# Zero-based budget builder — plan every dollar, no upload > Build a zero-based budget: assign every dollar of income to categories until the plan balances. Runs in your browser, no upload. Informational only. Build a zero-based budget by assigning every dollar of income to a category until income minus planned spending equals zero. It runs on your device and is a planning aid, not financial advice. A zero-based budget forces intention: instead of spending and hoping, you give every dollar a job before the month starts. This builder keeps a running total so you can see the plan balance as you assign categories. Base your categories on real spending from the Statement analyzer, look ahead with the Cash-flow forecaster, and catch recurring drains with the Subscription tracker. ## How to 1. **Enter income.** Add your monthly take-home income. 2. **Assign categories.** Give every dollar a job across spending and savings. 3. **Balance to zero.** Adjust until income minus assignments reaches zero. ## FAQ ### What is a zero-based budget? A method where you assign every dollar of income a purpose — spending, saving, or debt — so the plan sums to zero, ensuring no money is unaccounted for. ### Does zero mean I spend everything? No — savings and debt payments are 'jobs' too. Zero means every dollar is intentionally allocated, not that your balance ends at zero. ### Is this financial advice? No. It's a budgeting framework you fill in yourself; the numbers and priorities are entirely your own. ## Related tools - [Import & analyze](https://www.safepaper.app/finance/statement-import) - [Cash-flow forecast](https://www.safepaper.app/finance/cash-flow) - [Subscriptions](https://www.safepaper.app/finance/subscription-tracker) - [Debt payoff](https://www.safepaper.app/finance/debt-payoff) --- Canonical HTML: https://www.safepaper.app/finance/budget-builder Markdown: https://www.safepaper.app/finance/budget-builder.md There is no upload endpoint — your files are processed in this browser tab.
