Operating Cycle, Cash Management & Economic Order Quantity (EOQ)
Idea in plain words
Gross Working Capital = Total Current Assets; Net Working Capital = Current Assets - Current Liabilities.
Exam tip
High-yield exam topic (High).
Explanation
Working capital management navigates the trade-off between profitability and liquidity. Holding excess current assets reduces insolvency risk but depresses return on assets; maintaining low working capital enhances profitability but exposes the enterprise to production halts and liquidity default.
Key points
- Operating Cycle: Time between purchasing raw materials and receiving cash from debtors: OC = Inventory Period + Debtors Period.
- Cash Conversion Cycle (CCC): CCC = Operating Cycle - Creditors Payment Period.
- Financing Policies: Matching / Hedging (mature matching), Conservative (long-term funds finance permanent and part of temporary CA), Aggressive (short-term funds finance temporary and part of permanent CA).
- Inventory Management: EOQ = √[(2 · Annual Demand · Ordering Cost) / Holding Cost per unit].
Example
Example
Cash Conversion Cycle: Inventory Conversion Period = 60 days, Receivables Collection Period = 40 days, Payables Deferral Period = 30 days. CCC = 60 + 40 - 30 = 70 days.
Code examples
// Economic Order Quantity (EOQ) Calculation in C++
#include <iostream>
#include <cmath>
using namespace std;
int main() {
double D = 10000; // Annual demand in units
double S = 250; // Ordering cost per order
double H = 5; // Carrying/holding cost per unit per year
double eoq = sqrt((2 * D * S) / H);
double totalOrders = D / eoq;
double totalCost = sqrt(2 * D * S * H);
cout << "Economic Order Quantity (EOQ): " << eoq << " units" << endl;
cout << "Optimal Number of Orders per Year: " << totalOrders << endl;
cout << "Total Inventory Carrying & Ordering Cost: NPR " << totalCost << endl;
return 0;
}
Exam questions
- [8 Marks] Explain the components of Working Capital. Calculate the Cash Conversion Cycle for a firm given relevant turnover figures.
- [7 Marks] Derive the EOQ formula. Given Annual Demand = 8,000 units, Ordering Cost = NPR 200, Carrying Cost = NPR 2/unit, calculate EOQ.
