This Heating & Cooling Cost Calculator estimates monthly energy (kWh) and cost for heating or cooling a room. Enter area, usage hours, power per m² and system efficiency (COP) to compare different setups and estimate monthly bills. These are practical estimates — actual consumption depends on insulation, climate, thermostat, and system cycling.

Heating & Cooling Cost Calculator
Estimate monthly energy (kWh) and cost for heating or cooling a space using area, usage hours and system efficiency.
Typical defaults: Cooling 80–150 W/m²; Heating 50–120 W/m² — adjust for insulation.
COP ~3 for typical AC/heat pump. Electric resistive heater ~1.0.
How to use: Enter the room area (m²), how many hours per day the system runs, days per month, power per m² (W/m²), and system COP/efficiency. Click Estimate to see kWh per month and estimated cost.
Why use: Plan monthly bills, compare systems (heat pump vs resistive heater), estimate savings from insulation or more efficient units.
Benefits:
• Quick monthly cost estimate
• Compare different COP/efficiency values
• Helps budget and buy the right system
• Works offline & private
