If your employer is putting an amount equal to 13% of your pay into the account, why on earth would you need to put additional money into it? Unless maybe you have expensive chronic health issues? If you lose your unused contributions at the end of the year, I see no benefit to putting money in unless you expect to have some really steep health care expenses. Am I missing something?
Thanks for the response. No health issues, but possible maternity (so likely would hit the out of pocket max). 13% only covers premiums for myself and DH - it's not going as far as one would expect. It's also a volatile industry, so I have no idea if my job will exist in 5 years. That's part of why I was thinking about banking some of those employer contributions. Re-reading the docs, I shouldn't ever be in a place of losing my contributions - "If you do not set the maximum deduction amount higher than the cost of your insurance premiums and your Dependent Care expenses combined, you will never have to worry about forfeiting your employee contributions."
But I'm wondering if it's even worth getting into. Do out of pocket costs (deductibles, etc) balance out equally with tax write-offs? Or, would I get more bang for the buck getting reimbursed with pre-tax money? I'm just looking for the best way to work the system (my co-workers, on the same plan, are not very financially savvy.)

Ah, I didn't pick up on the fact that you're using the employer contributions to pay your insurance premiums. In that case, it makes sense to put in an amount that doesn't exceed your expected medical expenses (deductible, co-pays, and coinsurance). I'm not sure I understand the question you're asking in the second paragraph about balancing with tax write-offs vs. getting reimbursed with pre-tax money. You only get to deduct medical expenses to the extent that they exceed 7.5% of your AGI. So you're not getting any of that action unless you have a lot of health expenses. Which might be the case if you have a baby, but you'd need to weigh the expected expenses against your expected AGI to know for sure. Again, only the part that exceeds 7.5% of your AGI is deductible.
