Dubai DEWA Electricity & Water Slab Calculator

Dubai electricity and water bills use progressive consumption slabs, and current fuel surcharges are published separately. Enter the billing-period kWh, water in imperial gallons and the current surcharge figures from DEWA. The base slab schedule is labelled with its review date, each block is calculated visibly, and municipality fees, VAT, housing fee, arrears or account-specific lines are not silently added.

What to have beside you

Use the current bill or tariff sheet, exact product label, location-specific solar estimate, or measured project dimensions. Example physical values teach the tool; zero money rates prevent an unsourced price from becoming a default claim.

How this was calculated

Formula used

Each slab charge = consumption within that slab × published base rate; fuel surcharge = total consumption × entered current surcharge

Your values in the formula

Electricity: 2,000 kWh × AED 0.23 + 500 kWh × AED 0.28 = AED 600.00; water: 6,000 gal × AED 0.035 + 1,000 gal × AED 0.04 = AED 250.00

Assumptions and rounding

Base slab configuration reviewed 2026-07-21 against the linked DEWA page.
Fuel surcharges default to zero so a changing monthly surcharge is never silently invented.
VAT, housing fee, sewerage, arrears and account-specific items are excluded.

The calculator covers the displayed residential base slabs and entered fuel surcharges. VAT, housing fee, sewerage, deposits, arrears, minimum charges and account classification may change the bill.

At 2,500 kWh, the first 2,000 kWh is priced in the first electricity slab and the next 500 kWh in the second before the entered fuel surcharge.
