How can I calculate interest portion of income when selling a stock?
When you sell the stock your income is from the difference of prices between when you bought the stock and when you sold it. There's no interest there. The interest is in two places: the underlying company assets (which you own, whether you want it or not), and in the distribution of the income to the owners (the dividends). You can calculate which portion of the interest income constitutes your dividend by allocating the portions of your dividend in the proportions of the company income. That would (very roughly and unreliably, of course) give you an estimate what portion of your dividend income derives from the interest. Underlying assets include all the profits of the company that haven't been distributed through dividends, but rather reinvested back into the business. These may or may not be reflected in the market price of the company. Bottom line is that there's no direct correlation between the income from the sale of the stake of ownership and the company income from interest, if any correlation at all exists. Why would you care about interest income of Salesforce? Its not a bank or a lender, they may have some interest income, but that's definitely not the main income source of the company. If you want to know how much interest income exactly the company had, you'll have to dig deep inside the quarterly and annual reports, and even then I'm not sure if you'll find it as a separate item for a company that's not in the lending business. "Their interest expense was $17M. Where you see $5.14/sh in Key Statistics, any daily interest received is more than canceled out by the expense paid at the same time. I understand your concern, but this company is not ""sitting on cash"" as are Apple, Google, etc. Short term rates are well below 1%, 1yr tbill looks like about .2%. So strictly speaking, each share might have 1 cent interest you need to concern yourself with. Disclaimer to other readers - This has nothing to do with taxes. OP is asking about a specific part of the company cash flow. His worst case is $1 per 100 shares."
A traditional bank is not likely to give you a loan if you have no source of income. Credit card application forms also ask for your current income level and may reject you based on not having a job. You might want to make a list of income and expenses and look closely at which expenses can be reduced or eliminated. Use 6 months of your actual bills to calculate this list. Also make a list of your assets and liabilities. A sheet that lists income/expenses and assets/liabilities is called a Financial Statement. This is the most basic tool you'll need to get your expenses under control. There are many other options for raising capital to pay for your monthly expenses: Sell off your possessions that you no longer need or can't afford Ask for short term loan help from family and friends  Advertise for short term loan help on websites such as Kijiji Start a part-time business doing something that you like and people need. Tutoring, dog-walking, photography, you make the list and pick from it. Look into unemployment insurance. Apply as soon as you are out of work. The folks at the unemployment office are willing to answer all your questions and help you get what you need. Dip into your retirement fund. To reduce your expenses, here are a few things you may not have considered: If you own your home, make an appointment with your bank to discuss renegotiation of your mortgage payments. The bank will be more interested in helping you before you start missing payments than after. Depending on how much equity you have in your home, you may be able to significantly reduce payments by extending the life of the mortgage. Your banker will be impressed if you can bring them a balance sheet that shows your assets, liabilities, income and expenses.   As above, for car payments as well. Call your phone, cable, credit card, and internet service providers and tell them you want to cancel your service. This will immediately connect you to Customer Retention. Let them know that you are having a hard time paying your bill and will either have to negotiate a lower payment or cancel the service. This tactic can significantly reduce your payments. When you have your new job, there are some things you can do to make sure this doesn't happen again: Set aside 10% of your income in a savings account. Have it automatically deducted from your income at source if you can. 75% of Americans are 4 weeks away from bankruptcy. You can avoid this by forcing yourself to save enough to manage your household finances for 3 - 6 months, a year is better. If you own your own home, take out a line of credit against it based on the available equity. Your bank can help you with that. It won't cost you anything as long as you don't use it. This is emergency money; do not use it for vacations or car repairs. There will always be little emergencies in life, this line of credit is not for that.  Pay off your credit cards and loans, most expensive rate first. Use 10% of your income to do this. When the first one is paid off, use the 10% plus the interest you are now saving to pay off the next most expensive card/loan. Create a budget you can stick to. You can find a great budget calculator here: http://www.gailvazoxlade.com/resources/interactive_budget_worksheet.html Note I have no affiliation with the above-mentioned site, and have a great respect for this woman's ability to teach people about how to handle money. "You have multiple issues buried within this question. First, we don't know your tax bracket. For my answer, I'll assume 25%. This simply means that in 2016, you'll have a taxable $37,650 or higher.  The interesting thing is that losses and gains are treated differently. A 25%er's long term gain is taxed at 15%, yet losses, up to $3000, can offset ordinary income. This sets the stage for strategic tax loss harvesting. In the linked article, I offered a look at how the strategy would have resulted in the awful 2000-2009 decade producing a slight gain (1%, not great, of course) vs the near 10% loss the S&P suffered over that time. This was by taking losses in down years, and capturing long term gains when positive (and not using a carried loss).  