Renovation cost per m²

Type the area and the rate. 40 × 800 gives 32 000 zł. 60 × 1000 gives 60 000 zł. 50 × 650 gives 32 500 zł. A product, not a full-gut quote.

Not a crew price list. The calculator multiplies area by the typed rate. A purchase price from the same pair lives on total price from price per m².

How it works

Renovation cost per m² in this calculator is the area times the unit rate. 40 × 800 gives 32 000 zł. 60 × 1000 gives 60 000 zł. 50 × 650 gives 32 500 zł. No grosz in the number.

The area field is the first factor. The rate field is the second. A reserve, an architect, and furniture wait in the optional block. In these three examples they stay empty, so the result does not add a buffer.

32 000 zł is not a 5500-per-metre article range. 60 000 zł does not know the walls. 32 500 zł is 50 times 650. The calculator does not load a labour list.

Total price from price per m² next door also multiplies area, but by a purchase rate: 50 × 8000 leaves 400 000 zł. Here a works rate. Price per m² divides, and does not multiply.

Type 40 and 800, then Calculate. A comma in 800.5 parses. A two-field sketch, not a site manager’s bill of quantities.

40 × 800 gives 32 000 zł. 60 × 1000 gives 60 000 zł. 50 × 650 gives 32 500 zł. Another rate at 40 changes 32 000.

Formula

cost = area × rate. Reserve = cost × percent / 100. Total = cost + reserve + architect × area + furniture, only from options.
