Our 27 y.o. daughter is living with us but hoping to be able to afford to move out by next summer. She’s had a lot of expenses in the past 2 years (education courses and knee surgery) and used up most of her regular, non-retirement savings. She has to build that up again before she can get an apartment. She really wanted to move out this summer – our house is too small for 3 adults to live comfortably-- but we all get along well, so it’s not bad.
We are retired now and live on a modest budget; we do not have the luxury of supporting her. So we figured out a way for her to pay her share of whatever she uses. The idea is that after she moves out, our spending will be much the same as it is now; our budget will still work. And she will have a pretty good idea of what her COL will be, apart from her apartment and related costs.
Whatever we spend each month on food and other shared consumables (detergent, paper goods and such), she reimburses us for 1/3 of it at the end of the month. If we all go out to eat, she pays 1/3 of the total. She also pays 1/6 of the electric bill and 1/6 of heating oil. (She uses hot water, I cook more when she is home, etc.) We don’t charge her for things that won’t cost any less after she leaves.
She also pays for her own phone plan, everything to do with her car, her clothes, health insurance / health care, and any other purely personal expenses.
Chores: She cleans her room and does her own laundry. If she uses dishes, she washes them, and unloads the dishwasher if she sees the cycle is done. She helps with snow removal and mowing. If we ask her to vacuum or take out trash or whatever, she does so without complaint, but does not initiate. I think she is not a natural homemaker. But then, neither am I!
I’d love for her to cook dinner occasionally, just so she’d become more adept at it, but she doesn’t volunteer. She will do it if I ask, but I don’t tend to ask; I have the time to cook and her schedule has been busy. I was similarly disinclined to cook at her age, and when I moved out I had to learn in a hurry! She will, too. I’ve gradually compiled my own little “Mom’s cookbook” with all her favorite foods that I make, so she won’t have to go hunting for recipes unless she wants to.
