I can’t believe how expensive tuition is in the US.
When my DS went to university to do his BSc, it actually cost us less than his previous school fees. When he did his Master’s degree IIRC it cost us 5000 GBP.
I know there are general rules of thumb but I think how much emergency fund is necessary or the best use for those funds depends on a lot of factors.
For ex., how much are your monthly expenses, is there another earner in the home, do you have a nice sized credit limit, do you have investments that can be easily liquidated, do you have parents or etc. who don't mind helping you out in a pinch, etc.
If you have any debt at all, or are in a heightened risk state I'd go for 9 months to a year liquid before investing beyond your standard 401k. Especially if you have children.
I agree about the cost of education in the US being ridiculous. I went to a state school and worked full time simultaneously in order to be able to pay it off by graduation.
I'm very lucky to now have a 6 figure income and no debt. That rarely happens and I wouldn't have been able to manage it if I had to be repaying school loans this whole time.
Interesting responses here. We have about 3 months and it's a bit anemic but we have no debt other than the mortgage which helps, I think. I'd like 6 months because like @winnietucker another car is on the horizon and I'd want to pay it off in full.
Debt free in our 30s with advanced degrees earning in the 1%. We live simply and have no debt apart from mortgages we choose to keep rather than exit other market positions. I don't think you should shy away from investments that can still be liquidated for extreme circumstances like job loss. Keeping cash in a bank is like paying the bank.
