A business can be profitable on paper and still fail because it cannot pay its staff on Friday. A company can also be rich in cash and poor in profit because it holds money that should be working. Both problems arise in the same place: the short-term assets and liabilities that a business uses every day, collectively called working capital.
This topic opens the study of working capital management. It defines working capital and its elements, explains what managing it involves, sets out the objectives of liquidity and profitability and the other objectives that follow from them, and shows with numbers why the objectives conflict and how a manager balances them. The next topic covers the cash operating cycle, working capital ratios and overtrading.
Working capital questions make up a large part of the compulsory question in the paper: in May Diet, 2026, Question 1 (30 marks) and in November Diet, 2025, Question 2 (20 marks) both tested the investment in inventory, receivables and payables. The ideas in this topic are the framework for all of them. Read the bond market and technology in financial markets first.
In 30 seconds
Working capital is the finance needed to run an organisation’s daily operations, or the excess of current assets over current liabilities (net current assets). Its elements are inventory, receivables, payables, bank overdrafts, cash and short-term investment.
Working capital management manages all of them to reduce the risk of running out of cash while increasing the return on assets: current assets need funding so they are kept down, current liabilities give funding so they are increased, but extremes are unhealthy. The main objectives are liquidity and profitability, which conflict: over-investment lowers profit and under-investment threatens cash flow.
Poor management (overstocking, overtrading, shortage of cash) has caused many business failures.
What working capital is
Working capital is the finance an organisation needs to manage its daily operations. It can also be defined as the excess of current assets over current liabilities, that is, net current assets. To keep operating, an entity may:
- hold inventory;
- sell goods on credit, creating receivables;
- take credit from suppliers, creating payables;
- obtain short-term operating finance, a bank overdraft;
- hold cash to meet obligations as they fall due; and
- invest surplus cash for a short time for interest (short-term investment).
| Tola Foods Plc, ₦m | Amount |
|---|---|
| Inventory | 180 |
| Receivables | 240 |
| Cash | 30 |
| Short-term investment | 50 |
| Current assets | 500 |
| Trade payables | (210) |
| Bank overdraft | (90) |
| Current liabilities | (300) |
| Working capital (net current assets) | 200 |
Current assets are 1.67 times current liabilities (500 ÷ 300), and 1.07 times when inventory, the slowest asset to turn into cash, is excluded ((500 − 180) ÷ 300).
What managing working capital means
Managing working capital means managing all the elements, current assets and current liabilities, to reduce the risk of running out of cash while increasing the return on the assets. The current assets need funding, so the focus is on keeping them down; the current liabilities provide funding, so the focus is on increasing them. But taking either to the extreme is unhealthy, so a balance must be found.
Working capital management is the set of activities and strategies that keep the short-term assets and liabilities efficient, so that the company has enough liquidity to carry on its day-to-day operations smoothly. Good management can mean the difference between growth and stagnation, resilience and vulnerability. Its aim is that the investment in working capital is not excessive but is enough to support operations.
Liquidity management
Liquidity means having enough cash to meet all obligations when they fall due. Liquidity management aims at sufficient cash flows to pay liabilities when due and so avoid liquidity problems. The sources of liquidity include cash in the bank, short-term investments, cash sales, payments from receivables, the sale of inventory and overdraft facilities. The current assets must be sufficient to produce the cash flows needed when payments fall due. Extreme liquidity problems lead to insolvency.
Profitability management
Investment in inventory and receivables is necessary but earns no extra return by itself, and it ties up capital at a cost. Profitability management therefore means avoiding excessive investment in working capital. For example, receivables of ₦240m financed by an overdraft at 16% cost ₦38.4m a year in interest.
The objectives of working capital management
- Ensuring liquidity: enough cash flow to meet immediate and short-term obligations.
- Optimising profitability: balancing liquidity against the need to maximise the returns on current assets.
- Efficient use of assets: managing inventory and receivables to minimise waste and delay.
- Minimising financing costs: reducing the cost of capital and short-term borrowing by making the best use of funds.
