TMUS DCF valuation, input by input
TickerWorth's fair value for T-Mobile US, Inc. (TMUS) is $174.63 a share, against the delayed market price of $159.10 (priced within our range of $106.38 – $245.01). We do not call it over- or undervalued from inside our range. It is a model estimate, and every input behind it is sourced below. This is an educational model, not a price target or a recommendation.
Read the full reasoning
One of the lenses behind that blended figure is a discounted-cash-flow model, which on its own values TMUS at about $245.01 per share. The rest of this page walks through that DCF — its assumptions, reverse-DCF and discount-rate sensitivity — because it is the auditable anchor of the blend.
The valuation discounts T-Mobile US, Inc.'s projected free cash flows at a weighted-average cost of capital (WACC) of 6.6%, with a long-run terminal growth rate of 2.5%. About 81% of the enterprise value comes from the terminal value — the portion beyond the explicit forecast window — which is typical for a stable, cash-generative business and a reminder that small changes in the discount rate or terminal growth assumption swing the intrinsic value meaningfully.
Running the DCF in reverse — solving for the growth the current price already assumes — the market is implying roughly 0.6% annual revenue growth for TMUS. Our base case instead compounds to about 6.6% a year over the same forecast, so the market is pricing in slower growth than our base case. The reverse-DCF is a quick sanity check: it reframes 'is this stock cheap?' as 'do I believe the growth the price requires?' rather than arguing over a single point estimate of fair value.
Sensitivity matters more than any single number. Across a reasonable band of discount-rate assumptions, TMUS's modeled DCF value ranges from about $132.82 to $708.45 per share. If that range still sits below today's price, the market is optimistic relative to the model across the whole band; if it brackets the price, the stock is roughly fairly valued on our assumptions. Use the interactive slider to see exactly where your own cost-of-capital view lands.
How to read this page: the DCF fair value is what T-Mobile US, Inc. would be worth if its cash flows grow as modeled and are discounted at the stated WACC. The assumptions table shows every input and its source; the reverse-DCF shows what the market believes; the sensitivity band shows how fragile the answer is. None of this is investment advice — it is a transparent, auditable framework for forming your own view of TMUS's intrinsic value. Figures update as new filings and prices come in.
