$400? LOL good lord. Currently I keep about 4 months expenses in a standard savings account to cover any type of life emergency. I'd prefer to bump it to 6 eventually. It ****ing blows my mind how undervalued emergency funds are in our society these days. Couple of relevant stories...
1. Right now the Canadian government is under fire because it rolled out a new payroll system that has been a catastrophic failure. For months public servants have had issues with pay cheques, including missing payments all together. For some who received promotions their increased salary hasn't been paid yet while in extreme cases there are people who haven't been paid in a couple of months. It's all technical and eventually will be sorted. I know some people like my girlfriend are already beginning to see backpay show up on their pay cheques.
Now, the situation is ridiculous and an embarrassment. Anyone impacted certainly has the right to be angry. However, there are numerous commentators on Reddit who say things like, "This is our livelihoods! One pay cheque missed and I would have to go to a food bank!" Others report friends who are missing increased promotion salaries (ie. got promoted from 50k to 60k but the extra income isn't being paid yet) and are now going into debt to cover the missing money they 'depend' on. I see statements like, "People plan their expenses around expecting X salary every single month!" and when emergency funds are brought up people claim that a situation like this is unexpected and thus can't be planned for.
Retards. That is the exact purpose of an EF. You don't build it for things you expect to happen (well, you can but that's not the sole purpose) - it's to guard against the unknown. These people who are owed a month of backpay could have just as easily lost their jobs or became too ill to work or had a major uncovered loss to their home, etc. and they'd be just as ****ed. The notion that public servants - who by the way are paid way above the national average - are one pay cheque away from food banks is ****ing insane. I have people on my Facebook with decent incomes who often post (almost brag) about living pay cheque to pay cheque.
Then you get people who argue leaving money in a savings account doing nothing is foolish. Obviously I seriously value passive income and investing, but these guys actually argue that tapping into stocks to cover unexpected expenses is a fine alternative. Do they not realize that if the bad thing that happens to you is a job loss during a recession, selling stocks actually compounds your lost wealth?! Jesus.
2. My girlfriend's dog is sick. He's a bit older and has a few lumps on his body that need to be removed, including one under his eyelid that would eventually blind him if nothing is done. Completely unexpected expense. Quote from vet is about $2000 for surgery. A lot of money. My girlfriend has a few months of expenses available as well - so guess what? No food bank for her. I've offered to chip in a bit just because he's my dog too now, but she could/would cover the entire thing out of pocket and be just fine ... because she smartly planned for the unknown.
An emergency fund is literally one of the most important components of a sound personal finance strategy. Regardless of income or life circumstances. Not being prepared for the unknown almost always has negative rather than positive consequences, and those consequences can often impact your financial well-being for months or even years after the event.
TLDR - Stop willingly living pay cheque to pay cheque and save some ****ing money, OK?
