Here's another thought. No matter what your medical needs are expected to be, you may want to contribute the maximum to your HSAs until you become ineligible due to Medicare or other insurance changes. If you have access to investment options besides simple interest, the HSA may be preferred over a 401(k). Here's why:
1. when you turn 65, you can withdraw from an HSA for any reason and pay regular income tax with no penalty, just like an IRA, but if you pay for medical expenses, it's tax-free. So it's like a 401(k) with a bonus tax-free option.
2. employee contributions are exempt from FICA and Medicare tax, but you pay FICA and Medicare tax on your 401(k) contributions, so HSA contributions go a little farther and save you a little more in taxes.
About 2/3 of my HSA (excluding what I might need in one year) is invested in a mutual index fund that gained 20% last year, and I intend to max out my HSA every year that I can, before maxing out other options.
