DEWA Bill Calculator

A DEWA bill is the monthly statement issued by the Dubai Electricity and Water Authority. It covers your electricity and water consumption, along with related service charges.

Please note that while the calculator provides an estimate, actual bills may vary slightly due to updated surcharge rates or service adjustments.

What are the components of a DEWA bill?

Before using the DEWA calculator, it is important to understand what goes into the total.

How consumption charges are calculated

Electricity and water are billed using a slab system. In other words, the more you consume, the higher the rate per unit becomes once you cross certain thresholds.

• For electricity, charges are calculated per kilowatt-hour (kWh).
• For water, charges are calculated per cubic metre (m³). Since March 2025, water billing has officially shifted from gallons to cubic metres.

The slab system encourages conservation. Staying within lower slabs results in lower rates. Crossing into higher slabs increases the cost per unit.

What fixed fees and surcharges include

In addition to usage, your bill may include:

• Meter service charge depends on the meter type.
• Fuel surcharge, calculated per kWh (electricity) and per m³ (water).
• Sewerage fee, based on water consumption.

The fuel surcharge changes periodically. Therefore, even if your usage remains the same, your total bill may differ slightly month to month.

Additional charges

Some charges depend on residency status.

• Housing fee: For expatriates, this equals 5% of the annual rent. It is divided into 12 monthly instalments and added to the bill.
• VAT: A 5% tax applied to VAT-applicable components of the bill.

DEWA tariffs and rates in 2026

Understanding current slabs ensures your calculations remain accurate.

Electricity Rate Slabs in Dubai

• Residential and commercial:

• Industrial:

• Fuel Surcharge: AED 0.060/kWh
• Meter Service Charge: Starts from AED 5 up to AED 35

Water rate slabs

• Residential:

If you live in a villa, expect a higher average for water bills than those living in apartments, due to landscaping and pools.

• Commercial and industrial:

• Fuel Surcharge: AED 1.100/m³
• Meter Service Charge: Starts from AED 5 up to AED 7

How to calculate your DEWA bill step by step

If you prefer manual calculation, then you can just follow these steps carefully.

First, obtain your monthly consumption:

• Electricity usage in kWh
• Water usage in m³

Next, apply slab rates:

• Divide electricity usage into slab ranges
• Multiply each portion by its respective rate
• Repeat the process for water

Then, add additional charges:

• Fuel surcharge (usage × surcharge rate)
• Sewerage fee
• Meter service fee
• Housing fee (5% of annual rent ÷ 12) if applicable

After calculating the subtotal, apply 5% VAT on VAT-applicable components. Then, sum everything to determine the estimated total bill. Finally, pay your DEWA bills.

Although this process is manageable, most UAE residents prefer using a DEWA calculator for speed and clarity.

Example calculation of a monthly bill

Let us assume the following monthly usage:

• Electricity: 3,000 kWh
• Water: 60 m³

Electricity calculation

• First 2,000 kWh × 0.230 AED = 460 AED
• Next 1,000 kWh × 0.280 AED = 280 AED
  Electricity subtotal = 740 AED

Water calculation

• First 27 m³ × 7.70 AED = 207.90 AED
• Remaining 33 m³ × 8.80 AED = 290.40 AED
  Water subtotal = 498.30 AED

Fuel surcharge (electricity only example)

3,000 kWh × 0.060 AED = 180 AED

Add other charges

• Sewerage fee (variable)
• Meter service charge
• Housing fee (if the tenant expatriate)

Assume the subtotal before VAT equals 1,500 AED.
VAT at 5% = 75 AED.

Final estimated bill = 1,575 AED.

DEWA on ChatGPT

In February 2026, DEWA made headlines by being the very first government entity in the world to offer services through ChatGPT. The initiative allows residents to access selected information and support services through conversational AI, alongside DEWA’s existing digital channels.

This development is a part of a broader push toward smart government services in Dubai. While official bills and calculations remain available on DEWA’s website and in approved tools, the addition of AI platforms provides another channel for users to obtain general guidance on tariffs, billing components, and consumption details.

Practical tips to reduce your DEWA bill

Lowering your DEWA bill is often easier than expected. Small behavioural adjustments can make a noticeable difference. If you want to reduce your bills, consider the following:

• Set air conditioning thermostats slightly higher during summer.
• Use programmable timers for cooling systems.
• Seal windows and doors to reduce heat leakage.
• Install energy-efficient LED lighting.
• Repair any water leaks right away.
• Monitor consumption monthly.
• Install water-saving showerheads and taps.
• Avoid excessive outdoor irrigation.

Key takeaways

• The DEWA calculator helps estimate your monthly electricity and water costs accurately before receiving the official bill.
• Electricity and water are billed using slab tariffs, where higher consumption leads to higher per-unit rates.
• Fuel surcharge, sewerage fees, housing fee (for expatriates), and 5% VAT affect the final bill.
• Monitoring usage and reducing consumption during peak seasons can lower your overall costs.
