In this article we are going to estimate the intrinsic value of Alphabet Inc. (NASDAQ:GOOG.L) by taking the expected future cash flows and discounting them to their present value. I will be using the Discounted Cash Flow (DCF) model. Don't get put off by the jargon, the math behind it is actually quite straightforward.

Companies can be valued in a lot of ways, so we would point out that a DCF is not perfect for every situation. Anyone interested in learning a bit more about intrinsic value should have a read of the Simply Wall St analysis model.

### What's the estimated valuation?

We use what is known as a 2-stage model, which simply means we have two different periods of growth rates for the company's cash flows. Generally the first stage is higher growth, and the second stage is a lower growth phase. To start off with, we need to estimate the next ten years of cash flows. Where possible we use analyst estimates, but when these aren't available we extrapolate the previous free cash flow (FCF) from the last estimate or reported value. We assume companies with shrinking free cash flow will slow their rate of shrinkage, and that companies with growing free cash flow will see their growth rate slow, over this period. We do this to reflect that growth tends to slow more in the early years than it does in later years.

Generally we assume that a dollar today is more valuable than a dollar in the future, so we need to discount the sum of these future cash flows to arrive at a present value estimate:

#### 10-year free cash flow (FCF) estimate

2020 | 2021 | 2022 | 2023 | 2024 | 2025 | 2026 | 2027 | 2028 | 2029 | |

Levered FCF ($, Millions) | $35.0b | $41.8b | $48.7b | $56.6b | $62.5b | $67.6b | $72.0b | $75.9b | $79.4b | $82.6b |

Growth Rate Estimate Source | Analyst x15 | Analyst x12 | Analyst x6 | Analyst x5 | Est @ 10.48% | Est @ 8.16% | Est @ 6.53% | Est @ 5.39% | Est @ 4.59% | Est @ 4.03% |

Present Value ($, Millions) Discounted @ 8.7% | $32.2k | $35.4k | $37.9k | $40.5k | $41.2k | $41.0k | $40.2k | $38.9k | $37.5k | $35.9k |

*("Est" = FCF growth rate estimated by Simply Wall St)* **Present Value of 10-year Cash Flow (PVCF)**= $380.6b

We now need to calculate the Terminal Value, which accounts for all the future cash flows after this ten year period. The Gordon Growth formula is used to calculate Terminal Value at a future annual growth rate equal to the 10-year government bond rate of 2.7%. We discount the terminal cash flows to today's value at a cost of equity of 8.7%.

**Terminal Value (TV)** = FCF_{2029} Ã— (1 + g) Ã· (r â€“ g) = US$83b Ã— (1 + 2.7%) Ã· (8.7% â€“ 2.7%) = US$1.4t

**Present Value of Terminal Value (PVTV)** = TV / (1 + r)^{10} = $US$1.4t Ã· ( 1 + 8.7%)^{10} = $616.71b

The total value, or equity value, is then the sum of the present value of the future cash flows, which in this case is $997.33b. In the final step we divide the equity value by the number of shares outstanding. **This results in an intrinsic value estimate of $1438.32**. Relative to the current share price of $1212.19, the company appears about fair value at a 16% discount to where the stock price trades currently. Valuations are imprecise instruments though, rather like a telescope - move a few degrees and end up in a different galaxy. Do keep this in mind.

### The assumptions

The calculation above is very dependent on two assumptions. The first is the discount rate and the other is the cash flows. You don't have to agree with these inputs, I recommend redoing the calculations yourself and playing with them. The DCF also does not consider the possible cyclicality of an industry, or a company's future capital requirements, so it does not give a full picture of a company's potential performance. Given that we are looking at Alphabet as potential shareholders, the cost of equity is used as the discount rate, rather than the cost of capital (or weighted average cost of capital, WACC) which accounts for debt. In this calculation we've used 8.7%, which is based on a levered beta of 1.002. Beta is a measure of a stock's volatility, compared to the market as a whole. We get our beta from the industry average beta of globally comparable companies, with an imposed limit between 0.8 and 2.0, which is a reasonable range for a stable business.

### Next Steps:

Valuation is only one side of the coin in terms of building your investment thesis, and it shouldnâ€™t be the only metric you look at when researching a company. The DCF model is not a perfect stock valuation tool. Rather it should be seen as a guide to "what assumptions need to be true for this stock to be under/overvalued?" If a company grows at a different rate, or if its cost of equity or risk free rate changes sharply, the output can look very different. For Alphabet, I've compiled three important factors you should further research:
