How much is a leak costing you? Water Bill Waste Calculator
Enter your usual monthly consumption and the consumption on your latest bill in cubic meters (both are printed on your bill). The tool estimates the likely waste in liters per day and its monthly and yearly cost.
Tariff & currency: Saudi NWC tiers (default)
Check your local utility's price per m³. Leak volumes (liters, m³) don't depend on the tariff — only the cost does. Saved in this browser only.
How is it calculated?
By default the water charge uses the Saudi National Water Company (NWC) residential tiers below, plus sewerage at 50% of the water charge, then 15% VAT. Outside Saudi Arabia, set your own price per m³ and currency under "Tariff & currency". The difference between the cost of your current and usual consumption is what the waste adds to your bill.
| Monthly consumption tier | Price |
|---|---|
| 1 – 15 m³ | SAR 0.10/m³ |
| 16 – 30 m³ | SAR 1.00/m³ |
| 31 – 45 m³ | SAR 3.00/m³ |
| 46 – 60 m³ | SAR 4.00/m³ |
| More than 60 m³ | SAR 6.00/m³ |

Confirm before you pay: the meter test
The fastest way to tell whether there is a leak is to watch the meter with every tap closed. Start the interactive meter test →

Frequently asked questions
How do I know a higher bill is caused by a leak?
Compare your current consumption with your usual average for similar months. If usage went up without more people at home or a change in habits (such as watering the garden or filling a pool), a hidden leak is the usual cause, and the fastest confirmation is the water meter test.
Does this match my bill exactly?
No. It is an estimate based on the tariff shown on this page — Saudi NWC tiers by default, or the price per m³ you enter under "Tariff & currency". Your bill may include other fees or a different reading period; your water utility's bill is the final reference.
How many liters can a small leak waste per day?
It depends on the type of leak. A leaking tank or a hidden joint can waste hundreds of liters a day without being visible, which is why the calculator works out the daily waste from the consumption difference itself.
What should I do if the calculator shows waste?
Run the water meter test to confirm, then book a non-destructive leak detection inspection to pinpoint the location before any repair. On-site service is available in Saudi Arabia only.
