Proprobin - how it calculates current appreciation of off-plan projects in Abu Dhabi
Many of you have asked this question, wanted to clarify with full transparency. Yes we are aware of the fact that ADREC started publishing actual deal price (including premium) after 2025.

The ▲ % since launch figure is a weighted average of per-layout price appreciation, calculated directly from ADREC transaction records.
📋 Layout-level price sampling
For each unit type (Studio, 1BR, 2BR, etc.), Proprobin takes a sample of the earliest recorded sales as the launch baseline and a sample of the most recent sales as the current price reference.
Using a window of transactions rather than a single sale removes outliers and gives a statistically stable reference price.
📐 Price per sqm comparison
Appreciation is measured on price per sqm, not total sale price. This isolates true value change and removes distortion caused by different unit sizes across transactions.
Appreciation = (Current median AED/sqm − Launch median AED/sqm) ÷ Launch median AED/sqm × 100
⚖️ Sales-weighted overall figure
Each layout's appreciation is weighted by its share of total transactions. A layout with 500 sales influences the headline figure more than one with 50 — making the number representative of actual market activity.
Only layouts with at least 6 months of sales history are included to ensure statistical reliability.
📅 Daily data refresh
All figures are refreshed daily from the latest ADREC transaction feed. The launch price baseline is fixed at the earliest recorded sales; the current price window moves forward automatically as new transactions are registered.
⚠️ Note: Appreciation reflects registered transaction data only. Secondary market sales capture resale premiums. Developer incentives and service charge adjustments are not captured. This is an analytical tool, not financial advice.
