EV Charging Cost Calculator Pakistan

Calculate EV charging cost including energy loss

All defaults are worked-example inputs, not live prices or verified vehicle quotations. Replace them with your own measurements and rates. Calculations run in your browser; no account is needed.

Battery use and billed electricity differ

Vehicle efficiency often describes battery energy per 100 km. Some billed electricity is lost during charging. Here loss means the fraction of wall energy that does not reach the battery: billed kWh = battery kWh divided by (1 − loss/100). If your measured consumption already includes wall energy, set loss to zero to avoid counting it twice.

Worked 100 km example

At 15 kWh/100 km, a 100 km trip uses 15 kWh in the battery. Assuming 10% charging loss gives 16.67 billed kWh. An illustrative PKR 60/kWh rate gives PKR 1,000, or PKR 10/km. Loss and tariff are editable assumptions, not a promise about your charger or current electricity bill.

Choose the tariff you actually pay

Home bills and public chargers can include taxes, fixed charges, time-of-use rates or session fees. Enter an effective incremental price per kWh for this estimate and add unrelated fixed or session charges separately. Battery size alone does not establish cost per kilometre; use consumption over your route. This calculation does not predict range, charging speed or battery health.

Calculation method: MyDriveCost distance-and-consumption arithmetic. Examples are illustrative. Check your own receipts, measured usage and applicable reimbursement rules.

Build a charging budget from your routine

Start with where the car will normally be parked when it needs charging. Separate home, workplace and public sessions. A low home tariff is not a useful assumption for journeys where you will actually depend on a public charger.

What to record from each charging session

• Date and charging location.
• Electricity delivered or billed in kWh, with the measurement source identified.
• Total amount paid and any separately listed parking, session or idle fees.
• Starting and ending battery percentage, if available, for context rather than as a substitute for billed kWh.

Keep receipts or charger statements. A car's dashboard energy figure and a charger receipt measure different parts of the process; do not assume their difference is entirely a billing error.

Use a home-and-public charging mix

For a purely illustrative month with 200 billed kWh, suppose 150 kWh costs PKR 60 each at home and 50 kWh costs PKR 100 each publicly. Energy costs total PKR 14,000, giving a blended rate of PKR 70/kWh. The simple average of the two rates, PKR 80, would be inappropriate because the energy quantities differ. These are invented planning rates, not current Pakistan tariffs.

Enter the blended rate only when it represents your planned mix. Add session and parking charges separately. If you derive a rate from a household bill, distinguish existing household costs from the extra costs attributable to charging; a bill-wide average is not necessarily the cost of the next kWh.

Separate setup spending from everyday charging

Keep charger purchase, installation, any approved electrical work and parking arrangements in a separate upfront budget. Obtain an installation assessment and quote from a qualified provider. This calculator estimates energy spending; it does not establish whether a socket, circuit or installation is suitable.

Review a month that differs from the estimate

First compare actual distance and charging locations with the plan. Then check the billed kWh, tariff and extra fees. More public charging can raise spending even when the car's consumption has not changed. Compare periods with similar starting and ending battery levels before drawing conclusions from short records.
