Inflation is always with us, sometimes we don’t much notice, other times it can be a burden. Since I retired in 2010 inflation has caused my buying dollar to shrink by $0.39.
Retired citizens need a plan to deal with inflation. Beyond Social Security few retirees will have a steady income that adjusts for cost of living.
Before retirement is the time to establish your plan.
What you need is an income stream in addition to your regular retirement income whatever that may be. That supplement income stream is tapped when needed and until then is reinvested.
Interest and dividends can be good sources. Money market funds, bond mutual funds, dividend paying stocks are possibilities. You don’t have to be wealthy to do this and your need for additional inflation income is relative to your total income.

Interest was hard to come by for a 10 year or so stretch before last year. I used a dividend achievers fund during that time and did well with it. Now of course, treasuries, any cd, and high yield money market accounts can spin off cash as needed as well as dividend funds. You have to keep an eye on your yields and adjust as needed.

I retired in 2006, my buying dollar has shrunk by $0.49. My wife and I retired on two federal pensions from the old CSRS. We do not get SS, but thanks to the COLAs over the past 17 years, her pension is slightly higher than her income was when she retired in 2003, and my pension is about 92% of my income when I “punched” in ’06.
