Just realized something about Social Security that caught me off guard. Most people know 62 is the earliest you can claim, but the actual hit to your benefits is way bigger than I thought.

If you file at 62 instead of waiting until 67, your monthly checks get cut by 30%. Not a small reduction. So if you'd get $2,000 a month at full retirement age, claiming early drops it to $1,400. That's permanent too—it doesn't go back up later.

The math gets even more brutal the more you were entitled to. Someone eligible for $2,500 monthly at 67 ends up with $1,750 if they claim at 62. The bigger your benefit, the bigger the dollar hit.

Here's the thing though—it's not always the wrong move. If you've got serious health issues or you're confident you won't live to your 80s, claiming early might actually make sense. You'd collect more total money over your lifetime. But that's a specific situation.

For most people though, before you make this call, you really need to sit down and calculate whether you can actually handle a 30% income cut for potentially decades. If Social Security is your main retirement income, that reduction could be rough. If you've got solid savings to lean on, it's less painful.

I've been thinking about who pays for social security and how the whole system works—it's basically current workers funding current retirees. So there's definitely incentive for the system to encourage people to wait longer and collect less per month overall. That said, the decision should be about what works for your specific situation, not what the system wants.

Worth running the numbers for different scenarios before you lock anything in. Even filing at 64 instead of 62 makes a meaningful difference.
