DEWA Bill Calculator Dubai
This free calculator estimates your monthly DEWA bill for a Dubai home from three inputs: your electricity use in kWh, your water use in cubic metres, and your annual rent. It applies DEWA's tiered electricity and water slabs, the fuel surcharge, the sewerage charge and the 5% housing fee, and shows the breakdown so you can see where the money goes.
DEWA Bill Estimator
Your DEWA bill combines electricity charged in rising kWh slabs (23, 28, 32, 38 fils),
water charged per cubic metre (7.70, 8.80, 10.12 dirhams), a fuel surcharge, sewerage, and a 5% municipality
housing fee on your annual rent. Drag the sliders to estimate each part.
How it's calculated
Electricity = each kWh slab charged at 0.23, 0.28, 0.32 then 0.38 dirhams, plus a 0.06 fuel surcharge per kWh. Water = the cubic-metre slab rate (7.70, 8.80, 10.12) plus 1.10 fuel and 0.33 sewerage per cubic metre. Housing fee = 5% of your annual rent divided by 12. Example: 1,800 kWh sits in the first slab, so 1,800 times 0.23 is 414, plus 108 fuel makes 522 for electricity; 20 cubic metres of water is 154 plus 22 plus 6.60, about 183; a 90,000 rent adds 375 housing; total near 1,080 dirhams a month.
Indicative only. Verify with your DEWA account. Housing fee is billed via DEWA on behalf of Dubai Municipality.

How is a DEWA bill worked out?
A DEWA bill is four things added together. Electricity is charged on a rising slab scale, so the more you use in a month the higher the rate on the top units. Water works the same way on a separate slab scale measured in cubic metres. On top of both sits a fuel surcharge that moves with fuel costs, and a sewerage charge on water. Finally, a housing fee equal to 5% of your annual rent, divided across twelve months, appears on the DEWA bill because DEWA collects it on the municipality's behalf.
Why is my DEWA bill higher in summer?
Air conditioning. From roughly May to September a Dubai villa can pull two to three times the electricity of a mild month, and because the top units are billed at the highest slab rate, the bill rises faster than the usage does. A poorly serviced AC, a low thermostat setting and weak insulation all push it up further. The single biggest lever most homes have is AC efficiency, which is why a serviced, correctly sized system pays for itself over a summer.
What the calculator does not include
It estimates the recurring monthly charges. It does not include one-off items such as your initial security deposit or a new-connection activation fee, and it uses standard residential slab rates rather than any special commercial or industrial tariff. Treat the figure as a close estimate for budgeting, not an exact reproduction of your statement.
How to bring the bill down
Service the AC before summer and keep filters clean, set the thermostat a couple of degrees higher, close off unused rooms, and fix any water leaks quickly because a running toilet or a dripping tank pushes the water slab up silently. On larger homes, smart controls that stop cooling empty rooms make a measurable difference across a season.
If your bill looks wrong for the size of your home, an electrical and cooling check often finds the cause. See AC maintenance and servicing or electrical works.
