- Electricity per load = 1.2
- Electricity price per kWh = 0.3
- Water per load = 50
- Water price per cubic metre = 2
- Loads per week = 4
- Electricity per load = 1.2*0.3 = 0.36
- Water per load = 50/1000*2 = 0.1
- Cost per load = 0.35+0.36+0.1 = 0.81
- Annual laundry cost = 0.81*4*52 = 168.48
- Loads per year = 4*52 = 208
