What Is the FEWA Electricity Bill Calculator?
The FEWA Calculator is a free online tool designed specifically for residents of the UAE's Northern Emirates. It uses the official slab-based tariff structure from Etihad Water and Electricity (formerly Federal Electricity and Water Authority) to calculate your estimated electricity costs.
This calculator helps you:
- Estimate monthly electricity costs before receiving your official bill
- Compare consumption patterns across different usage scenarios
- Plan household budgets with greater accuracy
- Identify opportunities to reduce energy consumption and save money
Our calculator incorporates the latest 2025 tariff rates, including the 5 fils/kWh fuel surcharge applied to most consumer categories. Whether you're an Emirati citizen benefiting from subsidized rates or an expatriate navigating the slab system, this tool provides transparent cost breakdowns.
For residents in Dubai, you may want to use our Dubai electricity bill estimator instead, as DEWA operates under different tariff structures.

How the FEWA Electricity Calculator Works
The calculator uses EtihadWE's official slab-based tariff system to determine your electricity costs. Here's the methodology behind the calculations:
Understanding the Slab System
FEWA charges different rates depending on your consumer category and how much electricity you use. The more you consume, the higher your per-unit rate becomes for consumption above certain thresholds. This tiered approach encourages energy conservation.
Calculation Formula
For expatriate residential customers, the calculation follows this structure:
Total Bill = (Units in Slab 1 × Rate 1) + (Units in Slab 2 × Rate 2) + (Units in Slab 3 × Rate 3) + (Units in Slab 4 × Rate 4) + Fuel Surcharge
The fuel surcharge is calculated as: Total kWh × 0.05 AED (5 fils per kWh)
Current Electricity Tariff Rates (Expatriate Residential)
| Tariff (Fils/kWh) | With Surcharge (Fils/kWh) | |
|---|---|---|
| Up to 2,000 kWh | 23 | 28 |
| 2,001 – 4,000 kWh | 28 | 33 |
| 4,001 – 6,000 kWh | 32 | 37 |
| Above 6,000 kWh | 38 | 43 |
UAE Citizen Rates
Emirati citizens enjoy a flat subsidized rate of 7.5 fils per kWh with no fuel surcharge, regardless of consumption level. This represents significant government support for national households.
Step-by-Step Calculation Process
- Select your consumer category (UAE Citizen, Expatriate Residential, Commercial, or Industrial)
- Enter your total electricity consumption in kilowatt-hours (kWh)
- The calculator applies the appropriate slab rates to each portion of your consumption
- Fuel surcharge is added where applicable
- Your estimated total bill is displayed with a detailed breakdown

Practical Examples: FEWA Bill Calculations
Here are three realistic scenarios showing how the calculator works for different household situations in the Northern Emirates.
Example 1: Small Apartment in Ajman (Expatriate)
Scenario: Ahmed lives in a one-bedroom apartment in Ajman City Center. He works long hours and uses minimal electricity during weekdays. His monthly consumption is approximately 1,200 kWh.
Calculation:
- All 1,200 kWh falls within Slab 1 (up to 2,000 kWh)
- Electricity cost: 1,200 × 0.23 = AED 276.00
- Fuel surcharge: 1,200 × 0.05 = AED 60.00
- Total Estimated Bill: AED 336.00
Ahmed's efficient usage keeps him entirely within the lowest rate slab, maximizing his savings.
Example 2: Family Villa in Ras Al Khaimah (Expatriate)
Scenario: The Singh family lives in a three-bedroom villa in RAK. With two children, home-based work, and air conditioning running during summer months, their consumption reaches 4,500 kWh in peak season.
Calculation:
- First 2,000 kWh × 0.23 = AED 460.00
- Next 2,000 kWh (2,001–4,000) × 0.28 = AED 560.00
- Remaining 500 kWh (4,001–4,500) × 0.32 = AED 160.00
- Fuel surcharge: 4,500 × 0.05 = AED 225.00
- Total Estimated Bill: AED 1,405.00
The family could save approximately AED 180 monthly by reducing consumption below 4,000 kWh through better AC management. Consider using our air conditioning sizing tool to ensure your units are properly matched to room sizes.
Example 3: UAE Citizen Family in Fujairah
Scenario: The Al Mazrouei family resides in a government-provided villa in Fujairah. Their large household of seven members consumes approximately 8,000 kWh monthly.
Calculation:
- All consumption at flat citizen rate: 8,000 × 0.075 = AED 600.00
- No fuel surcharge applies to UAE citizens
- Total Estimated Bill: AED 600.00
Compare this to an expatriate with identical consumption, who would pay approximately AED 3,140.00 – demonstrating the substantial subsidy provided to Emirati households.
Important Information About FEWA Billing

