Calculate your household's daily, monthly, and yearly water consumption
US average is $2-6 per 1000 gallons
Most people have no idea how much water they actually use. We turn on the tap and water comes out—until the bill arrives and we wonder why it's so high. Understanding your water usage is the first step to managing it.
The average American household uses about 300 gallons per day. But that varies enormously based on family size, habits, fixtures, and whether you have water-hungry appliances or a thirsty lawn. Some families use twice the average; others use half.
Our water usage calculator helps you estimate your household's consumption based on actual activities. You might be surprised where all that water goes—and where the biggest opportunities for savings lie.
We estimate your usage based on typical consumption for household activities:
Know what to expect on your water bill and plan accordingly.
If your calculated usage is much lower than your metered usage, you might have a leak.
See which activities use the most water so you can focus conservation efforts where they'll have the biggest impact.
Measure the impact of changes like low-flow fixtures or shorter showers.
Mistake: Underestimating outdoor use
Solution: Lawn irrigation can double your summer water bill. An average sprinkler uses 1,000+ gallons per hour.
Mistake: Ignoring hidden leaks
Solution: Check your meter before and after a 2-hour period of no water use. If it changed, you have a leak.
Mistake: Not accounting for guests
Solution: Holiday gatherings and houseguests can significantly spike water usage. Plan for temporary increases.
Mistake: Forgetting about softener backwash
Solution: Water softeners use 50-100+ gallons per regeneration cycle, usually every few days.
High water usage sometimes indicates plumbing problems:
About 300 gallons per day or 9,000 gallons per month for a family of four. This includes all indoor and outdoor use.
Toilets (24%), showers (20%), faucets (19%), washing machines (17%), and leaks (12%) are the biggest indoor users. Outdoor irrigation can exceed all indoor use combined.
Check your water meter, ensure no water is being used for 2 hours, then check again. If the meter moved, you have a leak. Also check your bill for unexplained increases.
Low-flow toilets save 4,000-16,000 gallons per person annually. Low-flow showerheads save about 2,700 gallons per person. A family of four can save 20,000+ gallons yearly.
