For decades, retirement planning has assumed inflation would average around 2-2.5% annually, and financial planners built withdrawal strategies, income projections, and spending budgets around this number. Then 2021 happened, then 2022 happened, and suddenly the world saw inflation numbers hovering around 7%, 8%, and even 9% depending on where and how it was measured. Thankfully, inflation has cooled off from those levels, and today it's hovering right around 3%, rather than even higher, even though the Fed did promise a 2% inflationary number.
