Cash Conversion Cycle (CCC) Calculator
From DIO, DSO and DPO, compute the cash conversion cycle: how many days cash is tied up from buying to collecting.
Input Data
Results
At a glance:CCC = DIO + DSO - DPO. DIO = average days inventory is held; DSO = average days to collect from customers; DPO = average days you take to pay suppliers. It is the net days your cash is tied up from buying inputs to collecting sales. Shorter (or negative) is better — cash turns faster and less external funding is needed. Example: DIO 30 + DSO 45 - DPO 40 = 35 days. Levers: lower DIO (faster inventory), lower DSO (faster collection), raise DPO (slower payment) — but don't strain suppliers. WARNING: A snapshot ratio; ignores seasonality and one-offs. For HK SMEs, a short CCC is vital for cash. Education, not advice.
Formula
CCC = DSO + DIO − DPO.
$$\text{CCC} = \text{DSO} + \text{DIO} - \text{DPO}$$How to Use
- Enter DIO, DSO and DPO (in days).

FAQ
What does the CCC mean in plain terms?
It is the number of days from when you pay for goods to when you collect cash from the sale. DIO = how long stock sits; DSO = how long customers take to pay; DPO = how long you delay paying suppliers. CCC = DIO + DSO - DPO is the net days your own cash is stuck in the cycle. Shorter means faster cash recovery and less need for borrowing.
Why is a negative CCC good?
A negative CCC means you collect from customers before you must pay suppliers (DSO + DIO < DPO). You run the business partly on suppliers' money — effectively free financing. Many retailers and fast-turn models achieve this. It is a sign of strong working-capital efficiency.
How do I shorten the CCC?
Three levers: (1) Lower DIO — better inventory management, faster turnover, less dead stock. (2) Lower DSO — faster invoicing, stricter credit terms, active collection (see the A/R days and average collection period calculators). (3) Raise DPO — negotiate longer supplier terms, but without harming the relationship or incurring late fees. Improving any of the three shortens the cycle.
Does a short CCC always mean healthy?
Mostly yes for cash efficiency, but not absolutely. Too-low DIO risks stockouts and lost sales; too-low DSO may mean overly strict credit that hurts growth; too-high DPO can sour supplier ties and lose early-payment discounts. Balance the three with the business strategy; the CCC is a tool, not a target to minimise at all costs.
Any Hong Kong notes?
Hong Kong SMEs often run on tight cash, so monitoring the CCC helps avoid liquidity gaps. Pair it with receivables/payables turnover and the working-capital calculator; the HKPC and HKTDC offer SME support. The CCC is a ratio, not a cash-flow forecast — use the cash-flow statement for actual liquidity. Education, not advice.
