Is my electricity use high?
Updated August 5, 2026 · based on EIA 2024 residential data · by Cali Energy
Is my electricity use high for California? The average California home uses about 503 kWh a month (EIA 2024) — well below the U.S. average of 863 kWh. As a rough guide, under ~350 kWh/mo is low, ~350–550 is moderate (the state average sits here), ~550–750 is above average, and over 750 kWh is high for the state. Air conditioning, a pool, an EV and home size all shift what counts as normal.

This is a Cali Energy editorial classification — not a government standard, a code threshold, or a determination of whether your home is efficient. Climate, household size, medical equipment, EVs, a pool, electrification, and behind-the-meter solar all move the number a lot.

The rates and figures this calculator usestap to verify
The tool compares your monthly kWh to two federal averages and places it in a usage band. Here are the exact reference figures it uses.
| California average, per month | 503 kWh |
| U.S. average, per month | 863 kWh |
| Low | under 350 kWh/mo |
| Moderate (state average ~503) | 350–550 kWh/mo |
| Above average | 550–750 kWh/mo |
| High | 750–1,000 kWh/mo |
| Very high | over 1,000 kWh/mo |
The 503 and 863 kWh averages are U.S. EIA 2024 figures. The bands are a Cali Energy editorial guide for context, not a government efficiency standard — a hot inland home with AC can be perfectly normal at 900 kWh.

Enter any monthly usage above to see its band and how it compares. A few reference points:
| Monthly use | Band | vs CA avg (503) | vs U.S. avg (863) |
|---|---|---|---|
| 300 kWh | Low | 40% below | 65% below |
| 500 kWh | Moderate | 1% below | 42% below |
| 900 kWh | High | 79% above | 4% above |
How this calculator works
It takes your average monthly kWh, compares it to the EIA’s 2024 residential averages for California (503 kWh) and the U.S. (863 kWh), and reports the percentage above or below each plus a plain-language band. It’s a quick context check, not a diagnosis — the same number means different things for a coastal condo and an inland house with central AC.
How to read your result
The band tells you where you sit for the state; the two percentages show how you compare to California and to the country. Californians use less than most Americans partly because of a mild coastal climate and efficiency rules, so being “below the U.S. average” is normal here — the more useful comparison is against the California figure.
What moves your usage the most
Air conditioning is usually the biggest driver in California, followed by electric heating or a heat pump, a pool pump, an EV, and simply home size and occupancy. If your number looks high, those are the first places to look — and the best candidates for solar to offset.
Common questions
Where do I find my monthly kWh?
It’s on every electric bill, usually near the usage graph. For a yearly view, average the last 12 months — summer AC months will read much higher than spring.
Why does California use less than other states?
A mild coastal climate means less heating and cooling, and decades of appliance and building efficiency standards hold usage down — which is why the state average sits well below the U.S. figure.
Is high usage bad?
Not necessarily — a large or all-electric home with AC and an EV will use more by design. High usage mainly means a bigger bill, and a bigger opportunity for solar to offset it.
How much would solar offset this?
That depends on your usage and roof. Feed your kWh into our “How many panels” and payback tools to size a system and estimate the savings.
