Priorities are more important than dollar amounts. You need, in this order food, shelter, running water, transportation, other bills (phone, internet, tv, whatever you choose to sign a contract for) and then with what's left you make a call. Personally I am making 2 house payments, 2 car payments, paying student loans, paying on credit cards, paying bills, eating well, and putting $25 a month into 2 separate accounts all after we tithe. One account is mine, one is my wifes. If we spend money on ourselves it comes out of our own accounts, if we do things together it comes out of the main account. It's hard to get much with 25 a month when that includes lunch if I don't take it to work, gas money for going places like the range or fishing, and even postage for stiff I send out through pay it forward thread, but every couple months I scrounge enough to make a small purchase. My next is primers. I also ask for reloading components for gifts on christmas, birthday, etc. This is on joint income of about 65k with just my wife and i. We do other stuff on the side, and that money goes into our personal accounts as well (if there's any time left), so I do small engine repairs, mow lawns, etc while she bakes the occasional birthday or wedding cake. It works out to where I grow my acount by about 10 or 15 bucks a month and she grows hers by about 20. This may change some now that she has all her bases covered and wants to shoot more. She has s glock 42, marlin 60, and 870 youth 20ga.
keep in mind though that my personal account covers guns, ammo, reloading, motorcycle parts, fishing gear, and any other toys I decide I need. My side money really gets stretched.
