Kinda depends on what your bringing to the table…(as in income).
Our household income is north of 6 figures, but I would never spend over $100 on something without talking with the wife. She would do the same. Its out of respect - she would probably never say, “are you sure that’s a good idea?”, or “wow, that’s a lot of money”…or especially “no!”. Same for me. But its because we have total trust and respect for one another. If she were to one day say, “are you sure that’s a good idea”, I would table the purchase immediately, and we would talk about it.

Dude, finances is the number one destroyer of marriages (30 years a counselor). Get the trust established, get the respect going in spades, and be up front. It will pay off!

That being said - I probably spend $500 a year on “stuff” that is pleasing to me and maybe has little practical purpose. She does the same (Dooney and Burke purses, shoes, etc).
Some things are “toys” but also have practical purpose - tools, yard equipment, house furnishings, cooking stuff (I do most of the cooking). That’s probably another $500 a year.
I’ve tried to live by the formula of “invest/save 20, give away 10-15, and live off of 65-70.“. This spending falls well within that formula, after bills (the personal spending for both of us comes out of the 65.)

So, for a rough estimate, I guess you could say our “hobby spending” is around 1-2% of household income. However, I say again - that spending is done with full knowledge and transparency. 30 years of blissful marriage!

May you divine the proper path!
