How to calculate stock price (value) based on given values for equity and debt?
There is no formula for calculating a stock price based on the financials of a company. A stock price is set by the market and always has a component built into it that is based on something outside of the current valuation of a company using its financials. Essentially, the stock price of a company per share is whatever the best price it can get on the open market. If you are looking at how to evaluate if a stock is a good value at the current price, then look at some of the answers, but I wanted to answer this based on the way you phrased the question. Adding assets (equity) and liabilities (debt) never gives you anything useful. The value of a company is its assets (including equity) minus its liabilities (including debt). However this is a purely theoretical calculation. In the real world things are much more complicated, and this isn't going to give you a good idea of much a company's shares are worth in the real world I'll give you my quick and dirty way to value a company: A quick and dirty valuation could be: equity + 10 times profit. This quick way protects you from investing in companies in debt, or losing money. To go more in-depth you need to assess future profit, etc. I recommend the book from Mary Buffett about Warren Buffett's investing style.
"To your first comment: yup. To your second comment, A = L + E. If E goes down, and L goes up, the net effect is 0. Then, if L goes down, and A goes up, the net effect is 0 and we are balanced once again. There is no ""rebalancing"" equity. You just have to make sure that, at the end of your journal entries, the accounting equation holds.  It's a very unintuitive concept to wrap your head around, but spend some time mapping out the flow of various journal entries. Once it clicks, you'll really understand the logic." "Market cap is synonymous with equity value, which is one way of thinking of a company's ""worth.""  The alternative would be enterprise value, which is calculated as follows:  Enterprise Value = Market Value of Equity + Market Value of Debt - Cash and Equivalents - Non-Operating Assets  Enterprise value is essentially ""how much is the firm worth to ALL providers of capital."" It can be viewed as ""if I wanted to buy the *entire* company, debt and all, what would I have to pay?""" Too calculate these values, information contained in the company's financial statements (income, balance, or cashflow) will be needed along with the price.  Google finance does not maintain this information for BME.  You will need to find another source for this information or analyze another another symbol's financial section (BAC for example). If you want to see a more academic version of this look up Weighted Average Cost of Capital (WACC).   It's a formula that tells you how much it costs for a company to raise $1 of capital whether it be through issuing bonds or stocks.   One thing you learn is that there are times that if you take on loans (even if you don't need it) you can raise shareholder value and therefore the total company netvalue. The thought process is (as it states in the article above) that a company can issue debt for cheaper than issue shares and it will have extra cash which it can use to get a better return than its net effective interest rate.   I tried to give an example but I only ended up rehashing what it says in the article. Anyhow look up WACC and you'll understand the fundamentals. "Will the investment bank evaluate the worth of my company more than or less than 50 crs. Assuming the salvage value of the assets of 50 crs (meaning that's what you could sell them for to someone else), that would be the minimum value of your company (less any outstanding debts). There are many ways to calculate the ""value"" of a company, but the most common one is to look at the future potential for generating cash.   The underwriters will look at what your current cash flow projections are, and what they will be when you invest the proceeds from the public offering back into the company.  That will then be used to determine the total value of the company, and in turn the value of the portion that you are taking public. And what will be the owner’s share in the resulting public company? That's completely up to you.  You're essentially selling a part of the company in order to bring cash in, presumably to invest in assets that will generate more cash in the future.  If you want to keep complete control of the company, then you'll want to sell less than 50% of the company, otherwise you can sell as much or as little as you want." The three places you want to focus on are the income statement, the balance sheet, and cash flow statement. The standard measure for multiple of income is the P/E or price earnings ratio  For the balance sheet, the debt to equity or debt to capital (debt+equity) ratio. For cash generation, price to cash flow, or price to free cash flow. (The lower the better, all other things being equal, for all three ratios.) "The basic equation taught in day one of accounting school is that Assets = Liabilities + Equity. My first point was that I looked at the actual financial statements published as of the end of the 2nd quarter 2017, and the total liabilities on their audited balance sheet were like $13 billion, not $20b. I don't know where the author got their numbers from.  My second point: Debt usually needs to be paid on prearranged terms agreed upon by the debtor and the debtee, including interest, so it is important for a business to keep track of what they owe and to whom, so they can make timely payments. As long as they have the cash on hand to make payments plus whatever interest they owe, and the owners are happy with the total return on their investment, then it doesn't really matter how debt they have on the balance sheet.  