- Managing risk: guarding against insolvency and financial distress caused by poor liquidity.
The conflict between liquidity and profit
Cash flow and profit are equally important. Profitable companies can fail if they run out of cash, and liquid companies can be unprofitable. Over-investment in working capital reduces profit and under-investment reduces cash flow, so the objectives conflict. Examples:
- Credit sales. increase profit but delay the cash.
A sale of ₦120m at a 40% margin earns ₦48m of profit at once, but if payment comes after 60 days and the company borrows at 15%, the delay costs ₦120m × 15% × 60 ÷ 365 = ₦2.96m of interest. - Paying for non-current assets reduces cash at once, while the effect on profit comes later through depreciation.
- Buying large inventory to earn a discount increases profit but reduces cash. Buying an extra ₦24m of goods to earn a 5% discount saves ₦1.2m, but if the money is borrowed at 15% for three months the interest is ₦0.9m, so the net gain is only ₦0.3m.
The ideas in more depth
Why profit does not equal cash
Profit counts a sale when it is made; cash arrives when the customer pays. A growing company that sells on credit and buys inventory ahead of sales may show rising profit and falling cash at the same time. If the cash runs out before the customers pay, the company fails even though it is profitable. This is the reason for the balancing of the two objectives.
Why working capital has a cost
Every naira in inventory or receivables must be funded, by owners or by lenders, and funds have a price. The aim is not to minimise working capital but to hold the amount whose benefit (sales support, service, security of supply) exceeds its financing cost.

Worked examples
Example 1: working capital. Inventory ₦180m, receivables ₦240m, cash ₦30m, short-term investment ₦50m; payables ₦210m, overdraft ₦90m. Required: working capital.
- Current assets.
180 + 240 + 30 + 50 = ₦500m. - Current liabilities.
210 + 90 = ₦300m, so working capital is ₦200m.
Example 2: the cost of credit sales. A sale of ₦120m is paid after 60 days; the company borrows at 15%. Required: the interest cost of the delay.
- Interest.
₦120m × 15% × 60 ÷ 365 = ₦2.96m.
Example 3: a bulk-purchase discount. Extra inventory of ₦24m earns a 5% discount; the money is borrowed at 15% for three months. Required: the net gain.
- Discount.
5% × ₦24m = ₦1.2m. - Interest.
₦24m × 15% × 3 ÷ 12 = ₦0.9m; net gain ₦0.3m.

Model answers
Show the model answer to Question 11
(a) Working capital is the finance needed for daily operations, or current assets less current liabilities (2). Elements: inventory, receivables, payables, overdraft, cash, short-term investment (2).
(b) Ensure liquidity; optimise profitability; use assets efficiently; minimise financing costs; manage the risk of insolvency (1 each, any four).
(c) Over-investment reduces profit and under-investment reduces cash flow (2).
Show the model answer to Question 12
(a) Current assets 150 + 210 + 20 = ₦380m; current liabilities 170 + 120 = ₦290m; working capital ₦90m (4).
(b) Receivables ₦150m; overdraft ₦120m − ₦60m = ₦60m; working capital is unchanged at ₦90m because an asset and a liability fall together (5).
(c)
- ₦60m × 16% = ₦9.6m a year saved (3).
- The liquidity position improves and financing cost falls without any loss of sales (3).
Show the model answer to Question 13
(a)
- Profit ₦200m − ₦140m = ₦60m (2).
- Interest ₦200m × 14% × 75 ÷ 365 = ₦5.75m (4).
(b) ₦60m − ₦5.75m = ₦54.25m (3).
(c) Discount 4% × ₦30m = ₦1.2m (2); interest ₦30m × 14% × 2 ÷ 12 = ₦0.7m (2); net gain ₦0.5m (1).
(d) Both transactions raise profit but tie up cash (2): the credit sale delays receipt by 75 days and the bulk purchase pays for inventory early (2). The company must be able to fund the gap, or the gain in profit may be lost through borrowing costs or a cash shortage (2).
