I often hear of people saving 50% of after-tax income. That’s doable for some high earners.
I did it when single/we did it when we had two incomes.
Depends on the timing. I haven’t looked back but we could have when we finished 10 years of college with two double years. That with a paid off house and cars would make it doable.
If it’s not a goal for you(all other posters), then why worry about what other people chose ? I don’t see a savings rate as anything but a step toward another goal. If it is a goal for you, write a financial plan and start paring expenses.