If you're in Sharjah City, use the Sharjah electricity calculator for accurate estimates.
Commercial and Industrial Rates
Business customers face the same slab structure as expatriate residents for commercial properties. Industrial connections pay a flat rate of 40 fils/kWh plus 4 fils surcharge regardless of consumption volume.
Common Billing Mistakes to Avoid
- Ignoring meter readings: Always verify your bill matches actual meter readings. Estimated bills can accumulate discrepancies.
- Forgetting surcharges: The 5 fils fuel surcharge adds approximately 22% to expatriate bills. Factor this into your budget.
- Overlooking payment deadlines: Late payments may incur disconnection fees. Set up auto-pay through your bank or the EtihadWE app.
- Not monitoring seasonal spikes: Summer AC usage can triple consumption. Plan for June–September increases.
Energy-Saving Tips
Reduce your FEWA bill by implementing these practical measures:
- Set AC thermostats to 24°C – each degree lower increases consumption by 6–8%
- Use LED lighting throughout your home
- Run washing machines and dishwashers with full loads only
- Service air conditioning units before summer begins
- Install a programmable thermostat for automatic temperature management

Frequently Asked Questions
How accurate is this FEWA calculator?
The calculator uses official EtihadWE tariff rates published on their website. Results are estimates based on electricity consumption only. Your actual bill may include water charges, municipality fees, and any outstanding balances. Consider this a close approximation for budgeting purposes.
What's the difference between FEWA and EtihadWE?
They are the same organization. The Federal Electricity and Water Authority (FEWA) was rebranded to Etihad Water and Electricity (EtihadWE) in 2021 after being transferred to the UAE's sovereign wealth fund. All services, tariffs, and customer accounts remain unchanged.
Why is my actual bill higher than the calculator estimate?
Several factors can cause differences: water consumption charges (separate tariff structure), municipal fees, previous unpaid balances, meter deposits, or billing for a period longer than 30 days. This calculator focuses solely on electricity costs.
How do I read my electricity meter to input consumption?
Digital meters display current readings directly. Subtract your previous month's reading from the current reading to get monthly consumption in kWh. Smart meters connected to EtihadWE's network automatically transmit this data. You can also check consumption via the EtihadWE mobile app or customer portal.
Do FEWA rates change during summer months?
No, FEWA maintains consistent tariff rates throughout the year. However, your consumption naturally increases during hot months due to air conditioning demands, resulting in higher bills despite unchanged rates.
Can I use this calculator for my shop or office?
Yes, select "Commercial" as your consumer category. Commercial properties follow the same slab structure as expatriate residential accounts. For industrial facilities, choose "Industrial" for the flat-rate calculation.
How can I reduce my FEWA electricity bill?
Focus on AC efficiency (your biggest expense), switch to LED bulbs, use energy-efficient appliances with high star ratings, and avoid running appliances during peak afternoon hours. The EtihadWE website offers free energy audits for high-consumption accounts.
Is the 5% VAT included in the calculator?
This calculator provides pre-VAT estimates. Add 5% to your final result for a VAT-inclusive total. Utility bills in the UAE are subject to standard value-added tax.
