Enter Your Monthly Gross Income
Enter your total gross (pre-tax) monthly income from employment. If you're salaried, divide your annual salary by 12. If you're self-employed or have variable income, use a conservative 3-month average. The calculator estimates net income based on typical tax rates — this is an approximation, not exact tax calculation.
Enter Monthly Rental Income (Optional)
If you own a rental property, enter your gross monthly rental income here. In the next field, enter monthly rental expenses (mortgage, property tax, insurance, maintenance) to calculate net rental income.
Enter Monthly Living Expenses
This is your total monthly spending on everything: rent/mortgage, groceries, utilities, subscriptions, dining, entertainment, transportation, insurance, and personal care. Be honest — use your actual bank and credit card statements, not what you think you spend.
Enter Monthly Debt Payments
Enter the total minimum monthly payments across all debts: student loans, car loans, credit cards, lines of credit. Do not include your mortgage here if it's already counted in living expenses.
Choose the Forecast Period
Select how many months ahead you want to project (12, 24, 36, or 60 months). The calculator applies typical income growth (3%/year) and expense growth (2.5%/year) to show how your cash flow will evolve.
Read Your Monthly Surplus or Deficit
The banner shows your current monthly surplus (green) or deficit (red). A deficit means you're spending more than you earn — this requires immediate action. A surplus is how much you have available for savings and investments.
Check Your Savings Rate
The savings rate bar shows what percentage of gross income you're saving. The recommended target is 20% or higher. Below 10% is a warning zone. The bar color changes from red → amber → green as you approach the target.
Review the Monthly Forecast Table
The table shows the first 6 months of your projected cash flow. Because income grows slightly faster than expenses (3% vs 2.5%), your surplus should improve month-by-month. If you're currently negative, this table shows when you're projected to break even.
Act on the Insights and Suggestions
The calculator provides personalized insights based on your numbers. If debt payments exceed 30% of income, it flags this and suggests prioritizing payoff. If your savings rate is under 10%, it suggests finding discretionary cuts.
