The website and its home-screen version include Calculate, Compare, EV vs Fuel, your EVs and saved estimates. Charger search, favourites and Charger Alerts are features of the installed app. Download the Android app from Google Play for charger search and Alerts. The iOS app is coming soon. App access is set up automatically; no access code is needed.

EV Calculated is free to use, with no paid tiers or customer account needed for the calculator. You still pay the charging operator for electricity and any provider subscription you choose.

Open Compare → EV vs Fuel to compare electricity and petrol or diesel costs. Choose Charging options beside it to compare two ways to charge.

Open My EVs, or select the vehicle shown in a calculator, to add, edit or switch cars. Use Settings for units, currency, charging losses and comparison rates.

Where matching figures are available, we calculate driving efficiency as full-charge range divided by usable battery capacity. For example, 300 miles divided by 75 kWh gives 4 miles per kWh. These values are labelled as calculated planning estimates, not measured driving performance.

Some estimates use a standard-equipment reference, the lower end of an applicable published range band, or a provisional manufacturer figure. Their labels explain this and identify any equipment or source qualifications. Actual range varies with your car and driving conditions.

Where a source explicitly estimates usable battery capacity for the matching battery version, we may use it as a labelled starting estimate. This is shown separately from the calculated range estimate because battery capacity also affects charging energy, cost and time. You can replace it with your own figure.

Charging cost and time depend on battery capacity, charge levels, power, price and charging losses; they do not need driving efficiency. If a supported range is missing, you can still use those estimates. Range added, cost per mile and EV vs Fuel need a full-charge range or your observed driving efficiency. You can add either in My EV. Your own saved values are kept.

1. Select your EV and a charging option. Check the charger power and electricity price.
2. Enter your starting battery level. Choose By target charge and an ending level, or By charging time and a duration.
3. Review the estimated energy cost, time or battery reached, and range added.

In the Android app, you can use a supported charger price from the Map. You can also enter a price manually.

Enter the price for one kWh from your electricity supplier or charging provider. GBP electricity rates are entered and displayed in pence: for example, enter 7.5 for 7.5p/kWh or 79 for 79p/kWh. Presets are examples, not live quotes.

In Calculate and EV vs Fuel, use the minus and plus buttons to adjust the rate, or type directly into the box. GBP prices accept up to 1,000p/kWh in steps of 0.1p. Other currencies accept up to 10 per kWh, with up to three decimal places. Displayed GBP rates round to at most two decimal places in pence, with unnecessary trailing zeros omitted. Calculations retain the original rate.

Changing currency changes the label, not the value: there is no exchange-rate conversion. UK charger-price imports require GBP.

These are planning estimates. Your car’s charging limit, battery temperature and charge level, shared charger power and battery condition can change charging time. DC charging usually slows as the battery fills; peak kW is not sustained throughout a charge.

Cost depends on the actual supplied electricity, rate and fees. Range depends on your driving, weather and vehicle efficiency. Check your usable battery capacity and edit efficiency to match the miles or kilometres per kWh reported by your car. Published range is not guaranteed real-world range.

Not all electricity supplied by the charger reaches the battery: some powers the equipment and vehicle. We allow for that when estimating billed energy. For example, adding 18 kWh to the battery with 10% losses needs about 20 kWh from the supply.

Adjust the separate three-pin, wallbox/public AC and DC loss assumptions in Settings. Use driving efficiency from your car for range estimates, rather than bill-based consumption that already includes charging losses.

Charging estimates show energy cost only. Parking, connection, idle/overstay and other additional fees are excluded. A displayed provider subscription is not automatically divided between your charging sessions.

Check the selected provider’s price, payment eligibility and extra charges before you start. A charger may remain billable for parking or idle time after the battery is full; our estimate does not include that.

The calculator uses one selected energy rate throughout the estimate. It does not divide a session between cheap and standard-rate periods.

Networks can apply different rules. Osprey’s supported time-based options use the UK-local session start time; do not assume that rule applies to another network. Read the selected option’s timing conditions and confirm the provider’s terms before charging.

In Calculate and EV vs Fuel, Home offers a 3-pin plug or Wallbox. Public offers Destination, Rapid or Ultra-rapid, plus Find a public charger. Each tab has two example electricity rates. Home and Public remember separate electricity rates in Calculate and EV vs Fuel. The first example rates are 7.5p/kWh for Home and 54p/kWh for Public; enter your actual tariff or charger price. Switching tabs keeps your battery settings but resets the charger power to the chosen location’s default. In Calculate, charging-point power can be typed directly or adjusted by 0.1 kW for AC and 1 kW for DC with the minus and plus buttons. In Compare, enter charging-point power and electricity price directly. Your car’s charging limit is applied separately.

Drag a slider horizontally, or type into the charge-level and rate fields. On a touchscreen, vertical swipes scroll without changing the slider. On the battery graphic, drag near the boundary for the starting or ending level you want to change.

