About Desk Sharing Ratio Calculator

Desk sharing works on average and fails at peak. The sharing ratio and average occupancy look comfortable, but the number that determines whether people can find a desk on a Tuesday is peak-day demand against desks available.

Formulas

Sharing ratio

Ratio = Employees / Desks available

Peak demand

Peak demand = Employees x Peak attendance %

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, fees or charges 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.

Frequently Asked Questions

What sharing ratio is workable?

Around 1.3 to 1.6 for hybrid teams with mid-week peaks. Above 2.0 needs anchor days or booking systems to avoid daily shortfalls.

Why does the peak matter more than the average?

Because a shortfall on two days a week is what employees experience and remember, regardless of how good the weekly average looks.
