Definition
Replacement cost valuation estimates what it would cost to build an equivalent business today. If market value is below replacement cost, the company may be undervalued. Tobin's Q ratio formalizes this concept. This method is most applicable to asset-heavy businesses like real estate, infrastructure, and manufacturing.
functions Formula
Tobin's Q = Market Value / Replacement Cost of Assets
lightbulb Example
A mining company has equipment worth $500M to replace, mineral rights worth $300M, and other assets of $200M. Total replacement cost = $1B. Market cap + debt = $750M. Tobin's Q = 0.75, suggesting undervaluation.

- Most useful for asset-heavy industries
- Tobin's Q below 1.0 may signal undervaluation
- Intangible assets are difficult to assign replacement cost
- Provides a floor value based on real-world costs
