Build a budget that survives a real month, not just a spreadsheet that looks good on day one
Budgeting.id builds a zero-based monthly budget from your take-home pay, fixed expenses and savings goals, and shows you exactly how it compares to the 50/30/20 rule and the envelope method. We are based in the United States, we are not a bank, and we never see or move your money — we just help you see where it is going.

Zero-based budget builder
Give every dollar of your take-home pay a job — housing, food, transport, utilities, debt and everything else — and see exactly what's left.
Assumptions this uses
- Uses monthly take-home pay, not gross income before taxes
- Assumes the amounts entered are realistic recent averages, not aspirational targets
- Treats savings as a category you assign, not an automatic leftover
- Does not include annual or irregular expenses unless you divide them into a monthly amount first
- A planning tool, not a live view of your actual bank balance
Limitations: Does not connect to your bank accounts and cannot verify actual spending against these categories.
Runs entirely in your browser.
A budget category with $0 left is a feature, not a failure
In a zero-based budget, every dollar of take-home pay gets assigned somewhere — needs, wants, savings or debt payoff — so hitting $0 left over at the bottom of the plan means the plan is working, not that you've run out of money. If a category runs short partway through the month, that's useful information about where your estimate was off, not a reason to abandon the whole budget.

What is zero-based budgeting in simple terms?
It means every dollar of your take-home pay gets assigned a job — a bill, a spending category, or savings — before the month starts, until nothing is left unassigned. It doesn't mean spending everything; savings is one of the categories that gets an assigned amount, not whatever happens to be left over.
Is 50/30/20 or zero-based budgeting better?
Neither is universally better. 50/30/20 is faster to set up and works well for a first-time budgeter with steady income. Zero-based gives more detail and control, which suits someone who has tried a looser method and found it too vague to actually change their spending.
How do I build a budget from my take-home pay?
Start with fixed expenses, then essential variable expenses like groceries and gas, then assign savings and debt payoff, and budget discretionary spending last with whatever remains. Our guide on building a first monthly budget walks through each step with a worked example.
How do I track spending without logging every transaction?
A short weekly check-in against your actual bank and card statements catches nearly everything a daily log would, without the ongoing effort that causes most people to abandon daily tracking within a few weeks.
How do I find subscriptions I forgot I was paying for?
Review three months of bank and card statements for recurring charges, check your phone's app store subscription list separately, and search your email for renewal notices. Together these three places catch nearly every forgotten subscription.
How do I budget with irregular or freelance income?
Build your essential budget off your lowest realistic month, not your average, and route any income above that baseline into a buffer account first. This structure absorbs normal month-to-month swings without breaking the plan.
