Cash Conversion Cycle Calculator
How many days your cash spends trapped in operations.
Cash conversion cycle
Estimates for planning only, not financial advice.
The cash conversion cycle tells you how long each dollar stays locked in your operations before returning as cash in the bank. Add the days inventory sits (DIO) to the days customers take to pay (DSO), then subtract the days you take to pay suppliers (DPO). With the defaults, $74,000 of inventory on $600,000 of COGS is 45 days, $82,000 of receivables on $1 million of revenue is 30 days, and $41,000 of payables is 25 days: a 50-day cycle. Every day you shave off frees about $1,644 of working capital at this scale.
How to Use This Calculator
Enter annual revenue and cost of goods sold, then your average balances for inventory, receivables, and payables. Use averages across the year, not year-end snapshots, because period-end balances can be misleading. The calculator derives DIO, DSO, and DPO, combines them into the CCC, and translates the cycle into trapped working capital dollars. Run it quarterly and watch each component, not just the total.
Enter revenue, COGS, and average balances. Pull the averages from monthly balance sheets if you have them.
Read DIO, DSO, and DPO separately. The longest leg is your biggest opportunity.
Convert days to dollars: each CCC day is worth COGS/365 in freed cash. Target the cheapest lever first, usually collections.
The CCC Formulas
Each component has an owner: purchasing owns DIO, sales and collections own DSO, and procurement owns DPO. That is why the CCC is a management tool, not just a finance metric: it assigns the working-capital problem to the departments that can fix it. The trapped-cash line converts the abstract day count into the number executives act on. A 10-day improvement on $600,000 of COGS is $16,438 of freed cash, found without selling anything new.
Worked Example
A distributor does $1,000,000 in revenue with $600,000 of COGS. Average inventory of $74,000 gives DIO of (74,000/600,000) x 365 = 45 days. Receivables of $82,000 give DSO of (82,000/1,000,000) x 365 = 30 days. Payables of $41,000 give DPO of (41,000/600,000) x 365 = 25 days. CCC = 45 + 30 - 25 = 50 days. Trapped working capital is 50/365 x $600,000 = $82,192. If they tighten collections to a 20-day DSO, the CCC drops to 40 days and frees $16,438. If they also negotiate supplier terms from 25 to 35 days DPO, the CCC hits 30 days and frees another $16,438.
Benchmarks by Business Model
| Business model | Typical CCC | Why |
|---|---|---|
| Software / SaaS | 0 to 20 days | No inventory, upfront billing |
| Retail | Negative to 30 days | Fast turns, supplier funding |
| Distribution | 40 to 80 days | Inventory plus receivables |
| Manufacturing | 60 to 120 days | Long production and sales cycles |
Your trend matters more than the absolute number: a CCC lengthening 5 days a year for three years means working capital is quietly consuming your growth. Attack the longest leg first, but respect the trade-offs: squeezing DPO by paying late burns supplier relationships, and slashing inventory risks stockouts. The sustainable wins are better forecasting (DIO), disciplined collections (DSO), and negotiated terms (DPO).

Frequently Asked Questions
What is the cash conversion cycle?
The cash conversion cycle (CCC) measures how many days your cash is tied up in operations: from paying for inventory to collecting from customers. CCC = days inventory outstanding + days sales outstanding - days payable outstanding. A 50-day CCC means each dollar you spend takes 50 days to come back as collected cash. Shorter is better: it means less working capital trapped in the business.
What is the cash conversion cycle formula?
CCC = DIO + DSO - DPO. Days inventory outstanding (DIO) = (average inventory / COGS) x 365. Days sales outstanding (DSO) = (accounts receivable / revenue) x 365. Days payable outstanding (DPO) = (accounts payable / COGS) x 365. With DIO 45, DSO 30, and DPO 25, the CCC is 50 days.
What is a good cash conversion cycle?
It depends on the business model. Retailers like Amazon run negative CCCs, collecting from customers before paying suppliers, which means suppliers fund their growth. Manufacturers often run 60 to 120 days. Software companies can run near zero with no inventory and upfront billing. Compare against your industry and your own trend: a CCC drifting longer year over year is an early warning of working-capital trouble.
Can the cash conversion cycle be negative?
Yes, and it is a superpower. A negative CCC means you collect cash from customers before you pay suppliers: DIO + DSO is smaller than DPO. Dell and Amazon famously ran negative cycles, effectively getting interest-free loans from their supply chains. It requires market power over suppliers and fast inventory turns, so it is common in retail and rare in manufacturing.
How do I reduce my cash conversion cycle?
Three levers: sell inventory faster (tighter purchasing, better forecasting), collect receivables faster (shorter terms, early-pay discounts, stricter follow-up), and pay suppliers slower (negotiate longer terms without damaging relationships). Each day shaved off the CCC frees roughly one day of COGS in cash. A $3.65 million COGS business frees $10,000 per day of improvement.
What is days sales outstanding (DSO)?
DSO is the average number of days it takes to collect payment after a sale: (accounts receivable / annual revenue) x 365. A DSO of 30 on net-30 terms is perfect execution; a DSO of 55 on net-30 terms means customers pay 25 days late on average. Rising DSO is often the first sign of customer distress or a sloppy collections process, and it directly lengthens the CCC.
What is days payable outstanding (DPO)?
DPO is how long you take to pay suppliers: (accounts payable / COGS) x 365. Stretching DPO shortens the CCC because suppliers fund more of your cycle. But there is a relationship cost: paying late damages supplier goodwill, forfeits early-pay discounts (often 2% for 10 days early, an excellent return), and can trigger supply disruptions. Negotiate longer terms openly rather than just paying late.
How does CCC relate to working capital?
The CCC determines how much working capital the business needs to fund itself. Roughly: working capital need = CCC/365 x annual COGS. A 50-day CCC on $3.65 million of COGS ties up $500,000. Halve the CCC and you free $250,000 of cash without selling a dollar more. This is why working-capital improvement is often the cheapest "financing" available.
Why is CCC more useful than the current ratio?
The current ratio is a static snapshot of assets versus liabilities; the CCC measures the speed of the machine. A company can have a healthy current ratio and a terrible CCC if inventory is obsolete or receivables are uncollectible. Lenders and acquirers study the CCC trend because it reveals operational quality that balance-sheet ratios hide.
How often should I calculate CCC?
Quarterly at minimum, monthly if working capital is tight. Use average balances (beginning plus end divided by two) rather than period-end snapshots, which can be gamed by timing. Track the three components separately, because a stable CCC can hide DIO improving while DSO deteriorates, and you want to know which lever moved.
