Cash-to-Cash Cycle Calculator
Measures how many days it takes a company to convert inventory investments into cash from sales. Use it to benchmark working capital efficiency and spot cash flow bottlenecks in your supply chain.
About this calculator
The cash-to-cash cycle (C2C), also called the cash conversion cycle, measures the time elapsed between paying for raw materials and collecting cash from customers. The formula is: C2C = DIO + DSO − DPO, where DIO is Days Inventory Outstanding (how long inventory sits before sale), DSO is Days Sales Outstanding (how long it takes customers to pay), and DPO is Days Payable Outstanding (how long you take to pay suppliers). A lower C2C means your business converts resources to cash faster, requiring less working capital. Extending DPO (paying suppliers later) or shrinking DIO and DSO (selling faster and collecting sooner) all reduce the cycle. Negative C2C values — common in retail — mean you collect cash before you pay suppliers, a highly favorable position.
How to use
Suppose a manufacturer has DIO = 45 days, DSO = 30 days, and DPO = 20 days. Plug into the formula: C2C = 45 + 30 − 20 = 55 days. This means the company ties up working capital for 55 days between paying for inventory and receiving customer payment. To improve, the company could negotiate 30-day supplier terms (raising DPO to 30), which would reduce C2C to 45 days — freeing up 10 days' worth of cash. Enter your own DIO, DSO, and DPO values to instantly see your cycle length.
Frequently asked questions
What is a good cash-to-cash cycle time for a manufacturing business?
For manufacturers, a C2C of 30–60 days is generally considered healthy, though this varies significantly by industry. Capital-intensive industries with long production runs naturally have higher DIO and thus longer cycles. Benchmarking against industry peers is more meaningful than chasing a universal target. Companies like Apple have achieved negative C2C cycles by collecting customer payments before paying suppliers.
How does reducing Days Payable Outstanding affect the cash-to-cash cycle?
Reducing DPO (paying suppliers faster) actually increases your C2C cycle, which is unfavorable — you're spending cash sooner without a corresponding speedup in collections. Conversely, negotiating longer payment terms with suppliers raises DPO and shortens C2C. However, paying too slowly can damage supplier relationships or disqualify you from early-payment discounts. Balance is key.
Why is the cash-to-cash cycle important for supply chain management?
C2C directly ties supply chain performance to financial health. A long cycle signals excess inventory, slow collections, or weak supplier negotiating power — all of which drain cash and can create liquidity risk. Supply chain managers use C2C to prioritize improvement projects, such as lean inventory programs or tighter credit policies. Investors and lenders also monitor C2C as a signal of operational efficiency.
