My parents come from a conservative, traditional background, so my mother left work to be a housewife and stay at home mother while my father worked. She isn't in great health and hasn't worked since she left her home country 30 years ago, so finding a job has been nearly impossible. My father makes a good amount but he mostly gives her money to pay for household needs and she's embarrassed to ask him for personal needs and wants because he doesn't treat her that well.
My father is 63 and I'm worried that if he retires things will become more difficult for her because he does not have a large retirement savings, and I want her to have something of her own to fall back on.
My 2 siblings and I are all in our 20s but single and well-off financially and so we each give her an 'allowance'. Between the 3 of us, and whatever my father gives her, she has around $500-$700 each month to spend on herself.
The problem is that she feels that she's not putting the money to great use. She mostly spends it on shopping or going out to eat and once in a while visiting her family overseas. I have no problem with this and I want her to have money to enjoy herself with, but I would also like her to have some kind of savings or investments which can be a security blanket for her within the next few years.
I wonder what the best option would be for her. Considering that she's almost 60, I don't know if starting something like a Roth IRA would be beneficial or if I should just go with a regular savings account?
I currently don't have any real living expenses except for food as my company pays for all my housing and transportation, and I'm single with a good amount of savings, so I'd definitely be willing to contribute more to her. I just want to know what the best plan would be so that it can really benefit her in the long run.
Any advice is appreciated.
