FAQ

Where do I find my electricity rate?

Check your utility bill — it lists a per-kWh charge. In the US it typically ranges from $0.10 to $0.30/kWh.

Are the monthly estimates accurate?

They assume consistent daily usage for 30 days. Real bills vary with seasonal usage, tiered pricing, and demand charges.

Does this include standby power?

No. Most electronics draw a small amount of power even when off. You can estimate standby cost by entering 1-5 W as the wattage.
