Hello everyone, longtime reader here. My wife and I have an interesting work situation. Our salaries are modest, but we are provided with housing and food. Our only monthly bills are our cellphones and daycare. This means we can pretty effortlessly save huge amounts of our income, which we do (about 50% of our earnings). Recently, though, I've been wondering if there are ways to plan for retirement and think about savings that would be more specific to a situation like this. The general wisdom/advice out there always factors in costs for housing and food, meaning I'm always sort of trying to cancel those variables out when I think about how any particular piece of advice advice applies to my own life.
I think I recently discovered one good example, though I could be wrong. I was thinking about our life after this job, when we'd have to pay for our own housing and food again, and I started thinking about the fact that our draw from our retirement funds would need to be significantly higher than our current monthly needs. That led me to conclude that for us, perhaps, maxing out a Roth every year makes most sense, because it would give us access to tax-free money to cover that difference (we do not plan to retire unusually early). Does that make sense? Another simpler example is that I don't think we need quite as high of an emergency fund as some people might, since even if one of us lost their job, we'd still have housing and food covered as a family. Finally, another thing I've been thinking about is the possibility of over-contributing to our 401k's, given that we're able to save so much. How much should I worry about that?
Along these lines, are there other tweaks to typical retirement wisdom that anyone can recommend? I'd like to maximize the value in these relatively unusual conditions and also avoid pitfalls. Thank you!
