About the Live Load Calculator

Imposed (live) load for common occupancies and the factored design load with dead load.

Also known as: imposed load, occupancy load, floor loading calculator, design load.

How to use this calculator

  1. Enter occupancy, dead load, floor area.
  2. The result updates instantly as you type — press Calculate (or Enter) at any time.
  3. Review the breakdown shown under the main result.
  4. Use Copy result or Share to save the answer or send a link with your inputs.

Formula

Design load = 1.35 × dead + 1.5 × live (Eurocode ULS)

Worked example

Using the values pre-filled in the calculator above:

  • Occupancy: Office (2.5 kN/m²)
  • Dead load = 5 kN/m²
  • Floor area = 50 m²

the calculator returns:

  • Live load: 2.5 kN/m²
  • Unfactored total: 7.5 kN/m²
  • Factored design load (1.35G + 1.5Q): 10.5 kN/m²
  • Total live load on the area: 125 kN
