Boomers are far more likely than any other group to be aware of price increases. When prices go up, they cut back on non-essential items and avoid impulse buys, with just 53% succumbing to them.
The harder mistakes to catch are the ones that look fine on paper but fall apart the moment you stop working. These are unquestionably the planning failures that will only reveal themselves after the paycheck ends and you're living off the portfolio. Recent data from Nationwide's Retirement Institute shows that 55% of people who retired in the last five years regret how they saved, and only 40% said they were on track with their original budget.
The 4% rule and most retirement calculators often just assume you are going to spend the same inflation-adjusted amount of money for the next 30 years. On the one hand, this is a simple and clean idea for managing finances, but it's also completely wrong.

At 2.16% annual inflation, purchasing power erodes slowly but steadily. Using the 4% withdrawal rule, $800,000 supports roughly $32,000 per year in initial withdrawals, adjusted annually for inflation. The critical nuance: withdrawing 4% during the first 7 years exposes you to sequence-of-returns risk. A 20% market drop in year one means selling assets at depressed prices, permanently reducing recovery potential.
