How much does it cost to raise a family of 5?

I think it’s doable. Plan your finances properly before you quit. If you feel it won’t be enough to support a family of 5, you can consider taking up courses to supplement doing part time jobs. You can also do pet sitting, baby sitting, learn how to do diaper cakes, bake, do sandwiches, learn how to do massages, etc. Maybe you can have a bank account that pays all your house bills so that you don’t touch that money. An account for food. A money pouch for misc whatnots. Give yourself 1-2 years at least to keep these savings aside before you quit your job.
