The electric bill has a customer charge, basic service charge, meter fee, or monthly account fee that stays flat each month.
A customer charge can set a floor under the electric bill. If you only look at total dollars, real kWh savings may look smaller than they actually are.
Check first
Find customer charge, basic service, account charge, or monthly service fee lines.
Check whether the fee is fixed or changes with billing days.
Compare kWh savings separately from fixed charges.
Look for minimum bill language that may overlap with fixed fees.
Practical savings moves
Estimate savings only on usage-based kWh and variable delivery charges.
Use fixed-charge math to set a realistic lowest bill.
Track monthly kWh even when the total dollar drop is modest.
Use the bill explainer to separate customer charge, supply, delivery, and taxes.
Avoid these mistakes
Do not expect lower kWh to remove a fixed customer charge.
Do not divide the whole bill by kWh without noting fixed fees.
Do not treat a fixed charge as an appliance problem.
