Open Electricity Market retailer plans are not modelled — this is the SP regulated tariff. Water uses PUB domestic rates from 1 April 2025. Sanitary fittings fees no longer appear as a separate line on most bills. Not a substitute for your SP invoice.
关于这个新加坡水电费估算器
SP Group issues a combined utilities bill for most households: electricity at the Energy Market Authority’s regulated tariff (unless you switched to an Open Electricity Market retailer) and water on PUB’s behalf.
The household electricity tariff for 1 October to 31 December 2026 is 28.59 cents per kWh before GST (about 31.16 cents with 9% GST), down from 31.91 cents in Q3. A 400 kWh month is about $114.36 before GST for electricity alone at the Q4 rate.
PUB’s domestic water price from 1 April 2025 (unchanged in 2026) has three parts on each cubic metre: potable tariff ($1.43 for the first 40 m³, $1.81 above), Water Conservation Tax (50% / 65% of tariff), and a waterborne fee of $1.09. Twenty cubic metres therefore cost about $64.70 before GST.
GST at 9% applies to both. Eligible HDB flats receive a GST Voucher – U-Save credit that this page can subtract if you type it. Retailer discounts, gas, and refuse fees are omitted.
Not a bill and not SP/PUB advice. Tariffs change every quarter (electricity) or when PUB announces. Verified 30 Sep 2026.

关键术语与概念
Regulated tariff is EMA’s quarterly SP rate for households who have not switched retailer.
WCT is a tax on potable water that steps up above 40 m³.
Waterborne fee pays for used-water treatment.
U-Save is a GST Voucher credit, not a tariff cut.
常见用途
- Checking a 4-room bill after a tariff jump.
- Seeing how air-con kWh dwarfs water in the total.
- Subtracting U-Save before querying an unusually high invoice.
示例
Example 1 — 400 kWh, 20 m³, Q4 2026, no U-Save. Electricity $114.36 + GST; water $64.70 + GST.
Example 2 — same kWh in Q3 2026. Electricity before GST rises to $127.64 because the tariff was 31.91 cents.
Example 3 — 50 m³ water. 10 m³ sits in the $1.81 / 65% WCT tier.
重要说明
Not your invoice. Meter dates, estimates and retailer plans differ.
Electricity changes every quarter. Re-check SP after each announcement.
Gas and conservancy are not included.
常见问题
What is the Singapore electricity tariff in Q4 2026?
28.59 cents per kWh before GST for households on the SP regulated tariff (announced 30 September 2026). GST at 9% is extra.
How is the water bill calculated?
PUB charges a two-tier tariff ($1.43 / $1.81 per m³), Water Conservation Tax at 50% / 65% of that tariff, and a $1.09 waterborne fee, then 9% GST.
Does this work if I switched to an electricity retailer?
No. Enter only if you still pay the regulated tariff, or treat the result as a benchmark against your retailer plan.
What is U-Save?
A GST Voucher credit for eligible HDB households, shown as a rebate on the SP bill. It is not automatic for private apartments.
Why is my bill higher than this estimate?
Air-conditioning, water heating, estimated reads, gas, refuse, late fees or a retailer contract can all differ. Compare kWh and m³ first.
Is GST included?
The headline cards include 9% GST. Component lines show amounts before GST as well.
Do I pay a sanitary appliance fee?
PUB folded used-water charges into the waterborne fee. This estimator does not add a per-fitting sanitary fee.
Is this SP or PUB advice?
No. Confirm tariffs on SP Group and PUB. Rates change.
