How to use the Margin of Safety Calculator
Last reviewed September 14, 2026
What this calculator does
The engine calculates dollar value = intrinsic value - current price and margin of safety = dollar value / intrinsic value x 100.
Formula and method
The engine calculates dollar value = intrinsic value - current price and margin of safety = dollar value / intrinsic value x 100. It uses intrinsic value as the denominator, returns zero when intrinsic value is zero, and classifies the result at 30%, 15%, and zero percent thresholds.
Variables and inputs
Enter Current Price and Intrinsic Value per share or per asset unit. Both values use the same currency and valuation basis. The result shows percentage margin, dollar value gap, and a text interpretation; it does not calculate intrinsic value from financial statements.
Worked example
For a current price of $85 and estimated intrinsic value of $100, dollar value = 100 - 85 = $15. Margin of safety = 15/100 x 100 = 15%, which the engine labels a reasonable margin of safety at its threshold.
How to interpret the result
A positive result means the current price is below the entered intrinsic value by that fraction of intrinsic value. It is protection against valuation error only under the quality of the intrinsic-value estimate; it is not a guarantee against loss or a prediction of price direction.
Common mistakes to avoid
Use intrinsic value as the denominator, not current price, and keep both inputs on the same per-share or per-asset basis. Do not treat a model value as an objective fact or assume a larger percentage offsets every business, market, or liquidity risk.
Assumptions and limitations
The engine does not estimate intrinsic value, test cash-flow forecasts, discount rates, terminal values, debt, dilution, taxes, or market volatility. A small change in assumptions can move the percentage substantially, and a negative result simply indicates price above the entered value under this model.
