Parkinson's Law cost.

Parkinson's Law cost calculator quantifies wasted time from work expanding to fill available time. 8-hour task that could be done in 4 = 50% efficiency, 4 hours wasted × 50/hour = 200 wasted per task × 250 days/year = 50,000 annual waste. Single biggest workplace efficiency lever - aggressive deadlines force focus.

Example: typical 8-hour workday tasks could realistically be done in 4 focused hours. 50% efficiency. 4 hours wasted × 50/hour value = 200/day. Annual: 50,000 productivity waste. Per Parkinson's Law (1955): 'Work expands to fill the time available for completion.' Aggressive deadlines force focus, eliminate procrastination.

Parkinson's Law solutions: (1) Hard deadlines (set tight, then enforce). (2) Time-boxing (90-minute focused work blocks). (3) Pomodoro technique (25-min sprints). (4) Calendar blocking. (5) Daily 'shutdown' time (ends work day). (6) 4-Hour Workweek principle (do most important things first). (7) Eliminate meetings without clear agenda + outcomes. Many workers' real productivity 4-5 hours of focused work daily despite 8-10 hour days. Improving by 10% = significant career advantage. Most underused productivity tool.

Quick example

With actual hours per task of 8 and minimum hours possible of 4 (plus hourly value of 50), the result is 50,000.00. Change any figure and watch the output shift — it's often more useful to see the pattern than to memorise the formula.

Which inputs matter most

You enter Actual Hours per Task, Minimum Hours Possible, and Hourly Value (£). Frequency and unit price pull the total in different directions. The biggest surprise for most people is how small recurring amounts compound into large annual figures — that's where this calculation earns its keep.

What's happening under the hood

Annual cost = wasted hours per task × hourly value × working days. The formula is listed in full below. If the number looks off, you can retrace the calculation by hand — that's the point of showing the working.

Using the result to decide

The figure gives you a threshold. Below it, paying someone else usually wins. Above it, doing it yourself usually wins. The number isn't destiny — some tasks are genuinely worth doing personally — but it sets the default.

What this doesn't capture

Hour-for-money math misses the tasks you enjoy and the ones that build skill. The number is an efficient-markets view of your time; real decisions about what to do yourself vs outsource should also weigh what you learn and what you enjoy.
