The cash conversion cycle (CCC) measures how long cash is tied up in operations before it returns from customers, net of supplier financing. Controllers and CFOs use DIO, DSO, and DPO to benchmark liquidity and working capital efficiency against peers and prior periods.
How to use this calculator
- Enter days inventory outstanding (average days inventory is held).
- Enter days sales outstanding (average collection period).
- Enter days payables outstanding (average payment period to suppliers).
- Review cash conversion cycle, operating cycle, and efficiency interpretation.
Formula
Operating cycle = DIO + DSO. Cash conversion cycle = DIO + DSO − DPO. A lower CCC generally means faster cash recovery, though negative CCC can indicate strong supplier terms.
Example
DIO 45 + DSO 35 − DPO 30 = 50-day cash conversion cycle — cash is tied up for roughly 50 days from inventory purchase through collection.
Frequently asked questions
How do I calculate DIO, DSO, and DPO?
DIO ≈ (Average inventory ÷ COGS) × 365. DSO ≈ (Average receivables ÷ Revenue) × 365. DPO ≈ (Average payables ÷ COGS) × 365. Use consistent period averages.
What is a good cash conversion cycle?
It varies by industry. Retailers with fast turns may have low or negative CCC; manufacturers often run higher. Trend and peer comparison matter more than a single benchmark.
Can CCC be negative?
Yes. When DPO exceeds DIO + DSO, suppliers finance operations — common in some large retailers.
How does CCC relate to working capital?
CCC explains timing within the current asset and liability cycle. Pair with the Working Capital Calculator for balance-sheet liquidity context.
