Estimate raw weekly staffing hours and FTE needed to cover a fixed number of posts continuously.
24/7 Coverage Calculator
Formula
Weekly hours = posts × 24 × 7; FTE = annual coverage hours ÷ annual hours per FTE
How to use the result
This is the mathematical floor before considering leave, training, absence, breaks, overlap and any minimum-qualification rules.
What the calculator does not know
These are operational arithmetic tools, not employment-law, collective-agreement, payroll, occupational-safety or human-resources advice. Breaks, rest periods, overtime, maximum hours, scheduling notice, minimum staffing and qualifications vary by jurisdiction, contract, sector and workplace; verify the rules that actually apply.
Improve the estimate
Keep the inputs used for the decision and compare the estimate with actual results. A simple calculator is most useful when it makes the assumptions visible enough to learn from the difference.
