Formula & How It Works
Total Income
Total Income = Salary + Second Income + Side Hustle + Other IncomeSums every income field you enter to get your total available monthly money.
Total Expenses
Total Expenses = Sum of all category fields (Housing + Utilities + Living + Lifestyle + Savings & Debt)Adds up every expense field across all five categories.
Remaining Balance
Remaining = Total Income − Total ExpensesA positive number means you are living within your means; a negative number means you are spending more than you earn.
Category Percentage of Income
Category % = (Category Total ÷ Total Income) × 100Shows what share of your income each spending category consumes, useful for spotting categories that are disproportionately large.
Practical Examples & Common Use Cases
Example 1: Dual-income household
Salary $4,200 + second income $2,100 = $6,300 total income. Housing $1,800, Utilities $350, Living $900, Lifestyle $500, Savings & Debt $1,200 = $4,750 total expenses. Remaining: $1,550/month, or about 25% of income left over.
Example 2: Tight budget, over spending
Total income $3,500. Expenses total $3,850 (Housing $1,400, Utilities $300, Living $700, Lifestyle $650, Savings & Debt $800). Remaining is -$350 — the household is $350/month over budget and needs to trim Lifestyle or Living costs.
Example 3: Applying the 50/30/20 rule
On $5,000 income, the 50/30/20 guideline suggests roughly $2,500 for needs (Housing + Utilities + Living), $1,500 for wants (Lifestyle), and $1,000 for savings and debt repayment.
Frequently Asked Questions
The 50/30/20 rule suggests allocating 50% of after-tax income to needs (housing, food, utilities), 30% to wants (entertainment, dining out, hobbies), and 20% to savings and debt repayment. This calculator helps you see how your actual spending compares to this guideline.
Use your net (after-tax) income — the amount that actually reaches your bank account. This gives you a realistic picture of the money available for expenses and savings.
The calculator will show a negative "Over Budget" amount in red. Review each category to identify areas where you can reduce spending, starting with lifestyle and discretionary categories.
