Corrugated Costing Framework: From Raw Material to Margin

Corrugated box cost is a moving target; raw material alone accounts for 60‑70% of the final price. This guide walks you through a data‑first costing framework that turns every ₹ spent into a clear margin contribution.

1. Define the Scope – What Does the Cost Include?

Cost Component	Typical % of Total	Example
Paper & Flute	60‑70%	₹50‑₹60/kg
Labor	10‑15%	₹0.5/box
Overheads	10‑15%	Rent, utilities
Profit Margin	10‑15%	Final price

Key Point: Ignoring small overheads can distort margin by 2‑3%.

2. Build the Raw Material Sheet

2.1 Gather Current Paper Prices

Paper Type	GSM	Price ₹/kg
Virgin Kraft Liner	180	₹60
Recycled Test Liner	150	₹48

2.2 Calculate Paper Cost per Box

Scenario: A factory orders 50,000 500×300×200 mm boxes and wants to compare virgin vs recycled liners.

Liner Type	GSM	Price ₹/kg
Virgin Kraft	180	₹60
Recycled Test	150	₹48

Calculation

Cost per box = (Area × GSM ÷ 1000) × Price.

Area = 0.5 m × 0.3 m × 2 = 0.3 m².
Virgin: (0.3×180/1000)×₹60 = ₹3.24.
Recycled: (0.3×150/1000)×₹48 = ₹2.16.
Savings: ₹1.08 per box → ₹54,000 on 50,000 boxes.

3. Add Labor & Overheads

Item	Rate	Qty	Cost
Cutting	₹0.30/box	50,000	₹15,000
Folding	₹0.20/box	50,000	₹10,000
Overheads	₹0.50/box	50,000	₹25,000

Total non‑paper cost = ₹50,000.

4. Compute Total Cost and Margin

Total Cost per Box = Paper + Labor + Overheads.

Virgin: ₹3.24 + ₹1.50 + ₹0.50 = ₹5.24.
Recycled: ₹2.16 + ₹1.50 + ₹0.50 = ₹4.16.

Assuming a selling price of ₹8 per box, margin is:

Virgin: ₹8 – ₹5.24 = ₹2.76 (34.5%).
Recycled: ₹8 – ₹4.16 = ₹3.84 (48.0%).

Key Point: A ₹1.08 saving per box boosts margin by 13.5%.
