Calculating electricity bill?

[Sunilyv]

I figured it out by taking the Hydros watt reading, multiplying by the hours it runs each day, then by the days in the month, and dividing by 1,000 to get kWh. Finally I multiply that by $0.33. For a 100 W heater on 24/7, that’s 72 kWh → $23.76. I also grabbed an octopus referral code when I switched providers.
