Dubai DEWA Electricity & Water Bill Calculator

Dubai bills allocate electricity and water progressively through DEWA tariff slabs. Water has been billed in cubic metres since the March 2025 billing cycle. Enter the previous and current readings, choose the account category and confirm the fuel surcharges for the bill month. The calculator shows base slabs, August 2026 fuel surcharges, meter-service charges and VAT separately. Housing, sewerage, deposits, arrears, credits and other account-specific lines are not silently added.

This is an estimate, not an official DEWA bill. Confirm the account category, billing period, meter type and current fuel surcharge.

How this was calculated

Formula used

Usage = current − previous meter reading; base charge = progressive DEWA slabs; taxable subtotal = base charges + fuel surcharges + meter service; total = taxable subtotal + VAT + entered VAT-exempt lines

Your values in the formula

Electricity: 2,000 kWh × AED 0.23 + 500 kWh × AED 0.28 = AED 600.00. Water: 27 m³ × AED 7.7 + 3 m³ × AED 8.8 = AED 234.30. Fuel + meter service = AED 193.00; VAT = AED 1,027.30 × 5% = AED 51.37.

Assumptions and rounding

Water is billed in cubic metres from the March 2025 billing cycle.
Fuel surcharge defaults are specifically for August 2026 and must be changed for another period.
Housing, sewerage, deposits, arrears, credits and other account-specific lines are excluded unless entered as VAT-exempt lines.

The tool estimates the displayed tariff components. Account classification, billing dates, current fuel surcharge, municipality-related lines, sewerage, deposits, arrears, solar credits and other adjustments can change the official bill.

What the result means

Use it as a scenario

For 2,500 kWh and 30 m³ on a residential account, usage crosses the second electricity and water slabs before the August 2026 fuel surcharges, meter service and VAT are added.

What can change

Check before deciding

01Confirm the account category, bill month and meter type on the DEWA account.
02Water inputs must be cubic metres for bills from the March 2025 cycle onward.