Charging time uses 15-minute steps. Dragging the ending battery level in time mode rounds the required time up, so the result may be slightly higher than the level you chose, but never above 100%.

Open Compare → Charging options. Select the EV, starting charge and either the same target charge or the same charging time. Set the power and electricity rate separately for Option A and Option B. In the installed app, each option can use a supported public charger price.

The results compare cost and time using those assumptions. View in Calculate transfers the chosen scenario and vehicle to Calculate. The comparison keeps its own inputs, so changing Calculate does not automatically change both comparison options.

Open Compare → EV vs Fuel. Enter the total distance for your trip, month or year, then the EV charging rate, fuel price and fuel economy. Efficiency is calculated automatically from the selected EV’s full-charge range and usable battery capacity, where those values are available. Check the charging losses. If range is unavailable, add your full-charge range or observed driving efficiency in My EV to use this comparison.

The period labels the distance you enter; it does not multiply it. For 10,000 miles a year, enter 10,000 and select Annual. UK MPG and US MPG use different gallons: choose the correct fuel-economy unit in Settings.

Using one public charger price assumes all modelled EV charging uses that rate. This compares electricity and fuel costs, not insurance, servicing, purchase price or total ownership cost.

Check the vehicle, battery levels or duration, charger power, electricity prices and loss assumptions in each view. Compare has independent inputs. EV vs Fuel also depends on entered distance and fuel economy.

The speed and cost rows beneath Calculate use that session’s energy and their own charging assumptions. Their example rates can be edited in Settings → Comparison settings.

1. Open Map and use your location, or search for a town, postcode or address. Location permission is optional when you search by address.
2. Move the map and choose Search this area when you want results for a different area. You can also use List.
3. Check the selected EV, connector and power filters, then open a location to choose a charging option.

We show participating networks where usable information is available, not every UK charger. A location can also be hidden by your area, connector or power filters.

1. Check your connection and any access or service message in the app. Search for the town/postcode again.
2. Try a wider area, lower power filter or Show all chargers / switch off connector matching. Check the selected EV.
3. Try List if the map will not load. If the location is still missing, check with the operator.

If the whole search keeps failing, contact us with the area searched, filters and the error shown. Reinstalling is not a useful first step.

In crowded areas we use smaller dots to keep the map readable. Zoom in or tap to see details. Locations at the same coordinates can share a marker: choose the location you need from the list.

A From price is a starting price across the eligible charging options. It is not a guaranteed price for every connector, payment method or vehicle. Open the location and check your selected option.

A matching connector and maximum charging speed are different things. Your vehicle must support the connection and charging type, and charging speed is limited by the vehicle as well as the charger.

Check or edit your vehicle’s connector profile when it is unknown. Show all chargers lets you inspect other options, but does not confirm compatibility. Peak DC power is not the average power for a full session.

Available means at least one of the shown options is reported available. In use means charging has been reported. Out of order means a fault has been reported. Availability unknown means we cannot confirm whether it is free. A charger reported working may still be occupied.

The summary covers the charging options shown by your filters. Different plugs with the same charger ID can be alternatives on the same machine; their number does not tell us how many cars can charge together or how many parking spaces are free.

Check the individual option and supplier check time. Reports can be delayed, and availability may change before you arrive. Refresh reads the information available to us; it cannot guarantee a new report from the operator.

Prices can vary by location, connector, payment method and time. Check that you have selected the same option in both apps. Supplier information can be older than the provider’s latest price; unsupported or stale prices may be unavailable for calculations. Opening an expired charger or connector, or returning to its screen, automatically checks our latest stored information. If the check fails, use Retry update or check with the provider. A flat price may remain visible for up to 24 hours as a dated, unconfirmed price; it cannot be used as a current calculation quote. Promotional deadlines and time-based prices still apply.

A published offer or advertised network minimum is not always a confirmed price for that location. Confirm the actual rate and fees with the operator before starting. If the same option still looks wrong, report the location, connector, payment method and time checked.

Choose the payment method you intend to use, such as contactless or the provider’s app. Check account/subscription eligibility and any time or location conditions. Different methods can have different prices.

Supplier prices and published provider offers may have different scopes. Follow the labels on the selected option rather than assuming a headline price applies everywhere. Provider subscription charges are separate from our energy estimate.

Open a location and choose a charging option. When only one matches, its prices open straight away. Check the plug, speed, payment method and any extra fees, then use Calculate cost. Subscription prices require the stated plan; ordinary app prices are shown separately.

Choose Calculate, Compare or EV vs Fuel as your destination. If you entered the finder from a calculator, the selected supported price returns there. Use the selected-charger return control to try another option; Use manual settings removes the charger selection.

Get directions opens an external maps service. Provider links open the operator’s service; match the physical charger reference or label there. EV Calculated does not start or stop charging sessions or take payment.

Check the model and variant, not just its registration year. If the right version is unavailable, add a car manually using its usable battery capacity, charging limits and connector details. Manufacturer specifications or your handbook can help.

