That's like your opinion, man

. Being that they both have 401ks available at work, they're on the right track if they'll use them.
I don't know what they're getting right now from their employer, but say it's $200/mo each, then they only need to contribute $200/mo extra to hit their goal.
Inflation and increased wages will lighten that burden over time and they'll be happy they started when they did, imo.
PS. As I showed them with the time-value example, if they start saving in 10 years they'll have to put away over $1500/mo to reach the same amount at 65.
If they would have started 5 years ago, it would be only $375/mo.
You're welcome to your opinion. Mine is that starting early is paramount because the time is the key function and you can't get that back.
If our conversation inspires them to start an IRA, even if they can't put an amount away to equal $600/mo in total retirement contribution, I believe they'll be better off for removing the fear and mystique of an IRA and for starting earlier than later.
