Cash Conversion Cycle Calculator
How many days between paying a supplier and getting cash from a customer, the lifeblood metric for bootstrapped D2C.
About this tool
Cash Conversion Cycle (CCC) = Days Inventory + Days Sales Outstanding − Days Payable Outstanding. Negative CCC = customers pay you before you pay suppliers. Long positive CCC = you finance every cycle yourself. Calculate it across your operating cycle to see how much working capital you actually need.
Why D2C founders ignore this and shouldn't
Most bootstrapped D2C brands can run profitable on paper while starving for cash. CCC is the lens that exposes this: even at 30% net margin, if your CCC is 120 days and you're growing, every month requires more working capital than the last to fund inventory you haven't yet sold.
The DPO conversation
The biggest unlock is usually supplier terms. Once you're past your first few POs, ask for Net 30 or Net 60. Most suppliers will accept Net 30 immediately at moderate volume; Net 60 once you've shown consistent ordering. That alone can drop CCC by 30–60 days.
