Financial Freedom Runway — What Is It and How to Calculate Your Path to FIRE?

What Is Financial Freedom Runway?

Financial Freedom Runway is a key indicator showing how many months you can survive without additional income, relying solely on your current financial assets.

Basic Formula:

Runway = Total Assets ÷ Monthly Expenses

Example:

• Assets: 300,000 PLN
• Monthly Expenses: 4,000 PLN
• Runway: 300,000 ÷ 4,000 = 75 months (6.25 years)

Origin of the Runway Concept

From the Startup World

The term "runway" comes from the startup industry, where it means how many months a company can operate before running out of funds in the account.

Application in Personal Finance

In the context of FIRE (Financial Independence, Retire Early), Runway is a progress meter toward financial independence.

Different Types of Runway

1. Basic Runway

Formula: Cash + savings ÷ Monthly expenses

Example:

• Cash: 50,000 PLN
• Monthly expenses: 5,000 PLN
• Basic Runway: 10 months

Application: Emergency fund, short-term security

2. Investment Runway

Formula: (Cash + Investments) ÷ Monthly expenses

Example:

• Cash: 50,000 PLN
• Investments: 400,000 PLN
• Monthly expenses: 5,000 PLN
• Investment Runway: (50,000 + 400,000) ÷ 5,000 = 90 months

3. FIRE Runway (with 4% rule)

Formula: (Investments × 4%) ÷ 12 ÷ Monthly expenses

Example:

• Investments: 1,500,000 PLN
• 4% annually: 60,000 PLN
• Monthly: 5,000 PLN
• FIRE Runway: Infinite (FIRE achieved)
