Firstly, save up for the emergency fund, which is three to six months of expenses, and set it aside. After that, least 15% of your combined gross household income should go towards your retirement, once all debt is cleared.
If only one of the partner works, you still can save up for retirement using a Spousal IRA, provided a joint tax return is filed. For details, you can consult an investing professional.
It is also a good idea to clear up the old 401(k) accounts which are hanging around from the old jobs and put one's investments in order.
