Why Every Manager Needs a Calculator
Most management decisions are made on gut feeling. "That meeting feels important." "We should probably hire someone." "I'll just do it myself — it's faster." These decisions have real costs — in money, time, and team energy — but most managers never do the math.
That's the gap these calculators fill. When you can show your boss that a weekly status meeting costs $62,400/year, the conversation changes. When you can prove that an empty seat is costing $3,200/week in lost productivity, the hiring approval moves faster. Numbers don't just inform decisions — they win arguments.

How Managers Use These Calculators
Build a business case
Need to convince your boss to cancel a meeting, approve a hire, or invest in a tool? Show them the numbers. "This costs $X" is harder to argue with than "I think we should."
Reclaim your time
When you see that meetings eat 15 hours of your week or that you're spending 4 hours on tasks you could delegate — the motivation to change becomes visceral, not theoretical.
Make better decisions
Should you hire or delegate? Promote internally or recruit externally? Work overtime or hire part-time? These questions have numbers behind them. Use them.