Back to you - a 15%er's long term gain tax is zero. So using a gain to offset a loss makes little sense. Just as creating a loss to offset the gain. The bottom line? Enjoy the loss, up to $3000 against your income, and only take gains when there's no loss. This advice is all superseded by my rule ""Don't let the tax tail wag the investing dog."" For individual stocks, I would never suggest a transaction for tax purposes. You keep good stocks, you sell bad ones. Sell a stock to take a short term loss only to have it recover in the 30 day waiting period just once, and you'll learn that lesson. Learn it here for free, don't make that mistake at your own expense." The key to understanding a mortgage is to look at an amortization schedule.  Put in 100k, 4.5% interest, 30 years, 360 monthly payments and look at the results.  You should get roughly 507 monthly P&I payment.  Amortization is only the loan portion, escrow for taxes and insurance and additional payments for PMI are extra. You'll get a list of all the payments to match the numbers you enter.  These won't exactly match what you really get in a mortgage, but they're close enough to demonstrate the way amortization works, and to plan a budget.  For those terms, with equal monthly payments, you'll start paying 74% interest from the first payment.  Each payment thereafter, that percentage drops. The way this is all calculated is through the time value of money equations.  https://en.wikipedia.org/wiki/Time_value_of_money.  Read slowly, understand how the equations work, then look at the formula for Repeating Payment and Present Value.  That is used to find the monthly payment.   You can validate that the formula works by using their answer and making a spreadsheet that has these columns:  Previous balance, payment, interest, new balance.  Each line represents a month.  Calculate interest as previous balance * APR/12.  Calculate new balance as previous balance minus payment plus interest. Work through all this for a 1 year loan and you will understand a lot better. If any academic framework worked, your teachers would be the richest people on the planet. However, you must read up on macro and micro economic factors and make an educated guess where the market(or stock) would be at the date of expiry. Subtract the Strike Price from your determined price and calculate your potential profit. Then, if you are getting paid more or less the same thing as of today, sell it and switch to a safer investment till expiry (For example:- Your potential profit was $10, but you are getting $9 as of today, you can sell it and earn interest(Safer investment) for the remaining time.) Its just like buying and selling stocks. You must set a target and must have a stop loss. Sell when you reach that target, and exit if you hit the stop loss. If you have none of these, you will always be confused(Personal experience). Depends on if the stock pays a dividend or not. Some companies in their early years may choose to not pay dividends. Your calculations are off as the dividend stated is annual that you'd have to divide by 4 to get what the quarterly amount would be and there can be variances as Ellison's compensation package may well include options so that the number of shares he owns could fluctuate over the course of a year. "If you mean, If I invest, say, $1000 in a stock that is growing at 5% per year, versus investing $1000 in an account that pays compound interest of 5% per year, how does the amount I have after 5 years compare? Then the answer is, They would be exactly the same.  As Kent Anderson says, ""compound interest"" simply means that as you accumulate interest, that for the next interest cycle, the amount that they pay interest on is based on the previous cycle balance PLUS the interest. For example, suppose you invest $1000 at 5% interest compounded annually. After one year you get 5% of $1000, or $50. You now have $1050. At the end of the second year, you get 5% of $1050 -- not 5% of the original $1000 -- or $52.50, so you now have $1102.50. Etc. Stocks tend to grow in the same way. But here's the big difference: If you get an interest-bearing account, the bank or investment company guarantees the interest rate. Unless they go bankrupt, you WILL get that percentage interest. But there is absolutely no guarantee when you buy stock. It may go up 5% this year, up 4% next year, and down 3% the year after. The company makes no promises about how much growth the stock will show. It may show a loss. It all depends on how well the company does." The point of a total return index is that it already has accounted for the capital gains + coupon income. If you want to calculate it yourself you'll have to find the on-the-run 10y bond for each distinct period then string them together to calc your total return. Check XLTP if they have anything In the United States Short-term capital gains are taxed at rates similar to regular income which is 25% if you make less than $91,000 and 28% if you make more than that but less than $190,000. If you make more than $190,000 then the rate is 33%. If you hold the stock for a year or more than the tax rate is 15%, unless your income is less than $33,000 in which case there is no tax on long-term gains. As a general rule, the way to make money is to stay out of debt, so I cannot advise you to assume a mortgage. Financially you are better off investing your money. Much like you I bought a house with a mortgage using about $30,000 in a down payment about 20 years ago and I paid it off a few years ago. If I had to do it over again, I would have bought a shack (a steel building) for $30,000 and lived in that and invested my income. If I had done that, I would be about $500,000 richer today than I am now.
