I was very excited this past week to have made my first contribution to my Roth 401K. At first I wasn’t sure if I wanted to dedicate all my contributions toward the Roth. By contributing to the Roth 401K rather than a standard 401K, I’m effectively trading taxes tomorrow for taxes today.
I don’t have a view per se on what taxes will be for me when I retire versus what they are now. Will taxes be higher? Will I be in a higher income tax bracket? Those are all questions that I cannot answer with any certainty. However, the advantage of the Roth is exactly because of those uncertanties.
I compare the Roth 401K/Regular 401K debate to fixed rate mortgage versus an adjustable rate mortgage. A fixed rate mortgage is not inherently better, but it gives price certainty. That’s exactly what the Roth 401K does, it give me price certainty on what I pay in taxes.
I max out what I contribute and as result I don’t have to make any tradeoff when it comes to how much I can contribute. If anything because the amount I can contribute to either a Roth or Regular 401K is the same nominal amount (15,500), I can effectively contribute more to the tax sheltered account as I pay in after tax dollars. The one group of people who I think might be better off contributing to a standard 401K are those who cannot afford to contribute to get the full company match.
Let’s say for example say I make $100, and my marginal tax rate is 25%, and my budget is $70. I would be able to contribute $5 or 5% towards a Roth 401K. Let’s also say my company matches the 1st 6% of my salary in terms of contribution. By contributing to the Roth 401K, I would fail to max out my company match. However if instead chose to contribute 6% towards a regular 401K, I would still be left with $71.25 in take home pay, and receive the full company match.
