Budgeting

Zero-based budgeting in plain English: every dollar gets a purpose, so you know where your money goes. Here's exactly what that looks like inside Pocketwatch.

The one number that matters: Ready to assign

At the top of the budget page is a single figure called Ready to assign. It's the money that's hit your accounts but hasn't been given a purpose yet. Every dollar you have either sits in a category - assigned to a purpose - or in Ready to assign, waiting for one.

The math is the same as your kitchen-table version: income minus what you've assigned so far. New paycheck shows up? Ready to assign goes up. Boost the "Groceries" category by $200? Ready to assign goes down by $200. The goal is to land at zero - not because you spent it, but because every dollar has been assigned somewhere.

Categories are the source of truth

Once a dollar lands in a category, that's where you check whether you can spend. Not the checking balance. The checking balance shows what physically exists; the category shows what's spendable for this purpose.

Concrete example: your checking account says $1,800, but that's not your dinner budget. The number that matters is your Restaurants category - you assigned it $150 this month and have spent $90, so $60 is left. Dinner will run $40, so you're clear: you spend it, Restaurants drops to $20, and your other categories - Rent, Groceries, Emergency Fund - don't move. Pocketwatch shows what's available for this purpose, not whatever happens to be sitting in checking.

Moving money

Plans change. Pocketwatch lets you move money between categories in one click - pulling $40 from Travel into Restaurants because the dinner happened. The total stays the same; the tradeoff is recorded.

The act of moving is the budget. Zero-based isn't about being right the first time; it's about staying honest about what you actually chose to fund.

Rollover

At month's end, unspent category balances do not disappear. Whatever's left in Groceries carries forward into next month, on top of whatever you assign fresh. Build up $300 of slack in Restaurants over a quiet quarter, and that $300 is still there when an anniversary dinner shows up.

Categories that went negative carry the negative forward, too. The hole has to be filled before the category starts the month with available money again - Pocketwatch will nag you about it.

Income, refunds, and transfers

Income flows into Ready to assign. Refunds (money in, but from a previous expense) flow back to the category the original spend came from, restoring that category's balance. Transfers between two accounts don't touch the budget at all; the money is already accounted for - it's only changing location.

What the budget can't do

Pocketwatch's budget is a visibility tool, not an enforcement tool. Overspending a category is allowed (it shows red). The app doesn't block your debit card or refuse to log a transaction. Real enforcement happens between your eyes and the screen.
