What is Cap Rate?
📊 Definition
The Capitalization Rate (Cap Rate) represents the fundamental relationship between a property's income-generating capacity and its market value. It provides a standardized metric to compare properties across different price points, locations, and market conditions.
Cap Rate Formula
Cap Rate = NOI ÷ Property Value × 100
Net Operating Income ÷ Current Market Value × 100
What It Measures:
The property's income-generating potential as a percentage of its market value, representing the annual return an all-cash investor would receive.
Key Insight:
Unlike cash-on-cash return, cap rate measures the property's inherent investment quality independent of financing terms.
Step-by-Step Cap Rate Calculation
Calculate Gross Annual Income
Monthly Rent × 12 + Other Income Sources
Example: $1,500/month rent = $18,000 + $600 pet fees = $18,600 gross annual income
Account for Vacancy Rate
Gross Income × (1 - Vacancy Rate %)
Example: $18,600 × (1 - 0.05) = $17,670 effective gross income (5% vacancy)
Calculate Operating Expenses
✅ Include:
- • Property taxes
- • Insurance
- • Property management
- • Maintenance & repairs
- • Utilities (if landlord-paid)
- • Legal/professional fees
❌ Exclude:
- • Mortgage payments
- • Depreciation
- • Capital improvements
- • Income taxes
- • Acquisition costs
Example: Property taxes $2,400 + Insurance $1,200 + Management $1,413 + Maintenance $1,500 + Other $787 = $7,300 total expenses
Calculate Net Operating Income (NOI)
Effective Gross Income - Operating Expenses = NOI
Example: $17,670 - $7,300 = $10,370 Net Operating Income
Calculate Final Cap Rate
Cap Rate = $10,370 ÷ $155,000 × 100 = 6.69%
Result: This property has a 6.69% cap rate, which is solid for most markets
