Been thinking about this lately and it hit me how many people assume 70 is the magic number to retire at, but honestly it's way more complicated than that.

Like, I've noticed a pattern with people who try to retire at 70 without doing the homework first. They have no clue what their actual expenses will be. You need to sit down and actually calculate your post-retirement lifestyle costs, not just guess. The difference between what people think they'll spend and what they actually spend is wild. Commute costs disappear but then Medicare deductibles and long-term care insurance show up. Most people don't account for that shift.

Then there's the debt situation. If you're carrying high-interest debt into your 70s, that's a massive problem. People don't realize that debt tends to spiral when you don't have stable income anymore. And honestly, even a mortgage in retirement? That's rough. Your income shrinks but housing costs stay the same or go up. Most people can't actually afford to retire at 70 with a mortgage hanging over their head.

Healthcare is another thing everyone underestimates. Medicare sounds like it covers everything until you actually look at the gaps. Premiums, deductibles, copays, dental, vision, hearing aids - that's all on you. Long-term care? Tens of thousands per year and Medicare doesn't touch it. You need a real strategy here, not just hope.

If you're supporting a dependent or family member, the math gets even messier. Your retirement funds have to stretch further and you might genuinely need to keep working.

But here's the thing - some people at 70 shouldn't retire because they actually don't want to. I know people who could easily retire at 70 but they love what they do. The social aspect, the purpose, the professional identity - that stuff matters more than people think. Some even shift to part-time work or find something they're passionate about instead of the grind they've been in for decades.

Bottom line: don't assume 70 is the target. Do the actual math, clear your debts, plan for healthcare, and honestly check in with yourself about whether you even want to stop working. Those are the real markers.
