850. About dividend percentage
Dividend prices are per share, so the amount that you get for a dividend is determined by the number of shares that you own and the amount of the dividend per share. That's all. People like to look at dividend yield because it lets them compare different investments; that's done by dividing the dividend by the value of the stock, however determined. That's the percentage that the question mentions. A dividend of $1 per share when the share price is $10 gives a 10% dividend yield. A dividend of $2 per share when the share price is $40 gives a 5% dividend yield. If you're choosing an investment, the dividend yield gives you more information than the amount of the dividend.

851. Do I need a business credit card?
It can certainly help build a credit score, but remember that businesses gain credit differently from individuals.  Depending on the country, there isn't usually a national register of business credit ratings the way there is for individuals.  The credit record you'd be gaining is with your own bank only. Banks will usually base your business credit record on revenue and transactional loads rather than merely on having and holding a credit card.  That said, it isn't always that easy to get a business credit card and so it is a useful thing to have for credibility with clients (depending on the type of work you do). A credit card can also sometimes work out cheaper (and faster) for financing small overdrafts than a regular business overdraft facility.  That said, I've found that larger loans over a five-year term can work out much cheaper for an established business than they would for an individual, even where the business itself has no history of using credit.

852. How does GST on PayPal payments work for Australian Taxation?
Regardless of wether or not you are registered for GST, you are legally required to include a GST total on every invoice sent to an Australian customer. This GST total must be 10% of the payment amount if you are registered for GST, or it must be $0.00 if you are not registered for GST. Since all GST transactions with the government are in Australian dollars, this amount on the invoice also needs to be in AUD, or else it's impossible for you and your customer to both be working off the same GST amount. This means you need to transfer your money from USD to AUD in PayPal's "Manage Currencies" area before you can send a tax invoice to the customer, so that you can provide the correct amount in AUD based on the actual exchange rate for the day (and you are required to send invoices promptly). Alternatively, you can collect payments in AUD using PayPal or use a different payment service that collects payments in USD but immediately converts them to AUD for sending an invoice (australian paypal competitors often provide this service).

853. How does the Dow Jones Industrial Average (DJIA) divisor change to account for dividends?
Scrip dividends are similar to stock splits. With a stock split, 100 shares can turn into 200 shares; with scrip dividends they might turn into 105 shares.

854. What is inflation?
Inflation refers to the money supply. Think of all money being air in a balloon. Inflation is what happens when you blow more air in the balloon. Deflation is what happens when you let air escape. Inflation may cause prices to go up. However there are many scenarios possible in which this does not happen. For example, at the same time of inflation, there might be unemployment, making consumers unable to pay higher prices. Or some important resource (oil) may go down in price (due to political reasons, war has ended etc), compensating for the money having less value.  Similarly, peoples wages will tend to rise over time. They have to, otherwise everyone would be earning less, due to inflation. However again there are many scenarios in which wages do not keep up with inflation, or rise much faster. In fact over the past 40 years or so, US wages have not been able to keep up with inflation, making the average worker 'poorer' than 40 years ago. At its core, inflation refers to the value of the money itself. As all values of other products, services, assets etc are expressed in terms of money which itself also changes value, this can quickly become very complex. Most countries calculate inflation by averaging the price change of a basket of goods that are supposed to represent the average Joe's spending pattern. However these methods are often criticized as they would be 'hiding' inflation. The hidden inflation may come back later to bite us.

855. Must ETF companies match an investor's amount invested in an ETF?
The point here is actually about banks, or is in reference to banks. They expect you know how a savings account at a bank works, but not mutual funds, and so are trying to dispel an erroneous notion that you might have -- that the CBIC will insure your investment in the fund.  Banks work by taking in deposits and lending that money out via mortgages. The mortgages can last up to 30 years, but the deposits are "on demand". Which means you can pull your money out at any time.  See the problem? They're maintaining a fiction that that money is there, safe and sound in the bank vault, ready to be returned whenever you want it, when in fact it's been loaned out. And can't be called back quickly, either. They know only a little bit of that money will be "demanded" by depositors at any given time, so they keep a percentage called a "reserve" to satisfy that, er, demand.  The rest, again, is loaned out. Gone.  And usually that works out just fine. Except sometimes it doesn't, when people get scared they might not get their money back, and they all go to the bank at the same time to demand their on-demand deposits back. This is called a "run on the bank", and when that happens, the bank "fails". 'Cause it ain't got the money.  What's failing, in fact, is the fiction that your money is there whenever you want it. And that's really bad, because when that happens to you at your bank, your friends the customers of other banks start worrying about their money, and run on their banks, which fail, which cause more people to worry and try to get their cash out, lather, rinse repeat, until the whole economy crashes. See -- The Great Depression.  So, various governments introduced "Deposit Insurance", where the government will step in with the cash, so when you panic and pull all your money out of the bank, you can go home happy, cash in hand, and don't freak all your friends out. Therefore, the fear that your money might not really be there is assuaged, and it doesn't spread like a mental contagion. Everyone can comfortably go back to believing the fiction, and the economy goes back to merrily chugging along.  Meanwhile, with mutual funds & ETFs, everyone understands the money you put in them is invested and not sitting in a gigantic vault, and so there's no need for government insurance to maintain the fiction.  And that's the point they're trying to make.  Poorly, I might add, where their wording is concerned.

