Understanding your price per square meter result
A unit price has no universal 'good' or 'bad' threshold — it depends entirely on the local market. The table shows how the figure is typically used in practice.
| Comparison outcome | Typical reading |
|---|---|
| Property's price per m² is below comparable local sales | Potentially priced below market — verify condition, tenure, and measurement basis before concluding it is a bargain |
| Price per m² is in line with comparable local sales | Priced consistently with the local market for that property type |
| Price per m² is above comparable local sales | Priced at a premium — justified only by factors the raw area misses (view, floor level, renovation, outdoor space) |
- The comparison row displays "—" when no second property is entered; it is optional and does not affect the main result.
- Per-area prices ignore everything that is not floor space: lot size, outdoor areas, parking, view, floor level, condition, and building amenities all move value without changing area.
- Area measurement conventions differ (gross external, gross internal, net internal/carpet area); comparisons are valid only when both properties are measured the same way.
- This is an educational comparison tool, not a valuation or appraisal.
What is price per square meter?
Price per square meter is a property's asking or sale price divided by its usable floor area in square meters. It is the standard unit-price metric in most countries that use the metric system, and it serves the same purpose that price per square foot serves in the United States: it removes size from the comparison so that a large and a small property can be judged on the same scale.
Appraisers and international property statistics agencies (such as Eurostat in its house price index methodology) use unit prices per square meter because raw property prices confound size with location and quality. Two apartments priced at 350,000 tell you little until you learn one is 120 m² (2,916.67 per m²) and the other is 85 m² (4,117.65 per m²) — the smaller one is markedly more expensive per unit of space.
Unit prices are most meaningful between genuinely comparable properties: same neighborhood, similar age, condition, and property type. Measurement conventions also matter — some listings quote gross area including walls and common areas, while others quote net internal or 'carpet' area, and mixing conventions distorts the comparison.
How to use this price per square meter calculator
- Enter the property's price (asking price, sale price, or valuation).
- Enter the floor area in square meters, using the same measurement convention you will use for any comparison property.
- Optionally enter a second property's price and area to compare — leave these at zero to skip the comparison.
- Read the price per square meter, the equivalent price per square foot (divided by 10.7639, the number of square feet in a square meter), and the comparison property's price per m² if provided.
- Worked example: a 350,000 property with 120 m² of floor area costs 2,916.67 per square meter, equivalent to 270.97 per square foot.
The formula behind price per square meter
The calculation is a simple division of price by area. The square-foot equivalent divides the per-m² figure by 10.7639, because one square meter equals 10.7639 square feet (from the exact definition 1 ft = 0.3048 m, so 1 m² = 1 ÷ 0.3048² sq ft).
The comparison result applies the same division to the second property's price and area. When no comparison property is entered (price or area left at zero), the comparison row shows a dash (—) rather than a number.
Common mistakes
- Comparing properties measured under different area conventions — a gross-area listing will look artificially cheap per m² next to a net-internal-area listing.
- Treating the lowest price per square meter as automatically the best deal, ignoring condition, floor level, outdoor space, and location micro-factors that area does not capture.
- Applying a per-m² figure from apartments to detached houses (or vice versa) — unit prices differ systematically by property type.
- Forgetting that land value dominates in some markets, so a small house on a large lot can show a misleadingly high price per square meter of building.
- Mixing units — dividing a price by square feet while reading the result as per square meter overstates the unit price by a factor of about 10.76.
常见问题
What is a good price per square meter?
There is no universal benchmark — price per square meter varies enormously between countries, cities, and even adjacent neighborhoods. The figure is useful relative to comparable local sales: a property priced per m² below similar recently sold homes in the same area may be attractively priced, while one above them carries a premium that should be explainable by condition, position, or features.
How do I convert price per square meter to price per square foot?
Divide the price per square meter by 10.7639, because one square meter contains 10.7639 square feet (from the exact definition 1 foot = 0.3048 meters). For example, 2,916.67 per square meter equals 270.97 per square foot. To convert the other way, multiply the per-square-foot price by 10.7639.
Why does the comparison result sometimes show a dash (—)?
The second property is optional. The comparison row computes Price_B ÷ Area_B only when both a comparison price and a comparison area greater than zero are entered; otherwise it displays "—" to indicate no comparison was requested. The main property's price per square meter and per square foot are unaffected.
Should I use gross or net floor area?
Either can work, but consistency is essential. Gross area (including internal walls and sometimes a share of common areas) produces a lower price per m² than net internal or carpet area for the same property. Appraisal standards such as RICS measurement guidance define these bases precisely; when comparing two properties, confirm both areas were measured on the same basis.
Does a lower price per square meter mean a better investment?
Not by itself. Price per square meter is a screening metric, not a valuation: it says nothing about rental yield, condition, tenure costs, future maintenance, or neighborhood trajectory. Investors typically combine unit-price comparisons with income measures (such as rental yield or price-to-rent ratios) and a physical inspection before drawing conclusions.
