Core charging cost tools

EV Electricity Rate Comparison Worksheet

Compare two or three electricity-rate scenarios using monthly kWh so you can test flat rates, EV plans, and time-of-use plans.

Planning rule

Use your own rates, distances, climate, charger access, and driving pattern. These tools compare scenarios; they do not make vehicle, charger, utility, rebate, electrical, or financial decisions for you.

When this tool is useful

Compare two or three electricity-rate scenarios using monthly kWh so you can test flat rates, EV plans, and time-of-use plans.

It is designed for planning conversations, not for making a final decision. Enter the numbers that match your location, vehicle, charger access, driving pattern, and season. If a number is uncertain, run a low, middle, and high scenario instead of pretending one estimate is exact.

Example scenario

A cheaper overnight rate may help only if enough charging can actually be shifted into the lower-price period.

The point is not to copy the example. The point is to see which assumptions drive the result, then replace them with your own electricity rate, fuel price, distance, charging mix, weather, and vehicle efficiency.

Common mistakes to avoid

  • Looking only at the lowest advertised rate.
  • Forgetting delivery, taxes, fixed fees, or plan conditions.
  • Assuming every driver can charge overnight.

Educational-use disclaimer

These tools are for educational planning only. They use user-entered numbers and editable example assumptions to compare possible EV charging and ownership-cost scenarios. They are not quotes, electrical advice, vehicle recommendations, rebate advice, tax advice, legal advice, insurance advice, financial advice, or recommendations to buy, lease, install, charge, switch, or choose a specific provider.

Common EV Charging Cost Mistakes

Many charging-cost mistakes come from mixing rates, ignoring public charging, forgetting weather, or treating savings as guaranteed.
