# Cash Conversion Cycle Calculator

Calculate the cash conversion cycle (CCC) from DIO, DSO, and DPO. Measure how many days cash is tied up in your business operations.

## What this calculates

See how many days your cash is tied up between paying suppliers and collecting from customers. Enter your inventory, receivables, payables, COGS, and revenue to calculate the full cash conversion cycle with DIO, DSO, and DPO breakdowns.

## Inputs

- **Average Inventory** ($) — min 0 — Average inventory balance for the period.
- **Cost of Goods Sold (COGS)** ($) — min 0 — Total cost of goods sold for the period.
- **Average Accounts Receivable** ($) — min 0 — Average accounts receivable balance.
- **Net Credit Sales (Revenue)** ($) — min 0 — Total revenue or net credit sales for the period.
- **Average Accounts Payable** ($) — min 0 — Average accounts payable balance.

## Outputs

- **Days Inventory Outstanding (DIO)** — Average days to sell inventory.
- **Days Sales Outstanding (DSO)** — Average days to collect payment after a sale.
- **Days Payable Outstanding (DPO)** — Average days to pay suppliers.
- **Cash Conversion Cycle** — Total days cash is tied up in operations (DIO + DSO - DPO).
- **Efficiency Assessment** — formatted as text — How efficiently the business manages its cash cycle.

## Details

The cash conversion cycle (CCC) measures the number of days it takes for a company to convert its investments in inventory and other resources into cash from sales. The formula is: CCC = DIO + DSO - DPO.

- **DIO (Days Inventory Outstanding):** How long inventory sits before being sold. (Average Inventory / COGS) x 365.
- **DSO (Days Sales Outstanding):** How long customers take to pay. (Average AR / Revenue) x 365.
- **DPO (Days Payable Outstanding):** How long you take to pay suppliers. (Average AP / COGS) x 365.

For example, if DIO is 91 days, DSO is 37 days, and DPO is 46 days, the CCC is 91 + 37 - 46 = 82 days. That means 82 days pass between when you pay for inventory and when you collect cash from selling it.

## Why CCC Matters

A shorter CCC means the business generates cash faster, reducing the need for external financing. Amazon famously operates with a negative CCC (around -30 days), meaning it collects from customers before paying suppliers. This is a massive competitive advantage that funds growth without borrowing.

To improve your CCC, focus on the component with the most room for improvement: sell inventory faster (reduce DIO), collect from customers sooner (reduce DSO), or negotiate longer payment terms with suppliers (increase DPO).

## Frequently Asked Questions

**Q: What is a good cash conversion cycle?**

A: It varies by industry. Grocery stores might have a CCC of 5-10 days, while manufacturers might be 60-90 days. A negative CCC (like Amazon's) means you collect cash before paying suppliers, which is ideal. The best approach is to compare your CCC to direct competitors and track whether it is improving or worsening over time.

**Q: Can the cash conversion cycle be negative?**

A: Yes, and it is a good thing. A negative CCC means the company receives cash from customers before it needs to pay suppliers. This is common in businesses with strong bargaining power over suppliers and immediate customer payments, like Amazon, Dell (historically), and many subscription businesses. It essentially means suppliers are financing the company's operations.

**Q: How does CCC differ from the operating cycle?**

A: The operating cycle is DIO + DSO -- the time from buying inventory to collecting cash. The CCC subtracts DPO because supplier credit offsets part of the cash requirement. If your operating cycle is 120 days but suppliers give you 45 days to pay, your CCC is 75 days. The CCC gives a more realistic picture of actual cash needs.

**Q: Which component of CCC should I improve first?**

A: Focus on the component farthest from industry benchmarks. If your DIO is 90 days but competitors average 50, inventory management is the priority. If DSO is 60 days on Net 30 terms, collection processes need work. Increasing DPO is tempting but be careful -- paying too slowly can damage supplier relationships and lose early payment discounts.
