EV charging rates in Singapore: home tariff against public chargers

It depends on where you plug in. At home, you pay your electricity tariff. At a public charger, you pay whatever the charger's operator sets, and at the median that is 2.1 to 2.4 times as much per kWh. Energy is sold in kilowatt-hours (kWh): a charger delivering 10kW for one hour supplies 10kWh.

If you buy electricity from SP Group, you pay the regulated household tariff. For 1 October to 31 December 2026 it is 31.16 cents per kWh including GST, or 28.59 cents before GST. SP Group is the default supplier, so no action is needed to be on this tariff. It is reviewed every quarter, and SP publishes the current rate on its tariff information page.

You can instead buy electricity from a retailer on the Open Electricity Market. Switching is optional and there is no deadline; what you pay then depends on the retailer's package, so use the rate on your own bill.

At the SP tariff, putting 60kWh into a car costs about $18.70. Most charges top up part of the battery, not all of it, so a typical night's charge costs less. A little energy is lost as heat while charging, so your meter reads slightly more than the battery takes in.

Who can charge at home depends on where you live. A landed home can have its own charger on its own supply: see what a landed home installation involves. In a condo, chargers in the common areas are shared and the MCST sets the rate, so you pay that rate rather than your home tariff; see condo charging. In HDB carparks, chargers are deployed and operated by LTA-appointed operators. Our guide to charging at HDB, condo and landed homes covers each in full.

The most recent official figure is from the Ministry of Transport. In a written reply to Parliament on 22 September 2025, it put the median charging price at $0.66/kWh in HDB carparks and $0.74/kWh in private commercial carparks. A median is the middle price: half of chargers cost less, half cost more.

Prices vary by operator, by location and by the charger's power rating. They are commercial decisions: the operators set them, not the Government. Operators do not publish a single rate card. Each charger's price is shown in the operator's app, and that is the figure to trust.

1. 1

   Check the rate in the app

   Look at the price for the charger you are at, before you start. SP Mobility's terms, for example, charge the rate that applies at the start of the session for each kWh you use.

2. 2

   Check for an idle fee

   LTA notes that some operators charge an idle fee for staying in the lot after the session is complete. SP Mobility's terms, for example, charge by the minute once a grace period has passed, at chargers where the feature is enabled; the app shows the fee and the grace period.

3. 3

   Check the parking

   The charging price covers the electricity. Check whether the car park also charges for parking while you are there.

Yes, by a wide margin on today's figures. At 31.16 cents, a kWh at home costs about 47% of the HDB median and 42% of the private commercial median.

The installation is the part we price, after a free site survey; our guide to what drives installation cost explains each factor. If you have solar panels, charging from your own roof is covered in our solar EV charging guide.

Two numbers do it: how much energy your car uses, and what you pay for it.

1. 1

   Find your car's energy use

   In kWh per 100km, from the trip computer or the manufacturer's figure. Your own driving gives the truest number.

2. 2

   Multiply by your rate

   kWh per 100km × your price per kWh = your cost per 100km. Use the tariff on your bill at home, or the price in the operator's app in public.

3. 3

   For one charge

   Battery size in kWh × the share you are adding × your price per kWh. Adding 20% to 80% of a 60kWh battery is 36kWh.
