If you want to understand where Calgary's real estate market is headed, months of inventory (MOI) is arguably the single most powerful metric to watch. It tells you how long it would take to sell every active listing at the current pace of sales — and in a city as dynamic as Calgary, that number has swung dramatically over the past several years. As of mid-2026, the MOI data is telling a nuanced story: one of gradual rebalancing after years of seller-market intensity, with important variations across property types and price bands. Let's break down the numbers.
What Is Months of Inventory — and Why Does It Matter?
Months of inventory is calculated by dividing the total number of active listings at the end of a given month by the number of sales recorded that month. The result is a ratio that defines market conditions:
- Under 2 months: Strong seller's market — upward price pressure, multiple offers common
- 2–4 months: Balanced-to-seller's market — prices generally stable to rising
- 4–6 months: Balanced market — neither buyers nor sellers hold a strong edge
- Over 6 months: Buyer's market — downward price pressure, longer days on market
For context, Calgary's MOI has oscillated across all of these bands within the last decade, making it a rich dataset to analyse.
The Historical Baseline: 2018–2021
Between 2018 and 2020, Calgary sat firmly in buyer's market territory, with MOI consistently ranging between 5 and 8 months across the broader residential market. The oil price downturn, interprovincial out-migration, and an oversupply of condo units all weighed on absorption rates. Detached homes in the $500,000–$700,000 range were particularly soft, sometimes posting MOI figures above 7 months.
The pandemic-era demand surge of 2021 flipped the script. By Q4 2021, citywide MOI had compressed to approximately 1.5–2.0 months — a level that shocked even seasoned Calgary observers accustomed to more measured market cycles.
The 2022–2024 Seller's Market Squeeze
Calgary defied the national cooling trend of 2022–2023, which saw markets like Toronto and Vancouver shed significant value as interest rates climbed. While MOI in those cities spiked above 4 months, Calgary's remained stubbornly low — hovering between 1.8 and 2.9 months through most of 2022 and 2023. This was largely attributable to sustained interprovincial migration from British Columbia and Ontario, robust employment growth in both the energy and technology sectors, and a comparatively affordable entry price point that continued to attract first-time buyers and investors alike.
By 2024, MOI began a gradual ascent, reaching approximately 2.5–3.2 months on a citywide basis by year-end — still a seller's market, but with early signs of normalisation beginning to emerge in higher price bands.
Where We Stand in Mid-2026
As of Q2 2026, Calgary's overall residential MOI has settled into the 3.0–4.0 month range — a meaningful shift from the sub-2.0 readings of the post-pandemic peak. Breaking this down by property type reveals important divergences:
- Detached homes: Approximately 3.2–3.8 months citywide, with inner-city communities still tighter at roughly 2.5 months. The $700,000–$900,000 segment is showing the most rebalancing.
- Semi-detached and row homes: Still among the tightest segments at 2.0–2.8 months, driven by first-time buyer and downsizer demand. Inventory additions in this category have lagged demand for several consecutive years.
- Apartment condominiums: The loosest segment at 4.2–5.0 months, reflecting a significant pipeline of new construction completions entering the market simultaneously. The $300,000–$450,000 condo tier is showing buyer-friendly conditions for the first time since 2020.
Geographic Variations Within Calgary
MOI is not uniform across the city. Communities in the northwest and southeast — particularly newer suburban nodes — are experiencing MOI figures closer to 4.5–5.5 months as new-build competition weighs on resale absorption. Conversely, established inner-city communities such as Altadore, Killarney, and Mount Pleasant continue to post MOI readings under 3 months, sustained by land scarcity and lifestyle demand.
What the Trend Line Suggests
The directional trend through 2025 and into 2026 has been a steady, measured increase in MOI — approximately 0.2–0.3 months of additional supply per quarter on a rolling 12-month basis. This is not a crash trajectory; it is a normalisation. Several factors are worth monitoring closely:
- New listing growth: Active listings in June 2026 were tracking well above five-year seasonal averages, suggesting sellers are increasingly motivated to test the market.
- Sales velocity: While still healthy in absolute terms, year-over-year sales volumes have moderated, reducing the denominator in the MOI equation and pushing the ratio higher.
- Interest rate sensitivity: Any Bank of Canada rate adjustments in H2 2026 will have an outsized impact on affordability-constrained segments — particularly the condo market.
The Analytical Takeaway
Calgary's MOI data in mid-2026 presents a market in transition. The days of sub-2-month inventory and routine bidding wars are largely behind us — at least for now — outside of specific high-demand niches. Buyers have more time, more choice, and more negotiating leverage than at any point since 2020. For investors, the condo segment deserves careful scrutiny: rising inventory and a substantial new-supply pipeline could create genuine buying opportunities, but also pricing headwinds in the near term. For detached home buyers, the data still favours relatively swift decision-making, particularly in established inner-city corridors where inventory remains constrained. Watching MOI on a month-to-month basis remains the most reliable way to stay ahead of price trajectory shifts in this market.
