## Operating Cycle Method for Estimating Working Capital
### What is the Operating Cycle?
The operating cycle is the time interval between the acquisition of raw materials and the collection of cash from the sale of finished goods. It represents the duration for which a firm has to negotiate Working Capital from its bankers.
### Why Use the Operating Cycle Approach?
- Helps in forecast, control and management of working capital.
- The length of the operating cycle is an indicator of management performance (shorter = more efficient).
- Enables accurate determination of working capital needed for continuous business operations.
- The cycle duration varies with the nature of business (e.g., a bakery has a short cycle, a shipbuilder has a very long one).
### The Operating Cycle Formula
> Operating Cycle = R + W + F + D − C
| Symbol | Meaning |
|---|---|
| R | Raw material storage period |
| W | Work-in-progress (WIP) holding period |
| F | Finished goods storage period |
| D | Debtors collection period |
| C | Credit period availed (from creditors) |
### Intuition Behind the Formula
- R + W + F + D = Gross operating cycle (time cash is locked from purchase to collection).
- Subtracting C gives the Net operating cycle — because suppliers finance part of the gap by giving us credit.
- The longer the net cycle, the more working capital is required.
### Key Takeaway
The net operating cycle tells you precisely how many days of working capital the firm must finance externally — making it the foundation of WC estimation.
