My husband's open enrollment at his work ended just before mine started, so we had only estimates to compare.

Since he is one of those lucky people that NEVER needs a doctor and I am one of those that goes all the time (thyroid disease, etc), we figured it made sense to have him go through his insurance since he'd never make the deductible.

And I will put my daughter & myself onto my employer's insurance.

I also am planning to utilize every extra benefit that I can. This includes Medical coverage that also provides a contribution from my employer to my HSA of $1500. I am contributing $2500 to the HSA myself.

I am also utilizing the Family Care HSA. Daycare costs will be more than the $5k maximum it allows, so the HSA will be fully utilized in 2016. Work contributes 50 cents to every dollar, so I will put in $3333.33 over the course of the year and they will put in $1666.67. So basically - free money & pre-tax funds to use toward day care!

I am keeping my 401k contributions at 14%, with the 6% company match, that's 20% of the salary.

The increased costs for medical for the baby, increased HSA contributions and the daycare FSA will significantly decrease my take home pay, but in the long run, the savings will be worth it!
