Sharjah Electricity and Water Bill Calculator (SEWA)
Estimate your monthly SEWA bill in AED from the kWh and gallons you use, slab by slab, with the fuel surcharge and 5% VAT. Advanced adds meter readings, AC estimates, your own rate and a second month to compare.
Residential (Local/Expat). These are the slabs used by SEWA's own Home Energy Calculator. Commercial, industrial and agricultural accounts may be billed differently — check your bill.
The month's kWh from your SEWA bill.
In gallons, as on SEWA's calculator.
For a commercial, industrial or agricultural account, type the price per unit from your bill. It replaces the slabs; the fuel surcharge and 5% VAT are still added. Leave blank for SEWA's slabs.
Only changes the cost per day. The slabs are monthly.

Electricity slabs
3,000 kWh in 2 slabs

Water slabs
5,000 gal in 1 slab
= AED 175.00 - 3
Fuel surcharge

1,120.00 × 1.05
= AED 1,176.00
Read more: the SEWA slabs, the formula, a worked example and tips
SEWA (Sharjah Electricity, Water and Gas Authority) bills electricity in kilowatt-hours (kWh) and water in gallons each month, priced in fils: 100 fils = 1 AED. Both are charged in slabs: the first block of the month's use at the lowest price and each later block at a higher price. A fuel surcharge is added on every kWh and every gallon, and 5% VAT goes on the total.
The formula
slab cost = units used in that slab × that slab's price in fils ÷ 100
electricity = sum of the electricity slab costs
water = sum of the water slab costs
fuel surcharge = kWh × 6 fils ÷ 100 + gallons × 0.5 fils ÷ 100
before VAT = electricity + water + fuel surcharge
bill = before VAT × 1.05
cost per day = bill ÷ days in the bill
Worked example
A home (Residential, Local or Expat) uses 3,000 kWh of electricity and 5,000 gallons of water in a 30-day bill.
- Electricity: the first 2,000 kWh × 23 fils = 46,000 fils = AED 460.00, and the next 1,000 kWh × 28 fils = 28,000 fils = AED 280.00, so electricity is AED 740.00.
- Water: all 5,000 gallons are in the first slab, 5,000 × 3.5 fils = 17,500 fils = AED 175.00.
- Fuel surcharge: 3,000 kWh × 6 fils = AED 180.00, and 5,000 gallons × 0.5 fils = AED 25.00, so AED 205.00.
- Before VAT: 740.00 + 175.00 + 205.00 = AED 1,120.00. VAT: 1,120.00 × 5% = AED 56.00.
- Bill: 1,120.00 + 56.00 = AED 1,176.00, which is 1,176.00 ÷ 30 = AED 39.20 a day.
- 1,000 more kWh would still be charged at 28 fils; above 4,000 kWh the price goes up to 32 fils. 1,000 more gallons would still be at 3.5 fils; above 6,000 gallons it is 4.0 fils.
Estimating kWh from your AC
AC kWh = AC units × tons × kW per ton × hours a day × days
1 ton = 12,000 BTU/h = 3.517 kW of cooling
Three 1.5 ton standard split units (1.3 kW per ton) running 14 hours a day use 3 × 1.5 × 1.3 × 14 = 81.9 kWh a day, or 2,457 kWh in 30 days. Add 10 kWh a day for everything else (300 kWh) and the month is 2,757 kWh. In winter at 4 hours a day the same AC uses 702 kWh.
SEWA slabs
From SEWA's Home Energy Calculator, checked on 13 October 2026. The slabs are per month. These are the slabs used by SEWA's own Home Energy Calculator. Commercial, industrial and agricultural accounts may be billed differently — check your bill.
| Use in the month | Fils/kWh |
|---|---|
| 0 – 2,000 kWh | 23 |
| 2,001 – 4,000 kWh | 28 |
| 4,001 – 6,000 kWh | 32 |
| 6,001 kWh and above | 38 |
| Use in the month | Fils/gallon |
|---|---|
| 0 – 6,000 gallons | 3.5 |
| 6,001 – 12,000 gallons | 4.0 |
| 12,001 gallons and above | 4.6 |
| Charge | Fils |
|---|---|
| Electricity fuel surcharge, per kWh (all units) | 6.0 |
| Water fuel surcharge, per gallon (all units) | 0.5 |
| VAT on consumption + fuel surcharge | 5% |
Good to know
- Summer bills are often much higher because of air conditioning, and the extra kWh fall into the dearer slabs, so the bill rises faster than the use.
- Water in m³ or litres is converted to gallons, assuming imperial gallons: 1 m³ = 219.969 gallons = 1,000 litres.
- For a commercial, industrial or agricultural account, use "Use my own rate" in Advanced with the price per unit from your bill.

Common questions
How is a SEWA bill worked out in Sharjah?
SEWA charges electricity per kWh and water per gallon in slabs: the first block of the month's use is cheapest and each later block costs more. Each slab is worked out on its own and the slabs are added up. A fuel surcharge of 6 fils per kWh and 0.5 fils per gallon is added on all units, then 5% VAT on the total. A home using 3,000 kWh and 5,000 gallons in a month pays AED 740.00 for electricity, AED 175.00 for water and AED 205.00 fuel surcharge, AED 1,120.00 before VAT and AED 1,176.00 with VAT.
What are the SEWA electricity slabs?
In SEWA's own Home Energy Calculator: 0 – 2,000 kWh at 23 fils, 2,001 – 4,000 kWh at 28 fils, 4,001 – 6,000 kWh at 32 fils, and 6,001 kWh and above at 38 fils per kWh, for each monthly bill. 100 fils = 1 AED.
What are the SEWA water slabs?
In SEWA's own Home Energy Calculator water is charged per gallon: 0 – 6,000 gallons at 3.5 fils, 6,001 – 12,000 gallons at 4.0 fils, and 12,001 gallons and above at 4.6 fils per gallon each month.
What is the SEWA fuel surcharge?
A charge on every unit used, on top of the slab price: 6.0 fils per kWh of electricity and 0.5 fils per gallon of water, in SEWA's own Home Energy Calculator. 5% VAT is then charged on the consumption charges plus the fuel surcharge.
How many gallons are in a cubic metre?
Assuming imperial gallons, one cubic metre is 219.969 gallons, so 1,000 gallons is about 4.55 m³ and the first water slab of 6,000 gallons is about 27.3 m³. 1,000 litres is exactly 1 m³.
