At today's price, Alphabet's stock is pricing in about 26% annual free-cash-flow growth for the next ten years, using trailing-12-month FCF. Over the past five years, the company's actual FCF growth averaged just 2.3% a year, and revenue grew 11.8% a year.
At its current price, GOOGL implies ~26% annual FCF growth for the next 10 years, using trailing-12-month FCF at a 10% discount rate.
Alphabet's actual 5-year FCF growth has averaged just 2.3% a year; revenue grew 11.8% a year.
Required growth vs. historical growth
Required growth from the reverse DCF below. Historical CAGRs calculated directly from 10-K FY2021–FY2025.
Sensitivity: what if the discount rate moves?
| WACC | Required growth (TTM FCF) | Required growth (FY2025 annual FCF) |
|---|---|---|
| 8% | 21.0% | 16.8% |
| 9% | 23.7% | 19.4% |
| 10% (base case) | 26.3% | 21.9% |
| 12% | 30.9% | 26.3% |
Either large-cap (8–9%) or high-growth/high-volatility (12%) discount rate assumptions are defensible for Alphabet; across the whole range, the required growth stays well above the company's historical revenue growth rate.
What would move this number
- Which FCF figure you use matters most. Trailing-12-month FCF (as of Q2 2026) was $53.3B — 27% below FY2025's annual FCF of $73.3B — because 2026 capex guidance nearly doubled again. Using the annual figure instead of TTM lowers the required growth rate from 26.3% to 21.9%.
- An 8% discount rate lowers the TTM-basis requirement to 21.0%.
- Extending the projection window or changing the terminal growth assumption would shift the number further, but the core finding — that the market's ask clears Alphabet's historical growth by a wide margin either way — doesn't flip.

- Total debt (long-term + current portion)$48.5B — 10-K FY2025, p.48, p.71
- Net cash+$78.3B (cash minus debt); target EV = market cap − net cash = $4.1317T
- Free cash flow usedTTM (Jun 2026): $53.3B — Q2 FY2026 earnings call; FY2025 annual (comparison): $73.3B — 10-K FY2025
- Discount rate (WACC)10% base case (8–12% tested)
Why show two FCF bases: TTM FCF ($53.3B) sits 25.8% below the trailing 3-year (2023–2025) average of $71.8B — inside the ±40% normalization threshold, but the trend and its cause (capex surge) are clear enough that we present both the TTM and FY2025 annual bases side by side rather than picking one.
Model: free cash flow is assumed to grow at a constant annual rate g for 10 years, then at a 2.5% terminal rate thereafter, solved by bisection for the value of g that equates present value to today's enterprise value.
The fine print
- Change the discount rate, the FCF base, the projection window, or the terminal growth rate, and the answer moves.
- A reverse DCF shows what the market currently expects — it does not say what the stock is "worth."
- Whether 22–26% annual FCF growth is realistic depends on Google Cloud's margin trajectory and whether AI infrastructure spending converts to revenue on the assumed timeline — not on this math alone.
- Any investment decision, and its outcome, is your own responsibility.
