# 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 the 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.

We also have a similar tool for hybrid cars: The plug-in hybrid economy calculator! It can help you estimate the monthly costs of owning a partially-electric car.

## 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:

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:

where $E_{\text{C}}$ is the electricity cost for your trip.

A very similar approach can be used to estimate your general energy bills. Check the electricity cost calculator to learn more!

## 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:

$P = CR = 80 \cdot 0.15 = \$12$

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., $R = \$0.15\mathrm{/kWh}$.
- 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:

$E_{\text{C}} = \frac{XER}{100} = \frac{100 \cdot 160 \cdot 0.15}{100} = \$24.00$

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.
