Shrinkage calculator

Where the paid hours actually go.

Shrinkage is the number most often guessed and least often measured. Break the hours down by category and the uplift factor follows — that is what turns required agents into rostered heads.

The formula

How this is calculated.

  1. 1Shrinkage = hours lost ÷ paid hours
  2. 2Uplift factor = 1 ÷ (1 − shrinkage)

Before you trust it

What this model assumes.

  • Whether breaks count as shrinkage depends on how your paid hours are defined. Be consistent between this figure and the one in your staffing model, or you will double-count.
