How is the cash conversion cycle calculated?
The cash conversion cycle (CCC) measures the time, in days, between paying for raw materials or inventory and receiving cash from sales. It combines three key metrics that together show how efficiently a business manages its working capital.
CCC = Receivable Days + Inventory Days − Payable Days
Where:
Receivable Days (DSO) = days to collect from customers
Inventory Days (DIO) = days stock is held before sale
Payable Days (DPO) = days taken to pay suppliers
Receivable days represent how long customers take to pay. Longer receivable days tie up more cash in outstanding invoices.
Inventory days measure how long stock sits in the business before being sold. Higher inventory days mean more cash is locked in unsold goods.
Payable days reflect how long you take to pay your own suppliers. Longer payable days effectively provide free short-term financing from suppliers.
A negative CCC is the ideal scenario — it means the business receives cash from customers before it needs to pay suppliers, effectively operating with supplier-funded working capital.
Assumptions and caveats
- •This calculator uses summary-level day counts. For precise figures, use account-level data from your financial statements.
- •The CCC can vary significantly by industry. Retailers and supermarkets often have negative CCCs, while manufacturers may have longer cycles.
- •Seasonal fluctuations can distort average day counts. Consider using figures from a representative period.
- •Service businesses with no inventory can set inventory days to zero — the CCC then becomes the difference between receivable and payable days.
Frequently asked questions
The cash conversion cycle (CCC) measures how many days it takes for a business to convert its investment in inventory and other resources into cash from sales. It combines receivable days, inventory days, and payable days into a single metric. A shorter CCC means faster cash generation and better working capital efficiency.
A negative CCC is excellent — it means you receive cash from customers before you need to pay suppliers. A CCC of 0 to 30 days is considered good for most businesses. Between 30 and 60 days is moderate, while anything above 60 days suggests the business may face working capital strain. Ideal ranges vary significantly by industry.
You can shorten your CCC by reducing debtor days (collecting faster through credit control or invoice finance), reducing inventory days (holding less stock through better demand planning), or extending payable days (negotiating longer supplier terms). Each day removed from the cycle frees up cash for the business.
Lenders and invoice finance providers look at the CCC to understand a business's working capital efficiency. A long CCC may indicate the need for external funding to bridge the gap between paying suppliers and collecting from customers. Improving your CCC can reduce reliance on borrowing and strengthen your negotiating position with finance providers.
