The standardized figure is useful when properties have different sizes: a lower total price can still represent a higher unit cost if the usable area is much smaller. The tool also compares up to five properties, identifies the lowest unit cost, calculates the simple average and spread, and creates a current-state Excel workbook.\u003c\/p\u003e\n    \u003cp\u003eThe result is a screening metric rather than a complete valuation. Two homes with similar unit costs may differ materially in location, condition, floor plan efficiency, outdoor space, energy performance, renovation needs, lease terms, taxes, service charges, or expected maintenance. Use the unit-cost comparison to organize a shortlist, then evaluate the qualitative and cash-flow differences separately.\u003c\/p\u003e\n\n    \u003ch2\u003eHow should each input be used?\u003c\/h2\u003e\n    \u003ch3\u003eCost type\u003c\/h3\u003e\n    \u003cp\u003eSelect \u003cstrong\u003ePurchase price\u003c\/strong\u003e when comparing asking prices or agreed transaction prices. Select \u003cstrong\u003eMonthly rent\u003c\/strong\u003e when comparing recurring rent. The formula is identical, but the interpretation changes: purchase mode reports capital cost per area unit, while rent mode reports monthly occupancy cost per area unit. Do not mix purchase prices and monthly rents in the same comparison because the resulting unit costs would not share a common time basis.\u003c\/p\u003e\n    \u003ch3\u003eCurrency\u003c\/h3\u003e\n    \u003cp\u003eChoose the currency used by every entered amount. Changing the symbol does not perform a foreign-exchange conversion; it only changes formatting. Convert amounts externally before comparing properties listed in different currencies. Exchange rates can move quickly, so keep the conversion date consistent when cross-border comparisons are unavoidable.\u003c\/p\u003e\n    \u003ch3\u003eArea unit\u003c\/h3\u003e\n    \u003cp\u003eChoose square meters or square feet. When the unit changes, the calculator converts every current area value using 1 square meter = 10.7639 square feet. The cost-per-unit result changes accordingly, but the underlying property size remains the same.

Enter the full purchase price or monthly rent as a nonnegative number. Enter the interior floor area as a positive number in the selected unit. Avoid combining indoor area with balconies, garages, storage rooms, or land unless every listing uses the same convention. An inconsistent area definition can distort the comparison more than a small price difference.\u003c\/p\u003e\n    \u003cp\u003eThe example values are editable.

Reset clears the calculator to one empty property, removes added rows, and returns to USD and square meters.

A $410,000 property with 152 m² has a unit cost of about $2,697.37 per m², so the second property is slightly cheaper on a unit-area basis even though its total price is higher.

The average is a simple, unweighted mean of the valid property unit costs; it does not weight larger homes more heavily. The highest unit cost identifies the upper end of the comparison. The spread is the arithmetic difference between the highest and lowest unit cost. A zero spread means all valid properties have the same displayed unit cost, while a large spread signals that price, area, or both vary meaningfully.\u003c\/p\u003e\n    \u003ch3\u003eChart and comparison table\u003c\/h3\u003e\n    \u003cp\u003eThe horizontal bars visualize each property’s unit cost using the same scale. The legend reports the exact unit cost and the percentage premium over the current lowest-cost property. The table repeats the same model data with the original cost and area, allowing the comparison to be audited without relying on the chart. A 0.00% “Vs. lowest” value marks the benchmark property; positive percentages show how much more expensive another property is per unit of area.\u003c\/p\u003e\n    \u003ch3\u003eTotal compared area\u003c\/h3\u003e\n    \u003cp\u003eTotal compared area sums the floor area of valid properties.
