What it means
Every operating business advances cash and waits to get it back. A bakery pays for flour on Monday, bakes on Tuesday, sells the bread for cash on Wednesday: a cycle of two days.
A shipbuilder pays for steel and wages for three years and receives the final payment on delivery: a cycle measured in years. The cash cycle time puts a number on the wait, and the number determines how much working capital the business must have and how sensitive its cash position is to growth and disruption.
The cycle can be mapped stage by stage. Cash leaves when suppliers are paid, which is some days after materials arrive if the supplier grants credit.
Materials wait in stores. Production converts them into finished goods over the manufacturing lead time.
Finished goods wait for sale. On sale, an invoice is raised and the customer takes the credit period, plus any delay, to pay.
Each stage has a duration that can be measured from the accounting records (inventory days, receivable days, payable days) or, more precisely, from the operational data (average time from goods receipt to issue, average production lead time, average time from dispatch to invoice, average time from invoice to receipt). The operational view often reveals delays the financial ratios hide: three days between dispatch and invoicing, or a week of finished goods waiting for a delivery slot.
The financial consequence is direct. Working capital needed is approximately the daily cash cost of operations multiplied by the cycle time.
A business spending $50,000 a day with a 60-day cycle needs about $3,000,000 in the cycle; cut the cycle to 45 days and $750,000 is released. Growth works the same way in reverse: every extra $50,000 of daily spending needs another 60 days' worth of funding.
The cycle also measures exposure. While cash is out, the business is at risk that the customer fails, the goods are damaged, prices move or the project is cancelled.
A long cycle concentrates that risk; a short one limits it. Businesses with very long cycles (construction, aerospace, shipbuilding) manage it with progress payments, deposits and milestone billing, which break the cycle into shorter segments, and with financing structures matched to it.
Improving cycle time means working on the stages: shorter supplier lead times and smaller, more frequent deliveries reduce raw material days; production scheduling and bottleneck management reduce work in progress; make-to-order or better forecasting reduces finished goods; same-day invoicing, deposits and disciplined collection reduce receivable days; negotiated terms and paying on the due date increase payable days. Because the stages belong to different functions, the improvement is a cross-functional programme, and the cycle time is the measure that keeps it honest, since an improvement in one stage that lengthens another shows up in the total.
In practice
Real-world examples.
Example
A grocery retailer has a cash cycle of about minus 15 days: it sells goods for cash before it pays the supplier.
Example
A custom furniture maker takes a 50% deposit, cutting its effective cash cycle from 90 days to about 45.
Example
A defence contractor with a three-year build negotiates monthly progress payments, reducing its cash cycle from years to about 45 days per stage.
Think of it
“Cash cycle time is how long your money takes a round trip through the business before returning.
Formula
Calculation
Cash Cycle Time (accounting basis) = Days inventory outstanding + Days sales outstanding minus Days payables outstanding
Cash Cycle Time (operational basis) = Days from supplier payment to customer receipt, measured on actual orders
Working Capital in the Cycle = Daily operating cash cost x Cash cycle time
Worked example. A maker of industrial pumps maps its cycle for a typical order:
- Day 0: castings and components ordered; they arrive on day 21 (supplier lead time)
- Day 51: supplier paid (30-day terms from receipt)
- Days 21 to 35: components in stores awaiting the production slot (14 days)
- Days 35 to 60: machining, assembly and testing (25 days); labour and overhead paid weekly through this period, averaging day 48
- Days 60 to 67: finished pump awaits collection and shipping (7 days)
- Day 67: dispatched; invoice raised on day 70 (invoicing is done twice a week)
- Day 70 + 45 days of payment terms + an average of 12 days late = day 127: cash received
Cash out: components on day 51, labour and overhead around day 48. Cash in: day 127. Cash cycle time on the components: 127 minus 51 = 76 days; on labour: 127 minus 48 = 79 days. Weighted by cost (components 60%, labour and overhead 40%): about 77 days.
Daily operating cash cost across all orders: $40,000. Working capital in the cycle: $40,000 x 77 = $3,080,000.
Improvement plan, stage by stage:
- Stores wait: schedule component arrival for the production slot, cutting 14 days to 4 (saves 10 days)
- Finished goods wait: book shipping when testing starts, cutting 7 days to 2 (saves 5)
- Invoicing lag: invoice on dispatch, cutting 3 days to 0 (saves 3)
- Late payment: pre-due-date confirmation calls and reminders, cutting 12 days to 4 (saves 8)
- Deposit: 20% with order on all orders over $50,000, which brings a fifth of the receipt forward to day 0 (reduces the weighted cycle by about 20% of the receivable period)
- Total reduction: 26 days from process changes, to 51 days, plus the deposit effect bringing the weighted cycle to about 44 days
Working capital after: $40,000 x 44 = $1,760,000. Released: $1,320,000. At the company's 8% cost of borrowing, that saves about $106,000 a year, and the business can now grow 40% before needing the working capital it had before.
The accounting ratios tell the same story more coarsely: DIO 46 (all inventory stages), DSO 57, DPO 30, CCC 73 days before; after the changes, DIO 31, DSO 45 (deposits reduce receivables), DPO 30, CCC 46.Case study
Seen in the real world.
A manufacturer of laboratory equipment had grown from $10,000,000 to $25,000,000 of sales in four years and had gone from a cash-positive to a permanently overdrawn position, which its owners attributed to the cost of growth. A consultant mapped the cash cycle on a sample of forty orders and found it averaged 142 days: supplier lead times of 8 weeks, a further 5 weeks in stores because purchasing bought in economic batches regardless of the schedule, 4 weeks of production, 2 weeks awaiting final inspection because the single inspector was a bottleneck, invoices raised at month end, and customers taking 60 days. The consultant's report reordered the picture: the growth had not caused the cash problem; the cycle had, and growth had merely multiplied it.
Over a year the company introduced scheduled purchasing tied to production slots, trained a second inspector, invoiced on dispatch, took deposits on orders over $25,000, and moved its standard terms from 60 to 30 days for new customers. The cycle fell to 78 days.
Working capital in the cycle fell from about $6,200,000 to $3,400,000, the overdraft was repaid, and the next $10,000,000 of growth required about half the funding the previous $10,000,000 had. The owners' remark was that they had spent four years borrowing to fund waiting.
Watch out
Common mistakes.
- Measuring the cycle only from the accounting ratios, which hide operational delays such as invoicing lags and stores waiting time.
- Attributing cash strain to growth without measuring the cycle. Growth multiplies the cycle; a long cycle is the underlying cause.
- Improving one stage in a way that lengthens another, such as buying in bulk for a discount that adds weeks of stores time.
Questions
People also ask.
How does cash cycle time differ from the cash conversion cycle?
Often they are the same calculation. Cash cycle time is sometimes used more broadly for the operational measure from first outlay to final receipt on actual orders, while the cash conversion cycle is the ratio-based version from the balance sheet.
Can the cycle be negative?
Yes, where customers pay before suppliers are paid: retailers with cash sales, businesses taking deposits, subscription businesses with annual prepayment.
What is the fastest way to shorten the cycle?
Usually invoicing on dispatch, taking deposits, and collecting on time, because these require no change to operations. Inventory and production improvements take longer but can be larger.
