Enter the shower length, how many showers your household takes a day, the head you actually have and what heats the water. The calculator prices a single shower and the year of them.
A shower bill is two thin streams that add up: the water utility charge and the fuel that heated the water. Neither looks like much per minute, which is why the tenth minute keeps happening - the calculator prices it, and the last five minutes of a long shower turn out to be the cheapest ones to skip.
How to use
- Time one real shower - most people guess 5 minutes and take 9.
- Count every shower in the house for the household number, not just yours.
- Check the head for a 2.0 or 2.5 gpm stamp and pick the heater fuel; the verdict updates live.
Frequently asked questions
How much does a 10 minute shower cost?
On a standard 2.5 gpm head with gas water heating, about 60 cents - near a dollar with an older power head on an electric heater. A ten-minute habit for one person is around 200 dollars a year.
Is a 20 minute shower expensive?
It doubles the ten-minute number: a dollar or more each time, about 400 to 700 dollars a year for a daily taker. The first ten minutes carry the washing; the second ten are pure hot-water rental.
Do low flow showerheads actually save money?
Yes, mechanically: a 2.0 gpm WaterSense head moves 20 percent less water per minute, and the family of showerers saves about 2,700 gallons a year - the water charge and the heating charge both shrink. The calculator shows the per-shower gap.
Is electric or gas water heating cheaper for showers?
Gas heats the same gallon of hot water for roughly a third of the electric cost in most markets - the fuel select at the top flips the whole bill. If the house is on electric, shorter showers and a lower flow head pay back twice as fast.
What uses more water, a bath or a shower?
A typical tub holds 30 to 40 gallons filled; a ten-minute shower on a standard head runs about 25. Baths lose on short showers and win against the twenty-minute soaker - the shower vs bath page prices the crossover at your flow rate.
