⌛ Age Horizon & Net Worth Inputs
💡 What This Means For You
You need ₹1,970,662 more in invested net worth to reach Coast FIRE. Once you hit ₹3,470,662, your investments will compound on auto-pilot until age 60!
What is the Coast FIRE & Early Financial Independence Predictor?
The Coast FIRE & Early Financial Independence Predictor calculates the exact net worth milestone at which you can stop saving for retirement entirely ("coasting") and let compound growth do all the heavy lifting until your target retirement age.
Unlike Traditional FIRE (where you accumulate enough wealth to quit working immediately), Coast FIRE means your existing invested portfolio is already large enough to compound into your full retirement goal (25x annual expenses) by age 60 or 65.
Once you reach your Coast FIRE Target, you only need to earn enough money to cover your current annual living expenses — freeing you up to take lower-stress jobs, start a passion business, work part-time, or take extended sabbaticals.
This calculator factors in your current age, target retirement age, current invested net worth, expected inflation-adjusted return (e.g. 7%-9% real return), and calculates your Coast FIRE Target, Current Surplus/Deficit, and Coast FIRE Age.
How Does the Coast FIRE & Early Financial Independence Predictor Work?
1. Enter Current & Retirement Target Age — Input your age today (e.g. 30) and target retirement age (e.g. 60).
2. Input Current Net Worth Invested — Total invested assets in stocks, mutual funds, EPF, and index funds.
3. Set Desired Retirement Annual Expenses — Living expenses needed per year at retirement (today's value).
4. Choose Expected Investment CAGR (%) & Inflation (%) — Set inflation-adjusted real growth rate.
5. View Coast FIRE Status & Compounded Projection — Review your Coast FIRE target number today vs current net worth surplus/deficit.
Formula & Calculation Method
1. Target Retirement Corpus (4% Rule):
$$\text{Target Corpus} = \text{Annual Retirement Expenses} \times 25$$
2. Real Return Rate:
$$\text{Real CAGR} = \text{Expected Nominal Return %} - \text{Annual Inflation %}$$
3. Coast FIRE Target Today:
$$n = \text{Target Retirement Age} - \text{Current Age}$$
$$\text{Coast FIRE Target} = \frac{\text{Target Corpus}}{(1 + \text{Real CAGR}/100)^n}$$
4. Coast FIRE Status (Surplus / Deficit):
$$\text{Status} = \text{Current Invested Net Worth} - \text{Coast FIRE Target}$$
Example Calculation
Example: Age 30 wanting to retire at Age 60 with $40,000/yr ($1,000,000 Target Corpus)
- Current Invested Net Worth: $150,000
- Years to Compound: 60 - 30 = 30 Years
- Nominal Return: 10% | Inflation: 3% → Real CAGR = 7%
Calculations:
- Required Target Corpus at 60: $40,000 × 25 = $1,000,000
- Coast FIRE Target Needed Today: $1,000,000 ÷ (1.07)^30 = $131,367
- Status: $150,000 - $131,367 = +$18,633 Surplus!
- Result: You have already achieved Coast FIRE! You can stop saving for retirement today.
