How much to invest at present value?

How much should I invest today in order for me to get some value that reasonable to live in the coming future after taking into account the inflation and market value.

Should I invest RM10,000, RM20,000, RM30,000, RM40,000, RM50,000 or any figures that are relevant to my income capabilities.

Invest in ASB with 9% dividend every year for 30 years time :

RM10,000 = RM132,676.78

RM20,000 = RM265,353.57

RM30,000 = RM398,030.35

RM40,000 = RM530,707.14

RM50,000 = RM663,383.92

Or combine investment with my spouse in a separate account :

RM10,000 + RM10,000 = RM265,353.57 (Will generate income of RM1,990)

RM20,000 + RM20,000 =RM530,707.14 (Will generate income of RM3,980)

RM30,000 + RM30,000 =RM796,060.71 (Will generate income of RM5,970)

RM40,000 + RM40,000 =RM1,061,414.28 (Will generate income of RM7,960)

RM50,000 + RM50,000 =RM1,326,767.85 (Will generate income of RM9,950)