856. Is it irresponsible for me to lease a $300/month car for 18 months?
With a gross income of $ 95,000 per year, and a net savings rate of over $ 18,000 per year, a budget of $ 3,600 per year for automobile interest and depreciation is not irresponsible. But poor car choices, poor car maintenance habits, and driving habits that risk totalling cars are irresponsible.  Also, not fully understanding a lease deal is irresponsible. The "great lease deal" might be encouraging you to make a different "poor car choice" than you made last time.  A "great deal" on a bad car is not really a great deal.  Also, depending on the contract and your driving habits, you might have a surprising cost at the end of the lease.

857. What are the advantages and disadvantages of leasing out a property or part of a property (such as a basement apartment)?
Complexity has mentioned some good points. I'd also like to add on the downsides:  It's not that easy to get rid of a tenant!  Imagine if your tenant passed your background check with flying colors but then turned out to be the tenant from hell...  How would you resolve the situation?  If the thought of that kind of situation stresses you (it would stress me!), I would consider carefully whether you really want to be a landlord.

858. It is worth using a discount stock broker? I heard they might not get the best price on a trade?
Always use limit orders never market orders. Period. Do that and you will always pay what you said you would when the transaction goes through. Whichever broker you use is not going to "negotiate" for the best price on your trade if you choose a market order.  Their job is to fill that order so they will always buy it for more than market and sell it for less to ensure the order goes through. It is not even a factor when choosing between TradeKing and Scottrade. I use Trade King and my friend uses ScottTrade.  Besides the transaction fee (TK is a few $$ cheaper), the only other things to consider are the tools and research (and customer service if you need it) that each site offers. I went with TK and the lower transaction fee since tools and research can be had from other sources. I basically only use it when I want to make a trade since I don't find the tools particularly useful and I never take an analyst's opinion of a stock at face value anyway since everybody always has their own agenda.

859. Why can't 401(k) statements be delivered electronically?
There are a lot of unintended consequences of fairly arbitrary IRS guidelines when it comes to 401Ks, they both close and create tons of loopholes and many companies are left to implement their own policy around these laws. Ultimately what you are left with are a lot of random things, interpreted differently by every single company in the country, that aren't directly codified by the IRS or Congress. If you have a choice regarding what brokerage firm manages your 401(k), then just call around. Be sure to ask the pencil pusher on the phone to double check because they might say "OF COURSE you can get paperless statements it is 2015" but then when you sign up it becomes "ooohhh sorry due to recent guidelines this kind of account isn't eligible for paperless statements"

860. Close to retirement & we may move within 7 years. Should we re-finance our mortgage, or not?
Think of your mortgage this way - you have a $130K 16 year mortgage, at 6.75%.  At 4%, the same payment ($1109 or so) will pay off the loan in 12.4 years. So, I agree with littleadv, go for a 15yr fixed (but still make the higher payment) or 10 yr if you don't mind the required higher payment. Either way, a refinance is the way to go.  Edit - My local bank is offering me a 3.5% 15 yr loan with fees totaling $2500. For the OP here, a savings of 3.25% or first year interest savings of $4225. 7 months to breakeven.  It's important not to get caught up in trying to calculate savings 15-20 years out. What counts today is the rate difference and looking at it over the next 12 months is a start. If you break even to closing costs so soon, that's enough to make the decision.

861. How to determine contractor hourly rate and employee salary equivalents?
Take $100,000 base salary, x 1.5 = $150,000 contractor salary, divide by 1,872 hours = $80/hr

862. Why should I trust investment banks' ratings?
If there's indeed no reason to trust GS, i.e. those are just guides   then the question is: Why do investors seem to care? Because there's a reason to trust. You're just reading the bottom line - the target price range. More involved investors read the whole report, including the description of the current situation, the premises for the analysis, the expectations on the firm's performance and what these expectations are based on, the analysis of how the various scenarios might affect the valuation, and the evaluation of chances of these scenarios to occur. You don't have to trust everything and expect it to be 100% correct, analysts are not prophets. But you do have an option of reading their reports and critically analyzing their conclusions. What you suspect GS of doing ("I tend to believe those guys just want themselves a cheap buy price a few days before Q2 earnings release") is a criminal offence.

863. Bonds vs equities: crash theory
Diversify into leveraged short/bear ETFs and then you can quit your job and yell at your boss "F you I'm short your house!" edit: this is a quote from Greg Lippmann and mentioned in the book "The Big Short"

864. What are the real risks in “bio-technology” companies?
Be wary of pump and dump schemes. This scheme works like this: When you observe that "From time to time the action explodes with 100 or 200% gains and volumes exceeding one million and it then back down to $ 0.02", it appears that this scheme was performed repeatedly on this stock. When you see a company with a very, very low stock price which claims to have a very bright future, you should ask yourself why the stock is so low. There are professional stock brokers who have access to the same information you have, and much more. So why don't they buy that stock? Likely because they realize that the claims about the company are greatly exaggerated or even completely made up.

865. Why is there so much variability on interest rate accounts
Pay attention to nickel-and-dime charges (atm fees, low balance fees, limit on atm transactions per month, charge for human teller transaction, charge for paper statements or tax records).  Consider that a financial company will spend on the order of $100-500 to sign up a good customer.  Are you getting this in a cash bonus, competitive high interest rate, reasonable other gift, or advertising directed at your eyeballs?  A variation in rates less than 1% easily fits into a marketing cost and there doesn't have to be any other magic to it.

866. Employer no longer withholds, how do I self administer 401k
You can't be doing it yourself. Only your employer can do it. If the employer doesn't provide the option - switch employers. The only way for you to do it yourself is if you're the employer, i.e.: self-employed.
