Budget Calculator
Create a personalized budget and see where your money goes each month
How to Use This Budget Calculator
- Enter all income sources: salary (after tax), side income, investment income, other
- Input fixed expenses: housing, utilities, internet, car payment, insurance
- Add variable expenses: groceries, dining, entertainment, subscriptions, personal care
- Include debt payments and planned savings/investment amounts
- Click 'Analyze Budget' to see your financial snapshot
- Review the 50/30/20 comparison and savings rate
Example: Monthly income of $5,500 with $1,800 rent, $200 utilities, $400 car payment, $500 groceries, $200 dining, and $550 savings results in a $850 monthly surplus. Savings rate is 10% - below the recommended 20%, but the surplus allows room to increase.
Tip: Enter your actual spending for the past 3 months to get an accurate picture. Most people underestimate variable expenses like dining and entertainment.

Formula
Net Cash Flow = Total Income - Total Expenses Positive cash flow means you spend less than you earn. Negative cash flow means you're either depleting savings or accumulating debt. Your savings rate = (Income Saved / Total Income) × 100%.
Current Standards: 50/30/20 rule: 50% of after-tax income to needs (housing, utilities, groceries, insurance, minimum payments), 30% to wants (dining, entertainment, subscriptions, hobbies), 20% to savings and extra debt payments.
Frequently Asked Questions
What if I can't make the 50/30/20 rule work?
The 50/30/20 rule is a guideline, not a law. In high cost-of-living areas, housing alone might exceed 50%. Adjust ratios to your reality - maybe 60/20/20 makes more sense. The key principle is spending less than you earn and consistently saving something, even if it's less than 20%.
Should I budget based on gross or net income?
Budget based on net (take-home) income - what actually hits your bank account. Gross income is misleading because taxes, insurance, and 401(k) contributions are already gone. Your budget should reflect money you can actually spend or save.
How do I handle irregular expenses?
List all annual expenses (insurance premiums, car registration, subscriptions, gifts, vacations) and divide by 12. Add that monthly amount to your budget as 'irregular expense fund.' When those bills come due, the money is already set aside. This prevents budget blowups from predictable expenses.
What's the best budgeting method?
The best method is one you'll stick with. Options include: zero-based (give every dollar a job), envelope system (physical or digital cash allocation), pay yourself first (automate savings then spend the rest), or values-based (prioritize spending on what matters most). Try different approaches to find your fit.
How often should I review my budget?
Review actual vs planned spending weekly (15 minutes). Do a full budget review monthly (30 minutes). Revise the budget itself quarterly or after major life changes. The goal is awareness, not obsession. Once habits form, you'll need less active tracking.
