Cost Bridge — FY2022-23 → FY2023-24
Decomposition of change in Labour Rs/kg.
Rate = wage-rate change holding volume constant.
Volume = volume change holding wages constant.
Mix = structural shift in product mix (ideal Rs/kg change).

Volume Sensitivity (Labour + Power)
Based on 12-month actuals (4,223,283 kg). Labour modelled 90% fixed / 10% variable. Power modelled 35% fixed (demand charges) / 65% variable.

Sensitivity model assumes wages and JVVL demand charges are largely fixed in the short term. For production increases beyond current infrastructure, incremental capex costs are not captured here.
Data Sources & Methodology

Labour wages — KH-1 monthly wage files (department CPVC), authoritative for regular payroll. Contractor wages from UNIT-2 tab ("Paid Wages for Contractor Labour") — not separately verified against KH-1.

Fittings production (kg) — Report-12 (Wt in Kgs + Rejection), not the labour sheet which carries piece counts (mislabelled FY2026-27).

Ideal rates — Pipe Labour Rs 2.50/kg, Fitting Labour Rs 6.50/kg (from Ideal Labour Cost TOTAL row); Pipe Power Rs 4.00/kg, Fitting Power Rs 6.00/kg (from Ideal Power Cost TOTAL row). Verify with engineering if capacity norms have changed.

Power actuals — UNIT-2 tab of the annual workbook; per-kg cost uses Plumbing-only denominator. The "All-plant" per-kg (from Ideal Power Cost tab) uses Plumbing + Garden Pipe + HDPE + Tank denominator — the JVVL bill is a shared facility cost spread by volume.

Cost bridge — Labour only; uses 2-factor decomposition (Rate + Volume + Mix). Power bridge deferred pending prior-FY power tab loading.

Volume sensitivity — simplified model; actual Rs/kg at higher volumes depends on whether additional labour is required.
