Budget0 puts you in complete control of your money with zero-based budgeting β a proven method where every dollar of income is assigned a purpose, so nothing slips through the cracks. ZERO-BASED BUDGETING Start each budget by entering your income, then allocate every dollar to expenses until you reach zero. This ensures you always know exactly where your money is going and helps you save more intentionally. GOALS Saving up for the next family vacation, or paying off a credit card? Create a goal and set money aside for it in any budget. Budget0 shows how far you've come and, if you keep budgeting at your rhythm, roughly how many budgets are still needed and around when you could get there. Reached it? Plan the vacation itself as a new budget from what you saved. SMART CATEGORIZATION Choose from 31 built-in categories for income and expenses, or create your own. Budget0 features AI-powered auto-categorization that learns from your habits, so adding items gets faster over time.
