The Working Capital Metric Warren Buffett Would Use Over EBITDA
Key Points
- EBITDA can make a business look strong even when cash flow is strained.
- The Working Capital Cycle and Cash Conversion Cycle reveal the true speed of your internal cash engine.
- Slow collections, excess inventory, and early supplier payments trap cash inside operations.
- Shortening the cycle strengthens liquidity without taking on new debt.
- Buffett’s approach aligns with metrics tied to cash movement, not accounting summaries.
Executive Summary
A large number of executives still rely on EBITDA as a guide for business strength. That approach creates blind spots. With banks tightening and credit less available, depending on profit figures that ignore timing and cash needs puts a company at risk.
Your real advantage is the speed at which your business turns working capital into cash. That speed—often called Cash Velocity—shapes growth, stability, and resilience. The Working Capital Cycle (WCC) is the best window into that speed, and it offers a clearer view of financial health than EBITDA ever will.
This piece explains why the WCC belongs at the center of your strategy and how trapped cash inside operations can weaken your business long before anyone notices.
I. Why EBITDA Fails Executives
Buffett has long pointed out that EBITDA hides real costs and misses the timing of cash use. Many executives fall into the same trap: assuming strong earnings mean strong liquidity.
The core issue is simple:
- EBITDA shows a result from the past.
- Working Capital Cycle metrics show the current condition of your cash engine.
One is a scoreboard. The other is a live dashboard.
Your company gains value from the speed and reliability of its internal cash movement—not from an isolated earnings line.
II. The Working Capital Cycle: The Real Engine of Value
The WCC measures how long cash stays locked between paying vendors and receiving payment from customers. Any slowdown in that cycle restricts growth, increases dependence on lenders, and heightens stress across the business.
The Cash Conversion Cycle (CCC) sits within the WCC. It measures the total number of days it takes to turn outlaid cash into collected cash. A shorter cycle means:
- stronger liquidity
- smoother operations
- fewer surprises
- more flexibility during shifts in the market
A longer cycle creates pressure on payroll, vendor relationships, and strategic planning.
III. The Hidden Problem: Trapped Cash Inside Operations
Most companies have money stuck in places they rarely examine closely. That trapped cash weakens financial strength and pushes executives into expensive short-term solutions.
| WCC Issue | What’s Happening | Real Impact |
|---|---|---|
| High DSO (slow collections) | Customers delay payment. | Payroll and operating needs start to strain cash. Borrowing becomes common. |
| High DIO (slow inventory turnover) | Inventory sits without movement. | Cash stays tied up in goods that earn nothing. Items may lose value. |
| Low DPO (paying suppliers too quickly) | Money leaves the business faster than necessary. | Early-pay discounts go unused and margins shrink. |
The combined effect of these issues determines your Cash Velocity. Improve them, and you free money already inside your business. Ignore them, and the financial strain builds quietly until it becomes a crisis.
IV. Why Buffett’s Thinking Aligns With the WCC
Buffett focuses on a company’s ability to produce cash year after year. That ability depends on the speed of working capital—not the appearance of earnings on a spreadsheet.
A fast WCC reflects:
- reliable customers
- steady inventory movement
- strong operational timing
- disciplined management
A slow WCC signals deeper issues that EBITDA never reveals. This distinction explains why Buffett views working capital behavior as a core indicator of long-term strength.
V. How to Strengthen Your WCC and Improve Cash Velocity
Executives looking to improve cash flow without adding debt often find the quickest gains inside the WCC. Key steps include:
- Speed up receivables
Review billing accuracy, follow-up timing, and credit terms. Even minor changes create meaningful improvements. - Move inventory faster
Use aging reports to identify slow items. Adjust purchase patterns or reduce low-value SKUs. - Rebalance payables
Use full supplier terms. Reserve early payments for discount programs that add direct margin.
These adjustments unlock cash already earned without raising capital or increasing leverage.
