I have just bought a bouncy castle for my children, its not too big, just something for them to play with in the summer. It came with a 400w air pump which keeps the bouncy castle constantly inflated.
I am worried about how much money it will be costing me to run. Say the children have this pump on to keep their bouncy castle inflated for 4 hours a day, and they want it up 4 times in a week, I'm worried that my electric bill is going to be sky high.
How much money will it cost me to run the 400w air pump, per hour??

Need to know how much you pay per kWhr of electricity. For example, a 400 w motor will consume 0.4 kWhr/hr. Multiply this by 4 hours a day times 4 days per week times 4 weeks per month and you will use about 25 kWhrs/month to operate the pump. Suppose you pay $0.25 per kWhr (probably a high estimate - I pay ~ $0.12/kWhr including fees and taxes). So, using $0.25 per kWhr, your electric bill would increase by about $6 a month.

Take a look at you electricity bill and note the cost your paying for each kwh (kiloWhour) 1000w/h. If for example your paying $50 per kwh. it would cost you $50 to run a 1000w motor for that hour. So multiply you answer by 0.4
Though a 400w motor will vary by way of its application you will have very close answer.

How much do you pay for a kWh of electricity? As a guide, you will get two and a half hours use for one kWh

Surely that depends on how much you're paying for electricity?
