Tesla charging cost per month

# Tesla charging cost per month: see the total and what drove it

A useful monthly total brings home charging, Supercharging and other public charging together — while keeping the kWh, tariff and individual sessions behind the number visible.


<!-- AEO-UK-BEGIN -->
## Quick answer

Monthly Tesla charging cost is the sum of the charging sessions in that period, not simply battery capacity multiplied by one electricity rate. Home tariffs, public charging and Supercharging can have different prices, and dynamic home tariffs can vary by time.

DriveQuery is designed to keep the session-level evidence behind the monthly number.

## Questions this page answers

- How much does Tesla charging cost per month?
- How can I separate home and public charging cost?
- Does a dynamic tariff change the monthly charging-cost calculation?
- Can Tesla charging costs be tracked automatically from session history?

## What a useful monthly charging-cost view should show

![Tesla monthly charging cost and session history in DriveQuery](https://drivequery.com/assets/charging-history.webp)

**Monthly Tesla charging cost with the sessions behind the total**

### One monthly total

Bring home, Supercharging and other paid charging into one period instead of checking several places.

### Energy and cost together

A cost without kWh is hard to verify. Keep both visible so you can see what changed month to month.

### Split by charging source

Separate home, work, Supercharger and other public charging so one expensive road trip does not distort your home-charging picture.

### Keep the price basis

Show whether a session used an off-peak tariff, a flat rate, a public-network invoice or another price assumption.

## Quick answer: add the cost of each charging source, not just the kWh

Your Tesla charging cost per month is the sum of what you paid to charge at home, at Superchargers and at other paid charging locations during that month. The simple version is:

**Monthly charging cost = home charging cost + Supercharging cost + other public/work charging cost.**
For the best result, calculate each charging session using the price that actually applied to that session instead of multiplying all monthly kWh by one average rate.

That distinction matters because the same Tesla can be charged at £0.08/kWh overnight at home, at a much higher daytime home tariff, at a Supercharger with time-dependent pricing and at a third-party public charger with its own tariff or session fee. One blended rate can hide where the money went.

Tesla's own [Charge Stats](https://www.tesla.com/support/tesla-app/charge-stats) already gives owners a useful view of energy charged and estimated spending. Tesla lets you switch the graph between *Total Charged* and *Total Spent*, set custom Home, Work and Other rates, and model time-of-use periods. DriveQuery's goal is not to pretend that this does not exist. The useful extra layer is keeping a month tied to the individual charging sessions and price assumptions that produced it.

## How to calculate Tesla charging cost per month

If every charge happened at one flat electricity rate, the calculation is easy:

**Monthly cost = energy charged (kWh) × price per kWh.**
Example: 250 kWh × £0.25/kWh = £62.50.

Real months are usually more complicated. A better calculation works session by session:

1. **Record the energy for each charge.** Keep the kWh associated with the session or billing record.
2. **Identify where it happened.** Home, work, Tesla Supercharger or another public network can all have different pricing.
3. **Apply the right price.** For home charging, that might depend on time of day. For paid public charging, use the actual session price or invoice when available.
4. **Add any session-specific fees.** Public charging can include fees that are not explained by kWh alone.
5. **Sum the sessions for the month.** Keep the underlying entries so the total remains auditable.

## A worked monthly example

Imagine a Tesla driver with a cheap overnight home tariff, a small amount of peak-rate home charging and two types of public charging. The figures below are illustrative — they are not current market prices.

| Charging source | Energy / basis | Example cost |
| --- | --- | --- |
| Home — off-peak | 210 kWh × £0.08 | £16.80 |
| Home — peak | 18 kWh × £0.32 | £5.76 |
| Tesla Supercharging | Final session/invoice totals | £28.40 |
| Other public charging | Provider session totals | £14.20 |
| **Month** | **228 kWh home + paid public charging** | **£65.16** |

The interesting part is not only the £65.16. You can also see that most energy was charged cheaply at home, while a relatively small amount of public charging made up a large share of the bill. That is the kind of pattern a monthly total should reveal.

## Home charging: the tariff matters as much as the kWh

Home charging is often where a monthly estimate becomes misleading. If your electricity contract has one flat price, multiplying kWh by that price may be enough for a practical estimate. With a time-of-use or dynamic tariff, **when the car charged** matters.

