Can I make my savings keep in check with or beat inflation over a long time period via index funds?
If I invest in index funds or other long term stocks that pay dividend which I reinvest, they don't need to be worth more per share for me to make a profit, right? That is, if I sell part of the stocks, it's GOOD if they're worth more than I bought them at, but the real money comes from the QUANTITY of stocks that you get by reinvesting your dividends, right? I would say it is more the other way around.  It is nice to get dividends and reinvest them, but overall the main gain comes from the stocks going up in value. The idea with index funds, however, is that you don't rely on any particular stock going up in value; instead you just rely on the aggregate of all the funds in the index going up.  By buying lots of stocks bundled in an index fund, you avoid being too reliant on any one company's performance. Can I invest "small amounts" (part of paycheck) into index funds on a monthly basis, like €500, without taking major "transaction fees"? (Likely to be index fund specific... general answers or specific answers using popular stocks welcomed). Yes, you can.  At least in the US, whether you can do this automatically from your paycheck depends on whether you employer has that set up.  I don't know that work in the Netherlands.  However, at the least, you can almost certainly set up an auto-invest program that takes $X out of your bank account every month and buys shares of some index fund(s). Is this plan market-crash proof? My parents keep saying that "Look at 2008 and think about what such a thing would do to your plan", and I just see that it will be a setback, but ultimately irrelevant, unless it happens when I need the money. And even then I'm wondering whether I'll really need ALL of my money in one go. Doesn't the index fund go back up eventually? Does a crash even matter if you plan on holding stocks for 10 or more years? Crashes always matter, because as you say, there's always the possibility that the crash will occur at a time you need the money.  In general, it is historically true that the market recovers after crashes, so yes, if you have the financial and psychological fortitude to not pull your money out during the crash, and to ride it out, your net worth will probably go back up after a rough interlude.  No one can predict the future, so it's possible for some unprecedented crisis to cause an unprecedented crash.  However, the interconnectedness of stock markets and financial systems around the world is now so great that, were such a no-return crash to occur, it would probably be accompanied by the total collapse of the whole economic system.  In other words, if the stock market dies suddenly once and for all, the entire way of life of "developed countries" will probably die with it.  As long as you live in such a society, you can't really avoid "gambling" that it will continue to exist, so gambling on there not being a cataclysmic market crash isn't much more of a gamble. Does what I'm planning have similarities with some financial concept or product (to allow me to research better by looking at the risks of that concept/product)? Maybe like a mortgage investment plan without the bank eating your money in between? I'm not sure what you mean by "what you're planning".  The main financial products relevant to what you're describing are index funds (which you already mentioned) and index ETFs (which are basically similar with regard to the questions you're asking here).  As far as concepts, the philosophy of buying low-fee index funds, holding them for a long time, and not selling during crashes, is essentially that espoused by Jack Bogle (not quite the inventor of the index fund, but more or less its spiritual father) and the community of "Bogleheads" that has formed around his ideas.  There is a Bogleheads wiki with lots of information about the details of this approach to investing.  If this strategy appeals to you, you may find it useful to read through some of the pages on that site.
