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.
