Formula
- Use the units shown beside each field.
- Results update automatically whenever you change an input.
- Displayed values use up to four decimal places, or scientific notation for very small or large numbers. Calculations use standard floating-point arithmetic; exact integer and fraction tools identify their own precision rules.
- All prices are supplied by you. Includes only listed cost components. Quantity estimate only. Confirm actual dimensions, openings, cutting patterns and supplier specifications. No structural design or code-compliance assessment.
Example Calculation
- Area: 50 m²
- Thickness: 0.1 m
- Concrete price: 120 currency/m³
- Labor and finishing: 20 currency/m²
- Fixed charges: 100 currency
50 m² at 0.1 m thickness uses 5 m³; the entered material, labor and fixed rates total 1700.
Frequently asked questions
How do I use this calculator?
Enter area, thickness, concrete price, labor and finishing, fixed charges. The result updates automatically. Use Reset to restore the example values.
What method does it use?
cost=area × thickness × concrete price + area × labor rate + fixed charges.. All prices are supplied by you. Includes only listed cost components. Quantity estimate only. Confirm actual dimensions, openings, cutting patterns and supplier specifications. No structural design or code-compliance assessment.
Why might a rounded result differ?
The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.
Are my inputs saved online?
No. This calculator processes your inputs in your browser. A recently used list stores only calculator names on this device, not your entered values.
