Zero-based budgeting means assigning every dollar of income to a category — expenses, savings, or discretionary spending — until the balance reaches zero. The goal is not to spend everything but to make an intentional plan for every dollar rather than letting untracked money drift into impulse spending. For couples it works particularly well because it forces a monthly conversation about priorities: do we put the extra $300 toward the holiday fund or into the home maintenance buffer? It also makes it clear when spending in one category will come at the cost of another, which reduces financial surprises. Starting with the SpendBeaver budget calculator helps you see your zero-based numbers quickly.
