# How to Estimate the Charging Cost of an EV Road Trip

Multiply trip miles by your car's kWh per 100 miles, then split the energy between what you charge at home before leaving and what you buy on the road. For a 500-mile trip, a typical 33.5 kWh/100 mi EV needs about 167.5 kWh: **$30.42** if it were all home power at 18.16¢/kWh, or **$75.38** if it were all fast charging at an example $0.45/kWh.

By [EV Charge Cost Editorial Team](https://evchargecosts.com/about/). Published September 28, 2026, updated October 26, 2026.

## Step 1: total energy for the trip

Trip energy (kWh) = miles × kWh per 100 miles ÷ 100. The EPA rating includes charging losses, so this is energy as billed. For 500 miles in a typical 33.5 kWh/100 mi EV, that is 167.5 kWh.

Highway driving often uses more than the EPA combined rating, and cold weather adds more. As an illustration, if your car uses 15% more on the highway, the trip needs 192.6 kWh. Scale any cost below by the same factor. See [highway speed and EV efficiency](https://evchargecosts.com/guides/highway-speed-and-ev-efficiency/).

## Step 2: how much comes from home

Leave with a full battery charged at home and the first leg runs on your cheapest energy. In the estimate below, we assume you start at 100% and arrive at a charger with an illustrative 10% buffer, so the home-charged miles are 90% of the EPA range. Everything after that is fast charged.

## Step 3: price the fast-charged miles

Multiply the remaining energy by the public price. We use an example price of $0.45/kWh; replace it with the price at the stations on your route, which varies by network, location and time. If a station bills per minute, your effective price depends on how fast your car charges; see [the DC fast charging curve](https://evchargecosts.com/guides/dc-fast-charging-curve-explained/).

## Worked example: 500 miles, one way

The table applies the method to popular models using EPA range and efficiency for each model's representative trim, home power at the U.S. average price (18.16¢/kWh) and the example public price. Stops assume each fast-charging session adds 70% of the EPA range (roughly 10% to 80%), an illustration.

**500-mile trip: home-charged start plus fast charging at an example $0.45/kWh**

| Model | Trip kWh | Home miles | Fast miles | Home cost | Fast cost | Total | Stops |
| --- | --- | --- | --- | --- | --- | --- | --- |
| [Tesla Model 3](https://evchargecosts.com/vehicles/tesla-model-3/) | 131.9 | 311 | 189 | $14.92 | $22.39 | **$37.30** | 1 |
| [Tesla Model Y](https://evchargecosts.com/vehicles/tesla-model-y/) | 134.3 | 303 | 197 | $14.80 | $23.78 | **$38.57** | 1 |
| [Chevrolet Equinox EV](https://evchargecosts.com/vehicles/chevrolet-equinox-ev/) | 163.1 | 276 | 224 | $16.37 | $32.83 | **$49.20** | 2 |
| [Hyundai Ioniq 5](https://evchargecosts.com/vehicles/hyundai-ioniq-5/) | 172.5 | 242 | 258 | $15.17 | $40.04 | **$55.20** | 2 |
| [Ford F-150 Lightning](https://evchargecosts.com/vehicles/ford-f-150-lightning/) | 239.6 | 288 | 212 | $25.06 | $45.71 | **$70.77** | 1 |

For comparison, a 30 mpg gas car would use about 16.7 gallons for the same trip, or $71.40 at the U.S. average of $4.284 a gallon (EIA, week of 2026-10-19). In this example, Tesla Model 3 would spend $37.30, $34.10 less than the gas car.

## What moves the total most

- **The public price.** Fast-charged miles cost 2.5 times as much as home-charged miles at the example price and the U.S. average rate. A cheaper network or a membership plan changes the total more than anything else.

- **Destination charging.** A Level 2 charger at your hotel or a relative's home turns fast-charged miles for the return leg into cheaper overnight miles. If the host bills you, the cost is their electricity rate; the [state price pages](https://evchargecosts.com/states/) show what that is likely to be.

- **Round trips.** The return leg usually starts without a home charge, so its fast-charged share is larger unless you charge at the destination.

- **Your home state's price.** The same home-charged start costs more in [Hawaii](https://evchargecosts.com/states/hawaii/) (47.18¢/kWh) than in [Nevada](https://evchargecosts.com/states/nevada/) (12.72¢/kWh).

## Adjusting the estimate for your trip

To adapt the table, change one input at a time. For a longer trip, only the fast-charged miles grow, because the home-charged start is fixed by your range. For a shorter trip that fits within one charge, the whole cost is home power: a trip of 100 miles costs a typical EV about $6.08 at 18.16¢/kWh. If you expect heavier highway use, multiply every cost by your consumption factor, such as 1.15 in the 15% illustration above.

## A quick checklist before you go

- Charge to 100% at home, timed to finish close to departure.

- Check the plug type and payment method at each planned stop; see [NACS vs CCS vs J1772](https://evchargecosts.com/guides/nacs-vs-ccs-vs-j1772/).

- Plan to arrive low and leave around 80% at fast chargers.

- Look for lodging with Level 2 charging.

- Budget with a margin for highway speed and weather.

## Questions people ask

### How much does a 500-mile road trip cost in an EV?

It depends on the car and the charging mix. A typical 33.5 kWh/100 mi EV needs about 167.5 kWh, which costs $30.42 at the U.S. average home price or $75.38 at an example $0.45/kWh fast-charging price.

### Is an EV road trip cheaper than driving a gas car?

Often, but not always. Heavy fast charging narrows the gap; a 30 mpg gas car costs about $71.40 for 500 miles at the current U.S. average gas price.
