What is Coast FIRE? A Beginner’s Guide to Financial Independence

Coast FIRE is one of the most exciting and realistic paths within the Financial Independence, Retire Early (FIRE) movement. Instead of pushing for complete financial independence as quickly as possible, Coast FIRE focuses on building a strong foundation early in life and then allowing your investments to “coast” toward retirement. This approach reduces pressure, improves lifestyle balance, and gives you freedom much sooner than traditional retirement plans.

🔎 Understanding Coast FIRE

At its core, Coast FIRE is simple: if you invest enough money early on, compound interest does the heavy lifting. Once you’ve saved your Coast FIRE number—the amount that, if left untouched, will grow into your full retirement fund—you no longer need to contribute aggressively. Your financial independence is secured in the background while you focus on living in the present.

Think of Coast FIRE as planting a financial tree early in life. Once the roots are deep enough, it grows on its own without extra effort.

⚖️ Coast FIRE vs. Other FIRE Paths

The FIRE movement includes several variations. Here’s how Coast FIRE compares:

• Lean FIRE: Living frugally with a smaller nest egg. Requires constant cost-cutting.
• Fat FIRE: Aiming for luxury retirement with a large portfolio. Requires very high savings rates.
• Coast FIRE: Strikes a middle ground. You save early, let compounding take over, and enjoy more freedom in your working years.

📈 How Does Coast FIRE Work in Practice?

Step 1: Save Aggressively Early

During your 20s or 30s, contribute heavily to investments—ideally 30% to 50% of your income. The earlier you start, the less total you need to save.

Step 2: Reach Your Coast FIRE Number

This is the point where your portfolio can grow to your full retirement target by age 60–65 without additional contributions.

Step 3: Coast!

Once you’ve hit the Coast FIRE milestone, you only need to cover current living expenses. You can take lower-paying but fulfilling jobs, work part-time, or even take career breaks without jeopardizing your retirement.

🧮 How to Calculate Your Coast FIRE Number

Your Coast FIRE number depends on three main factors:

1. Your desired annual retirement expenses.
2. The number of years until retirement.
3. Expected annual investment growth rate (typically 5–7%).
