What changes the answer
The regulated electricity tariff changes quarterly and retailer plans can differ. Domestic water crosses a higher-price threshold above 40 m³, while other utility lines require separate reconciliation.

Singapore electricity bill calculator & home tools
Turn Singapore electricity and water meter readings into a transparent household utility estimate.
Quick answer
Calculate a Singapore electricity and water bill from meter readings
Start with previous and current electricity and water readings from the same bill. The combined tool labels the Q3 2026 regulated electricity rate, domestic water schedule and GST, while keeping a retailer plan and other account lines editable or separate.
- 01Subtract each previous meter reading from the current reading, or enter zero and the billed use.
- 02Confirm the electricity plan and rate period; a retailer contract may differ from the regulated rate.
- 03Apply domestic water components and GST, then reconcile gas, refuse, rebates, arrears and credits separately.
What people mix up
Metric units are standard; property listings may also show square feet. Both units remain visible during translation.
