As of 2026-08-21, the base-case DCF model estimates the intrinsic value of T-Mobile US, Inc. (TMUS) at $199.43 per share, compared with a market price of $183.04, a margin of safety of +8.2%. The base case assumes 4.1% annual free cash flow growth and a 10.0% discount rate.
Across the sensitivity grid the estimate spans $153.79 to $252.51. 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 $183.04, TMUS trades about 8.2% below the base-case intrinsic value estimate. That is a real discount, but it stays short of the 30% margin of safety required before calling a stock undervalued.
COMPETITIVE MOAT
↑Extensive 5G Network Footprint
T-Mobile boasts a leading 5G network, offering a significant competitive advantage in speed and coverage. This attracts and retains customers seeking superior mobile experiences.
↑Un-carrier Brand Loyalty
The 'Un-carrier' brand aggressively challenges industry norms, fostering strong customer loyalty and a perception of value. This differentiation makes switching less appealing.
↑Scale and Spectrum Holdings
Significant spectrum holdings and operational scale provide T-Mobile with cost efficiencies and the capacity to deliver advanced services. This allows for competitive pricing and network investment.
INVESTMENT RISKS
↓Regulatory Scrutiny and Policy Changes
The telecommunications sector is heavily regulated. Changes in government policy, spectrum allocation, or antitrust enforcement could negatively impact T-Mobile's operations and profitability.
↓Technological Obsolescence and Disruption
Rapid advancements in technology, such as new wireless standards or alternative communication methods, could render T-Mobile's current infrastructure and services less competitive. Staying ahead requires constant innovation and investment.
↓Execution Risk on Strategic Initiatives
T-Mobile's success relies on effectively executing its growth strategies, including network expansion and customer acquisition. Any missteps or failures in these areas could hinder performance and shareholder value.

On a trailing twelve-month basis, TMUS generates free cash flow per share of $14.19 alongside a ROIC of 7.1%, both central inputs for a DCF valuation. Its P/FCF ratio of 12.8x and FCF yield of 7.82% then frame how TMUS is priced against peers on a cash flow basis.
T-Mobile US, Inc. currently generates $14.19 in free cash flow per share. At the current price of $183.04, 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.
TMUS trades at a P/FCF ratio of 12.8x with a free cash flow yield of 7.82%. A low P/FCF means investors are paying less per dollar of free cash flow; whether that is cheap depends on the company's growth, cyclicality, and capital intensity. However, whether TMUS 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 T-Mobile US, Inc.: (1) Start with the trailing free cash flow per share ($14.19) as the base, (2) project future FCF growth over 5-10 years based on Telecommunications Services industry trends and company fundamentals, (3) apply a discount rate (WACC) reflecting TMUS's risk profile — with a debt-to-equity of 2.06x, 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 T-Mobile US, Inc., this means projecting how much free cash flow the company will produce over the next 5-10 years, shaped by Telecommunications Services trends, then discounting those amounts to today's dollars. TMUS's ROIC of 7.1% 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 TMUS, with a debt-to-equity ratio of 2.06x, the capital structure directly influences WACC. A 1% increase in WACC typically reduces the intrinsic value by 10-15%. At an EV/EBITDA of 10.9x, 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 TMUS with different methods and assumptions, so the two conclusions can differ. Compare the P/E fair value.
