Time To Fill Calculator

Measure days from requisition approval to start date and the cost of the vacancy.

About Time To Fill Calculator

Time to fill includes the notice period, which time to hire excludes — and notice is often the larger component. Multiplying by the daily value of the role converts delay into a cost that can be weighed against recruiting spend. Vacancy cost usually dwarfs recruiting cost, which reverses the usual instinct to economise on agency fees at the expense of speed.

Formula

Time To Fill

Time to fill = days to hire + notice period; vacancy cost = days × daily value of the role

time to fill: Requisition approval through to the new starter’s first day
vacancy cost: Output forgone while the seat is empty
