What Is a Cap Rate?
The capitalization rate — almost always called the "cap rate" — is the most commonly cited metric in commercial real estate valuation. It measures the relationship between a property's net operating income and its market value. In plain language: cap rate tells you what percentage return you'd get on a property if you paid cash and collected the rent.
Or rearranged: Property Value = NOI ÷ Cap Rate
That second form is the one that matters most in practice. When a broker says "this strip plaza is trading at a 6% cap," they mean buyers are paying roughly 16.7 times the annual net operating income. When they say "ring road industrial is at 5%," they mean 20 times NOI.
The lower the cap rate, the higher the price relative to income. The higher the cap rate, the lower the price relative to income.
Quick Example
A warehouse in NE Calgary generates $180,000 net operating income per year.
Recent comparable sales suggest NE Calgary industrial trades at a 5.75% cap rate.
Estimated property value: $180,000 ÷ 0.0575 = $3,130,000
Net Operating Income — The Foundation
Cap rate is only as accurate as the NOI number going into it. NOI is defined as gross rental revenue minus operating expenses, before debt service (mortgage payments), income tax, and capital expenditures. Understanding what goes in and what stays out of NOI is critical.
Included in NOI calculation:
- Gross potential rental income (all leases at market rate)
- Minus vacancy allowance (typically 5–10% depending on asset type)
- Plus other income (parking, signage, antenna leases)
- Minus property taxes, insurance, property management fees, maintenance and repairs, utilities (landlord-paid), and administration
Not included in NOI:
- Mortgage payments (principal and interest)
- Income taxes
- Capital expenditures (roof replacement, HVAC, major repairs)
- Depreciation
Why Cap Rates Vary
Cap rates are not fixed numbers — they reflect market perception of risk, growth potential, and liquidity. Understanding why cap rates differ between assets helps you identify genuine value versus apparent yield.
Location
A grocery-anchored strip plaza in southwest Calgary trades at a tighter cap rate than an identical-looking plaza in a small Saskatchewan city — not because the building is better, but because Calgary has a larger, growing tenant pool, more buyers competing for the asset, and stronger long-term rent growth prospects. Risk is lower, so investors accept lower yield.
Tenant Quality and Lease Term
A single-tenant property occupied by a national covenant (Canadian Tire, Sobeys, Tim Hortons) on a 15-year net lease trades at a 4.50–5.50% cap rate because the income is effectively guaranteed. The same building occupied by a local operator on a month-to-month lease might trade at 7.00–8.00% because the risk of vacancy is real and imminent.
Asset Class
Different commercial asset classes carry structurally different risk profiles, which translate directly into cap rate expectations. Industrial has compressed dramatically over the past decade as logistics demand proved durable. Retail has bifurcated — essential-service retail is tight, discretionary retail remains challenged. Office carries the most uncertainty in 2026 given ongoing work-from-home trends.
Building Age and Capital Requirements
An older building needing roof, HVAC, or structural work will trade at a wider cap rate than a newer building in identical condition — even if current rents are identical. The market discounts for deferred capital, and sophisticated buyers will specifically quantify estimated capital expenditures over a hold period when determining their offer price.

Cap Rate vs Cash-on-Cash Return
One of the most common misunderstandings among newer commercial real estate investors is treating cap rate as their expected return. Cap rate is an unlevered measure — it assumes you paid all cash. Most investors use financing, and leverage significantly changes actual cash returns.
Leverage Effect Example
Property: NE Calgary industrial, $2,000,000 purchase price, $120,000 NOI
Cap rate: 6.0% (unlevered)
Financing: 65% LTV mortgage ($1,300,000 at 5.75% interest, 25-year am)
Annual debt service: ~$96,000
Cash flow after debt service: $120,000 − $96,000 = $24,000
Equity invested: $700,000 down payment
In this example, a 6% cap rate property delivers only a 3.4% cash-on-cash return after financing — because current interest rates (5.75%) are close to the cap rate. This is called "negative leverage" — borrowing actually reduces your yield. When interest rates were 2–3%, this same deal would have been powerfully positive leverage.
This dynamic explains why rising interest rates put downward pressure on commercial property values — buyers need cap rates to widen (prices to fall) to restore positive leverage and acceptable cash-on-cash returns.
Cap Rate Compression and Expansion
When cap rates "compress" — move lower — property values rise for the same income. When they "expand" — move higher — values fall. Understanding what drives compression and expansion helps you time acquisitions and dispositions more effectively.
Forces that compress cap rates (increase values):
- Falling interest rates (makes real estate more attractive relative to bonds)
- Increased investor demand for the asset class
- Improving market fundamentals (vacancy falling, rents rising)
- New institutional capital entering a market (as happened in Calgary 2021–2026)
Forces that expand cap rates (decrease values):
- Rising interest rates (reduces leverage appeal, increases required yield)
- Deteriorating market fundamentals (rising vacancy, falling rents)
- Reduced transaction liquidity
- Sector-specific demand destruction (e.g., retail during e-commerce disruption)
Practical Use of Cap Rates
When evaluating a commercial real estate purchase in Western Canada, cap rate should be one of several metrics — not the only one. Here is how Canada's Home Commercial brokers think about cap rate in the context of a full underwriting analysis:
- Verify the NOI. Sellers and listing agents have every incentive to present the most optimistic NOI. Review actual leases, historical operating statements, and get independent property tax and insurance quotes. A 10% NOI inflation translates directly to a 10% overvaluation at any given cap rate.
- Check market cap rates. Compare the asking cap rate against recent comparable sales. If a property is offered at a 5% cap rate in a market where comparables trade at 6%, you are either being asked to pay a premium or the seller sees something they haven't told you.
- Stress test for vacancy. What happens to your NOI — and your cap rate — if your anchor tenant vacates? A strip plaza at 5.5% with a single large tenant is a very different risk profile than one at 5.5% with eight small tenants.
- Account for capital expenditures. A property with $100,000 NOI and no near-term capital requirements is worth more than one with the same NOI but a $150,000 roof replacement needed in year two.
- Think about exit cap rate. If you buy at a 6% cap and sell in 5 years at a 7% cap (expansion), you've lost value even if rents grew. Your exit cap rate assumption drives your overall return.
