It's meh, but put it in saving account with 3%p.a. mean you're getting 2.5k per month from doing nothing. It's meh money as well, i know, but you won't goes hungry in a stable economy at least.
Well, that's the issue. The dividend of 2.5k from investment obviously won't allow a comfortable living and should be treated as something extra. It's pretty ridiculous to live in a big city with rent higher than the dividend and without job lol.
If you try to retire on $1M you're going to end up in a medicaid facility. Interest rates are high right now, so $1M in the bank may get you as much as $5,000/mo if you're lucky. This is $60,000/yr and can be supplemented with social security to allow a person to live well enough at today's cost of living.
However, inflation is a constant and is ideally restricted to 2-3% per year. This means that every year you live after you retire, your spending power is reduced by at least 2%. So even if interest rates stay high (they won't) then by the time you hit 85 your $60,000/yr will feel more like $24,000. This will still be supplemented by social security, but you will also find that your needs are increasing by this age and you will likely need to start using your savings to pay a lovely nurse or two to help with, well, everything. In-home care and even nursing facilities are quite costly and will eat away at your savings, so if you only have $1M you better start dying soon after needing them.
This all assumes best-case-scenario. It doesn't account for runaway inflation rates, pandemics, recessions, catastrophic events (it's not uncommon for the elderly to accidentally set things on fire), or other possibilities that can take a bite out of your retirement savings.
When your money runs out you won't be kicked out on the streets, thankfully. But a medicaid facility in the US can be nearly as dangerous for the elderly.
You're ignoring that your balance will increase over time through interest and stock gains. I believe this is historically around 8%, exceeding inflation.
It's wild when you watch a show like 'The Rockford Files' because Jim et al were always using specific sums when they talked. Someone boasting about owning a $1 million house in Beverly Hills or spilling their guts for $20 is pretty mindboggling.
