# What Is Margin of Safety?

The margin of safety is the difference between an asset's estimated intrinsic value and its market price.

It provides a cushion against valuation errors and uncertainty.

Formula

Margin of Safety = (Intrinsic Value − Market Price) ÷ Intrinsic Value × 100

Example

Estimated intrinsic value = ₹1,000.

Market price = ₹750.

Margin of safety:

(1,000 − 750) ÷ 1,000 × 100 = 25%

NIFTY-Style Example

Suppose an investor estimates the intrinsic value of a hypothetical NIFTY stock at ₹2,000 and the market price is ₹1,500.

Margin of safety = 25%.

But the estimate is only as reliable as the assumptions behind it.

Why It Matters

Valuation depends on assumptions about:

•revenue growth,
•margins,
•interest rates,
•capital expenditure,
•terminal growth,
•competition, and
•future cash flows.

A discount to estimated value can provide a buffer when those assumptions prove imperfect.

Margin of Safety Is Not a Guarantee

A stock trading below estimated value is not automatically cheap.

If estimated value is ₹1,000 but the true value is ₹500, buying at ₹700 is still an overpayment.

Practical Checklist

Before relying on a margin of safety, ask:

1.Is the valuation method reasonable?
2.Are earnings and cash flows high quality?
3.Is debt manageable?
4.Are growth assumptions realistic?
5.Is the business facing structural deterioration?
6.Why is the market price below estimated value?

Final Thoughts

Margin of safety does not mean:

"Buy because the stock has fallen."

It means:

"Buy only when the price provides a meaningful cushion relative to a carefully considered estimate of value."
