Better Money Habits Affordability Calculator

Understanding your financial affordability helps you make smarter spending and saving decisions. This calculator helps you determine how much you can comfortably spend based on your income, expenses, and savings goals.

What is Financial Affordability?

Financial affordability refers to your ability to meet your financial obligations while maintaining a comfortable lifestyle. It's calculated by comparing your income to your expenses and savings goals. A good affordability ratio typically means you're spending less than you earn and saving enough for future needs.

Key affordability metrics include:

Income-to-expense ratio (should be below 50% for good affordability)
Debt-to-income ratio (should be below 36% for good credit)
Savings rate (typically 10-20% of income)

Click "Calculate" to see your affordability results

The calculator will show you your total expenses, remaining income, and affordability percentage.

The Affordability Formula

The affordability percentage is calculated using this simple formula:

Affordability Percentage = (Remaining Income / Total Income) × 100

Where:

Remaining Income = Total Income - Total Expenses - Savings Goal
Total Expenses = Fixed Expenses + Variable Expenses

A higher affordability percentage means you have more money left after expenses and savings, indicating better financial health.

Worked Example

Let's say you have:

Monthly income: $4,000
Fixed expenses: $1,200 (rent, utilities, etc.)
Variable expenses: $800 (groceries, entertainment, etc.)
Savings goal: $500

Calculations:

Total expenses = $1,200 + $800 = $2,000
Remaining income = $4,000 - $2,000 - $500 = $1,500
Affordability percentage = ($1,500 / $4,000) × 100 = 37.5%

This means you have $1,500 left after all expenses and savings, which is 37.5% of your income.

Interpreting Results
