F.I.R.E. Calculator: When Can You Quit Your Job? (2026)

Most people work 40 hours a week for 40 years to pay for a life they are too tired to enjoy. The F.I.R.E. (Financial Independence, Retire Early) movement is the engineering solution to this problem.

It is not magic; it is math. By saving aggressively and investing in broad market index funds, you can reach “Escape Velocity”—the point where your investments pay for your life forever.

At ShockTrail, we view wealth not as Ferraris, but as Freedom units.

The Escape Velocity Calculator

Input your numbers below. We use the “Rule of 25” to determine your Freedom Number.

Annual Spending ($)

Current Portfolio ($)

Monthly Savings ($)

Invest Return (%)

Time to Financial Freedom -- Years

Target Portfolio (The Number): $0

>> FAQ: WEALTH_BUILDING

The "Trinity Study" suggests you can withdraw 4% of your portfolio annually without running out of money for 30 years. This means you need 25x your annual expenses invested to retire.

We recommend using a "Real Return" rate. The S&P 500 historically returns 10%, and inflation is 3%. So, enter 7% in the "Invest Return" box to see purchasing power adjusted results.

Lean FIRE is retiring on minimal expenses (e.g., $25k/year), often by living in a Van or moving to a cheaper country. It allows you to quit your job much faster.

The Mathematics of Freedom

The calculation relies on the 4% Rule, derived from the famous Trinity Study. This study proved that a portfolio of 50% Stocks and 50% Bonds has a 95% success rate of lasting 30 years if you withdraw 4% annually.

How to Speed Up the Clock

You have two levers to pull:

Earn More (Force): Increase income through side hustles or high-yield skills.
Spend Less (Trail): This is more powerful. Every $100 you cut from your monthly expenses lowers your Freedom Number by $30,000.

For example, living in a Van with solar power (calculate your solar needs here) eliminates rent and electricity bills, potentially cutting your required portfolio in half.

Investing from the Financial Capital

While the goal is freedom, understanding the mechanics of Wall Street is crucial. For news on traditional markets and wealth management in the Big Apple, keep an eye on AZNewYork.com.
