I think we can ignore the pension income for now. The question is how to get from here to 65 without exhausting the $1.1m savings. Here's where you should fire up cFireSim or Firecalc and start running scenarios
Option 1: retire now
Assuming you spend $6k/mo for the next 25 years, both cFireSim and FireCalc give a 50-60% chance of success. That, however, is a worst-case scenario. Dropping your monthly spend to $4,500 increases your chance of success to 85% or so. Keep in mind, also, that kids are more expensive as teens. They eat more and typically have more expensive activities/hobbies.
Option 2: go part time until age 65
Let's say that you quit working full time, and take on work that brings in....oh, let's say $30k/year, and you keep spending $72k (worst-case scenario). cFiresim and FireCalc both give you a 100% success rate.
Option 3: keep working full-time for a few years
If you worked for 5 more years, contributing $24k each year, and getting 7% return, that'll leave you with $1.68M, which will only have to cover 20 years' worth of expenses. Even at your highest spending rate, you get 100% success.
If you worked for 3 more years, with the same assumptions, you get an 87% success rate at a $6k/mo spend, and 100% success at $4500/mo spending
