Quick answer
Cut your electric bill by checking your tariff rate plan, running heavy appliances during off-peak hours, and swapping old devices for efficient models. A tariff rate plan sets the price you pay per unit of power used. Rates ranged from about 12 cents per kWh in Louisiana to 48 cents per kWh in Hawaii in July 2026. So the savings from each step depend on your local utility rate.
Step 1: Find Your Rate and Understand What Drives the Bill
Before changing any behavior, pull out your most recent electric bill and find two numbers: your rate in cents per kWh and your total kWh used for the billing period. Your total charge for energy is simply those two numbers multiplied together, plus any fixed customer charge your utility adds each month regardless of usage.
According to EIA data for July 2026, residential rates across US states ranged from 12.72 cents per kWh (Louisiana) to 48.00 cents per kWh (Hawaii), with a national average of 18.31 cents per kWh. That spread matters a lot. A reduction in monthly usage saves much more in Hawaii than at the national average rate. Your bill’s tariff schedule code, printed on the statement itself, tells you exactly which rate applies to you.
Illustrative example (checked arithmetic): Suppose your bill shows 900 kWh used and a rate of 18 cents per kWh, plus a $12 fixed customer charge.
- Energy charge: 900 kWh × $0.18 = $162.00
- Fixed customer charge (see your bill for your amount)
- Subtotal before taxes and riders (see your bill for your amount)
If you reduce usage to 700 kWh, the energy charge drops to 700 × $0.18 = $126.00, saving $36 on that line item alone. Rates used here are illustrative; use the cents-per-kWh figure printed on your own bill for an accurate calculation. To understand exactly what a kWh represents on your statement, see kWh explained: what it means on your electric bill.
Step 2: Check Whether Your Rate Plan Fits Your Habits
Many utilities offer more than one residential rate plan. The two most common are a flat (or tiered) rate and a Time-of-Use (TOU) rate.
Under a flat or tiered rate, you pay the same cents-per-kWh price (or a stepped price after a baseline allowance) no matter when you use electricity. Under a TOU rate, the price per kWh changes depending on the time of day. TOU pricing sets electricity prices for specific time periods in advance, typically not changing more than twice a year, so you can plan around them. On-peak windows (often weekday afternoons and evenings) carry a higher rate; off-peak windows (nights, early mornings, weekends) carry a lower rate.
TOU works in your favor only if you can actually shift flexible loads, such as running the dishwasher, washing machine, or electric vehicle charger, to off-peak hours. If your household’s heaviest use is fixed to peak hours (for example, cooking dinner at 6 p.m. every night), TOU may not reduce your bill. Ask your utility for a bill comparison using your actual usage history before switching. For a deeper look at how TOU windows and rates work, see Time-of-Use electricity: pay less by timing your usage.
Step 3: Shift Flexible Loads to Off-Peak Hours
If you are on TOU or considering it, the practical action is to move appliances that run on a timer or can wait a few hours. Common candidates include:
- Clothes washers and dryers (use a delay-start feature if available)
- Dishwashers (run after 9 p.m. or before 7 a.m., depending on your utility’s off-peak window)
- Electric vehicle charging (schedule overnight charging through the vehicle’s app or a smart charger)
- Pool pumps (if applicable, set the timer to run during off-peak hours)
Even on a flat rate, running high-wattage appliances during cooler parts of the day reduces air-conditioning load, which indirectly lowers total consumption.
Step 4: Use the EnergyGuide Label to Replace Inefficient Appliances
When an appliance is aging or failing, your replacement choice affects your bill for years. Look for the yellow EnergyGuide label before you buy. This label is required on most major home appliances, such as refrigerators, dishwashers, clothes washers, water heaters, and central air conditioners. The label shows the model’s estimated annual energy use in kWh and an estimated annual operating cost.
One important caveat: the operating cost shown on the label is only an estimate, based on typical use and a national average energy price. Your actual cost depends on how you use the appliance and your local rate. To get a more accurate figure, multiply the label’s annual kWh figure by your own rate in dollars per kWh.
Illustrative example (checked arithmetic): A label shows a set number of kWh per year. Multiply that by your local rate per kWh.
- Your estimated annual cost: 500 × $0.22 = $110 per year
- A competing model uses 350 kWh per year: 350 × $0.22 = $77 per year
- Difference: $33 per year
Over ten years, that gap adds up (not accounting for rate changes). This comparison helps you decide whether a higher purchase price for the efficient model pays off over time. Rates and usage patterns are illustrative; use your own bill figures.
