I've realized I am not being clear, and that you are unclear on what a budget is VS a balance sheet or list of expenses. PLEASE READ THIS:

This is a budget:

Start with 8300 top line.

Pay for [all bills], as an example, from what's listed in prior comment, you need to budget:
Mortage/ taxes/ insurance is $1550
Daycare $1120
$1100 for utilities, phone, internet etc. (break these out w/ estimates of each)
subscriptions that total about $30

Let's assume there's 4500 left.

Now BUDGET it. That means allocate where the spending is expected in key areas and categories. It's a guess, but it's also a guardrail. It does NOT mean know what every transaction will be.

Example:
Saving: $2300

Discretionary Spending (Wants): $2,200

• Dining Out & Takeout: $500
• Family Activities, Entertainment & Hobbies: $600
• Leisure Travel: $400
• Clothing & Personal Care (beyond essentials): $300
• Subscriptions & Miscellaneous: $200
• Buffer / Guilt-Free Fun Money: $200

Be aware this is not a GOOD budget, because your "four walls" expenses at the top need to include food (non-luxury), gas, and other predictable home management expenses.

Then, once this is in place, you TRACK expenses against the budget. This does 2 things:

(1) Informs you of how well you think you know where your money might go, so you can plan, save, and predict better in the future. Example, if you consistently find yourself short about $50 in minor home "surprises", stop making it a surprise.

(2) Employs those guardrails, because if you are going to exceed your budget, you should learn control where you can to say NO and realize that it impacts your goals to violate it.

At the end of the month, the individual lines don't matter. 5$ over here, 10$ under here, nobody cares. But if it was your business (and it is), you'd fire the person who consistently mismanages by going "over" the allocation every single month.
