The Cash Conversion Cycle

How to See Your Business in a Whole New Way

Most business owners check their bank balance to judge how things are going.

But your bank balance is a snapshot — it tells you where you are right now, not how well your business moves money through its system.

That’s where the Cash Conversion Cycle (CCC) comes in.

The CCC shows how long it takes to turn £1 spent on stock or production into £1 back in your bank account.

Once you understand it, you’ll never look at your cash flow the same way again.

The Cash Conversion Cycle measures the journey of cash through your business:

1. You spend money on stock, raw materials, or production.
2. You sell the product or service (often on credit).
3. You collect payment from your customers.

The CCC is the total time between spending the first pound and getting it back.

It’s made up of three parts:

• Days Inventory Outstanding (DIO): How long you hold stock before selling it.
• Days Sales Outstanding (DSO): How long it takes to collect payment.
• Days Payable Outstanding (DPO): How long you take to pay suppliers.

Formula: CCC = DIO + DSO – DPO.

Lower is better — a shorter cycle means your cash is working harder. A negative CCC is the holy grail for cash flow.

Here’s how to use it:

1. Calculate your CCC – Use:
   DIO = (Average Inventory ÷ Cost of Goods Sold) × 365
   DSO = (Average Accounts Receivable ÷ Revenue) × 365
   DPO = (Average Accounts Payable ÷ Cost of Goods Sold) × 365
   CCC = DIO + DSO – DPO
2. Identify bottlenecks – Is stock sitting too long? Are customers slow to pay? Are you paying suppliers too quickly?
3. Improve the moving parts – Reduce DIO, tighten credit control, extend DPO.
4. Monitor quarterly – Track your CCC over time and set improvement targets.

Example: An electronics distributor had:

• DIO: 78 days
• DSO: 52 days
• DPO: 30 days

CCC = 78 + 52 – 30 = 100 days

It took over 3 months to turn a £1 spent into £1 back.

We reduced DIO to 55 days, cut DSO to 39 days, and negotiated 45-day supplier terms.

Within 6 months, their CCC dropped to 49 days — freeing up hundreds of thousands in working capital.

The takeaway: The CCC is a powerful tool for managing working capital. It tells you exactly where your cash is tied up and how to release it.

Shortening your CCC means:

• Less reliance on overdrafts or loans.
• More cash for growth.
• Greater resilience in downturns.

Action steps:

1. Calculate your CCC.
2. Identify the biggest delay.
3. Take one action this month to improve it.
