Step 1
Confirm the billing period
Compare the number of billing days before comparing dollars. A 34-day bill can look high even when daily usage is normal.
Electric bill audit
Audit a high electric bill before changing your home.
Work through the bill in order: billing days, daily kWh, effective rate, fixed charges, major loads, and meter reads. The goal is to find the cause before spending money on fixes.
Quick worksheet
Billing days
Was this bill longer than the last bill?
kWh per day
Did daily usage rise, or only the dollar amount?
Energy rate
Did the cents-per-kWh supply price change?
Delivery and fees
Did fixed charges, riders, or taxes increase?
Major loads
Did cooling, heating, EV charging, or pumps run longer?
Meter read
Was the reading actual, estimated, corrected, or adjusted?
Step 2
Compare daily kWh
Divide monthly kWh by billing days. Daily kWh is the cleanest way to see whether usage really changed.
Step 3
Calculate the effective rate
Divide the full bill by kWh. If the effective rate rose, the issue may be supply, delivery, taxes, or fees rather than usage.
Step 4
Check fixed and delivery charges
Customer charges, delivery riders, minimum bills, and taxes can change the total without changing appliance behavior.
Step 5
List new or seasonal loads
Look for heat waves, cold snaps, guests, EV charging, pool pumps, dehumidifiers, portable heaters, and longer dryer runtime.
Step 6
Flag meter or estimate issues
Estimated reads, catch-up bills, meter swaps, and move-in/move-out adjustments can create a one-month spike.
Audit rule
Do not compare total dollars until usage and billing days match.
A useful audit compares daily kWh first, then the effective all-in rate, then individual bill lines. This prevents the common mistake of blaming appliances when the bill changed because of rate structure or billing period.
After you isolate the cause, use the savings calculator to estimate whether the fix is worth the cost.

Short answers for search visitors and bill-checking moments.
What is the first thing to check on a high electric bill?
Check billing days and daily kWh first. Those two numbers show whether the bill is high because of more usage or simply a longer billing period.
How do I know if the problem is my rate instead of my usage?
Divide the total bill by kWh and compare that effective rate with prior bills. If kWh is flat but the effective rate rose, review supply, delivery, tax, and rider lines.
Can an estimated meter read cause a high bill?
Yes. Estimated reads can underbill or overbill one month, and the next actual read may create a catch-up adjustment.
