Price per square foot is price divided by area. That makes it easy to calculate and easy to misuse: if the area basis or price type changes between two records, the apparent gap may be an arithmetic artefact. This guide shows how to check the denominator, define a comparable sale and keep ownership costs outside the headline ratio.
First identify the price and the area
Write down the actual price used in the calculation. Is it an asking price, developer offer, signed contract amount or registered transaction? Those are not interchangeable. Write down the stated floor area, its unit of measure, the source document and what is included. Ask for the unit plan and the area recorded in the contract or registration material rather than copying a portal's field without checking it.
ADREC's published registration collection includes Abu Dhabi area-measurement material. That does not establish that every brochure, listing, service-charge invoice and title record uses an identical denominator. Resolve the particular unit's documents and measurement basis before comparing two ratios. Balconies, terraces, walls and parking may require separate treatment; do not infer their inclusion from an unexplained “built-up” or “net” label.
Here is an illustration, not an Abu Dhabi transaction or a typical market spread. If a hypothetical home costs AED 2,000,000, dividing by 1,000 square feet gives AED 2,000 per square foot; dividing the same price by 800 square feet gives AED 2,500. The home and price did not change. The only change was the denominator. Record which of the two areas, if either, the relevant property document supports. Do not apply an assumed gross-to-net conversion percentage across buildings.
Match homes before comparing ratios
A district average combines apartments, villas and very different projects. Even within one tower, a studio and a large family apartment need not have the same unit price or per-area ratio. Start as narrowly as the available evidence allows: same project or building, same property and sale type, similar size and layout, and a close transaction period. Then note floor, orientation, view, condition, tenancy and incentives where the data actually discloses them.
ADREC Market Data provides recent sales filters, including property and project dimensions. Save the filter set and extraction date. A registered sale can establish a reported transaction; it does not disclose every feature that explains its price. Ask a valuer to inspect material differences when a decision depends on them. Do not convert an unfiltered district median into a valuation for one unit.
A comparison that can be audited
| Field | Subject home | Comparable A | Comparable B |
|---|---|---|---|
| Price basis and date | Asking or registered; date | Same distinction | Same distinction |
| Area and document | Number, unit and source | Same area basis verified? | Same area basis verified? |
| Property and sale type | Apartment, villa; primary or resale | Match or difference | Match or difference |
| Project and layout | Exact phase and layout | Match or difference | Match or difference |
| Floor, view and condition | Observed or documented | Known or unknown | Known or unknown |
| AED per square foot | Price divided by area | Recalculate | Recalculate |
| Exclusions | Fees, incentives, parking and terms | Document differences | Document differences |
If a comparable lacks a reliable area, calculate no ratio for it. If the area is in square metres, convert the area first and label the conversion; do not compare AED per square metre with AED per square foot. Keep the raw price and area visible beside the calculated result so another reader can reproduce it.
Explain the difference instead of declaring a bargain
A lower ratio may reflect a larger denominator, a different sale type, a less desirable outlook, deferred repairs or an older transaction. A higher ratio may reflect different attributes, but neither direction proves the seller's position is justified. Ask which observed difference could explain the gap, then obtain evidence. If the sample is too sparse or too unlike the subject home, the honest result is “no reliable comparison,” not a target price.
Service charges, cooling, transaction fees and future works sit outside the purchase-price-per-area formula. Get those costs for the actual unit and review them separately. Do not quietly add or subtract them from a registered transaction price while claiming to compare registered AED per square foot. This article is not financial, investment or valuation advice. For a material purchase decision, use verified documents and a qualified professional's property-specific assessment.
