The Impact Calculator
One household can't move a price. A state full of them can.
Cutting a few gallons of gas a month feels like rounding error. But you're not one household — you're one of millions making the same call. Here's what the small stuff looks like at scale.

What that adds up to
Ohio has 4.8M households. If 35% of them cut 8 gallons of gasoline a month, here's the math.

Modeled estimate. Household counts are U.S. Census ACS 2023. Per-household use is a national average — EIA: ~1,000–1,100 gallons per household per year, spread across an average of two vehicles. Prices are current national averages adjusted by state price parity.
The math, in the open
Three numbers, multiplied.
There's no model magic here. The scenario is just three honest estimates stacked on top of each other — and you can change any of them.
1
Households
How many occupied homes the state has. Straight from the Census.
2
The habit
Units saved per household each month — the one number you control.
3
The price
Current average price, adjusted for what things cost in that state.
Zoom all the way out
The same habit, all 127M U.S. households.
Gasoline
$15B
a year, if a third of households save 8 gallons/month — carpooling or combining trips one day a week.
Electricity
$5.3B
a year, if a third of households save 60 kWh/month — a smart thermostat plus LED bulbs.
Eggs
$1.7B
a year, if a third of households save 1 dozen/month — buying the store brand instead of name-brand.
Milk
$1.1B
a year, if a third of households save 0.5 gallons/month — cutting one carton a month that usually gets poured out.
