# Tesla Charging Cost Calculator

This Tesla charging cost calculator will help you estimate the cost to charge a Tesla. The charging cost depends on factors like how much is your Tesla's **battery capacity**, and to what **level** you are charging it. In addition to this, the calculator also covers calculation of **driving cost**. If you have questions like how much does it cost to charge your Tesla, read on to understand how to calculate the charging cost.

## How much does it cost to charge a Tesla?

The charging cost of a battery can be calculated for a battery having capacity `C`

and is charged `$R`

per kWh, is given by:

`P = C * R`

,where `P`

is the total cost to fully charge the battery.

Now, you can also determine the cost of electricity to drive `X`

miles in your electric car. For a car having a battery with capacity `C`

kWh and consumes `E`

kWh/100 miles (ca. 161 km), the electricity cost can be written as:

`E`_{C} = X * E * R / 100

,where `E`

is the electricity cost for your trip._{C}

## Using the Tesla charging cost calculator — How much does it cost to fully charge a tesla?

Follow the steps below to estimate the charging cost:

- Step 1: Enter the
**battery capacity**`C`

in kWh. - Step 2: Insert the
**per-unit cost**of electricity, i.e.,`R`

. - Step 3: Tesla charging cost calculator will now use the equation above to return the cost to
**fully charge**the battery.

Follow the steps below to determine the electricity cost for your trip:

- Step 1: Enter the
**driven distance**,`X`

. - Step 2: Insert the
**per-unit cost**of electricity, i.e.,`R`

. - Step 3: Fill in the
**efficiency**of your vehicle, i.e., energy consumed in kWh per 100 miles,`E`

. - Step 4: Tesla charging cost calculator will then return the cost of your trip.

## Example: How to calculate Tesla charging cost?

Find the charging cost for your Tesla having a battery capacity of 80 kWh with the unit cost given as $0.15 per kWh. Also estimate the electricity cost for a 100 miles trip, given the efficiency is 160 kWh/100 miles.

- Step 1: Enter the battery capacity
`C = 80 kWh`

. - Step 2: Insert the per-unit cost of electricity, i.e.,
`R = $0.15/kWh`

. - Step 3: The cost to fully charge the battery:

`P = C * R = 80 * 0.15 = $12`

Therefore, the cost to fully charge a battery is $12. Now let's find out the trip cost. To find the trip cost:

- Step 1: Enter the driven distance,
`X = 100 mi`

. - Step 2: Insert the per-unit cost of electricity, i.e.,
`R = $0.15/kWh`

. - Step 3: Fill in the efficiency of your vehicle, i.e., energy consumed in kWh per 100 miles,
`E = 160 kWh/100 mi`

. - Step 4: The cost of your trip is:

`E`_{C} = X * E * R / 100 = 100 * 160 * 0.15 / 100 = $22.50

The cost of the trip is $24 and since the battery capacity is 80 kWh, this trip cost is for about 2 times charging the battery.

Now, not everyone charges their car to full in one go; therefore, you can use the plot below to estimate the charging cost for different battery levels. The charging level interval is set to 10% for the plot based on your convenience. Say, for the case above you only charged the battery to 75%, then **set the interval** to 5% and hover the mouse over to the 75% mark to see the cost associated with it, i.e., $9.

## FAQ

### How to calculate charging cost for a trip?

To calculate the charging cost:

**Multiply**the driven distance with vehicle efficiency (kWh/100 miles).**Multiply**the product with electricity unit cost.**Divide**the product by 100.

### How do you calculate EV charging cost?

To calculate charging cost: Multiply the battery capacity with the electricity unit cost.

### How much does it cost to charge a Tesla?

To calculate the electricity cost for a trip in a Tesla:

**Multiply**the trip distance (X) with vehicle efficiency (E).**Multiply**the product with the charging cost per kWh (R).**Divide**the product by 100.

`E`_{C} = X × E × R / 100

### What is electric vehicle efficiency?

Electric vehicle efficiency is defined as the amount of **power consumed to travel 100 miles** or 100 km. The efficiency for a 2016 Tesla model S is `21.75 kWh/100 miles`

.

### Are Tesla charging stations free?

Unfortunately, Tesla no longer offers free charging. However, in the past there has been a scheme for new users to charge at no cost for a limited time.
