1. What is the Water Bill Calculation?

The Water Bill Calculation formula estimates the total water bill based on consumption, tiered rates, fixed charges, and applicable taxes in Sri Lanka. It provides an accurate assessment of water usage costs for residential and commercial customers.

2. How Does the Calculator Work?

The calculator uses the water bill formula:

\[ Bill = Fixed\ Charge + (Consumption \times Tiered\ Rate) + VAT\ (12\%) + Service\ Charge \]