Remember the equation A=L+E. There are precisely two ways to finance a business that wants to acquire assets: liabilities and/or equity. The ""appropriate"" level of debt vs equity on a balance sheet varies wildly, and totally depends on the industry, size of the business, cash flow, personal preferences of the CEO, CFO, shareholders et al, etc.    It gets way more detailed and complicated than that obviously, but the point is that looking at debt alone is a meaningless metric. This is corporate finance and accounting 101, so you can probably find tons of great articles and videos if you want to learn more." Are you trying to figure out if a project would increase the market value of equity?     I think your issue is that the Market value of Equity will not be updated with the NPV of 40M (Assuming it is truly +, not sure if it's true with 50M of debt).      EV = Market Value of Equity + Debt - Cash and CE   Ev - Debt + Cash and CE = Market equity value.     So I think you would have to update the market value of Equity up with 40M. This would then lead to EV = Equity Value + future income stream discounted + debt - Cash and Cash Equivalents. you can check google scholar for some research reports on it.  depends how complex you want to get...  it is obviously a function of the size of the portfolio of each type of asset. do you have a full breakdown of securities held? you can get historical average volumes during different economic periods, categorized by interest rates for example, and then calculate the days required to liquidate the position, applying a discount on each subsequent day. Need help with a finance problem I'm currently facing in my business.  My company might be going through an acquisition and I need to understand how the dilution works out for shareholders.  They currently have large shareholder loans (debt), and will be converting to equity pre-transaction.  For this case, if the original company value = $1 MM and the SHL value = $1 MM, I'm assuming that'd dilute equity by 50% for all shareholders if converted to equity at original company value.  Correct?  However, what if the $1 MM in shareholder loans were converted at the market value of the company, say $4 MM?    I might be confusing myself, but just want to confirm.. thanks! Sure let's say we're starting with the equity value of a public company. Fully diluted shares times market price. We add debt and subtract all cash to give us enterprise value. Calculate a multiple on that. Look what we did up there, we subtracted out all cash. The DCF approach assumes we have an operating level of cash when it calculates a value. You're saying that the DCF spits out an enterprise value. It cannot be an enterprise value if the DCF approach assumes we hold cash. We would have to subtract out an operating level of cash from the DCF concluded value to compare it apples to apples to the cashless enterprise values we derived from the market approach multiples.

"To know if a stock is undervalued is not something that can be easily assessed (else, everybody would know which stock is undervalued and everybody will buy it until it reaches its ""true"" value). But there are methods to assess the value of a company, I think that the 3 most known methods are: If the assets of the company were to be sold right now and that all its   debts were to be paid back right now, how much will be left? This   remaining amount would be the fundamental value of your company. That method could work well on real estate company whose value is more or less the buildings that they own minus of much they borrowed to acquire them. It's not really usefull in the case of Facebook, as most of its business is immaterial. I know the value of several companies of the same sector, so if I want   to assess the value of another company of this sector I just have to   compare it to the others. For example, you find out that simiral internet companies are being traded at a price that is 15 times their projected dividends (its called a Price Earning Ratio). Then, if you see that Facebook, all else being equal, is trading at 10 times its projected dividends, you could say that buying it would be at a discount. A company is worth as much as the cash flow that it will give me in   the future If you think that facebook will give some dividends for a certain period of time, then you compute their present value (this means finding how much you should put in a bank account today to have the same amount in the future, this can be done by dividing the amount by some interest rates). So, if you think that holding a share of a Facebook for a long period of time would give you (at present value) 100 and that the share of the Facebook is being traded at 70, then buy it. There is another well known method, a more quantitative one, this is the Capital Asset Pricing Model. I won't go into the details of this one, but its about looking at how a company should be priced relatively to a benchmark of other companies. Also there are a lot's of factor that could affect the price of a company and make it strays away from its fundamental value: crisis, interest rates, regulation, price of oil, bad management, ..... And even by applying the previous methods, the fundemantal value itself will remain speculative and you can never be sure of it. And saying that you are buying at a discount will remain an opinion. After that, to price companies, you are likely to understand financial analysis, corporate finance and a bit of macroeconomy." Well i dont know of any calculator but you can do the following 1) Google S&P 500 chart 2) Find out whats the S&P index points (P1) on the first date 3) Find out whats the S&P index points (P2) on the second date 4) P1 - P2 = result Maybe one of my issues is that I have a 5 year model with a terminal value. The repayment of debt principal is outside this time frame so I don't assume any repayment.   If you're valuing a company share price though you don't model all debt repayments.
