Cash Conversion Cycle Formula (CCC) Explained

The Cash Conversion Cycle (CCC) measures the time it takes for a business to convert its investments in inventory and accounts receivable into cash, minus the time it takes to pay its suppliers. It's a key indicator of liquidity and operational efficiency.

4 variables. Published Mar 12, 2026. Updated Mar 27, 2026. By AI Biz Hub.

Formula
Cash Conversion Cycle = Days Inventory Outstanding + Days Sales Outstanding - Days Payables Outstanding

Variables

CCC

Cash Conversion Cycle

The number of days cash is tied up between paying suppliers and collecting from customers. A lower or negative CCC means the business funds itself; a high one strains working capital.

DIO

Days Inventory Outstanding

Days Inventory Outstanding: the average number of days inventory sits before being sold. Lower means capital is not parked in stock.

DSO

Days Sales Outstanding

Days Sales Outstanding: the average number of days to collect cash after a sale. Lower means customers pay faster.

DPO

Days Payables Outstanding

Days Payables Outstanding: the average number of days the business takes to pay its suppliers. Higher (within terms) keeps cash longer and shortens the cycle.

Step by step

  1. 1

    Set the baseline case with the real calculator inputs.

    Dio = 38, Dso = 42, Dpo = 28, Monthly Cogs = 95,000

  2. 2

    Express all three components in days over the same period so they can be added and subtracted directly.

    Annual figures convert each ratio to a day count: for example DIO of 45, DSO of 40, DPO of 30 days.

  3. 3

    Apply the formula and read the first calculator outputs, not just the headline assumption.

    The calculator lands with cash conversion cycle at 52 and working capital tied at $164,667.

  4. 4

    Re-run after extending payables or tightening collections to see which lever shortens the cycle most for your business.

    Pushing DPO from 30 to 45 days cuts the cycle by 15 days with no change to sales.

Worked example

Cash Conversion Cycle sample case

Dio

38

Dso

42

Dpo

28

Monthly Cogs

95,000

Cash Conversion Cycle = Days Inventory Outstanding + Days Sales Outstanding - Days Payables Outstanding using dio 38, dso 42, dpo 28, monthly cogs 95,000.

The calculator lands with cash conversion cycle at 52 and working capital tied at $164,667.

Questions people ask next

What is the cash conversion cycle formula?

The cash conversion cycle equals Days Inventory Outstanding plus Days Sales Outstanding minus Days Payables Outstanding (CCC = DIO + DSO - DPO). It measures the number of days cash is tied up between paying suppliers and collecting from customers.

What are the three components of the cash conversion cycle?

The three components are Days Inventory Outstanding (DIO), the average days inventory sits before it sells; Days Sales Outstanding (DSO), the average days to collect cash after a sale; and Days Payables Outstanding (DPO), the average days the business takes to pay its suppliers. DIO and DSO are added because they tie up cash, while DPO is subtracted because delaying payment keeps cash longer.

What does the cash conversion cycle mean and why does it matter?

The cash conversion cycle measures how long it takes to turn investments in inventory and receivables into cash, minus the time taken to pay suppliers. It is a key indicator of liquidity and operational efficiency: a lower or negative CCC means the business funds itself, while a high one strains working capital.

How do you calculate the cash conversion cycle with an example?

Plug each component in days into DIO + DSO - DPO. Using DIO of 38, DSO of 42, and DPO of 28 days, the cycle works out to a cash conversion cycle of 52 days, with about $164,667 of working capital tied up at that level.

How can a business shorten its cash conversion cycle?

Re-run the formula after extending payables or tightening collections to see which lever helps most. For example, pushing DPO from 30 to 45 days cuts the cycle by 15 days with no change to sales, since holding cash longer (within terms) directly shortens the cycle.
