The same amount of money is worth less in the future than it is in the present because it can grow even at a risk free rate.
Yes, I need some of my money now to pay my expenses. But if you had 200K extra to invest in 2010 and chose to invest it and instead chose to work somewhere paying $200K less than you could have thinking I can make $200K more in 14 years. You would have lost out on 605% returns.
What do you think you are doing when you “invest” in the stock market?
Yes I know when you buy stocks aside from the IPO or secondary offering you’re buying from other people and the company doesn’t get the money directly.
The value of the money to you or the business is worth more now than 10 years from now. Meaning just like I said, it makes more sense for you as an individual to have made $300K and live off $100K and invest it in 2010 than to wallow in obscurity at failing startups and then start saving at 35.
This is the textbook definition of the time value of money - as quoted from Investopedia.
I have one other way to describe this line of reasoning:
- money is more valuable now because you can start earning interest
- but why are others willing to pay interest?
- because the money is more valuable to them now
This is circular. Why would money magically get more valuable in the future?
Money is valuable for its uses, not intrinsically.
The reason why you can get interest on money is because people and businesses need it NOW to do productive things, more badly than in the future.
This is the entire principle behind discounting cash flows.
