Well, that's depressing. Both because the average retirement savings rate is so low overall and because my savings total is more appropriate for someone a decade younger.
That said, I've been hoarding cash and stocks to pay off my house, and the goal is within sight in less than 18 months. I feel like having no house payment (and no debt otherwise) will have a much greater effect on both my ability to save as well as my sense of security.
When my only regular non-discretionary expenses are food, utilities, insurance, and property taxes, I'd be able to live off of a minimum wage job indefinitely if I needed to. Not that I will, but it's nice to know a corporation no longer owns me.
Yeah, owning your house certainly has value, regardless of the financial impact. Life is all about trade-offs, and it's why I have an e-fund despite investing probably having the better expected outcome.
And the average savings rate is also depressingly low. I'm actually closer to an average retiree than a young hire in terms of total savings, yet I don't feel anywhere close to retirement (and I'm retiring fairly lean @ ~$50k expenses). I just don't see how it works for the average person, and maybe it doesn't, and people just have to drastically adjust expectations in retirement.
I think it's a decent metric. The important thing to know is that no single guide is going to work for everyone, everyone has to adjust it to their situation.
Me, for example, I have a 401K balance of zero. Every time I leave a job, I roll that over into my IRA, then into my Roth. I just like having control over my accounts; 401Ks have too many restrictions. But to each his own.
Same, I convert to Roth a little at a time to control taxes. I'm in the 12% bracket, so I convert up to the end of that bracket at the end of the year.
That said, 401l does have some advantages over an IRA, such as backdoor-Roth compatibility, legal protection from lawsuits, and the loan option. I don't need any of that, so I roll out ASAP.
So for those kinds of metrics, I just use the aggregate of all of my retirement accounts, so IRA, 401k, HSA, and taxable brokerage. I'm assuming most people only use their 401k or aggregate as well.
