Last year I Suppose you put $ 100 in some savings account. This is from last year Exactly one year later From $ 100 to $ 110 This is what I mean now So if you look at this money in dollars only It has increased by $ 10 So I made $ 10 on my initial $ 100 capital So I get 10% profit But I think Did this investment really pay off? What can I buy for this $ 110? Compared to what you could buy for $ 100 before. Compared to what I was able to buy with this money last year, I really like my products and services Can I buy 10% more today? Think about it Let's think about it. Last year and this year Rough inflation rate Inflation is 2% a year later Let's say it went up. If only this would happen What happened to $ 100 last year and today? Well done! If the inflation rate is 2% And a year later, the equivalent of $ 100 You can buy it today for $ 102 So that's going to be $ 102 So how much would you be prepared to pay for all those benefits to your life?

And we's the first investment in money today $ 102 …. Once that is done, we have developed a calculator Dividing 8 by 102 gives you 7.8 percent This is equivalent to 7.8% This is a nominal profit, though At the exchange rate for what we invested Looking back at what we got Even if the nominal return is 10% Because there was 2% inflation Our actual purchasing power increased by only 7.8%..
