Bahrain Electricity and Water Bill Calculator
Estimate your monthly EWA bill in BHD from the kWh and cubic metres you use, slab by slab. Advanced adds meter readings, AC estimates, VAT and other charges from your bill, and a second month to compare.
The month's kWh from your EWA bill or app.
Only changes the cost per day. The slabs are monthly.
Check your EWA bill for any VAT or other charges.
Slab-by-slab breakdown
| Slab | Used | Fils each | Cost (BHD) |

How your bill is worked out
Each slab of use × its price in fils, electricity plus water.
- 1
Electricity slabs
4,000 kWh, 2 slabs
= BHD 18.000 - 2
Water slabs
70 m³, 2 slabs
= BHD 2.300 - 3
Add them up
18.000 + 2.300
= BHD 20.300 - 4
Cost per day
20.300 ÷ 30 days
= BHD 0.677

EWA (the Electricity and Water Authority) bills electricity in kilowatt-hours (kWh) and water in cubic metres (m³) each month, in fils: 1 Bahraini dinar (BHD) is 1,000 fils. The price depends on the type of account. A subsidised Bahraini home pays in slabs: the first block of the month's use is cheapest and each later block costs more. Non-Bahrainis, Bahrainis with more than one account and businesses pay the higher rates.
The formula
slab cost = units used in that slab × that slab's price in fils ÷ 1,000
electricity = sum of the electricity slab costs
water = sum of the water slab costs
bill = electricity + water (+ 10% VAT and other charges if your bill shows them)
cost per day = bill ÷ days in the bill
Worked example
A Bahraini family on one subsidised home account uses 4,000 kWh of electricity and 70 m³ of water in a 30-day bill.
- Electricity: the first 3,000 kWh × 3 fils = 9,000 fils = BHD 9.000, and the next 1,000 kWh × 9 fils = 9,000 fils = BHD 9.000, so electricity is BHD 18.000.
- Water: the first 60 m³ × 25 fils = 1,500 fils = BHD 1.500, and the next 10 m³ × 80 fils = 800 fils = BHD 0.800, so water is BHD 2.300.
- Bill: 18.000 + 2.300 = BHD 20.300, which is 20.300 ÷ 30 = BHD 0.677 a day (rounded).
- 1,000 more kWh would still be charged at 9 fils; above 5,000 kWh the price goes up to 16 fils.
- Without the subsidy the same use would cost 4,000 × 32 fils = BHD 128.000 plus 70 × 775 fils = BHD 54.250, so BHD 182.250.
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.
EWA tariffs
From EWA's tariff page, checked on 13 October 2026. Prices are in fils per kWh and fils per m³, for each monthly bill.
| Electricity | Fils/kWh |
|---|---|
| 0 – 3,000 kWh | 3 |
| 3,001 – 5,000 kWh | 9 |
| 5,001 – 7,000 kWh | 16 |
| Above 7,000 kWh | 32 |
| Water | Fils/m³ |
| 0 – 60 m³ | 25 |
| 61 – 100 m³ | 80 |
| Above 100 m³ | 775 |
| Electricity | Fils/kWh |
|---|---|
| All kWh | 32 |
| Water | Fils/m³ |
| All m³ | 775 |
| Electricity | Fils/kWh |
|---|---|
| 0 – 5,000 kWh | 22 |
| Above 5,000 kWh | 32 |
| Water | Fils/m³ |
| All m³ | 775 |
Who gets the subsidised rate
According to EWA's tariff page, the subsidy is for eligible Bahraini citizens, for one domestic account per household. It is applied automatically based on Information & eGovernment Authority data, and the account owner must be the registered Head of Household living at that address. Bahrainis with more than one account pay the same rates as non-Bahrainis (see the tables above).
Good to know
- Summer bills are often much higher because of air conditioning. On a subsidised account the extra kWh also move into dearer slabs, so the bill rises faster than the use.
- Water in litres or gallons is converted to m³: 1,000 litres = 1 m³, 1 imperial gallon = 0.004546 m³, 1 US gallon = 0.003785 m³.
- Check your EWA bill for any VAT or other charges. This calculator adds them only if you tick VAT or type other charges in Advanced. VAT, when ticked, is 10% of the electricity and water charges.

Common questions
How is an EWA bill worked out in Bahrain?
EWA charges electricity per kWh and water per cubic metre each month. For a subsidised Bahraini home the price rises in slabs: the first 3,000 kWh cost 3 fils each, the next 2,000 cost 9 fils, the next 2,000 cost 16 fils and anything above 7,000 kWh costs 32 fils. Each slab is worked out on its own and the slabs are added up. A subsidised home using 4,000 kWh and 70 m³ pays BHD 18.000 for electricity and BHD 2.300 for water, BHD 20.300 in total.
What do expats pay for electricity and water in Bahrain?
Non-Bahrainis, and Bahrainis with more than one account, pay one flat rate: 32 fils per kWh of electricity and 775 fils per cubic metre of water. So 2,000 kWh and 30 m³ in a month costs BHD 64.000 + BHD 23.250 = BHD 87.250.
Who gets the subsidised EWA rate?
According to EWA, the subsidised rate is for eligible Bahraini citizens, for one domestic account per household. It is applied automatically using Information & eGovernment Authority data, and the account owner must be the registered Head of Household living at that address.
Is there VAT on EWA bills?
This calculator does not assume it. If your EWA bill shows VAT, tick "Add VAT (10%)" in Advanced, and type any other charges from your bill. Check your EWA bill for any VAT or other charges.
How many cubic metres is a gallon?
One UK (imperial) gallon is 0.004546 m³ and one US gallon is 0.003785 m³. So 1,000 imperial gallons is about 4.55 m³, and 1,000 litres is exactly 1 m³. EWA bills water in cubic metres.
