Calculating
your inflation-adjusted retirement income
|
Inflation
is one of the most important factors to consider in retirement
planning. It erodes the purchasing power of your retirement
savings, and thus needs to be taken into account in your planning.
Here you need to determine how much your retirement income
would be, adjusted for inflation.
In
our example, we know that the current value of James’
retirement income is RM120, 000 (from Step
2), and he has 24 years before he retires (from Step
1). The average inflation rate in Malaysia (from 1990
to 2001) is 3.3% - see chart below. Let us assume that the
average inflation rate over the next 24 years will be 5% per
annum.

A
retirement income of RM120, 000 today at an average inflation
rate of 5% would require James to have an inflation-adjusted
income of RM387, 011 per annum in 24 years time. This can
be calculated as:
| FV |
= |
RM120,
000 x FVIF (24 yrs, 5%) |

= |
RM120,
000 x 3.225 |
| |
= |
RM387,000 |

We will complete this article next month with Part
2 which will teach you how to calculate the total funds
you need for your retirement and how much you therefore need
to save per year.
