1. What is Slab-Based Electricity Billing?

Slab-based electricity billing is a system where different rates are applied to different consumption levels (slabs). In Haryana, this method ensures fair pricing where higher consumption is charged at higher rates.

2. How Does the Calculator Work?

The calculator uses the slab-based billing formula:

Where:

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

Explanation: The total cost is calculated by summing the products of energy consumption in each slab with their respective rates, then adding the fixed charge.

3. Importance of Slab Calculation

Details: Accurate slab calculation ensures correct billing, helps consumers understand their consumption patterns, and promotes energy conservation by incentivizing lower consumption in higher slabs.

4. Using the Calculator

Tips: Enter energy consumption for each slab in kWh, the corresponding rates in ₹/kWh, and the fixed charge in ₹. At least Slab 1 and Fixed Charge are required. All values must be non-negative.