Tesla's Charge Stats supports time-of-use home rates and can show how much Home charging energy falls into off-peak, mid-peak and peak periods. That is a useful reminder that 200 kWh charged at night is not economically equivalent to the same 200 kWh charged during an expensive period.

### Flat tariff

Use the applicable all-in per-kWh rate if it genuinely represents what another kWh of charging costs you.

### Time-of-use tariff

Split charging by tariff period. Do not price every session at the month's cheapest rate simply because most charging happened overnight.

### Dynamic tariff

The relevant price can change every hour or quarter-hour depending on the market and contract. Session timing becomes part of the cost calculation.

### Solar / home battery

“Free solar” can be useful shorthand, but the economic cost may depend on export value, battery cycling and your own accounting method. Keep the assumption explicit.

If you want to reduce this part of the bill rather than merely report it, see the [Tesla smart charging guide](https://drivequery.com/en/smart-charging/) and [dynamic-tariff charging app guide](https://drivequery.com/en/tesla-dynamic-tariff-charging-app/).

## Tesla Charge Stats already estimates spending — so what is missing?

Tesla's Charge Stats is a strong starting point. Tesla says the charging graph can show total energy or estimated spend for a selected period, with charging grouped by location type. It also lets you define Home, Work and Other prices. There are, however, several reasons why you may still want a separate monthly cost record:

- **It is an estimate where the price is an estimate.** Tesla says Work and Other charging can default to an estimated regional electricity price until you customise the rate.
- **Same-day sessions are aggregated by location type.** Tesla states that Charge Stats adds up charging that occurred for each type of charging location by day. That is useful for graphs but different from a session-by-session ledger.
- **Public charging may have a final invoice.** Where a provider gives you a real billed amount, that is stronger evidence than recalculating the session from a generic rate.
- **A month can mix sources.** A monthly cost tracker is easier to audit when the home estimate, Tesla invoices and third-party charging are clearly separated.

DriveQuery is being designed around that traceability: a monthly number that can be opened back up into the charging events, energy and price basis behind it.

## Supercharging: use the final charge, not a guessed average

Tesla publishes Supercharger pricing by site and, in supported markets, by time period. Tesla also says the price for a session is determined by the plug-in time and does not change mid-session if the displayed price changes.

For monthly reporting, the cleanest approach is to use the actual Supercharging transaction or invoice rather than multiplying Supercharger kWh by a generic “average Supercharger rate”. Tesla lets owners view charging history and download Supercharging invoices from the app.

Also keep non-energy fees separate when they occur. Tesla's current support material describes congestion fees at busy sites. A cost tracker that only stores *kWh × rate* can miss fees that were actually billed.

## Other public chargers are the hardest category to estimate

Third-party charging networks can bill by kWh, time, connection, membership plan or a combination. Some networks show the final charge immediately; others settle it later. If you have a receipt or invoice, use the billed amount. If you only have vehicle energy data, label the result as an estimate.

| Data source | Good for | Main limitation |
| --- | --- | --- |
| Energy × known tariff | Home charging and simple public tariffs | Can miss fixed/session fees and charging losses |
| Tesla Charge Stats | Fast overview of energy and estimated spend | Some location costs depend on configured or estimated rates |
| Supercharger invoice | Final Tesla Supercharging cost | Covers only those billed Tesla sessions |
| Third-party receipt/invoice | Final public charging cost | May live in a separate provider app or account |
| DriveQuery session history | One timeline tying vehicle charging events to monthly reporting | Not a substitute for an electricity or charging-provider invoice |

## Why the kWh in your car may not match the kWh on your electricity bill

One of the easiest mistakes in EV cost calculations is assuming that every kWh drawn from the wall becomes one kWh stored in the battery. Charging has conversion losses and the car can use energy for battery conditioning and other systems while connected.

That means two valid measurements can describe different points in the system:

- **Vehicle energy added** is useful for understanding what reached the car/battery.
- **Wall or meter energy** is closer to what the household electricity supplier actually billed.

If you need invoice-level home charging reimbursement, a certified charger or electricity meter may be the correct source depending on the employer, country and policy. If you want a practical ownership-cost view, vehicle charging data can still be very useful — just make the measurement basis clear.

