What is Coast FI – Coast FI is a financial independence strategy where you save and invest early until your retirement fund can grow on its own. Once you reach this threshold, you can “coast” by reducing savings, switching to lower-stress jobs, or focusing on lifestyle goals, while still being on track for retirement.
How Coast FI Works
- Step 1: Calculate your FIRE number. Multiply expected annual retirement expenses by 25 (based on the 4% withdrawal rule).
- Step 2: Estimate years until retirement. Subtract your current age from your target retirement age.
- Step 3: Determine Coast FI corpus. Use compound interest to see how much you need invested today for it to grow into your FIRE number by retirement.
Example: If you need ₹5 crores at age 60 and have 25 years left, with a 7% real return, you’d need about ₹92 lakhs invested now.
