About the DEWA Bill Estimator

DEWA bills combine several components: slab-rate consumption charges (the more you use, the higher the per-unit rate), a fuel surcharge that moves monthly with fuel prices, and 5% VAT. This calculator estimates your monthly bill from your electricity and water usage. It's useful for sanity-checking a bill that looks unexpectedly high, comparing usage before and after adding appliances like a second AC unit or a pool pump, or budgeting for a new apartment before you've moved in and received a first bill.

How it works

Electricity and water consumption are each charged on progressive slabs — usage within each band is charged at that band's rate, not the whole amount at the top rate.
A fuel surcharge is added per kWh and per m³, based on DEWA's published monthly rate.
5% VAT is added to the subtotal.

Assumptions and behaviour

Uses residential slab tariffs — commercial/industrial tariffs differ.
The fuel surcharge is a snapshot taken from DEWA's published rate at the time this tool was built — DEWA states it varies monthly with fuel prices, so treat it as directional, not exact.
Doesn't include the fixed housing fee (a flat municipality charge collected via DEWA, based on property type/size) some residents also see on their bill.

Limitations

Doesn't include the separate housing fee or meter/service charges some accounts carry.
The fuel surcharge changes monthly — check DEWA's current tariff page for the live figure before relying on this for budgeting.
Estimates only. Your actual DEWA bill may differ.

Frequently asked questions

Is this DEWA bill estimator free?

Yes — free, no sign-up, no limits, runs in your browser.

Why does my bill change every month even with similar usage?

DEWA's fuel surcharge moves with fuel prices, so it can vary month to month even at identical consumption levels.

Does this include VAT?

Yes — 5% VAT is added to the consumption and fuel surcharge subtotal, matching how DEWA bills are structured.

Is my data uploaded?

No. Everything runs locally in your browser; nothing is sent or stored.

Why is my DEWA bill higher in summer?

Air conditioning drives most residential electricity use in the UAE, and summer cooling load pushes consumption into DEWA's higher-priced slabs. The same kWh usage costs more per unit once you cross into a higher band, which is why summer bills often jump more than the extra hours of AC alone would suggest.

Does this cover the DEWA housing fee?

No. The housing fee is a separate flat municipality charge (based on property type and size) that some residents see added to their DEWA bill alongside consumption charges — it isn't part of this estimate.