**Do not hide the measurement point.** A precise-looking monthly figure built from battery-side kWh is still an estimate of grid cost if charging losses are not included.

## Monthly charging cost vs. monthly driving cost

Charging cost tells you what you spent putting energy into the car. It is not the same as the cost of driving a mile or kilometre. To understand the latter, pair charging cost with distance driven during the same period.

For example, if charging cost £65.16 and the car travelled 900 miles during that period, the charging-energy cost is about 7.2 pence per mile. That still excludes insurance, tyres, depreciation, finance, servicing and other ownership costs.

Matching the same month of [Tesla trip history](https://drivequery.com/en/tesla-trip-history/) with charging history is more meaningful than comparing a charging month with an unrelated odometer total.

## What a useful monthly charging-cost dashboard should show

- **Total charging energy** for the selected month.
- **Estimated or billed total cost**, clearly labelled.
- **Home / work / Supercharger / other split**.
- **Average cost per kWh** for the whole month and, ideally, by charging source.
- **Individual sessions** behind the total.
- **Price basis** for each estimated session.
- **Fees** when they are known and separate from energy.
- **Month-on-month comparison** so you can see whether cost changed because you drove more, charged somewhere more expensive or used a different tariff period.

This is the idea behind the [DriveQuery Tesla charging cost tracker](https://drivequery.com/en/tesla-charging-cost-tracker/): keep the monthly headline simple, but never make the underlying sessions disappear.

## How to diagnose a surprisingly high Tesla charging month

1. **Check total kWh first.** If energy jumped, you may simply have driven or charged more.
2. **Check the charging-location split.** A road trip can move a large share of energy from home to faster but more expensive public charging.
3. **Check tariff timing.** More peak-period home charging can raise cost without changing total kWh much.
4. **Check public-session fees.** Look at invoices rather than estimating from kWh alone.
5. **Check whether the rate assumptions changed.** An updated home, work or other-location price can alter an estimate even if charging behaviour did not change.
6. **Check the measurement basis.** Wall energy and vehicle energy can differ.

A good dashboard should make these checks possible without exporting a spreadsheet first.

## Frequently asked questions about Tesla charging cost per month

Does the Tesla app show monthly charging cost?

Tesla Charge Stats can show charging energy and estimated spending over a selected period. The accuracy of the spending view depends on the prices configured for Home, Work and Other charging, while Tesla Supercharging has its own transaction and invoice history.

What is the easiest way to calculate my Tesla charging cost for a month?

Add the cost of each charging source for the month. For flat-rate home charging, kWh multiplied by the applicable per-kWh rate may be enough. For time-of-use tariffs and paid public charging, use the rate or final charge that applied to each session.

Why is my electricity bill higher than the Tesla charging estimate?

The household bill includes all household electricity, not just the car. Even when isolating the EV, wall energy can exceed vehicle energy because charging has losses and the vehicle may consume energy while connected. Tariff standing charges or other bill components can also be outside a vehicle-side estimate.

Should I include charging losses in the monthly cost?

If you are calculating what the electricity supplier billed for home charging, wall-side energy is the better basis because it includes charging losses. If only vehicle-side energy is available, keep the result labelled as an estimate.

How should I calculate cost on a time-of-use tariff?

Split the home-charging energy by the tariff periods in which it was charged and apply the corresponding prices. Tesla Charge Stats itself supports off-peak, mid-peak and peak periods for Home charging.

Should I calculate Supercharging from kWh?

Use the final Tesla transaction or invoice when available. Tesla pricing can vary by site and time, and additional fees can apply, so the billed amount is stronger than a generic per-kWh assumption.

Can DriveQuery replace my electricity or charging-provider invoice?

No. DriveQuery is intended to organise vehicle charging events and cost context. Where you need accounting, reimbursement or tax evidence, keep the relevant electricity bill, certified meter data or charging-provider invoice required by your policy or jurisdiction.

What is more useful: monthly cost or average cost per kWh?

Use both. Monthly cost tells you the cash impact. Average cost per kWh helps explain whether the change came from higher prices or simply more charging. The location split and individual sessions tell you why that average moved.
