Every dollar
has a job.
LazeeFish is a free zero-based budgeting app — every dollar of income is assigned to a specific category before the month starts. Plaid bank sync handles the bookkeeping.
What zero-based budgeting actually is.
Zero-based budgeting (ZBB) is a method where every dollar of income is assigned to a specific category before the month begins. Income minus all allocations equals zero. Hence the name.
The point isn't to spend everything. Savings, debt payoff, and emergency fund contributions are all valid "jobs" for a dollar. The point is to make a deliberate decision about every dollar instead of letting it drift into whatever you happen to spend it on.
Most budget apps don't do this. They categorize transactions after the spend — which tells you where money went, not where it was supposed to go. That's a tracker, not a budget.
The mental shift: a budget answers "how much can I spend on this?" before you spend. A tracker answers "how much did I spend on this?" after. Both are useful, but only the first one changes behavior.
Same philosophy. Different mechanism.
Zero-based budgeting
"Every dollar gets a job before the month begins." It's the framework: pre-allocate, don't track-after.
The envelope method
"Put the dollars in named envelopes; stop spending when an envelope is empty." It's a way of executing ZBB physically (or digitally).
All envelope budgeting is zero-based, but not all zero-based budgeting uses envelopes. You could do ZBB on a spreadsheet, in a notebook, or in a fancy app. LazeeFish uses the envelope method because it's the most concrete way to make ZBB stick — there's a visible envelope balance ticking down as you spend, instead of a number in a column you might or might not look at.
Deeper dive: Envelope budgeting vs zero-based budgeting — the real difference.
Zero-based budgeting, automated.
Set your envelopes once.
Rent, groceries, utilities, fun money, savings, debt payoff. Allocate every dollar of monthly income into named envelopes. The total must hit your income — that's the "zero" in zero-based.
Bank sync handles the bookkeeping.
Plaid bank sync imports every transaction. Auto-categorization drops each one into the right envelope. You don't manually log $4 coffees.
Watch envelopes drain.
When an envelope hits zero, you stop spending in that category — or consciously borrow from another. The friction is the feature. Reports show patterns over time.
When zero-based budgeting works.
- — You end the month surprised by where money went.
- — You know you "should" save more but it never happens.
- — You're paying off debt and need every dollar accounted for.
- — You and your partner argue about discretionary spending.
- — Your income is variable and you need a tighter grip.
- — You already save what you want and never overspend.
- — You're a high earner with margin so wide that the precision doesn't matter.
- — You hate granular categorization and won't sustain the discipline.
- — Your finances are so simple (one income, fixed expenses, automated savings) that a tracker is enough.
The other zero-based options.
YNAB pioneered modern zero-based budgeting software with their "give every dollar a job" framework. It's genuinely good. The pedagogy is excellent, the community is healthy, and the workshops have helped a lot of people.
It also costs $109 a year. If you want zero-based budgeting and you'll pay for the structure, YNAB is the right purchase. If you want the same envelope discipline without the subscription, that's why LazeeFish exists.
Other apps marketed as "budgeting apps" — Mint, Monarch, Simplifi, Copilot — are tracking apps. They categorize after the fact. They're useful, but they don't enforce zero-based budgeting. If "every dollar has a job" is what you actually want, you need YNAB or LazeeFish.
Zero-based questions.
What is zero-based budgeting?
A budgeting method where every dollar of income is assigned to a specific category — savings, rent, groceries, debt payoff — before the month begins. Income minus all allocations equals zero. The point is to make a deliberate decision about each dollar instead of letting it drift.
Is the envelope method the same as zero-based budgeting?
They're closely related but not identical. Zero-based budgeting is the philosophy: every dollar gets a job. The envelope method is one implementation — you put dollars into named envelopes and stop spending when one is empty. LazeeFish uses the envelope method as its way of executing zero-based budgeting.
Is LazeeFish a true zero-based budgeting app?
Yes. The core flow is: enter your monthly income, allocate every dollar to envelopes until your remaining balance is zero, then track spending against those envelopes. No "unassigned" budget category sitting in the background — if you don't allocate it, the system flags it.
Is YNAB a zero-based budgeting app?
Yes — YNAB pioneered modern zero-based budgeting software. LazeeFish uses the same envelope discipline with the same Plaid bank sync, but is free. YNAB has a more polished education system; LazeeFish has the price ($0).
What if my income varies month-to-month?
Zero-based budgeting still works — you just budget the money you actually have, not the money you might earn. When new income lands, you allocate it then. See: Budgeting with irregular income for the full pattern.
Is zero-based budgeting overkill for casual budgeters?
It can be — if you're already saving what you want to save and not stressed about money, a tracking-only app is fine. ZBB is for people who keep ending the month wondering where the money went. The act of pre-assigning every dollar is the intervention.
