🔎 What Is the Monthly Budget Index (MBI)?
The Monthly Budget Index (MBI) is a financial metric that evaluates your overall financial well-being based on your monthly income, expenses, savings, and investments.
It is calculated using the formula:
iniCopyEditMBI = ((Net Income + Savings + Investments) / Total Income) × 100
Where:
- Net Income = Total Income − Total Expenses
- MBI (%) reflects how much of your income is effectively contributing to your financial growth
A higher MBI suggests better financial control and more potential for long-term stability.

Let’s walk through a practical example.
User Inputs:
- Total Monthly Income: $6,000
- Total Monthly Expenses: $3,600
- Monthly Savings: $600
- Monthly Investments: $400
Step-by-Step Calculation:
- Net Income: $6,000 − $3,600 = $2,400
- Total Savings & Investments: $600 + $400 = $1,000
- MBI: (($2,400 + $1,000) ÷ $6,000) × 100 = 57.00%
Expense Ratio: ($3,600 ÷ $6,000) × 100 = 60.00%
Savings Rate: ($1,000 ÷ $6,000) × 100 = 16.67%
