School Cooling Cost Calculator — How It Works

Calculates the daily and monthly energy cost of running cooling equipment.

How it works

1. Enter your cooling equipment’s power rating in watts.
2. Enter how many hours per day you run it.
3. Enter your electricity rate per kWh.
4. The tool converts watts and hours into kilowatt-hours, then multiplies by your rate for daily and monthly cost.

Formula

Daily energy (kWh) = (Wattage × Hours per day) ÷ 1000
Daily cost = Daily energy × Rate per kWh
Monthly cost = Daily cost × 30

Example

A 1,500W cooling unit run 8 hours a day uses 12 kWh/day, costing about $1.80/day — or $54/month at $0.15/kWh.

Why this matters

Cooling costs add up quickly during hot months. Knowing the per-hour and per-month cost helps you weigh the cost of comfort against energy-saving options like fans, better insulation, or a higher thermostat setting.
