Does the June share price for Castrol India Limited (NSE:CASTROLIND) reflect what it's really worth? Today, we will estimate the stock's intrinsic value by taking the expected future cash flows and discounting them to today's value. The Discounted Cash Flow (DCF) model is the tool we will apply to do this. Don't get put off by the jargon, the math behind it is actually quite straightforward.

Remember though, that there are many ways to estimate a company's value, and a DCF is just one method. Anyone interested in learning a bit more about intrinsic value should have a read of the Simply Wall St analysis model.

Is Castrol India fairly valued?

We're using the 2-stage growth model, which simply means we take in account two stages of company's growth. In the initial period the company may have a higher growth rate and the second stage is usually assumed to have a stable growth rate. In the first stage we need to estimate the cash flows to the business over the next ten years. Seeing as no analyst estimates of free cash flow are available to us, we have extrapolate the previous free cash flow (FCF) from the company's last 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:

Levered FCF (₹, Millions) ₹9.36b ₹10.3b ₹11.3b ₹12.2b ₹13.2b ₹14.2b ₹15.3b ₹16.4b ₹17.6b ₹18.8b
Growth Rate Estimate Source Est @ 11.79% Est @ 10.3% Est @ 9.26% Est @ 8.54% Est @ 8.03% Est @ 7.67% Est @ 7.42% Est @ 7.25% Est @ 7.13% Est @ 7.04%
Present Value (₹, Millions) Discounted @ 14% ₹8.2k ₹8.0k ₹7.7k ₹7.4k ₹7.0k ₹6.7k ₹6.3k ₹6.0k ₹5.6k ₹5.3k

("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = ₹68b

After calculating the present value of future cash flows in the initial 10-year period, we need to calculate the Terminal Value, which accounts for all future cash flows beyond the first stage. The Gordon Growth formula is used to calculate Terminal Value at a future annual growth rate equal to the 5-year average of the 10-year government bond yield of 6.8%. We discount the terminal cash flows to today's value at a cost of equity of 14%.

Terminal Value (TV)= FCF2030 × (1 + g) ÷ (r – g) = ₹19b× (1 + 6.8%) ÷ (14%– 6.8%) = ₹301b

Present Value of Terminal Value (PVTV)= TV / (1 + r)10= ₹301b÷ ( 1 + 14%)10= ₹85b

The total value, or equity value, is then the sum of the present value of the future cash flows, which in this case is ₹153b. To get the intrinsic value per share, we divide this by the total number of shares outstanding. Relative to the current share price of ₹134, the company appears about fair value at a 13% discount to where the stock price trades currently. Remember though, that this is just an approximate valuation, and like any complex formula - garbage in, garbage out.

Important assumptions

Now the most important inputs to a discounted cash flow are the discount rate, and of course, the actual cash flows. Part of investing is coming up with your own evaluation of a company's future performance, so try the calculation yourself and check your own assumptions. 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 Castrol India 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 14%, which is based on a levered beta of 0.974. 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.

Moving On:

Whilst important, the DCF calculation shouldn't be the only metric you look at when researching a company. DCF models are not the be-all and end-all of investment valuation. Instead the best use for a DCF model is to test certain assumptions and theories to see if they would lead to the company being undervalued or overvalued. For instance, if the terminal value growth rate is adjusted slightly, it can dramatically alter the overall result. For Castrol India, there are three additional factors you should consider:
