The Best Free Budget Tracker for Zero-Based & 50/30/20 Planning
Write the plan once; the spending fills itself in from your own ledger. Zero-based budgeting and the 50/30/20 rule running side by side, in any currency, with no bank login and no subscription.
CalculatorAI
Budget Tracker
The plan carries forward. A new month opens with last month in it, and every monthly line already has its row.
You record a purchase once. The budget reads your expense ledger instead of asking you to retype it.
One budget, several currencies, converted at live rates without ever rewriting what you stored.
Rollover works in both directions, so an overspend follows you instead of quietly disappearing.
What it actually does
Zero-based, to the last unit
Give every unit of income a job until nothing is unassigned. The dashboard shows what is still waiting, and says so in your currency.
50 / 30 / 20 at the same time
Plan zero-based, and the analytics tab scores the same month against needs 50 / wants 30 / savings 20. Two methods, one budget, no double entry.
Actuals from your ledger
Spending recorded in the Expenses Tracker lands against the matching budget category on its own. A figure you type stays yours and is never overwritten.
Rollover, both directions
What you didn’t spend last month is available this month, per category and overall. What you overspent follows you too. Switchable.
AI copilot
It has read your budget before you ask
The assistant sees this month’s plan against what actually happened — per category, per group, converted into one currency when the budget spans several. It answers from your figures, not from generic advice.
What it does without being asked
Flags the group that has run past its plan while there is still month left to fix it.
Notices planned income you have not given a job to yet — the zero-based failure mode.
Puts a budget line in the weekly email, with one concrete next step.

Where it wins
- The plan carries forward. A new month opens with last month in it, and every monthly line already has its row.
- You record a purchase once. The budget reads your expense ledger instead of asking you to retype it.
- No bank credentials, ever — which also means it works in countries no aggregator covers.
- One budget, several currencies, converted at live rates without ever rewriting what you stored.
- Rollover works in both directions, so an overspend follows you instead of quietly disappearing.
- Import what you already have: a spreadsheet screenshot, a bank statement, or a photo of a budget on paper.
- CSV export is free on every plan and carries every field. No watermarks on anything, ever.
Where it doesn’t (yet)
- No automatic bank sync. That is deliberate — we never ask for banking credentials — but it does mean transactions arrive from the expense ledger, not from your bank overnight.
- No shared or household budget yet. One account, one budget; a partner cannot edit alongside you.
- No native mobile app. The tracker is built for the phone browser and works there, but it will not appear in an app store.
- The envelope flow is simpler than YNAB’s. If you want strict rule-based assignment with a long ledger of moves between envelopes, that tool goes deeper.
Budget tracker questions, answered
How zero-based budgeting is calculated, where the actual figures come from, what happens to a month’s leftover, and what we do with your data.
Is this budget tracker really free?
Yes. Zero-based budgeting, the 50/30/20 meters, the payment calendar and CSV export are free on every plan. Pro lifts the line-item and category limits and unlocks the AI budget copilot.
Do I have to connect my bank account?
No. There is no bank login and no credentials are ever requested. You enter planned and actual amounts yourself, or hand them over from the Expenses tracker — which keeps the tracker usable in countries no aggregator covers.
What is the difference between zero-based budgeting and the 50/30/20 rule?
Zero-based budgeting assigns every unit of income to a category until nothing is unallocated. The 50/30/20 rule is a coarser split — 50% needs, 30% wants, 20% savings and debt. The tracker runs both at once: you plan zero-based and the analytics tab scores you against 50/30/20.
Can I budget in more than one currency?
Yes. Every line item and category stores its own currency, and totals are converted at live rates into whichever currency you are viewing. The stored value never changes, so a salary in one currency and rent in another stay accurate.
Can I export my budget?
Yes, to CSV, on any plan, with every field the form collects. Exporting your own data is never gated.
Start with the month you are in
Open it, import the budget you already keep somewhere, and let this month fill itself in. Free, no card, and your data stays visible whatever you do later.
