I finally got rid of all of my student loans and car loans just a few years ago. So now my only debt is my mortgage with a 2.25% interest rate so I lucked out on that. Also I live in a house that is well within my means.
So my savings rate was about 5% for about 12 years but it finally jumped to 30-35% for the last 3 years or so. I basically have kept lifestyle creep out for a little while although I think my wife is ready to take a step up in vacations and those things now.
If I can somehow manage to keep the savings rate at 30-35% over the next 7-10 years then I should really be able to loosen the strings a bit when my kids are all teenagers/college students.
