Listener Q&A: Should You Adjust Your WACC for Inflation?

What It Covers

A listener asks whether inflation should be factored into WACC calculations when valuing companies. The episode explains how the Federal Reserve's interest rate tools connect to inflation, how businesses with pricing power survive inflationary periods, and how to apply inflation consistently across DCF models without double-counting.

Key Questions Answered

• •WACC and Inflation Application: Apply inflation uniformly across all WACC calculations rather than adjusting company by company. When inflation rises, interest rates follow, which raises the discount rate and lowers all valuations equally. This consistent approach prevents distorted comparisons between companies and keeps the math from producing misleading results across your portfolio.
• •Terminal Growth Rate Anchoring: Tie the terminal growth rate to the 10-year treasury rate rather than setting it independently. When interest rates rise, both the terminal growth rate and WACC rise together, preventing the DCF math from producing extreme or obviously incorrect valuations. Damodaran's free YouTube courses cover this methodology in depth.
• •Pricing Power as Inflation Defense: Companies with structural pricing power — such as Visa, Mastercard, auto insurers, and home builders — outperform during high inflation because revenues naturally scale with economic growth. Capital-light businesses like See's Candy compound this advantage: lower cost sensitivity plus pricing power means margins hold while competitors compress.
• •Deflation vs. Inflation Risk: Deflation, where currency gains value and prices fall, triggers a spending freeze as consumers wait for lower prices, collapsing GDP and corporate revenues simultaneously. The Fed targets 2–3% inflation specifically to prevent this spiral. Investors should treat any deflationary environment as a higher systemic risk signal than moderate inflation.
• •DCF Without Full Mastery: Price-to-earnings ratios combined with growth analysis deliver roughly 90% of the analytical value a full DCF provides. The hosts did not learn DCF modeling until three years into running the podcast. Beginners should prioritize understanding business quality and moat before attempting terminal value calculations, which took months of focused study to apply competently.
