Tells how much you're borrowing compared to the value of the property.
LTV = Loan Amount / Appraised Property Value
Example:
Loan: $320,000
Appraised Value: $400,000
LTV = 320,000 / 400,000 = 0.80 or 80%
Break-Even Ratio (BER)
Tells you how much income is needed to cover all expenses and debt. Helps you gauge risk.
BER = (Operating Expenses + Debt Payments) / Gross Operating Income
Example:
Expenses: $15,000
Annual Mortgage: $20,000
Gross Income: $50,000
BER = (15,000 + 20,000) / 50,000 = 0.70 or 70%
Summary Table
Metric | Formula | Ideal Range |
Cap Rate | NOI / Purchase Price | 5%–10% |
Cash-on-Cash Return | Cash Flow / Total Cash Invested | 8%–12%+ |
GRM | Price / Gross Annual Rent | Lower = Better |
IRR | Use Excel =IRR(...) | 12%–18%+ |
OER | Expenses / Gross Operating Income | Under 40% |
LTV | Loan / Property Value | Under 75–80% |
BER | (Expenses + Debt) / Gross Income | Under 85% |
Real estate is a numbers game. Emotions make headlines—but formulas make profits. These metrics won’t guarantee success, but they’ll keep you from flying blind.
As Grant Cardone says, “Never buy real estate emotionally. It’s always math, not mood.”
