Budget Planner
Plan your monthly budget by category. Track where every dollar goes and find savings opportunities.
A detailed budget planner is the difference between hoping your finances work out and knowing they will. By breaking spending into specific categories, you can identify exactly where your money goes and find realistic opportunities to save. This planner shows each category as a percentage of income with visual bars, making it easy to spot imbalances and redirect dollars toward your financial goals.
Monthly: $5,000 income, $4,080 expenses. 920 surplus. Consider increasing savings or investments with the surplus.

How to use this calculator
Monthly after-tax income — Your take-home pay after all deductions. Include side income if consistent.
Category amounts — Enter your actual spending in each category. Be honest — underestimate and you'll have a budget that doesn't work.
Visual bars — Each category shows as a percentage of income. Categories over 10% deserve scrutiny. Housing over 30% is a red flag.

Formula & Methodology

Assumptions & limitations
- Uses after-tax (net) income for all calculations.
- Categories are customizable. Adjust amounts to match your actual spending.
- Doesn't account for irregular expenses. Budget 5–10% of income for unexpected costs.
- Annual expenses (insurance, subscriptions) should be divided by 12 and included monthly.
Frequently asked questions
How detailed should my budget be?
Start with 8–12 categories. Too few and you lose visibility; too many and you'll stop tracking. You can always split categories later.
What if my expenses exceed income?
Prioritize needs first (housing, food, insurance), then cut wants. If the gap is structural, look at increasing income or reducing fixed costs like housing.
How do I handle irregular income?
Budget based on your minimum expected monthly income. Any extra goes to savings or debt payoff. This prevents overspending during lean months.
Should I budget for fun?
Absolutely. A budget without fun is a diet without cheat days — it won't last. Allocate 5–10% for entertainment and hobbies. The key is intentionality, not deprivation.
