-7.8% margin of safety
As of 2026-10-08, the base-case DCF model estimates the intrinsic value of Merck & Co., Inc. (MRK) at $129.22 per share, compared with a market price of $139.35, a margin of safety of -7.8%. The base case assumes 3.5% annual free cash flow growth and a 10.0% discount rate.
Across the sensitivity grid the estimate spans $105.44 to $156.57. Intrinsic value is an estimate built on assumptions, not a fact. A higher discount rate or slower growth pushes the estimate down, while stronger cash flow growth lifts it.
How the DCF works · Recalculate with your own assumptions · What is intrinsic value?
At $139.35, MRK trades about 7.8% above the base-case intrinsic value estimate, a modest premium. By this model the price sits within a normal band, though faster growth than assumed would change the picture.
COMPETITIVE MOAT

Based on trailing twelve-month data, MRK shows a free cash flow per share of $6.50 and a ROIC of 5.6%, key inputs for stock valuation using the DCF method. The P/FCF ratio of 21.4x and FCF yield of 4.59% are important context metrics when evaluating MRK's stock valuation relative to peers.
Merck & Co., Inc. currently generates $6.50 in free cash flow per share. At the current price of $139.35, a DCF model would discount these cash flows at an appropriate WACC and apply a terminal growth rate to arrive at an intrinsic value. The result depends heavily on your growth and discount rate assumptions — a 1% change in WACC typically shifts the fair value estimate by 10-15%. In MiniValuator the model uses a single discount rate that you can edit directly, 10% by default, rather than a computed WACC.
MRK trades at a P/FCF ratio of 21.4x with a free cash flow yield of 4.59%. This P/FCF is in a moderate range. However, whether MRK is truly undervalued requires comparing the DCF intrinsic value to the current market price and evaluating whether the margin of safety is sufficient for your risk tolerance.
To perform a DCF valuation on Merck & Co., Inc.: (1) Start with the trailing free cash flow per share ($6.50) as the base, (2) project future FCF growth over 5-10 years based on Drug Manufacturers - General industry trends and company fundamentals, (3) apply a discount rate (WACC) reflecting MRK's risk profile — with a debt-to-equity of 1.29x, capital structure is an important factor, and (4) add a terminal value for cash flows beyond the projection period.
DCF (Discounted Cash Flow) estimates what a company is worth today based on its future cash generation. For Merck & Co., Inc., this means projecting how much free cash flow the company will produce over the next 5-10 years, shaped by Drug Manufacturers - General trends, then discounting those amounts to today's dollars. MRK's ROIC of 5.6% means the company's return on invested capital sits below the level that typically clears its cost of capital.
WACC (Weighted Average Cost of Capital) is the discount rate in a DCF model — it reflects the minimum return investors require. For MRK, with a debt-to-equity ratio of 1.29x, the capital structure directly influences WACC. A 1% increase in WACC typically reduces the intrinsic value by 10-15%. At an EV/EBITDA of 28.5x, the market's implied discount rate can be reverse-engineered for comparison. In MiniValuator you set this discount rate yourself as a single editable number, 10% by default, instead of computing a formal WACC.
DCF and P/E value MRK with different methods and assumptions, so the two conclusions can differ. Compare the P/E fair value.
