Derived Results
Fill in the financial inputs to derive your CCC.
Formula
DSO measures how long it takes to collect from customers. DIO measures how long inventory sits before a sale. DPO measures how long you take to pay suppliers. Subtract DPO because supplier credit offsets the cash you've deployed.
A lower CCC means cash returns faster. A negative CCC means you're funded by supplier credit — a powerful position, but one that depends on maintaining sales volume.

Frequently Asked Questions
How accurate is this calculator?
It uses browser-side arithmetic for planning and estimation. Always confirm final numbers with your accountant or financial advisor for decisions with legal or tax impact.
What does a negative CCC mean?
A negative CCC means you collect cash from customers before paying suppliers — effectively funding operations with supplier credit. This is common in large retailers (Amazon, Walmart) and subscription software businesses. It's a strong position, but dependent on maintaining volume and payment terms.
How do I improve my CCC?
Three levers: (1) Reduce DSO by invoicing faster and offering early-payment discounts. (2) Reduce DIO with tighter inventory forecasting and faster turnover. (3) Increase DPO by negotiating longer payment terms with suppliers — without straining relationships.
What period should I use in the "From Financials" tab?
Use 365 for annual analysis (most common), ~90 for quarterly, or ~30 for monthly. Ensure all financial inputs (inventory, COGS, A/R, revenue, A/P) use the same period as the period length you enter.
Can I trust these results for financial reporting?
No — this is a planning and scenario tool. It produces estimates for internal analysis, not audited figures. For financial reporting, use verified data from your accounting system or advisor.
