My spouse and I max out our respective 401(k)s first to reduce our AGI as much as possible and take advantage of matches. We also max out our HSA and dependent care FSA to further reduce AGI, pay for a tiny bit of day care, and provide savings for future health needs. I have an ESPP, so I max that out, as well, at 15% of my gross salary. I'm not eligible for Roth, so I use the back door method once per year at the end of the year.
I save around $500/mo for estimated taxes. I save roughly $600/mo for all of my known annual expenses. I save $200/mo for travel. I put $200/mo into a 529 for my daughter. Every other month I put $1,000 into a single dog of the dow stock (401ks and Roth accounts are in index funds)
Anything left goes into paying down my highest interest mortgage. I'm not in a hurry to pay down any of my mortgages, as they all cash flow and more than cover the cost of the investment debt. I have no consumer debt, otherwise my top priority would be to get rid of any consumer debt.
