How to Calculate Cap Rate Like BiggerPockets (Complete Guide)
The capitalization rate (cap rate) is one of the most important metrics in real estate investing. Used by professionals on platforms like BiggerPockets, the cap rate helps investors quickly compare the potential return on different investment properties without considering financing. This comprehensive guide will teach you exactly how to calculate cap rate the BiggerPockets way.
What Is Cap Rate?
The capitalization rate (cap rate) is the ratio between a property’s net operating income (NOI) and its current market value. Expressed as a percentage, it represents the potential annual return on investment if the property were purchased with cash (no mortgage).
The formula is:
Cap Rate = (Net Operating Income / Current Market Value) × 100
Why Cap Rate Matters in Real Estate Investing
Cap rate serves several critical functions for real estate investors:
- Quick Comparison Tool: Allows investors to compare different properties regardless of size or price
- Risk Assessment: Higher cap rates generally indicate higher risk (and potentially higher reward)
- Market Analysis: Helps identify whether a market is overvalued or undervalued
- Financing-Neutral: Evaluates the property’s performance independent of mortgage payments
- Exit Strategy Planning: Helps determine potential resale value based on income
How BiggerPockets Calculates Cap Rate
BiggerPockets uses a standardized approach to cap rate calculation that accounts for all operating expenses. Here’s their step-by-step methodology:
- Determine Gross Potential Income: The total income if the property were 100% occupied with no vacancies
- Subtract Vacancy Loss: Typically 5-10% of gross income to account for vacant periods
- Add Other Income: Include income from laundry, parking, vending machines, etc.
- Calculate Effective Gross Income (EGI): Gross income minus vacancy plus other income
- Subtract Operating Expenses: Includes property taxes, insurance, repairs, management fees, utilities, etc.
- Arrive at Net Operating Income (NOI): EGI minus all operating expenses
- Divide NOI by Property Value: This gives you the cap rate as a decimal
- Convert to Percentage: Multiply by 100 to get the cap rate percentage
Typical Cap Rate Ranges by Property Type
Cap rates vary significantly by property type, location, and market conditions. Here’s a general breakdown of what to expect:
| Property Type | Low-Risk Market Cap Rate | Average Market Cap Rate | High-Risk Market Cap Rate |
|---|---|---|---|
| Single-Family Homes | 3% – 5% | 5% – 7% | 8% – 10% |
| Multi-Family (2-4 units) | 4% – 6% | 6% – 8% | 9% – 12% |
| Small Apartment Buildings (5-50 units) | 5% – 7% | 7% – 9% | 10% – 14% |
| Large Apartment Complexes (50+ units) | 4% – 6% | 6% – 8% | 9% – 12% |
| Commercial (Retail) | 5% – 7% | 7% – 9% | 10% – 15% |
| Commercial (Office) | 4% – 6% | 6% – 8% | 9% – 13% |
| Industrial | 6% – 8% | 8% – 10% | 11% – 15% |
Common Mistakes When Calculating Cap Rate
Even experienced investors sometimes make these critical errors:
- Including Mortgage Payments: Cap rate should only consider the property’s income and operating expenses, not financing costs
- Using Asking Price Instead of Market Value: Always use the property’s actual market value, not just the listing price
- Underestimating Expenses: Many investors forget to account for all operating expenses like capital expenditures
- Ignoring Vacancy Rates: Assuming 100% occupancy will inflate your cap rate unrealistically
- Mixing Up Gross and Net Income: Always use net operating income, not gross income
- Not Adjusting for Market Conditions: Cap rates should be compared to local market averages
How to Improve Your Property’s Cap Rate
If you want to increase your property’s cap rate (and thus its value), focus on these strategies:
- Increase Rental Income: Raise rents to market rates or add income streams like laundry or parking
- Reduce Vacancy: Improve tenant screening and property marketing to minimize vacant periods
- Cut Operating Expenses: Negotiate better rates on insurance, find more affordable contractors
- Add Value-Add Improvements: Renovations that allow for higher rents without proportionally increasing expenses
- Improve Property Management: More efficient management can reduce costs and improve tenant retention
- Refinance to Lower Property Taxes: In some areas, refinancing can trigger a reassessment that lowers taxes
Cap Rate vs. Cash on Cash Return
While both metrics evaluate real estate investments, they serve different purposes:
| Metric | Calculation | Considers Financing | Best For | Typical Range |
|---|---|---|---|---|
| Cap Rate | NOI / Property Value | No | Comparing properties regardless of financing | 4% – 12% |
| Cash on Cash Return | Annual Cash Flow / Total Cash Invested | Yes | Evaluating return on actual cash invested | 6% – 20%+ |
Use cap rate when you want to compare properties regardless of how you finance them. Use cash on cash return when you want to evaluate the return on your actual invested capital considering your specific financing terms.
Cap Rate by Market: What’s Considered Good?
What constitutes a “good” cap rate varies dramatically by location. Here’s a breakdown of typical cap rates in different U.S. markets:
- Primary Markets (NYC, LA, SF): 3% – 5% (low risk, stable appreciation)
- Secondary Markets (Austin, Denver, Atlanta): 5% – 7% (balanced risk/reward)
- Tertiary Markets (Smaller cities, rural areas): 8% – 12%+ (higher risk, higher potential returns)
- Distressed Markets: 12% – 18%+ (very high risk, potential for high rewards)
Remember that higher cap rates typically indicate higher risk. A 12% cap rate property in a declining rust-belt city may be riskier than a 5% cap rate property in a growing sun-belt market.
Advanced Cap Rate Concepts
Once you’ve mastered basic cap rate calculations, consider these advanced concepts:
- Terminal Cap Rate: The cap rate used to estimate a property’s value at the end of the holding period
- Going-In Cap Rate: The cap rate at the time of purchase (what you’re paying)
- Going-Out Cap Rate: The cap rate at the time of sale (what the market will pay)
- Band of Investment: A method that incorporates both equity and debt components into cap rate calculation
- Cap Rate Compression/Expansion: How cap rates change over time due to market conditions
Cap Rate Calculator Limitations
While cap rate is an essential metric, it has several important limitations:
- Ignores Financing: Doesn’t account for mortgage payments or leverage benefits
- No Time Value of Money: Treats all future income as equal to current income
- Static Metric: Doesn’t account for potential rent growth or expense increases
- No Tax Considerations: Doesn’t factor in depreciation or tax benefits
- Market Dependent: A “good” cap rate in one market may be terrible in another
For these reasons, savvy investors use cap rate in conjunction with other metrics like cash on cash return, internal rate of return (IRR), and net present value (NPV).
Final Thoughts on Using Cap Rate
The capitalization rate remains one of the most fundamental and widely used metrics in real estate investing for good reason. When calculated correctly (using the BiggerPockets methodology shown in our calculator above), it provides a quick, financing-independent way to compare investment properties.
Remember these key takeaways:
- Always use net operating income (NOI), not gross income
- Be conservative with your expense estimates
- Compare cap rates to local market averages
- Higher cap rates typically mean higher risk
- Use cap rate as one tool among many in your investment analysis
- Re-evaluate cap rates periodically as market conditions change
By mastering cap rate calculations and understanding their implications, you’ll be well-equipped to make smarter real estate investment decisions—just like the pros on BiggerPockets.
