Budget Calculator Formula

The budget estimator uses straightforward financial calculations to summarize your monthly finances.

Total Monthly Income

$\text{Total Income} = \sum \text{All Income Sources}$

Where:

• Total Income = Combined monthly earnings from every income source.

Total Monthly Expenses

$\text{Total Expenses} = \sum \text{All Expense Categories}$

Where:

• Total Expenses = Combined monthly spending across all categories.

Net Monthly Balance

$\text{Net Balance} = \text{Total Income} - \text{Total Expenses}$

Where:

• Net Balance = Money remaining after all monthly expenses.

A positive balance means you're spending less than you earn, while a negative balance indicates your expenses exceed your income.

Savings Rate

$\text{Savings Rate} = \frac{\text{Monthly Savings}}{\text{Total Income}} \times 100$

Where:

• Monthly Savings = Amount allocated toward savings.

• Total Income = Total monthly earnings.

This percentage shows how much of your income you're saving each month.
