Water Consumption Bill Estimator

What is the Water Consumption Bill Estimator?

Most Indian water utilities charge in slabs that rise with use. This water bill calculator applies your utility's slabs to your meter reading.

No meter reading? It estimates use from the number of people and litres per person.

How to use the Water Consumption Bill Estimator

1. Meter Reading for the Month (kL, 0 = estimate) (sample: 0)
2. People (if estimating) (sample: 4)
3. Litres per Person per Day (if estimating) (sample: 135)
4. Slab 1 Up To (kL) (sample: 8)
5. Slab 1 Rate (₹/kL) (sample: 7)
6. Slab 2 Up To (kL) (sample: 25)
7. Slab 2 Rate (₹/kL) (sample: 11)
8. Slab 3 Up To (kL) (sample: 50)
9. Slab 3 Rate (₹/kL) (sample: 26)
10. Rate Above Slab 3 (₹/kL) (sample: 45)
11. Sewerage / Sanitation Charge (% of water charge) (sample: 50)
12. Fixed / Meter Charge (₹ a month) (sample: 50)
13. Press Estimate Water Bill (results also refresh as you type). The result card shows the Monthly Water Bill, along with Water used, Water charge, Sewerage charge and Cost per kilolitre (all-in).

Formula used

Bill = Σ (kL in each slab × slab rate) × (1 + Sewerage %) + Fixed charge
