What I Wish I Had Known Before Retiring: The Financial Regrets I Hear Most Often

Claiming Social Security at 62: The Regret That Never Goes Away

Of every financial regret I heard from retired clients, this one came up most often. And it's the one that's genuinely hard to fix once made.

Claiming at 62 gives you 30% less monthly income than waiting until 70 (for those born 1960 or later). On a $2,200 PIA, that's $1,540/month versus $2,728/month. Every month, for the rest of your life.

The clients who regretted this decision almost universally said the same thing: 'I wanted to get the money back that I'd paid in.' Or: 'I thought I should take it in case the rules changed.'

The 'get your money back' framing misunderstands Social Security. It's not a savings account with your name on it — it's longevity insurance. You're not 'getting back' contributions; you're receiving an annuity whose monthly payment is set by your claiming age and never adjusts upward.

At 78, the difference between $1,540 and $2,728 is $1,188/month — $14,256/year. At 85, the retiree who claimed early has given up roughly $130,000-$170,000 in cumulative lifetime income versus the one who waited. That's not recoverable.

Underestimating Healthcare Before Medicare — and After

The second most common regret: not understanding how expensive healthcare would be. This hits hardest in two windows.

**Before Medicare (62-65):** Many people who retire early expect COBRA to bridge the gap — and are shocked when COBRA runs out at 18 months and they face full-cost ACA premiums. A couple in their early 60s might face $1,400-$2,000/month in ACA premiums at full cost. Over three years before Medicare, that's $50,000-$72,000 that wasn't in the plan.

**After Medicare enrollment:** The common mistake is assuming Medicare is essentially free. Part B premium in 2026: $190.40/month. Add a Medigap supplemental plan: $150-$250/month depending on plan and state. Part D drug coverage: $30-$100/month. Dental and vision (not covered by Medicare): $1,500-$3,000/year out of pocket or via separate plans. A couple on Medicare might spend $700-$1,200/month on healthcare-related costs after Medicare begins.

Fidelity's healthcare cost estimate for a 65-year-old couple: $315,000 over retirement. That number rarely appears in retirement projections.

Ignoring the RMD Buildup Until It Was Too Late

Required Minimum Distributions were invisible to most clients until they started. Then they were surprised — and frustrated.

Here's what happens: a couple defers all their savings into traditional 401(k)s and IRAs for 30+ years. At 73, RMDs begin. The calculation: $1,200,000 / 26.5 (IRS uniform life table factor at 73) = $45,283 in required distributions — taxable income, whether they need it or not.

If they're also receiving Social Security ($45,000/year combined) and a small pension ($12,000/year), their taxable income is $102,283. They're in the 22-24% bracket. Medicare IRMAA surcharges kick in above $212,000 MAGI (for married couples), but the IRMAA cliff for single widowed spouses at $106,000 can trigger an additional $700-$2,000+/year in Medicare premiums.

The regret: 'Why didn't I convert some to Roth when I retired at 65 before RMDs started?' The answer, usually, was that nobody framed it as an opportunity. The eight-year window between retirement and RMD start (65 to 73) is a tax planning window that closes permanently once RMDs begin.

Spending Too Little in Early Retirement — and Regretting It Later

Less common but worth naming: the retiree who was so focused on not running out of money that they spent their early retirement years in austerity and later deeply regretted it.

Retirement spending follows a predictable pattern. The 'go-go' years (65-75) are when travel, hobbies, and experiences are most accessible. The 'slow-go' years (75-85) bring reduced physical capacity. The 'no-go' years (85+) are often sedentary.

A 70-year-old with a successful Monte Carlo analysis (90%+ success rate) who has been spending $48,000/year on a $72,000/year safe spending capacity has forgone $24,000/year in experiences for five years — $120,000 in nominal terms, often representing a decade of international travel or other irreversible experiences.

The analysis isn't 'spend more regardless.' It's 'understand your actual spending capacity based on your numbers, and make the choice deliberately.' The goal of the analysis is to see the number clearly — not to give permission to overspend, but to prevent fear-based underspending that produces regret.
