Inflation — the rise in consumer prices — is a slow erosion of your money over time. Before 2021, the United States hadn’t seen annual core inflation much above 3% for the better part of 25 years, says Michael Ashton, managing principal of Enduring Investments, a consulting and investing firm in Morristown.

So the 7.5% spike seen over the past year in the costs of fuel, used vehicles, groceries and just about everything else is the kind of sudden and systemic rise that can give a jolt to most peoples’ everyday spending.

Ashton also says that the COVID-19 pandemic stimulus checks and tax relief, combined with the reopening of the economy, fed consumer demand but didn’t replace product inventories. The result: shortages that lead to higher prices.

“Having supply chain difficulties is part of what inflation looks like,” Ashton says.

With inflation chipping away at your spending power, how can you protect yourself?

— Trim discretionary spending, voluntary spending in categories like entertainment or travel, by just 5%. This is one of those incremental changes that isn’t that difficult to do and goes directly to your personal bottom line.

— Don’t delay a major purchase; prices will likely rise.

— Shop strategically. Buy more generic brand products and prescriptions. Save on necessary expenses by using coupons and store loyalty programs. Use membership cards (like Walmart+ and others) to pay 5 cents less per gallon for gasoline.

— Eliminate any fees you pay for credit cards or bank accounts (late fees, monthly or annual service fees, ATM fees, etc.). Many banks are waiving such fees and credit cards often have fee-free options.

— Renegotiate your cable, streaming or cell phone bill for any possible savings.

“I can say from my own personal experience – it’s amazing how easy this is,” Ashton notes. He says that every time he would call his cell phone provider, it would offer him a plan that was far better than his current one. “And it doesn’t happen unless you call,” Ashton adds.

He now makes a habit of calling once a year and asking, “What’s the best plan you have and should I be on that?”

— Reduce the number of subscriptions you have, even if by just one.

“You should do an audit of those from time to time because sometimes they sneak in a price increase, and it just shows up on your credit card,” Ashton says.

— Search for financial institutions that pay higher interest rates than you are earning now (if you are earning anything at all). Online banks and credit unions often offer high-yield savings accounts that sweeten returns, especially as interest rates rise.

— Perhaps the most powerful idea of all: Ask for a raise. If you haven’t received an increase in salary in a few years, you’ve likely experienced what amounts to a pay cut because of inflation, Ashton says.

Another inflation-fighting idea: Series I savings bonds. They were created specifically to protect consumers’ purchasing power against inflation, says Zvi Bodie, professor emeritus in finance at Boston University. Bodie holds a doctorate in economics from the Massachusetts Institute of Technology and has become an avid proponent of I bonds.

I bonds rates are keyed to the rate of inflation, which lately has been over 7%, he notes. They are a perfect safe haven for near-term savings. And not a bad addition to your long-term nest egg, too.

A minimum investment i n I bonds through TreasuryDirect.com is only $25, and an individual can put up to $10,000 annually into the savings bonds with electronic purchases. The bonds pay fixed interest plus the inflation rate, adjusted twice per year.

You can withdraw your savings without penalty after one year, but if you cash them in before five years, you’ll lose the last three months’ worth of interest.

“So what you get is essentially a savings account that can’t go down, and that’s going to go up with inflation,” Bodie adds. “Do I need to say more?”

Inflation hit a 7.5% national average in January, but that’s not likely to be your inflation rate, says Ashton.

You may consume different items than the average person and you may not live in an average place, so your particular rate of inflation quite likely varies from the average, according to Ashton.

So, rather than agonizing over a single number as a spending power loss to recoup, use the small money moves above to improve your financial position slowly but surely.
