What Are Working Capital Holding Days?

Working capital holding days measure how long cash is locked up in each stage of the business cycle — from buying raw materials to collecting payment from customers. They are the primary inputs for Form IV (Current Assets & Liabilities) in CMA Data, which directly drives the MPBF calculation.

Think of the working capital cycle as a pipeline: raw materials go in one end, and cash comes out the other. The longer the pipeline, the more working capital the business needs — and the higher the justified bank finance (MPBF).

The 5 Working Capital Components
Raw Materials → Work-in-Progress → Finished Goods → Debtors → Cash
Minus: Creditors (funded by suppliers, not the bank)

Raw Material (RM) Days

Raw Material days measure how many days' worth of raw material the business keeps in stock before it enters production.

Formula: RM Days = (Closing RM Stock ÷ Raw Material Consumed) × 365

IndustryTypical RM DaysReason
Jewellery / Gold30–45 daysHigh-value material; minimal buffer held
Textile / Apparel45–60 daysSeason-dependent buying cycles
Pharma / Chemicals45–90 daysImported RM with long lead times
Food Processing15–30 daysPerishable inputs, short shelf life
Steel / Metals30–45 daysBulk procurement from mills
Trading Business30–60 daysStock holding for sale
Bank Scrutiny: If your RM days are significantly higher than the industry norm, the bank will ask why. Legitimate reasons include long supply chains, seasonal procurement (e.g., agri-raw materials), or imported materials with transit time. Always be ready to justify.

WIP (Work-in-Progress) Days

WIP days measure how long material spends being converted into a finished product in the factory. For service businesses with no manufacturing, WIP = 0.

Formula: WIP Days = (Closing WIP Stock ÷ Cost of Production) × 365

WIP is valued at cost of raw material + labour + manufacturing overhead consumed up to that stage. In practice:

Finished Goods (FG) Days

Finished Goods days measure how long manufactured goods are held in the warehouse before being sold and dispatched.

Formula: FG Days = (Closing FG Stock ÷ Cost of Goods Sold) × 365

IndustryTypical FG Days
FMCG / Food7–15 days
Textile / Apparel30–45 days
Pharma30–60 days
Engineering / Machinery20–45 days
Electronics15–30 days
Steel / Metals15–30 days

Debtor Days (DSO — Days Sales Outstanding)

Debtor days measure how long it takes customers to pay after a sale is made. This is the largest working capital component for most businesses.

Formula: Debtor Days = (Closing Debtors ÷ Net Sales) × 365

Banks are particularly attentive to debtor days because high debtors can signal:

Bank Benchmark: Most PSU banks allow debtor days up to 90 days for manufacturing and 60 days for trading. Service sector debtors can vary widely — IT companies may show 45–75 days, while government contractors can show 120+ days.

If your debtor days exceed the norm, banks will ask for an ageing analysis — how much is current (0–30 days), how much is overdue (31–90 days), and what is sticky / bad (90+ days).

Creditor Days (DPO — Days Payable Outstanding)

Creditor days measure how long the business takes to pay its suppliers. Creditors are a free source of working capital — the longer you can delay payment to suppliers, the less bank finance you need.

Formula: Creditor Days = (Closing Creditors ÷ Purchases) × 365

In the MPBF calculation, creditors are deducted from current assets — reducing the bank finance requirement. Higher creditor days = lower MPBF = smaller CC/OD limit.

Key Point: Artificially inflating creditor days to reduce MPBF and show a better current ratio is a common manipulation that banks detect by cross-checking creditor ageing with GST purchase data (GSTR-2B). Keep creditor days realistic.

The holding days translate into rupee values for each working capital component, which are totalled in Form IV of the CMA:
