1. What is the Sri Lanka Electricity Bill Calculation?

The Sri Lanka electricity bill calculation uses a slab-based system where different rates apply to different consumption levels. The total cost is the sum of consumption in each slab multiplied by its respective rate, plus any fixed charges.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Slab_i \) — Energy consumption in slab i (kWh)
• \( Rate_i \) — Rate per kWh in slab i (LKR/kWh)
• \( Fixed \) — Fixed charge (LKR)

Explanation: The calculation accounts for tiered pricing where different rates apply to different consumption levels, plus any fixed monthly charges.

3. Importance of Electricity Bill Calculation

Details: Understanding electricity billing helps consumers manage energy usage, budget effectively, and identify potential savings through energy efficiency measures.

4. Using the Calculator

Tips: Enter consumption for each applicable slab, the corresponding rates, and any fixed charges. All values must be valid non-negative numbers.
