Wow. Thanks so much for this. I had no idea how much water I used. Because I rent (and dont pay for water) I never really paid attention to it, but I use so much water to basically wake me up.

I use a lot of hot water in the evening. It helps me relax and puts me to sleep. I always wondered how much $ do I spend, because I really love long showers.

There are many more factors in determining the actual cost, such as the shower water temp, the cold water temp the water has to be raised from (much different from alaska to florida), and your water heater efficiency rating.

kins: Thanks for pointing these out as I forgot to include them in my post. This is just a first draft of this calculator. I am going to add a field for the cost of water and some of the other factors as mentioned. I currently used many default values for efficiency, water temperature rise and water cost that I will be sure to add to my post above. I am collecting more data on each state to make it more automated for the user on some of these values. I will also be adding some additional features like the ability to choose the time periods over which the calculations are made, but that is a little further down the road.

Hi Patrick,

Confirmed … as I commented on your other post … according to your calculator, my wife’s 30 minute showers cost us almost $3 a day … yikes.

I would thank you for Energy cal support. does this work with 230V/50Hz supply?
as i live in Sri lanka.
if you can supply a load cal system for above to use with 12V DC to 230V / 50Hz AC systems I am willing to buy it. I work with solar to AC power.

thanks

Hey, thanks for the info…I live with my brother and his son (2 1/2 men?)….my nephew takes 25 min showers (not sure what he;s doing in there for that long)….but we pay 5.8 cents per Kwh….so it’s not so bad…I thought that I was paying a lot more for his showers…turns out to be only 40 cents per shower….

I’m confused…is this based on one shower per day?

  Cass,
  
  I believe the calculator is a per shower basis, so if you shower 2 times a day at 15 minutes each, just multiply your result times 2.
  
  Thanks!

This is fantastic. One thing is that I think your assumption of $2/1000 gallons is really low. I know including water AND sewer (which is a valid cost) we pay .01/gallon in the City of Asheville, NC. That’s $10 for 1000 gallons.

Just some input. I do think it’s important to make it really clear that this is only per shower per day. The real numbers for the average family are 4-5 times that.

Hi there, this has really helped me with my economics class and I was wondering if it was possible to add the option of solar power and propane to the form of power.

Thanks!
