Performance Rating Distribution Calculator

Work out performance rating distribution instantly with clear inputs, formula shown and shareable results.

About Performance Rating Distribution Calculator

A guided or forced distribution allocates fixed shares to each rating so that ratings remain comparable across managers and the reward budget stays affordable. The bulk always sits at 'meets expectations', which is the rating most organisations struggle to communicate as genuinely positive.

Formulas

Meets expectations share

Meets % = 100% - Top % - Above % - Below %

Counts

Count per rating = Employees x Rating share %

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 whole numbers, 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

Is forced distribution a good idea?

It controls rating inflation and budget but damages trust when applied rigidly to small teams. Most organisations now use it as a calibration guide rather than a quota.

Why not rate everyone highly?

Because if everyone is exceptional the rating carries no information, and the merit budget cannot fund the increases the ratings imply.
