We are profitable—why does the bank say we need a bigger overdraft?
Profit timing and cash timing differ. Calculate CCC. At 49 days on EUR 2M revenue, growth consumes cash before P&L profit arrives.
Library / Financial Control / Cash Conversion Cycle
Cash Conversion Cycle: plain-English definition, formula, worked example, how to interpret the result, peer-based benchmark guidance, common mistakes, and management actions in the ZBI Business Control Library.
Cash conversion cycle is how many days your money is stuck in stock and receivables before suppliers get paid. CCC = DIO + DSO − DPO. I use it in the monthly working-capital review because two plants can both show profit on the P&L while one needs EUR 200,000 more overdraft to fund the same growth. A EUR 2M manufacturer holding six weeks of inventory, collecting in five, and paying suppliers in four has a different cash profile than a distributor with the legs reversed—even when EBITDA looks similar.
Growth eats cash when CCC is long. Adding EUR 500,000 revenue with a 60-day CCC can require EUR 80,000 or more in extra working capital before you see profit in the bank. Ignore CCC and you approve a big customer order with 90-day payment terms while production builds six weeks of WIP—you fund their float from your overdraft. Suppliers feel it when you stretch DPO without agreement and they deprioritise your deliveries. The plant feels it when finance cuts stock purchases to preserve cash and production starves for components.
CCC = DIO + DSO − DPO
DIO — average inventory ÷ COGS × days in period.
DSO — receivables ÷ revenue × days in period.
DPO — payables ÷ COGS (or purchases) × days in period.
Excel: =B2+B3-B4 with each leg on its own row.
Velebit Plastika d.o.o., a EUR 2M packaging manufacturer in Karlovac, calculates March: DIO 45 days from average inventory EUR 150,000 and monthly COGS EUR 100,000; DSO 32 days; DPO 28 days. CCC = 45 + 32 − 28 = 49 days. Last year's average was 42 days—the slip is mostly DIO after a safety-stock increase on imported resin. The owner models cash need for 15% sales growth and renegotiates supplier terms toward 35 days DPO while cutting two slow-moving SKU families.
CCC is a timeline for cash, not a profit score.
Retail grocers often run negative CCC; capital-heavy manufacturers run positive. Compare to your quarterly trend and to peers with similar production length in annual reports—not to an unrelated sector headline. A five-day improvement versus last year beats matching an industry average that ignores your terms and seasonality.
Profit timing and cash timing differ. Calculate CCC. At 49 days on EUR 2M revenue, growth consumes cash before P&L profit arrives.
Fix the leg that moved most versus your 12-month baseline. For manufacturers, DIO or DSO usually beats squeezing suppliers on DPO.
Only if you have headroom or can shorten DIO. Otherwise you fund the customer's float from your line.
Use one consistent basis month to month; most management packs exclude VAT from trade balances.
Monthly normally; weekly when overdraft utilisation exceeds 80% or a large order changes terms.
CCC shows how long cash stays locked in operations before suppliers are paid. Manage each leg with a named owner and compare trends to your growth plan—not generic industry CCC alone.
