What this means
This calculates daily kWh from wattage and hours, multiplies by days per week, and annualises the cost at your chosen kWh rate.
Formula used
annual_kwh = (watts / 1000) x hours_per_day x days_per_week x 52.
Worked example
A 2500W tumble dryer used 1.5hrs/day, 4 days a week at £0.29/kWh costs £226.20/year.
