Electric Bill Calculator

This tool estimates electricity charges by applying tariff slabs to monthly consumption (kWh), plus fixed charges and taxes, to produce a bill projection.
When tariff_slabs are provided, it computes per-slab charges and aggregates them into a total base amount. If tariff_slabs are omitted, default tier rates are used. Optional inputs allow fixed charges, additional meter rents, and a tax rate to reflect local policy.
The primary audience includes homeowners, property managers, and energy analysts who want to project monthly costs, compare tariff options, and budget accurately. The tool emphasizes clear, auditable outputs with a complete breakdown by slab, fixed components, and tax, enabling easy reconciliation with actual utility bills. Unique value lies in supporting region-specific tariff structures while offering sensible defaults and a transparent calculation trail for audits and planning.
Core features include: slab-based calculation, default tier fallback, optional fixed charges and taxes, currency support, and an exportable breakdown. Use cases include monthly bill estimation, tariff option comparisons, and expense planning for households and small facilities.
