The Hidden Power of Savings
Initial fixed amount, only once
This system refers to destining an initial amount and keeping it for a long time, long term placed in the “system” at a convenient interest rate. This system does not consider savings payments in a monthly basis, but it is the case of the typical person that gets an important amount of money and desires to do something more with it than to just spend it on consuming all of the nice and attractive products that are advertised. For example:
F = I * ( 1 + r 7 100 ) ^ ( n * 12 )
I = Initial amount, expressed in US dollars.
F = Future Value, expressed in US dollars.
r = monthly interest rate, expressed in %.
n = number of years.
As can be seen, the future value is directly proportioned to the initial savings amount.
