Working capital = AR + Inventory − AP. Cash conversion cycle = DSO + Inv days − DPO. Reducing DSO by 10 days frees up ~27,39,726 in cash for this revenue.

How working capital is calculated

Working capital is the cash tied up in day-to-day operations. The simple operating definition is:

Working capital = Accounts Receivable + Inventory − Accounts Payable

Each component is computed from the relevant days metric:

  • Average AR balance = (Annual revenue × DSO) / 365
  • Average inventory = (Annual COGS × Inventory days) / 365
  • Average AP balance = (Annual COGS × DPO) / 365

The cash conversion cycle (CCC) is the number of days between paying for inventory and receiving cash from customers:

CCC = DSO + Inventory days − DPO

Why this matters

Working capital is cash you cannot use for growth, dividends or debt reduction. Reducing the CCC frees cash. The most common levers:

  • Cut DSO, better collections, smarter dunning, credit limit enforcement, early-payment discounts.
  • Cut inventory days, faster turns, better demand forecasting, dropship where possible.
  • Stretch DPO, negotiate longer terms with vendors (without straining the relationship).

Working capital FAQ

Common questions.

What is a "good" cash conversion cycle?

Highly variable by industry. Software / SaaS often has CCC near zero (subscription billing means receipts up front). Manufacturing typically runs 60-120 days. Retail (with fast inventory turns and trade credit) can be near zero or negative. The right benchmark is your own trend over time and direct competitors.

Why does reducing DSO matter so much?

Cash held in receivables is cash you cannot deploy. For a ₹100 Cr revenue business, every day of DSO is roughly ₹27L of cash. Cutting DSO by 10 days frees up ₹2.7 Cr permanently, without raising debt or equity. That cash can fund inventory growth, debt reduction or operations.

What about prepaid expenses, advances and other items?

The calculator focuses on the operating working capital (AR + Inventory − AP). The accounting definition of working capital (Current Assets − Current Liabilities) includes more items: cash, marketable securities, prepayments, accrued expenses, short-term debt. For operating decisions the simpler version is more actionable.

How can I track DSO / DPO / inventory days in real time?

These metrics are computed continuously inside OneFinOps from your AR, AP and inventory ledgers. The CFO and controller dashboards show DSO, DPO, inventory days, CCC and trend. No spreadsheet pull required.

How does this differ from a CFO operating-cash-flow view?

Operating cash flow includes profit, depreciation/amortisation and tax, not just working capital. The working capital calculation tells you the change in cash tied up in operations; the OCF calculation tells you the cash generated by operations. They are related but not the same.
