The power of compound interest
We often hear that compound interest is the eighth wonder of the world.
But how powerful is it, really?
In this article, we see how a higher interest per cent rate per year would mean the requirement of fewer years to double your money.
In Singapore particularly, there are unique products like the Central Provident Fund (CPF) which also help to support each individual’s endeavour to grow his or her retirement savings.
TL;DR: How many years do you need to double your money in Singapore?
The Beautiful Rule of 72
You can see in the chart illustrated above, where the black numbers on top represent the number of years , and the interest rate represents the rate of return generated from different financial instruments.
Take 72 divided by the rate of return to determine the time required
It is compressed into this simple formula you can see here:
Simply divide 72 by a constant rate of return, one will be able to derive the amount of time required for their investment money to double.
| Rate Of Return | Number Of Years For Investment Money To Double | Examples |
|---|---|---|
| 1 per cent | 72 | Savings |
| 2 per cent | 36 | CPF OA/ Bonds |
| 3 per cent | 24 | |
