Successful real estate investing isn't about gut feelings or lucky breaks - it's about understanding and tracking the right metrics. Whether you're analyzing your first investment property or managing a portfolio of dozens, these five key metrics will help you make smarter decisions and maximize your returns.

1. Cap Rate (Capitalization Rate)

The cap rate is perhaps the most widely used metric in real estate investing. It measures the potential return on an investment property based on the income it generates.

How to Calculate

Cap Rate = (Net Operating Income / Property Value) x 100

What It Tells You

  • Higher cap rate: Generally indicates higher potential returns but may also suggest higher risk
  • Lower cap rate: Often found in stable, desirable markets with lower risk
  • Typical range: 4-10% depending on market and property type

Pro Tip: Use cap rate to compare similar properties in the same market. Avoid comparing cap rates across different markets or property types.

2. Cash-on-Cash Return (CoC)

While cap rate ignores financing, cash-on-cash return accounts for how you actually pay for the property. It measures the annual return on the actual cash you invested.

How to Calculate

CoC Return = (Annual Pre-Tax Cash Flow / Total Cash Invested) x 100

Why It Matters

Cash-on-cash return shows the true power of leverage. A property with a 5% cap rate might deliver a 12% cash-on-cash return with proper financing. Most investors target a minimum 8-12% CoC return.

3. Net Operating Income (NOI)

NOI is the foundation for calculating most other metrics. It represents the income a property generates after operating expenses but before mortgage payments and taxes.

How to Calculate

NOI = Gross Rental Income - Operating Expenses

Operating Expenses Include:

  • Property taxes
  • Insurance
  • Maintenance and repairs
  • Property management fees
  • Utilities (if landlord-paid)
  • Vacancy allowance

Important: NOI does not include mortgage payments, capital expenditures, or income taxes.

4. Debt Service Coverage Ratio (DSCR)

DSCR measures whether a property generates enough income to cover its debt obligations. Lenders use this metric to assess risk, and investors use it to evaluate financial safety.

How to Calculate

DSCR = Net Operating Income / Annual Debt Service

Interpretation

  • DSCR > 1.25: Generally considered safe - the property generates 25% more income than needed for debt payments
  • DSCR = 1.0: Break-even - income exactly covers debt
  • DSCR < 1.0: Dangerous territory - you'll need to cover shortfalls from other sources

Most lenders require a minimum DSCR of 1.2-1.25 for investment properties.

5. Internal Rate of Return (IRR)

IRR is the most comprehensive return metric because it accounts for all cash flows over the entire investment period, including the eventual sale.

What It Measures

IRR calculates the annualized return of an investment considering:

  • Initial investment
  • Ongoing cash flows (positive and negative)
  • Final sale proceeds
  • Time value of money

Target IRR

  • Conservative investors: 10-15%
  • Moderate risk tolerance: 15-20%
  • Value-add or development: 20%+

Putting It All Together

No single metric tells the complete story. Smart investors use all five metrics together to evaluate opportunities:

Metric Best For Typical Target
Cap Rate Quick property comparison 5-8%
Cash-on-Cash Evaluating leverage impact 8-12%
NOI Understanding cash flow Varies
DSCR Assessing safety margin >1.25
IRR Total return projection 15-20%
