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.
Seasonal bills often rise because one or two high-load systems run longer, not because every device changed. For this page, the most useful checks are computers, gaming consoles, laundry, lighting, and schedule changes.
Compare the current bill with a milder month by daily kWh and all-in cost per kWh. If daily kWh jumped, usage is the likely driver. If daily kWh stayed flat, review rate and fee changes.
Useful checks

Common drivers include computers, gaming consoles, laundry, lighting, and schedule changes. Compare kWh usage, billing days, and the all-in rate before blaming one appliance.
Daily kWh is usually the better first comparison because billing periods can vary in length.
Start with total kWh, use the all-in electricity rate from the bill, and then estimate the major seasonal appliances separately.
