What this calculator is doing
It separates usage-based energy cost from the charges that stay on the bill even when usage drops. That all-in effective rate is often higher than the advertised kWh rate.
A 3-bedroom house can fit many usage patterns. This page starts with a 1,000 kWh planning estimate for a single-family home with central HVAC, laundry, kitchen appliances, lighting, and several occupied rooms.
If the bill looks high, check central air conditioning, heat pumps, electric dryers, pool pumps, dehumidifiers, and attic insulation. Then compare daily kWh and the all-in rate from the actual bill.
