How it works
The cash conversion cycle (CCC) measures the number of days between when you pay cash to suppliers and when you receive cash from customers. It is the single most complete metric of operating cash efficiency because it combines three sub-metrics: days inventory outstanding (how long stock sits), days sales outstanding (how long customers take to pay), and days payable outstanding (how long you take to pay suppliers). The formula is CCC = DIO + DSO − DPO. A CCC of 50 days means your cash is tied up in operations for 50 days between paying for materials and collecting from sales. A negative CCC — which companies like Amazon achieve — means you collect from customers before you pay suppliers, effectively running the business on other people 's money. The calculator converts the CCC into a dollar figure by multiplying the difference from industry average by your daily revenue, showing exactly how much working capital you could free by optimizing each component.
Formula
CCC = DIO + DSO − DPO | Cash freed = (Industry CCC − Your CCC) × Revenue ÷ 365 | Daily cash need = Revenue ÷ 365 × CCC ÷ 365
Tips
- A negative CCC is the holy grail — collect fast, pay slow, and grow without external financing.
- Improving any one component (faster collections, slower payments, quicker inventory turnover) reduces CCC.
- Seasonal businesses should calculate CCC for the same quarter year-over-year.
- Track CCC monthly — a rising trend signals deteriorating cash efficiency before it becomes a crisis.
Frequently asked questions
- What is a good cash conversion cycle?
- A lower CCC is better. Negative CCC (collecting before paying) is the gold standard — companies like Dell and Amazon achieve this. For most businesses, CCC under 30 days is strong. The key is your trend: a shrinking CCC over time means improving cash efficiency.
- How do I calculate the cash conversion cycle?
- CCC = Days Inventory Outstanding + Days Sales Outstanding − Days Payable Outstanding. DIO = 365 ÷ Inventory Turnover, DSO = 365 ÷ AR Turnover, DPO = 365 ÷ AP Turnover. Or simply count the days from supplier payment to customer collection across a sample transaction.
- Can CCC be negative?
- Yes, and it is often a sign of strong business economics. A negative CCC means you collect revenue before paying suppliers — effectively getting interest-free financing from your supply chain. Amazon is the classic example: it collects from customers immediately but pays suppliers on 60–90 day terms.
- How does CCC affect business growth?
- A high CCC requires more working capital to fund each dollar of growth. If your CCC is 60 days and revenue doubles, you need roughly twice the cash to bridge the gap. A low or negative CCC means you can grow with less external financing because operations generate their own cash.