The EnergyGuide label also lets you compare a model against similar appliances. You can see whether a product is near the efficient or inefficient end of its category. Look for the ENERGY STAR label too. Products with that label must meet energy efficiency guidelines set by the US Environmental Protection Agency. Sellers of energy-saving products have a financial interest in promoting their own claims. Always cross-check those claims with the EnergyGuide label and independent reviews.
Step 5: Ask About Rebates Before You Buy
Your utility or state may offer cash rebates, low-interest loans, or other programs for buying energy-efficient products. These programs are not universal, and amounts vary. Before buying a new appliance, contact your utility’s customer service line. You can also check a free online tool called DSIRE. DSIRE stands for the Database of State Incentives for Renewables and Efficiency. It shows what programs are available in your area. A rebate can meaningfully offset the upfront cost of a more efficient model.
Step 6: Verify Your Meter Read and Billing Period
A bill that seems suddenly high may not reflect a change in your habits at all. Check these items on your statement before assuming a problem:
- Billing period length: A 34-day cycle produces a higher bill than a 28-day cycle even at identical daily usage. Divide total kWh by the number of days to get your daily average, then compare that figure month to month.
- Estimated vs. actual read: Look for a code such as “E,” “EST,” or “ESTIMATED” next to the meter reading. An estimated read uses historical data and may be corrected on the next actual read, resulting in a catch-up charge or credit.
- Rate change: Utilities adjust tariffs periodically. Even a small rate increase of 1 cent per kWh can noticeably raise your monthly bill. Check your bill’s rate line against the prior month.
To learn how to read your meter yourself and verify the utility’s reading, see electric meter reading: dial, digital, and dual-rate.
A Common Mistake: Assuming a Higher Bill Always Means a Fault
A higher bill does not automatically mean a leak, a broken appliance, or a meter error. Seasonal rate adjustments, a longer billing cycle, an estimated read correction, or more heating and cooling days can all raise the total. Work through the diagnostic steps above before calling a technician. If you still cannot explain the increase after checking the billing period, the meter read type, and the rate, contact your utility’s billing department. Ask for a meter test or a detailed usage history.
When to Get Professional Help
If your daily kWh use has genuinely spiked with no change in behavior or season, something may be drawing power continuously. A malfunctioning appliance, a failing HVAC system, or a wiring issue could be the cause. A licensed electrician can find phantom loads or faulty equipment. If you think your meter is inaccurate, you have the right to request a meter test from your utility. Most state public utility commissions require utilities to do this test at no charge, or for a refundable fee. If a billing dispute stays unresolved, file a formal complaint with your state’s public utility commission before any service termination occurs.
Frequently asked questions
How do I calculate what a specific appliance costs me per month?
Use the formula: kWh = Watts × hours of use ÷ 1,000. Then multiply kWh by your rate in dollars per kWh. For example, if an appliance runs 4 hours a day, find its wattage on the label, then do the math. At 18 cents per kWh (illustrative), even moderate daily use adds up fast. Use your own bill's rate for an accurate figure.
Does Time-of-Use pricing always save money compared to a flat rate?
Not always. TOU saves money only if you can shift flexible loads, such as laundry or dishwashing, to off-peak hours. If your heaviest usage is fixed to on-peak windows, you may pay more than on a flat rate. Ask your utility for a bill comparison using your actual usage history before switching rate plans.
What appliances are required to carry an EnergyGuide label?
EnergyGuide labels are required on boilers, ceiling fans, central air conditioners, clothes washers, dishwashers, freezers, furnaces, heat pumps, pool heaters, refrigerators, televisions, water heaters, and room and portable air conditioners. Not all appliances are covered. If you do not see a label, check inside the unit or on the manufacturer's website.
Why does my electric bill vary so much from month to month even when I think my usage is the same?
Several factors can shift the total without a change in habits: a longer billing cycle (34 days vs. 28 days), a rate adjustment, an estimated meter read followed by a correction on the next actual read, or seasonal heating and cooling demand. Divide your kWh by the number of billing days to get a daily average and compare that figure across months.
How do I find out if my utility offers rebates for energy-efficient appliances?
Contact your utility's customer service line directly, or check DSIRE at dsireusa.org. DSIRE is the Database of State Incentives for Renewables and Efficiency. Rebate programs vary widely by utility and state, and some are time-limited. Always check before you purchase, not after.