You can edit a saved vehicle and enter its full-charge range to calculate efficiency automatically, or set driving efficiency from your own driving. To report a catalogue correction, include the model/variant, the value that looks wrong and a manufacturer source if you have one.

Open My EVs or the vehicle in your calculator. Choose Add another car, select a brand or search across all brands, then choose a model and version name. Choosing a brand shows its models directly beneath the dropdown and clears the search; searching clears the brand selection. Version names are listed alphabetically. Identical specifications from different source years appear as one choice. Where a name has different specifications, compare the battery, charging limits and fitted equipment. Years appear as identifiers only where their applicability has been reviewed; source listing years remain in the expandable data-source details. Registration year alone may not identify the correct specification. Charging options and software upgrades can also change an older car’s charging limit. Match your fitted equipment. Full model, version and specification lists are shown by default; scroll to find your car. Charging specifications are shown before selection; go Back without losing your place. Single-option steps are skipped. Check the summary and any provisional or missing values; use Edit details to change them before Save my EV. Manual entry is also available. Catalogue and specification background can be expanded below the relevant action button. Select a saved car to use it; use its Edit or Remove control to change it.

A removal can be undone briefly using Undo. Removing a car does not remove estimates already saved for it. Older saved estimates retain their own vehicle assumptions.

Favourite: a charger in your shared Map favourites and Alerts → My chargers list. Opening it fetches the location’s details when online. Its alert switch opens the choices for that charger.

Saved estimate: a snapshot of the vehicle, price and other assumptions you used. It is not automatically repriced.

Charger watch: a selected charger/price option monitored for supported updates in Alerts. Adding a favourite offers to set up alerts. Alerts are off until you save your choices; turning them off keeps the favourite.

No. A saved estimate keeps the price and assumptions you used when you saved it. Opening it does not check or replace that price.

For a new trip, reopen the charger details and deliberately use a current supported price to make a new estimate. The saved date or feed-check date describes that snapshot, not a fresh price check.

Use Watch this price on a charging option, or add a charger in Alerts → My chargers. Select one or more Connectors and Payment options, choose What to be notified about, then tap Create Alert. Existing choices use Save alert choices.

Phone notifications are optional: you can use the Updates Feed without enabling them. Turn alerts off keeps the favourite and Near home reference. Removing a favourite removes its alerts and turns off Near home if it is the reference. Saved estimates are unchanged.

1. Open Alerts → Updates Feed to see whether the event arrived in the app.
2. Open Settings → Charger Alerts notifications. Check notifications are enabled, then check EV Calculated’s notification permission in your phone settings.
3. Check quiet hours, your connection and the app version. Quiet hours are off by default and use device time. Use the main Save settings button at the bottom to save your notification choices.

Reports and delivery can be delayed, and not every report produces a fresh push. Reports received during quiet hours stay in Updates without a device notification. If it persists, tell us the event time and whether it appears in the feed.

After enabling notifications, use Send a test notification in Settings → Charger Alerts notifications. Give it a few minutes, then check both Updates and the phone’s notification area.

Tests are limited to prevent repeated sends. If you reach the allowance, wait for it to reset instead of retrying. Clearing Updates does not reset the allowance. A test entry in Updates does not by itself prove the phone displayed a notification. Include its time if you contact support.

Add a charger to your favourites on the map first. In Near home, use your current location, pick a map point or search an address. The next step appears after you choose a location: pick a favourite charger, then choose whether matches must be the same price or cheaper and the same speed or faster. Save the near-home watch. Selecting a point alone does not activate it. Your movements are not tracked.

Near home looks for newly added chargers closer to that point, within 31 miles (50 km), with compatible connections and your selected price/speed preferences. It compares the cheapest published energy price when no payment choice is saved. Unconfirmed payment labels and extra fees do not exclude chargers. Different tariff periods and fees still apply; check the details before travelling. New matches use at most one daily push.

It is not a continuous search for every existing cheaper charger. No matches can be normal; check the reference and any Needs attention message.

Opening Updates Feed clears the navigation badge. Recent entries can still be marked New this visit. Removing an update is separate from stopping its charger watch.

To remove watches, the home point and update history from our service, use Settings → Charger Alerts notifications → Delete alert setup while online. Cars and saved estimates remain. Uninstalling alone does not immediately delete server-side setup.

Updates are retained for 90 days; setup is removed after 180 days without an app refresh. Watches have no cross-device recovery. See the Privacy policy for more about optional Alerts processing.

Check your connection when using online features. Close and reopen EV Calculated and follow the update instructions for your version. If a map fails, try List or address search.

Do not clear storage or uninstall as a first step. That can remove your saved information. If the problem continues, send the exact steps, error text, time and app/browser version. Remove personal information from screenshots.

Contact the charging operator using the details on the charger or in its app. They can help with starting/stopping a session, charger faults, a stuck cable and payment or refund questions.

EV Calculated cannot control the charger or issue charging refunds. If our displayed information or calculations look wrong, report that to us with the location and selected option.
