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 300 kWh month can come from a low-usage apartment, efficient home, seasonal vacancy, or small household. The dollar amount changes quickly when the all-in rate includes delivery, fixed customer charges, taxes, and utility riders.
For a cleaner comparison, divide usage by billing days. A 35-day bill can look high even when daily kWh stayed normal.

The cost depends on the all-in electricity rate. Enter the energy rate, delivery charges, fixed fees, and taxes from your bill to estimate the total.
300 kWh may fit a low-usage apartment, efficient home, seasonal vacancy, or small household. Compare usage per billing day before deciding whether the month is unusually high.
Look for fixed customer charges, delivery riders, taxes, demand charges, tiered rates, a longer billing period, or a rate that changed mid-cycle.
