Increase SIP with inflation!

SIP is considered as surplus savings allocated for long-term investment. However, with time one’s income & lifestyle also upgrades. Proportionately one’s expenses and aspirations expand. If one continues to invest the same amount, then it is highly unlikely that one’s financial goals will be adequately funded. In my view SIP should be reviewed annually and should be increased in ratio of inflation. So, say inflation is 6% then increase your SIP amount every year by minimum 6%. If one has more surplus savings, then one can increase it by more than 6% as well.
