What is Mr Money Mustache?

The Mr Money Mustache (MMM) method is a financial philosophy that emphasizes financial independence through passive income. The name comes from the idea that once you achieve financial independence, you can "grow a mustache" and stop working.

Living below your means
Investing aggressively in assets that generate passive income
Avoiding lifestyle inflation
Building wealth through compounding returns

Formula

The Mr Money Mustache retirement calculator uses the following formula to determine your monthly savings target:

Monthly Savings Target = (Annual Living Expenses - Annual Income × Savings Rate) / (12 × (1 + Expected Annual Return)^Years to FI)

Where:

Annual Living Expenses = Your desired annual living expenses
Annual Income = Your current annual income
Savings Rate = The percentage of your income you currently save
Expected Annual Return = Your expected annual return on investments
Years to FI = The number of years you expect to take to reach financial independence

This formula helps you determine how much you need to save each month to reach your financial independence goal.

Example Calculation

Let's look at an example to understand how the calculator works. Suppose you have:

Annual income: $60,000
Annual living expenses: $40,000
Current savings rate: 10%
Expected annual return: 7%
Years to financial independence: 10

Using the formula:

Monthly Savings Target = ($40,000 - $60,000 × 0.10) / (12 × (1 + 0.07)^10)

Monthly Savings Target = ($40,000 - $6,000) / (12 × 1.967)

Monthly Savings Target = $34,000 / 23.604

Monthly Savings Target = $1,436.67

This means you would need to save $1,436.67 per month to reach financial independence in 10 years.
