Bill Check Guide
Why is my power bill higher than last month?
A higher power bill from one month to the next usually comes from weather, billing days, new usage habits, one device running longer, or a bill detail you did not expect.
Short answer: Your power bill is usually higher than last month because the billing period changed, the weather shifted, usage patterns changed, or one device or system ran more than usual.
Month-to-month comparisons are easy to misread.
A hotter or colder month, a longer billing cycle, or more occupancy can make a normal increase feel suspicious. The fastest way to cut through that is to compare days, weather, and kWh before you chase a product solution.
Look for one big change, not twenty tiny ones.
Bills usually move because of one or two big factors, not a dozen little ones. HVAC runtime, a new appliance, work-from-home hours, seasonal laundry changes, or a dehumidifier are better suspects than chargers and light switches.

What usually works best.
Start with the bill, then isolate the biggest usage change. If the jump is still unclear, measure the strongest suspects and use the calculator pages to frame what a normal month should have looked like.
