    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.

    To get Present Value= Future Value÷(1+rate)^no. of years.
    e.g. PV= 121÷ (1.1)^2=$100
    $21 is the interest
    Note: solve first the exponent then divide from FV.
    To get Future Value= Present Value x (1+rate)^no. of years
    e.g. FV= 100 x (1.1)^2 = $121
    $21 is the interest
    note: solve first the exponent then multiply from PV to get FV.

  • @ed0985587
    @ed0985587 10 років тому +11

    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...

    You can apply this for a business?
    I own a company and charge $35 a month for customers to come and play video games at my suite but am thinking of offering a discount to customers if pay a 6 month subscription. If they pay $150 for a subscription, that's about a $10 discount each month ($60 total). Would it be wise of me in doing this? I currently have about 150 people signed up for my subscription service paying $35 a month. I am trying to understand if this is in the best interest to offer something like this...

    • @MiamiAKAtude08
      @MiamiAKAtude08 7 років тому

      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.

    I think time is invaluable, meaning nothing can value as much as time in its infinite scope (just a cultural opinion of mine) in any given week you could make a ridiculous life changing sale, or find inspiration to the next big brilliant business idea that pulls through. Anything could build up to, through time. But I guess a big point of money is to, overtime, as a society, value things as we see them (supply and demand). I bet this too is why then interest rates are so studied by the Fed, because whatever interests over time in an economy, defines spontaneously what our society values the future as (and money flow over time) - monetarily. Without that in mind, I bet that’s what happened to banks and individuals in the 1920s, too much trust in our system without thinking of how an economy can flow over time, thinking the now rather with eternalperspective, so there was a huge spill that broke our system (our trust)
    These are just thoughts I had running in my head while watching the video

      @heather3037 4 роки тому

      Ignacio sarrado that’s part of the example and no maths was done to get to there, it’s just showing you that interest rates can get you $110, so it’s better to choose them over an offer from someone of $109 over that period.

    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.

    What if we find the present value of $65 through this way: First find 10% of $65 and then subtract that amount from $65.
    10% of $65 : 10 x 65 /100 = 6.5
    65 - 6.5 = 58.5
    What is wrong with my way of solution?
