Monthly Cost to Charge an EV in Indonesia
The cost of a single charge is easy to picture, but the more important question for a prospective electric vehicle (battery electric vehicle, or BEV) owner in Indonesia is usually this: how much will my monthly electricity bill go up? This guide answers it from a monthly running-cost view rather than a per-charge view. You will learn how to estimate the monthly charging cost from your driving distance and the PLN electricity tariff, why it lands far below petrol, and how to check the estimate for your own driving pattern. Every tariff on this page is taken from an official, dated source.

How much does an EV add to your monthly bill?
The monthly bill from an EV depends on three things: how far you drive in a month, how efficient the car is (its energy use per kilometre), and the electricity rate per kWh you pay. For daily charging at home, the relevant rate is the PLN residential tariff. That tariff, not the higher SPKLU rate, is what sets your routine cost, because most everyday charging is best done at home by plugging in overnight.
The simplest way to estimate it is to think about energy first, then cost. First work out the monthly energy: divide your monthly driving distance by the car's efficiency. Then multiply that monthly energy by the electricity rate per kWh to get the monthly cost. The next section sets out the symbolic formula, and the rate tables further down this page show the current PLN tariff figure with its source and date, so you do not have to guess.
The monthly cost formula
- Energy needed
- energy (kWh) = battery capacity × (target % − current %) ÷ 100
- Charging time
- time (hours) = energy ÷ charger power (kW)
- Cost
- cost = energy × electricity rate per kWh

A worked example for an everyday driver
Picture a common driving pattern: say 1,000 to 1,500 km per month, a typical distance for a city-based driver. A common mid-size EV uses roughly 15 to 18 kWh for every 100 km in real-world use. From those two figures alone you can already estimate the monthly energy: the further you drive, the more energy you use, and the monthly cost scales up in proportion. You then multiply that monthly energy by the PLN residential rate per kWh to get the added bill.
This guide deliberately does not print a rupiah total, because your distance, the car's efficiency, and your exact tariff all change the answer. The point to take away is the pattern: the monthly cost rises and falls with distance and tariff, not at random. The rate tables and the calculator on this site provide the precise figures, worked out from your own inputs rather than from a single fixed example.
| Scenario | Energy | Time | Cost |
|---|---|---|---|
| At home (AC) 20% → 80% | 18 kWh | 2 hours 44 minutes | Rp 30.673,12 |
| Public DC 20% → 80% | 18 kWh | 36 minutes | Rp 44.506,37 |
Per kilometre: EV versus petrol
The fairest way to compare running cost is per kilometre. For an EV, the cost per km is the energy per km multiplied by the electricity rate per kWh. For a petrol car, the cost per km is the fuel use per km multiplied by the petrol price per litre. In Indonesia, using the PLN residential tariff on the electric side and the Pertamax (RON92) pump price on the petrol side, the per-km cost of an EV sits well below the per-km cost of a comparable petrol car. That is the main reason the monthly electricity bill, even though it goes up, stays far lighter than the fuel money it replaces.
It is this per-km gap that compounds into monthly and yearly savings. The more you drive, the larger the cumulative saving versus petrol, because every kilometre on electricity is cheaper. One caveat: if you frequently rely on public SPKLU DC charging instead of charging at home, your per-km electricity cost rises because the DC rate per kWh is higher, so part of the saving shrinks. That is why the most economical habit is still to make home your primary charging source.

Calculate it for your own car
The most accurate way to estimate your monthly cost is to use the calculator on this site. Its running-cost projection accounts for your monthly driving distance and shows an estimated monthly and yearly cost, alongside the saving versus petrol. Pick your car, enter your monthly distance, and let the calculator do the arithmetic; the result is far more relevant than any fixed example in a guide.
Want to go deeper? The "Home charging vs public SPKLU cost" guide compares the cost of a single charging session at home versus at an SPKLU, while the "How charging cost is calculated" guide sets out the full formula and the official electricity-tariff sources it uses. This page complements both by answering the monthly question: how much an EV adds to your electricity bill in Indonesia.
Frequently asked questions
How much does an EV add to your monthly electricity bill in Indonesia?
- It depends on your monthly driving distance, the car's efficiency, and your electricity rate. To estimate it: divide your monthly distance by the car's efficiency to get the monthly energy (kWh), then multiply by the PLN residential rate per kWh. For a common pattern of around 1,000 to 1,500 km per month in a mid-size EV, the added bill is far lighter than the petrol money it replaces in Indonesia. Use the calculator on the home page for a precise figure tailored to your car and tariff rather than a single fixed example.
How do you calculate the monthly cost of charging an EV?
- Use two steps. First, the monthly energy (kWh) equals your monthly distance divided by the car's efficiency (kWh per 100 km). Second, the monthly cost equals that monthly energy multiplied by the electricity rate per kWh. For routine charging at home, use the PLN residential tariff, which is shown with its date in the sources table on this page. The calculator on this site runs the same arithmetic for your specific car and distance.
Is the monthly cost of an EV cheaper than petrol?
- Yes. Compared per kilometre, the electricity cost of an EV sits well below the petrol cost of a comparable car, using the PLN residential tariff on the electric side and the Pertamax (RON92) price on the petrol side. That per-km gap compounds into monthly and yearly savings: the further you drive, the larger the saving. Frequently using public SPKLU DC charging reduces part of the gap because the DC rate per kWh is higher, so charging at home stays the most economical.
Which electricity rate applies to monthly charging cost?
- For daily charging at home, the relevant rate is the PLN residential tariff, not the higher public SPKLU DC rate. Most routine charging is best done at home by plugging in overnight, so the residential tariff is what drives your monthly bill. The exact rate, with its source and date, is in the rate table on this page and is updated when the official PLN value changes.
Does driving further raise the monthly cost a lot?
- The monthly cost rises in proportion to distance: twice the distance means roughly twice the energy and twice the cost, at the same efficiency and tariff. But because an EV's per-km cost is far below petrol, driving further actually widens the cumulative saving versus a petrol car. To see the figures for your own distance, enter your monthly distance in this site's calculator and read its projected monthly and yearly cost.
