Core charging cost tools

Time-of-Use Charging Planner

Plan how much of your charging can realistically happen in each price period and estimate a blended charging rate.

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

Plan how much of your charging can realistically happen in each price period and estimate a blended charging rate.

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.

What blended electricity rate am I really paying for EV charging?

Example scenario

A driver may expect mostly off-peak charging but discover weekend trips and errands push some charging into higher-cost hours.

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

  • Putting 100% of charging in the cheapest period without checking real habits.
  • Ignoring charger speed.
  • Forgetting that heat or cold can change kWh needed.

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.
