Why when you get your money matters as much as how much money. Present and future value also discussed. Created by Sal Khan.

All this is done on the assumption that all other factors are held constant.

What is Time Value of Money and more importantly, how does it affect your personal finance? The time value of money (TVM) is an important concept to investors because a dollar on hand today is worth more than a dollar promised in the future; the dollar on hand today can be used to invest and earn interest or capital gains.

kaif muhammad (1 year ago)
thank you so much but I have little bit problem in last of the lecture where you did the present value of $65 in one year, how is it calculating if we'll find for more than one year ?
Capricorn GoddessNika (1 year ago)
kaif muhammad You must already know the amount in the future you are solving for (the amount and the interest you expect to make. You must also know the interest rate. You divide that total by (1 + interest rate as a decimal) to reach how much you must lay out now to reach that future amount... It's not an "each year" calculation. It's one calculation done on, say , year 5, for example (where you already know the total cash layout and interest you expect to get in year 5) and you divide that total by (1+iterest rate as a decimal) to reach present value.

Very concise and to the point. Provided exceptional clarity on a subject the text attempted to explain through nearly 70 rambling pages.

Take into consideration that money is taxed (interest rate paid by the bank). Factoring taxation and inflation, the money you make off interest (in small sums) is essentially irrelevant. So actually make money in this fashion, you'd have to save large sums. IMO, you're better off investing your money elsewhere...

That's not just your opinion, that's the opinion of anyone that knows how money works

@kristopheraugust Indeed, I don't know that much about Austrian Economics. However capitalism is the only economic system which supports a free people. That's why I defend it.
mrhnm (7 years ago)
@kristopheraugust Ron Paul used the Austrian Business cycle to predict the housing crash 5 years before it happened. Moral is there is one real world example that proves that that guy is full of shit.
Pat Gunn (7 years ago)
@kristopheraugust You may predict that people won't waste time debating you, but that doesn't make your interpretation of that event correct.
Pat Gunn (7 years ago)
@kristopheraugust It's already failed to be accepted by the scholars on the topic. If you want to beat your head against the right brick wall, go find one of them who's willing to waste some time (akin to biologists who would waste their time debating one of the hordes of creationists rather than actually doing research). Academia has well-established ways of tossing out the kooks. If you want back in, don't expect fancy wordplay in debate to help. Scientists don't usually debate, they publish
mrhnm (7 years ago)
@pgunn01 Yep because the majority is always right.
Pat Gunn (7 years ago)
@mrhnm That's an extreme minority opinion. Austrian economics is based on a view of human nature that's incorrect (praxeology), and it has no predictive power and little impact in academia apart from what's been attained through donations of clueless libertarians. Sal would be wasting his time to teach it.
mrhnm (7 years ago)
Inflation is a symptom of the fiat monetary system.
mrhnm (7 years ago)
@pgunn01 Because it's the only system that isn't bullshit.
Pat Gunn (7 years ago)
@mrhnm Why? It's a discredited/fringe theory. You might as well have Sal waste his time teaching us Klingon.
mrhnm (7 years ago)
Let's see some vids on the Austrian System of economics! Pretty Please!

@nicochunger The little hand "mouse" is easier to see when he is pointing to something. The other cursor is difficult to see. Either i have to improve my eyesight or you have to get over your irrational fear of pixels:)

@cuppajoesugar Also, a wealthy man makes more money than his wife can spend.

Time preference plays an important role in setting interest rates. If there was no interest, there would not be any (financial) incentive to forgo current consumption for later satisfaction. Immediate satisfaction is more preferable than delayed but Fiat money can distort the true state of economic conditions.
Oscar Yang (7 years ago)
just do it like this: 65 x 100 / 110 = 59,09 :D
Woman = Time x Money Time = Money Woman = (Money)2 Money = (Problems)(1/2) Woman = Problems
