About Fitout Cost Estimate Calculator

Office fitout is priced per square foot by specification tier, then uplifted for contingency and professional fees. Contingency of five to ten percent is standard because fitout works around existing base building conditions that are rarely as documented, and fees run five to eight percent for design and project management.

Formula

Fitout cost

Total = area x rate x (1 + contingency) x (1 + professional fees)

Assumptions and limits

  • The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax or compounding frequency into account.
  • Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

What is excluded from a rate per square foot?

Usually furniture, IT and audiovisual equipment, and any base building upgrades such as extra cooling capacity. Those can add another thirty percent, so the basis must be stated.
