What is the term to describe how : having money makes money?

its basically called compounding i believe, having money that will roll over to make you more money, which will do the same and in turn keep going until you die.

it is called legal theft note that 'money makes money' HAS to mean that the person doesnt make the money [or else there is no meaning to 'money makes money'] - & if the person doesnt make the money, other ppl have to make the money [because all money is made by work - no work, money's value is zero - money is backed only by products of work, fruits of labour - twice as much product-making, with same amount of money, means money buys twice as much product - all the money = all the work - nth of the money = nth of the work] when money makes money [better to say: money RAKES money, ie the extractive economy, not the productive econ] the person gets money without working, & yet the money buys goods made by work - so money makes money HAS TO mean money steals money, ie the moneyowner gets goods without working [overpay], which means others have to get working without money [underpay, wageslavery, slavery] [in previous ages, possibly more awake & aware of evil consequences, money making money was regarded as an obscenity, a perversion, an obvious injustice, an unhappiness-maker, a destroyer of order, an enemy] there are only three ways to get money: by work, by theft & by beggary - if the workers/makers of money get so little, it is because the thieves & beggars [the rakers, the legal thieves] get so much it is extraordinary inexplicable that the ppl cannot see that SOMETHING is very very very wrong, when income [increase of fortune] is so wideranging [$1, to $1 BILLION /fortnight's work] & work is so narrowranging [the average person works over 50 hrs/wk [2 bn homemakers work 70-90hrs/wk], so the hardest worker CANNOT work more than TWICE as hard as the average [& probably works much less than twice as hard] ] [&, if we pay tertiary students for studying, there are NO REASONS for higher than average pay/hr - arguments for higher pay/hr for risk, responsibility, skill, experience, talent, brains, muscle, beauty, gifts, hard work, perseverance, dedication, extraordinary abilities, love of job, etc are all full of very big holes] there HAS to be an enormous amount of LEGAL THEFT - including 'money makes money' but ppl seem to be unable & even UNWILLING to realise it - although realising it wd give 99% of ppl another $70,000/yr of their earnings back, make 100% of ppl 100 times happier, & destroy almost all violence [war & crime], tyranny & undemocracy see my other answers for proofs

IT TAKES MONEY TO MAKE MONEY. IT'S A OLD SAYING. BUT A TRUE SAYING.

investment. profit. or so.

You have to have money to invest into something else that makes money. Yes, it also applies to compounding interest too. If you don't have the money for a stock, you can't buy one. If you don't have the money for art, you can't buy art that increases in value fast. If you don't have money to buy a business, you can't make money off the business... and so on.
