If your electric bill jumps unexpectedly, compare the amount of electricity used before assuming the utility changed its price. A bill can rise because of higher kWh use, a longer billing period, a rate or fee change, a delayed estimated reading, or a combination. Start with the bill’s dates and line items, then compare usage with the same season last year.
Step 1: Compare kilowatt-hours and billing days
Find the kWh used and the number of days in each billing period. A 35-day bill will often be higher than a 28-day bill even if daily use is similar. Divide kWh by billing days to compare average daily use. Check whether the meter reading is actual or estimated, and contact the utility if the reading looks wrong or the next bill does not correct it.
Example: 1,050 kWh over 35 days and 840 kWh over 28 days both equal 30 kWh per day. The first bill covers seven extra days, so compare daily use before concluding that household consumption rose.
Step 2: If usage rose, look for a household change
- Heating or cooling: Extreme temperatures, a thermostat change, a heat pump or HVAC problem, or a system running longer can raise electricity use.
- Water heating: More hot-water use, a leaking hot-water fixture, or an electric water heater issue may affect consumption.
- New equipment: Space heaters, dehumidifiers, pool pumps, EV charging, new appliances, or extended use of electronics can add load.
- Household or building changes: More people at home, an addition, open windows while heating or cooling, or a change in insulation and air leakage can matter.
- Always-on equipment: A malfunctioning appliance or fan may run more than expected. Use the utility’s interval data or a qualified energy professional to identify large loads.
ENERGY STAR recommends comparing a home’s actual energy use over the last 12 months with similar homes, while noting that a home energy professional can help assess the causes of high bills or uncomfortable rooms. See how the Home Energy Yardstick works.
Step 3: If use is similar, inspect rates and charges
Look for changes to the energy rate, fixed customer charge, delivery charge, taxes, fees, fuel or purchased-power adjustment, and credits. A supplier’s energy price may be separate from the local utility’s delivery charges. If your plan is time-of-use, using electricity during a higher-priced period can increase the bill without changing total kWh; the specific hours and prices depend on the utility tariff. The U.S. Department of Energy explains how time-variable rates work in its time-variable pricing guide. Ask the utility to explain any unfamiliar item and when a rate change took effect.
EIA explains that its reported average retail price includes generation, transmission, distribution, taxes, and fees, but is not the same as a rate applied to one customer’s specific plan. See EIA’s explanation of state electricity prices and utility rates.
Step 4: Check for billing or meter issues
Compare the current meter reading with the number on the bill if your meter is accessible and safe to read. Do not open electrical equipment or touch wiring. Ask the utility whether the bill used an estimated reading, whether a prior estimate was reconciled, or whether a meter test is available. Keep the bill, meter photos if safe, and any case number.
What to ask your utility
- Was this bill based on an actual or estimated meter read?
- Did the billing period, rate, supplier, or fee schedule change?
- Can you provide daily or hourly usage data and compare it with the prior year?
- Is there a payment plan, budget billing option, or energy audit, and what are its terms?
- What steps can I take if I believe the bill or meter reading is incorrect?
Reduce future bills safely
Once you identify whether usage or charges changed, choose a step that addresses that cause. A utility energy audit can point to insulation, HVAC, water-heating, or equipment opportunities. Compare the cost and expected savings before purchasing equipment, and check whether incentives are currently available with your utility or government program. Do not bypass breakers, meters, or safety controls.

Compare your bill with EIA’s 2025 average monthly electricity bill by state. A statewide annual average cannot diagnose your home’s bill. For a current price comparison, see the EIA July 2026 electricity price table.
