Is margin for error an underrated driver of business wealth?
We commonly misunderstand the concept of business risk as relating to leverage or volatility. Or scenarios like whether a business uses debt or equity. But that’s not how risk is measured at all.
Risk is measured in margin for error, access to liquidity, and corporate flexibility.
We can use this misunderstanding of risk to help explain why some businesses survive downturns and mistakes, while others – even highly profitable ones – do not.
Risk rarely shows up in the spreadsheet
Business plans tend to assume nothing and nobody will toss a wrench in your perfect conditions. Sure, if customers behave as expected, costs remain controllable, capital markets stay open, and growth unfolds according to plan, you’ll be on the road to creating a fortune.
Of course, wealth isn’t destroyed under “perfect conditions.” It’s destroyed when the dangerous assumption that those conditions will be perfect forever is proven wrong.
Margin for error helps determine whether a business can absorb:
- Cost overruns
- Pricing mistakes
- Demand slowdowns
- Capital market tightening
- Strategic missteps (yes, even by good leaders)
Businesses that don’t allow for this margin of error may look impressive in steady-state conditions. But they unravel in record time when stress appears. Cash flow gives your margin for error time. Of all the assets a business has under stress perhaps the most valuable asset any business has in times of high stress is time.
Time to:
- Adjust pricing
- Reduce costs
- Reallocate capital
- Refinance obligations
- Change strategy
And time is created by cash flow.
Businesses with strong current cash yields can self-fund corrections, giving them a wider margin for error than those who must rely on external capital (a resource rarely available when it’s needed most).
Margin for error as a competitive advantage
While I’m sure it’s clear by now that margin for error is a great defense, I can’t understate its role as an offense, either.
Businesses with liquidity and flexibility can:
- Invest when competitors are forced to retreat
- Acquire assets at distressed prices
- Retain talent during downturns
- Raise capital on better terms
This is why some companies grow stronger after periods of stress, while others permanently impair shareholder value.
Investors intuitively understand this and they reward businesses that demonstrate resilience with higher confidence, better access to capital, and long-term support – even when short-term returns fluctuate.
Designing a business with margin for error in mind
Unfortunately, margin for error doesn’t appear on its own. You need to embed it through your business model decisions.
As a leader, you decide:
How rigid or restrictive are capital sources?
How much fixed investment do you require?
How thin are operating margins allowed to become?
How much cash must be retained versus distributed?
Using large amounts of Other People’s Money can work if there is sufficient free cash flow and margin for error. But OPM often comes with strings attached (such as covenants, restrictions, or loss of flexibility) that impose real opportunity costs when conditions change. But the issue isn’t whether a business uses debt or equity, it’s whether the business can still function when reality deviates from the “perfect conditions” plan.
Enduring business wealth using your margin for error
The most consequential leadership decisions aren’t made when conditions are favorable. They’re made when revenues disappoint, capital tightens, strategies fail, and unexpected shocks occur. Businesses that combine strong cash generation, flexible capital structures, and manageable fixed commitments give leaders room to make good decisions under pressure.
A thoughtfully designed margin for error (made with the assumption that conditions will not be perfect forever) allows leaders to respond intentionally rather than react defensively. Over time, that margin for error becomes one of the most powerful drivers of enduring business wealth.
