What every flush, mile, and degree actually costs where you live.
Rates are 2025–26 averages: state residential electricity and natural gas, typical municipal water+sewer, and regional gasoline prices. Physical models use standard fixtures (1.6 gal flush, 2.0 gpm shower, 3.5 kW central A/C, 24/34 mpg city/hwy). Your utility bill is the ground truth; this is the honest estimate.
