1. What Is The Sri Lanka Electricity Bill Calculation?

The Sri Lanka electricity bill calculation estimates the total cost of electricity consumption based on tiered rates, fixed charges, and applicable taxes. This calculation helps consumers understand and predict their electricity expenses.

2. How Does The Calculator Work?

The calculator uses the electricity bill formula:

\[ Bill = Consumption \times Tiered Rate + Fixed Charge + (Consumption \times Tiered Rate + Fixed Charge) \times \frac{Taxes}{100} \]

Where:

\( Consumption \) — Electricity consumed in kilowatt-hours (kWh)
\( Tiered Rate \) — Rate per kWh in Sri Lankan Rupees (LKR)
\( Fixed Charge \) — Fixed monthly charge in LKR
\( Taxes \) — Applicable tax percentage

Explanation: The calculation first determines the base amount (consumption cost plus fixed charge), then adds the tax amount calculated as a percentage of the base amount.

3. Importance Of Electricity Bill Calculation

Details: Accurate electricity bill estimation helps consumers budget their expenses, understand consumption patterns, and identify potential savings through energy efficiency measures.

4. Using The Calculator

Tips: Enter electricity consumption in kWh, tiered rate in LKR per kWh, fixed charge in LKR, and tax percentage. All values must be non-negative numbers.
