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 large house can fit many usage patterns. This page starts with a 1,800 kWh planning estimate for a larger home where heating, cooling, EV charging, pumps, or multiple high-load appliances can dominate usage.
If the bill looks high, check simultaneous high-load appliances, demand charges, tiered rates, pool pumps, EV charging, and long HVAC cycles. Then compare daily kWh and the all-in rate from the actual bill.
Start from the exact monthly kWh usage printed on the bill.

This page starts with 1,800 kWh as an editable planning estimate for a large house. Replace it with the actual kWh shown on your bill for a better answer.
Common things to check include simultaneous high-load appliances, demand charges, tiered rates, pool pumps, EV charging, and long HVAC cycles. Also compare billing days and the all-in rate before judging the total bill.
Use kWh first, then the all-in rate. Dollar totals can differ because of fixed fees, delivery charges, taxes, rate plans, and billing period length.
