California Calculator
Control your energy costs
Updated for 2025 with real California rates, brackets, and regulations
California has some of the highest electricity rates in the continental United States, with PG&E averaging $0.38/kWh, SDG&E at $0.42/kWh, and SCE at $0.35/kWh — roughly 2-3x the national average of $0.16/kWh. California utilities use tiered rates (higher usage = higher rate) and Time-of-Use (TOU) pricing where peak evening hours (4-9 PM) cost 50-100% more than off-peak. LADWP (LA's municipal utility) is notably cheaper at $0.28/kWh. This calculator estimates your monthly bill by provider, home size, and rate structure.

Frequently Asked Questions
Why is electricity so expensive in California?
Wildfire liability costs (PG&E's $30B+ bankruptcy), infrastructure upgrades, clean energy mandates, decommissioned nuclear (Diablo Canyon), transmission costs across vast distances, and regulatory overhead. These costs are passed to ratepayers.
What is Time-of-Use (TOU) pricing?
TOU rates charge more during peak demand (typically 4-9 PM) and less during off-peak hours. PG&E's TOU peak rate is $0.50+/kWh vs $0.25/kWh off-peak. Running appliances (laundry, dishwasher, EV charging) off-peak saves significantly.
Which California utility is cheapest?
LADWP (Los Angeles) at ~$0.28/kWh is notably cheaper than the big three IOUs. PG&E (~$0.38/kWh) and SDG&E (~$0.42/kWh) are the most expensive. Municipal utilities are generally 20-40% cheaper than investor-owned utilities.
How can I reduce my California electric bill?
Switch to TOU rates and shift usage to off-peak, install solar (payback 5-8 years at CA rates), use a smart thermostat, switch to LED lighting, consider battery storage for TOU arbitrage, and check CARE/FERA discount programs for low-income.
What are CARE and FERA programs?
CARE (California Alternate Rates for Energy) provides 30-35% discount on electric bills for low-income households. FERA (Family Electric Rate Assistance) provides 18% discount for slightly higher income families (up to 250% FPL).
