I had savings. The difference is if I used my savings instead of my 401K it would have been difficult to "pay it back." But because there was already a mechanism in place to pay back my 401K (right out of my paycheck so I didn't even miss it), it was easier to do it that way. So I wound up eventually with the same amount of money in my 401K, plus 6 percent interest, but I wouldn't have necessarily paid back my savings because the same mechanism -- to deposit money out of my check straight to savings -- wasn't available at my work. I suppose I could have set one up privately, but why when there was already a mechanism in place?
In addition, my 401K was paid back through my paycheck before taxes were taken out. So that portion of my income wasn't taxed. If I set up a private mechanism to pay my savings account back, it wouldn't have been a pre-tax withdrawal like the 401k withdrawal was. It was a no-brainer for me. You can call it stupid all you want. Neither you nor Dave Ramsey will ever convince me that what I did was stupid.
