Inflation is something most Americans likely aren't thinking about on a regular basis, but it has a significant influence on their financial lives. Not only does inflation affect the prices of consumer goods;  the federal government also uses it as a benchmark in determining whether to increase contribution limits to qualified retirement plans or raise monthly Social Security benefits.

On an individual level, the inflation rate affects how much your retirement dollars are really worth. Over time, it can take a serious bite out of your nest egg. Understanding how inflation may hurt your retirement strategy is a must for ensuring that you have enough assets to last through your later years.

​​How Much Money Can Retirees Lose?

In terms of the actual dollar amount inflation can cost retirees, the numbers are startling. LIMRA Secure Retirement Institute constructed a model demonstrating the effect inflation could have on the average Social Security benefit over a period of 20 years. According to its research, a 1% inflation rate could swallow up $34,406 of retirees’ benefits. If the inflation rate were to increase to 3%, the shortfall would total more than $117,000. This chart illustrates the impact of varying inflation rates over time.       

This model assumes a moderate level of spending. For a retiree whose budgeted monthly spending is higher, inflation's impact is likely to be felt even more deeply. (See: 5 Signs You're Spending Too Much In Retirement.)

Inflation Diminishes Retirees’ Buying Power

The primary concern for retirees where inflation is concerned is how it affects their purchasing power. This is true even when inflation remains low because seniors are more likely to spend money on things that tend to increase in price, such as healthcare. According to the Centers for Medicare and Medicaid Services, per capita health spending for elderly Americans was three times that of a working adult and five times that of children in 2010, averaging $18,424 annually. (For more, see: Planning for Healthcare Costs in Retirement.)     

In 2014, the CMS estimated that healthcare expenditures increased by 5.4% overall. Over that same period, inflation averaged just 1.6%. That means that even when inflation is low, retirees will be hit harder than others because the costs that affect them most tend to continue to rise.

Low inflation becomes even more problematic when the Social Security Administration (​SSA)  doesn't issue an annual cost-of-living increase for those receiving benefits​. In 2016, for example, there was no adjustment because the Consumer Price Index​, which is used to calculate the inflation rate, remained unchanged from the third quarter of 2014 through the third quarter of 2015.        

Healthcare isn't the only item that can drive up retirees’ expenses. Housing, travel and supporting adult children also influence how much seniors spend. A survey from the Employee Benefits Research Institute found that 45.9% of retirees spent more in the first two years after they retired than they did in the years immediately prior. Twenty-eight percent of households were spending 120% of their pre-retirement income over that same period, which suggests that some seniors may be experiencing lifestyle inflation.       

​What Retirees Can Do to Curb Inflation’s Side Effects

While seniors can't directly affect the inflation rate, there are ways to minimize the shadow it casts over their retirement. Reducing housing costs, for instance, is a step in the right direction. Trading in a larger home for someplace smaller reduces the monthly outflow for mortgage payments (if you still have them) and can also lower other housing costs, such as property taxes, homeowners insurance and maintenance.

Another smart move is adding investments to your portfolio that are likely to increase in value as inflation rises. A real estate investment trust (REIT) or energy sector stocks, for example, are better positioned to see their value grow in tandem with the inflation rate. Just remember to balance stock investments with more conservative options, such as bonds, which are more predictable and tend to offer stable returns.

​The Bottom Line

Inflation can be a retirement killer but it doesn't have to be for seniors who take the time to develop a plan for combating it. Reducing spending, creating a realistic retirement budget and leveraging investments to take advance of price increases can all help to soften the blow inflation may deal to your long-term savings.
