The FIRE Strategy


Find Your Current Savings Rate

Your savings rate is one of the most important factors in reaching FIRE. It determines how much of your income is actually going toward financial independence versus being spent on day-to-day expenses.


How to Calculate Your Savings Rate

1. Find Your Total Savings

Add up how much money you’re saving each month, including:

  • 401(k) and IRA contributions
  • HSA contributions (if applicable)
  • Brokerage account investments
  • Cash savings
  • Investments

2. Find Your After-Tax Income

This is the amount you take home after taxes, including:

  • Salary
  • Bonuses
  • Rental income
  • Side hustles

3. Use the Savings Rate Formula

Savings Rate = (Total Savings / After-Tax Income) * 100

Example Calculation:

  • Total Monthly Savings: $2,000
  • After-Tax Income: $5,000

(2,000 / 5,000) \* 100 = 40%

The higher your savings rate, the faster you reach FIRE because more of your income is working for you.
