Primary hub
What it is
Working Capital Days is a cash conversion metric used in cash conversion and working capital reporting. It gives portfolio CFOs, sponsors, lenders, and working capital owners a consistent way to compare performance across periods, portfolio companies, lender packages, LP updates, or value creation plans. The useful version defines the formula, source system, reporting owner, cadence, threshold, and exception rule, then ties the output back to cash forecast, AR aging, AP aging, inventory ledger.1,2
How it works
Role in the workflow
Working Capital Days should make clear where a metric fits inside board cadence, KPI review, cash forecasting, integration, value creation initiatives, risk escalation, and exit preparation.
Owner and timing
The operating lead should know who prepares it, when it is reviewed, and what decision or handoff it supports.
Supporting evidence
The record should connect to board packs, KPI dashboards, budgets, variance commentary, initiative trackers, lender reports, and value creation plans rather than relying on memory or loose email context.
Stakeholder impact
The operating record should explain how it affects management teams, board members, lenders, investors, functional leaders, and integration owners, including any approval, funding, reporting, or operating consequence.
In Practice
Example: A sponsor reviews Working Capital Days during a weekly or monthly operating review, compares it with budget, prior period, and lender or investor thresholds, then records the owner and next action in the KPI pack.

Why It Matters
Working Capital Days matters because KPI drift can hide a portfolio issue until it reaches valuation, covenant compliance, liquidity planning, or LP reporting. A clean definition lets finance, operators, lenders, and investors debate the result instead of debating the math.1,2

SponsorBeast Take
SponsorBeast treats Working Capital Days as private capital operating vocabulary. The metric should be traceable from dashboard output to source record so a board member, lender, LP, or operating partner can reconstruct the calculation.
