How This KWh Cost Calculator Works

The calculator follows a simple and accurate formula used by energy providers in Ireland:

1. Convert watts to kilowatts
   Watts ÷ 1000 = Kilowatts (kW)

2. Calculate daily electricity usage
   kW × hours per day = kWh per day

3. Calculate cost
   kWh × electricity rate (€ per kWh)

The calculator then:

• Multiplies daily cost by 30 days for monthly estimates

• Multiplies daily cost by 365 days for yearly estimates

This ensures realistic electricity cost calculations based on Irish billing standards.
