Part 2 — From Break-Even to Cash Burn

Why the Same Business Suddenly Needs Financing

In Part 1, we rebuilt break-even using cash logic instead of accounting shortcuts.

Now we follow the consequence.

State A vs State B Is Not a Storytelling Trick

Most analyses compare two “states” using annual averages.

This model does not.

Instead:

• changes occur monthly,
• cash gaps appear when they actually happen,
• borrowing is triggered by liquidity shortfalls, not by losses.

Cash problems don’t wait for year-end financial statements.

Why Did the Cash Cycle Change?

When the cash cycle increases, it must be explained.

There are only two real reasons.

Receivables Increase Because:

1. management intentionally extended credit to gain market share, or
2. customers delayed payments due to financial stress.

The same logic applies to:

• inventory accumulation,
• supplier terms,
• financing needs.

The model does not guess the reason. It forces the question.

Financing Cost Is a Result, Not an Assumption

Once working capital increases:

• cash deficits appear,
• borrowing becomes necessary,
• interest expense is generated mechanically.

This is critical:

Interest cost is not a management decision. It is the price of earlier decisions.

Why Averages Mislead

Using annual averages:

• smooths timing differences,
• hides peak financing needs,
• understates risk.

Monthly modeling:

• exposes liquidity pressure,
• shows when cash actually runs out,
• prevents “it works on paper” decisions.

Turning Break-Even into a Decision Engine

In this framework:

• nothing is fixed,
• the user adjusts:
• receivable days,
• inventory days,
• payable days,
• interest rates,
• unit costs,
• sales volume.

And observes immediately:

• financing needs,
• cash burn,
• break-even timing.

The goal is not prediction. The goal is understanding consequences.

Final Thought

Break-even is not a number. It is a path through time shaped by decisions.

If you only know where profit becomes zero, but not how cash behaves on the way there,

you are managing results instead of managing risk.
