How to Use the EV Charging Calculator to Estimate Your EV Charging?

Our EV Charging Calculator is easy-to-use and it will allow you to estimate the cost of charging your electric vehicle at home. Here's how to use it:

  1. Choose your car model: The first step is to select your car model from the drop-down menu. We have a wide range of models to choose from, so you can easily find your own vehicle.
  2. Set the charging level: Next, you'll need to set the charging level. This determines how quickly your vehicle will charge and is usually measured in kilowatts. You can choose from a range of charging levels to suit your needs.
  3. Set power delivery from preset or custom: Depending on your vehicle and charging station, you may have the option to select a preset charging level or customize the power delivery based on your own charger setting.
  4. Input electricity rates: Enter the current cost of electricity in your area. This varies depending on your location, charging time, and energy provider.
  5. Get results: Once you've entered all the necessary information, you can click "calculate" to get an estimate of your charging costs and time.

Features of Our EV Charging Calculator

Our EV charging calculator comes equipped with a range of features to help you estimate the cost and time it takes to charge your electric vehicle at home. These features include:

  • Car model selection: You can choose your specific make, model, and corresponding capacity of the EV battery from our vehicle list to ensure accurate calculations.
  • Battery level setting: You can set your desired battery level to determine how much charging is needed.
  • Pre-set & customizable electrical settings: You can choose from a range of pre-set power delivery options or customize your own to meet your specific charging needs.
  • Estimated cost and charging time: Get an estimate of how much charging will cost you and how long it will take to fully charge your electric vehicle based on your input.

How to Estimate the Cost of Charging an Electric Vehicle?

To calculate the cost of charging an electric vehicle, you need to know the battery size in kilowatt-hours and the cost of electricity per kilowatt-hour. The formula to calculate the cost to charge an electric vehicle from empty to full is simple:


The average cost of electricity in the US is around 10.5 cents per kWh, but this may vary depending on your state and local electricity provider.

Since the calculator above does all the calculations for you, all you need to do is to set the beginning and the end battery charging levels as well as the electricity price in order to get the final cost to charge the vehicle.

How to Calculate the Time It Takes to Charge an EV?

To calculate the time it takes to charge your electric vehicle, you need to know the battery size in kilowatt-hours, the charging power in kilowatts, and the charging efficiency. The formula to calculate the time it takes to charge an EV is as follows:


You should expect energy loss when using any charging equipment, it’s pretty normal. Most EV chargers in the market can manage to maintain a charging efficiency of around 90% to 95%.

What Is the Average Cost of an EV Home Charging per Charge?

The average cost of EV home charging per charge varies depending on the electricity rates in your area and the size of your car's battery. On average, it can cost between $5 to $15 to fully charge an electric vehicle at home.

The cost to charge your EV is surly and significantly lower than filling up a gas tank with petrol or diesel. We do have another online calculator for you to compare the cost between EVs and ICE vehicles.

Factors That May Affect EV Charging Costs

There are several factors that can affect the cost of charging an electric vehicle. Two of the most significant factors are the local electricity rates and the energy consumption of the vehicle. Here's a brief explanation of each:

Local electricity rates: The cost of electricity varies depending on where you live. Some areas have higher electricity rates than others, which can significantly impact the cost of charging your EV.

Energy consumption: The amount of energy your EV consumes will affect how much it costs to charge. Factors that can impact energy consumption include the size of the battery, the driving habits of the driver, and the efficiency of the vehicle's charging system.

Factors That May Affect the Charging Time

Charging time is an important consideration for EV owners, as it can vary depending on several factors. Here are three key factors that can affect charging time:

Charging Levels (Power Delivery): The charging level determines the rate at which the EV's battery is charged. The higher the power delivery, the faster the charging time. Level 1 charging (120 volts) is the slowest, while Level 3 (DC fast charging) is the fastest.

Battery Level: The amount of charge already present in the battery also affects charging time. Charging from 20-30% to 80% is the fastest while charging from 80% to 100% can take significantly longer due to the need to balance the battery's cells.

Ambient Temperature: The temperature of the battery can also impact charging time. Cold temperatures slow down the charging process, while high temperatures can reduce the battery's lifespan and increase the risk of overheating.
