Compound Interest
The Effects of
Compound Interest
The magic or
secret in saving is the power of compound interest. When you're saving,
the financial institution, retirement plan, etc., adds interest to your
savings at regular intervals, generally every month. If you don't touch
the interest, but let it add to your lump sum, then you start to earn
interest on your interest, as well as on the original amount you saved.
This is called compound interest.
The longer you leave your money, the more powerful the compound interest
effect. So the earlier you start saving, the more you make from compound
interest. The same applies to other investments such as the mutual fund
unit shares (available in most retirement plans), where the dividends
and growth of the unit share value is automatically reinvested in your
retirement account.
The Rule of 72
What does it take to save a large some of money? There's an easy
rule you can use to work out how your savings or investments can grow
with compound interest.
Just divide the average annual return into 72. The result tells you how
long it will take for your money to double without further savings.
For example, you have $10,000, which is earning 8% interest (401k
pre-tax). 72 divided by 8 = 9.
Every 9 years your $10,000 will double, therefore:
| After 9 years you have: |
$20,000 |
| After 18 years you have:
|
$40,000 |
| After 27 years you have:
|
$80,000 |
| After 36 years you have:
|
$160,000 |
That's why it is so important to protect your 'nest egg'. If you allow
your money to grow you can double your savings every 9 or 10 years.
Someone who is 25 years old has 40 years to allow the magic of compound
interest to work. When you change jobs resist the temptation to
'cash-out', Take advantage of the 'roll-over' option.
Otherwise you'll be starting all over again from zero, and you can never
make up for those earlier years of saving.
When investing in your 401k retirement plan use the rule of 72 to remind
yourself of the power of compound interest.
