Capitalization rate, or cap rate, is one of the fundamental metrics in real estate investing. It measures a property's income potential relative to its price — completely independent of financing. This makes it a clean, standardized way to compare properties and markets, regardless of how they're financed.
Cap rate is defined as:
Cap Rate = Net Operating Income (NOI) / Property Value (or Purchase Price)
Net Operating Income is your annual rental income minus all operating expenses — property taxes, insurance, maintenance, management fees, and vacancy allowance — but before mortgage payments. Mortgage financing is intentionally excluded so that cap rate reflects the asset's performance independent of how it's funded.
You're analyzing a triplex in Calgary:
Cap rates vary enormously across Canadian markets, reflecting different levels of price appreciation expectations and demand. There's no universal "good" cap rate — it depends entirely on context:
Cap rates in Toronto and Vancouver commonly range from 3.0-4.5% for residential income properties. Investors accept these low yields because they expect significant appreciation over time. A 3.5% cap rate reflects a belief that asset value growth will provide the majority of returns.
Alberta markets typically offer cap rates of 4.5-6.5% on residential income properties. The higher yields reflect less aggressive appreciation expectations and more reliance on current income. Cash flow is more accessible here.
Smaller Maritime markets can offer 5-8% cap rates on well-maintained income properties. Higher yields reflect historically lower price appreciation, though this has been changing with migration trends.
Commercial cap rates in Canada span a wide range: industrial properties may trade at 4-6%, well-located retail at 5-7%, suburban office at 6-8% or more depending on occupancy and quality.
Cap rate and cash-on-cash return are related but different metrics. Understanding both is important:
Measures property income relative to total property value. Independent of financing. Used to compare properties and markets objectively.
Annual pre-tax cash flow divided by total cash invested (down payment plus closing costs). This is financing-dependent. A 5.5% cap rate property with 80% financing might produce a 7-9% cash-on-cash return if financed efficiently, or negative cash-on-cash if mortgage rates are high.
Cash-on-cash tells you what you're actually getting on the cash you put in. Cap rate tells you what the building earns as an asset.
Cap rates can also be inverted to estimate property value from income:
Property Value = NOI / Market Cap Rate
If comparable properties in a market trade at 5% cap rates and a building generates $50,000 in NOI, its indicated value is $50,000 / 0.05 = $1,000,000.
This is how commercial properties are typically valued and how investors assess whether an asking price is justified. If a seller is asking $1.2M for a building generating $50,000 NOI, that's a 4.2% cap rate — you need to decide whether the location, quality, and appreciation potential justify paying for that compressed cap rate.
Low cap rates (like Toronto's 3-4%) mean you're paying a high multiple for each dollar of current income. This is only rational if you believe future income growth or price appreciation will justify the premium. High cap rates mean more current income relative to price — lower reliance on speculation about future appreciation.
The appropriate cap rate target depends on your investment goals: if you need current income to live on, higher cap rates matter. If you're building long-term wealth and can fund negative cash flow from employment income, lower cap rates in high-appreciation markets may be acceptable.
Cap rate is a useful screening tool but has limitations:
Use cap rate as one of several analytical tools, not the only one. Combined with cash flow analysis, market analysis, and due diligence on the specific property and its tenants, cap rate gives you a solid foundation for investment decisions.
