In 2016, I turn 32. To celebrate, I am going to try to save my age, in thousands--$32k--by the end of the year. To achieve this, I plan on maxing out my 401k ($18k), plus matching contributions (appx 3.6k), maxing out my Roth ($5.5k) and making up the difference with contributions to my Vangaurd investment account (appx $4.9k). If I hit the goal early, anything in excess will go towards my dwindling SL balance or be added to Vanguard. Next year, goal will move up to $33k and so on.
I invite all those interested to join. For me, this savings goal is going to be a stretch and a challenge. The number and my age just happen to line up. Feel free to adjust the formula accordingly, e.g, age plus 10 or age minus 5, to set a goal that will be challenging but attainable for you.
