Margin of Safety Calculator keeps the calculation anchored to values you can verify. That is especially helpful when you want to update the scenario without changing the underlying method.

What this calculator does

Margin of Safety Calculator measures how far the entered market price sits below or above the entered intrinsic value. It works from intrinsic value and market price. For Margin of Safety Calculator, that narrow input set is intentional: it lets you isolate the relationship being measured instead of blending in unstated forecasts.

How to use it

Fill in Intrinsic value and Market price, using values from the same scenario. Use one currency for all monetary fields in Margin of Safety Calculator; the currency selector formats the result and does not convert exchange rates. Before calculating, recheck Intrinsic value, Market price against the source numbers you intend to analyze.

How the calculation works

Margin of safety = (intrinsic value − market price) ÷ intrinsic value × 100%. Using the same relevant values and formula should reproduce the Margin of Safety Calculator result independently. For Margin of Safety Calculator, when the output is extreme, first confirm the form values and units rather than assuming the calculation represents the intended scenario.

Example

If intrinsic value is estimated at $80 and market price is $60, the margin of safety is 25%. For another Margin of Safety Calculator scenario, keep the same formula and replace only the displayed inputs you want to test.

How to interpret the result

A positive percentage means the market price is below the entered intrinsic value; a negative result means it is above. The number is only as sound as the intrinsic-value estimate behind it. For a clean comparison with Margin of Safety Calculator, keep the displayed input definitions and measurement basis consistent across scenarios.

Limitations and notes

The calculator does not determine intrinsic value or prove that a stock is undervalued. Valuation estimates can be wrong, business conditions can change, and a large numerical margin does not remove company, liquidity, or market risk. Recalculate Margin of Safety Calculator when the source values entered on the form change materially.
