Cash Conversion Cycle: Receivables, Inventory, Payables
The short answer
The cash conversion cycle measures the days between paying for inputs and collecting cash from customers. It equals inventory days plus receivable days minus payable days [1]. A longer cycle means cash stays tied up in working capital for more days, which can strain cash flow even when profit looks healthy. Compare it with the company’s own history and sector.
What is the cash conversion cycle?
The cash conversion cycle is the number of days between disbursing cash and collecting cash for a unit of operations; it cannot be seen directly in the cash flow statement and must be derived from balance sheet data [1]. It shows how long a company is deprived of cash when it invests more in inventory to grow sales [1].
Think of three clocks running at once. Inventory days measure how long stock sits before it is sold. Receivable days measure how long customers take to pay. Payable days measure how long the company takes to pay its own suppliers. The first two lengthen the cycle; the third shortens it.
How are receivable, inventory and payable days calculated?
Each measure divides a balance sheet figure by an income statement figure and multiplies by the number of days in the period [1]. According to the standard formula, inventory days use average inventory over cost of goods sold, receivable days use average receivables over sales, and payable days use average payables over purchases [1].
Many readers use cost of sales in place of purchases, because purchases are rarely disclosed. State the choice, and use the same basis across years. This article covers the combined cycle; other Finworld guides look at receivable days and inventory turnover on their own, so the focus here is how the three fit together.
Inventory is normally carried at the lower of cost and net realisable value under the inventories standard [2]. Write-downs reduce the balance, so an inventory figure that falls because of a write-down is not the same as one that falls because stock was sold [2].
Worked example (hypothetical)
All figures are hypothetical. “Company A” is not a real company, and 365 days are used.
| Item (RM million, illustrative) | Company A |
|---|---|
| Revenue (illustrative) | 1,095 |
| Cost of sales (illustrative) | 730 |
| Average inventory (illustrative) | 120 |
| Average trade receivables (illustrative) | 225 |
| Average trade payables (illustrative) | 90 |
| Inventory days (illustrative) | 60 |
| Receivable days (illustrative) | 75 |
| Payable days (illustrative) | 45 |
| Cash conversion cycle (illustrative) | 90 days |
In this hypothetical illustration, Company A pays suppliers after 45 days but waits 135 days from stocking goods to being paid by customers. In the illustration, it funds the 90-day gap itself, from its own cash or from borrowings.
Why does a longer cycle strain cash flow?
A longer cycle strains cash flow because every extra day of the cycle is a day the company must finance. If sales grow while the cycle stays the same, working capital grows in proportion, and the cash needed grows too.
Hypothetical illustration: if Company A’s cycle stretched from 90 to 110 days with the same revenue, about RM60 million of extra cash would be tied up (20 days of RM1,095 million annual revenue over 365 days). That would show up as a negative working capital movement in the cash flow statement, and might push the company to borrow.
A shorter cycle is not always better. A negative cycle, where customers pay before suppliers are paid, is possible, but squeezing suppliers or chasing customers too hard may not be sustainable [1]. Judge the trend and the reasons, not one number.
Which Bursa sectors usually run long cycles?
Sectors that hold stock for long periods or bill customers in stages usually run longer cycles, while businesses paid at the point of sale usually run shorter ones. The pattern follows the business model.
| Business type | Typical pressure | Where to look |
|---|---|---|
| Manufacturers | Raw material and finished goods stock | Inventory note |
| Contractors | Slow certified payments, retention | Contract assets, receivables ageing |
| Traders and distributors | Stock plus supplier credit | Payables and inventory together |
Contractors deserve a special note. Contract assets and retention sums can behave like receivables but sit on separate lines, so a cycle based only on trade receivables can understate the true figure. The construction sector page and the industrial products and services page describe how these businesses operate.
Comparisons are most useful between companies with similar models. Comparing a contractor with a retailer says little. Cycle figures can be compared across companies in the same industry to assess cash management [1].
How does it link to operating cash flow?
The cash conversion cycle links to operating cash flow through the working capital movements in the cash flow statement. When the cycle lengthens, receivables and inventory rise and operating cash flow falls below profit; when it shortens, the reverse happens.
This is why the cycle sits between the income statement and the cash flow statement. Read it with our guide to reading the cash flow statement and the cash flow statement glossary entry.
Reading quarterly reports for cash flow and profitability is a basic part of company research [3]. Use the cycle as a question generator: what changed, why, and does the management discussion explain it?
Frequently asked questions
Is a negative cash conversion cycle good?
It can be, because customers pay before suppliers are paid, but it depends on whether the pattern is sustainable [1].
What is a good cash conversion cycle?
There is no universal figure. Compare a company with its own history and with similar businesses.
Can profit be high while the cycle strains cash?
Yes. Profit is recognised when sales are made, but cash only arrives when customers pay.
Where do I find the inputs in a Bursa report?
Use the income statement for revenue and cost of sales, and the balance sheet and notes for inventory, receivables and payables.
