Timesheet Utilisation Calculator

Work out timesheet utilisation instantly with clear inputs, formula shown and shareable results.

About Timesheet Utilisation Calculator

Utilisation from timesheets is only as good as timesheet completion. Reporting unlogged hours alongside billable utilisation shows whether a low utilisation figure reflects genuine idle capacity or simply missing time entries.

Formulas

Billable utilisation

Utilisation % = Billable hours / Capacity hours x 100

Timesheet compliance

Compliance % = (Billable + Non-billable hours) / Capacity hours x 100

Worked example

With the default values below, Timesheet Utilisation Calculator returns Billable utilisation of 78.57%. Change any input above and every figure here is recalculated in your browser.

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 fees or charges 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

Why track non-billable hours at all?

Because they reveal where capacity goes — sales support, internal projects, admin — and make the case for reducing the ones that add nothing.

Should training count as billable?

No, but it should be a protected non-billable category with its own target, otherwise it is the first thing squeezed out.
