How to Find Your Electricity Price per kWh
Last reviewed: 2026-06-14
Quick answer
The best rate to use is the price you actually pay for the charging session, from your utility bill, charging app, station screen, or plan details. Charging prices change by location, provider, plan, time, fees, and taxes.
Use your utility bill for home charging
Look for cents per kWh or total energy charges divided by kWh used. Time-of-use plans may have different rates by hour, so the right value may be the off-peak, peak, or blended rate depending on when you charge.
Use the charging app or station screen for public charging
Public charging can include per-kWh prices, session fees, idle fees, congestion fees, taxes, or membership discounts. Use the price shown before the session when possible, then add fixed fees if the calculator has a fee field.
Use examples carefully
Example prices are useful for learning the formula, but they are not a substitute for current local rates. A sample rate can be helpful for testing the calculator, while a bill or app rate is better for budgeting.
FAQ
Should I include taxes and fees?
Include them when you want a closer estimate of the amount you will actually pay. If you only want to compare two energy rates, leave fixed fees separate so the energy cost difference is easier to see.
