Electric car charging cost calculator
Work out what a full charge costs, the cost per kilometre, the realistic range and how much you save against petrol.
How to use
- Enter the battery size and the car's consumption in kWh per 100 km — the trip computer's average is more accurate than the brochure.
- Set your electricity tariff and the power of the charger you actually use (a home wallbox is typically 3.5 or 7 kW).
- Fill in the petrol price and your old car's km/litre to see the cost per kilometre side by side and the saving per 100 km.
Frequently asked questions
Which electricity tariff should I enter?
The one on your own PLN bill: household rates differ by connected load, and public SPKLU charging is billed at its own, higher rate per kWh. If you charge overnight at home, check whether your account qualifies for PLN's off-peak EV rate — enter that figure instead.
Why is my real-world range shorter than the number here?
Because range is simply battery ÷ consumption, and consumption is not constant. Highway speed, air conditioning, a full car, hills and rain all push it up. Enter a higher kWh/100 km figure to model a worst case.
Does the charging time include DC fast charging?
No. The time shown is battery capacity ÷ charger power, which matches AC home charging closely. DC fast charging slows down sharply above roughly 80%, and every method loses a little energy as heat, so real sessions run somewhat longer than the ideal figure.
Why does a token give fewer kWh than its value divided by the tariff?
Because not all of the token becomes electricity. The street-lighting tax (PPJ) is taken out first at the rate your region sets — 2.4 per cent in Jakarta, up to 10 per cent elsewhere — and only the remainder is converted at the per-kWh tariff, with PPN on top for connections above 6,600 VA. The seller's admin fee of Rp 1,750–5,000 is separate again, and charged per purchase rather than per kWh. Put the gap you actually experience in this field: divide a token's value by the kWh it credited and compare that with the base tariff. A real example: Rp 100,000 on a 7,700 VA connection crediting 50.3 kWh works out at Rp 1,988 per kWh, 17 per cent above the 1,699.53 tariff — which is what this field defaults to. That is PPJ of 6 per cent plus the 11 per cent PPN that applies above 6,600 VA.
About this tool
Running an electric car in Indonesia is mostly a question of two numbers: your PLN tariff per kWh and how many kWh the car actually uses per 100 km. Put those in and this calculator turns them into the figures that matter — what a 0–100% charge adds to your electricity bill, what each kilometre costs, how far the pack should take you, and how long a home AC charger needs to fill it. It then sets that against petrol: enter the pump price and your old car's km/litre and you get the cost per kilometre for both, plus the rupiah you keep every 100 km. Manufacturer range claims come from lab cycles, so the honest way to use this is to enter the consumption from your own trip computer after a few weeks of driving. One line is worth explaining: the petrol equivalent tells you how far the money for a single litre of petrol takes you on electricity, so you can read it straight against the km/litre of the car you drive now.
