Calculate Weekly Coverage Hours Before Estimating Staff

Multiply simultaneous positions by operating hours. Two continuously occupied positions across a 24/7 week require 336 productive coverage hours.

Quick answer

Multiply simultaneous positions by operating hours. Two continuously occupied positions across a 24/7 week require 336 productive coverage hours.

Build the workload input

There are 168 hours in seven days. Two positions require 2 × 168 = 336 coverage hours before allowance for training, leave or absence. If operating hours vary by day, calculate each day separately.

Convert coverage into FTE

At forty scheduled hours and 20% shrinkage, each scheduled FTE supplies 32 productive hours. The 336-hour requirement therefore needs 10.5 scheduled FTE. Rounding to eleven full-time people gives a starting estimate.

What the estimate cannot solve

Rest requirements, skill mix, shift overlaps and breaks can prevent a simple headcount from covering every interval. Build the roster after estimating capacity, and check the busiest intervals explicitly.

Try it with your numbers

Convert workload hours into productive and scheduled full-time equivalents.

Frequently asked questions

How many hours does one continuously covered position require?

A complete seven-day week contains 7 × 24 = 168 coverage hours. This is the position requirement before employee absence or other shrinkage is considered.

Do handovers add to the requirement?

They can. If both outgoing and incoming staff must overlap, include that overlap in the workload. Do not assume a continuous single-position count already includes double staffing.

How many weekly person-hours does one continuously staffed position need?

Seven days × 24 hours = 168 coverage hours before adding relief for unavailable time. Requiring two people continuously doubles the coverage requirement to 336 person-hours.

Check the assumptions against the FTE & Headcount Calculator and keep the inputs alongside your result. For a discrepancy, send an anonymous worked example rather than private employee records.
