I'm in my early 30s and never had more than a 100k income. We save 100% of my wife's income (~60-70k) and I also fully do a roth (6k) and my 401k match (4k). We currently have around 1.5m saved. We also live in a low cost of living area and have no kids. The house will be paid off and we'll have a bit over 3m saved by the time we're in our early 40s.
