How Much of Your Pre Retirement Income Can You Replace if You Start Saving 25% Today?

A lot of people say, you know what, I think I got enough in there. Let's just focus on other things I need to be doing in life right now. That is a mirage. You still have a long window where you can begin building assets for your future. A 40 year old that starts today saving 25% of their gross income by the time they get to retirement at 65 would be able to replace 58% of their pre retirement income for a 45 year old. Even if you just start saving today, you'd still be able to replacing 39% of your pre retirement income.
