What is FIRE?
FIRE stands for Financial Independence, Retire Early. It's a financial movement aiming to achieve financial freedom so you can stop working (or choose work without money pressure) much earlier than the traditional retirement age of 55-60.
With passive income from investments sufficient to cover living expenses, you're free to choose how to spend your time — whether that's continuing a career you love, starting a passion project business, or truly retiring.

What is my FIRE Number?
FIRE Number is the amount of money needed to achieve financial independence. The basic formula:
FIRE Number = Annual Expenses ÷ Safe Withdrawal Rate
With a 4% SWR (Trinity Study standard), if your expenses are Rp 7 million/month (Rp 84 million/year), then:
FIRE Number = Rp 84 million ÷ 0.04 = Rp 2.1 billion
Use this calculator to determine your specific FIRE Number with various scenarios.

Does the 4% rule apply in Indonesia?
The Trinity Study that underpins the 4% rule was conducted in the US market with average inflation of 3%. In Indonesia, historical inflation is higher (average 5-6%), so some experts recommend a more conservative Safe Withdrawal Rate of 3.5%.
This calculator provides both options. The more conservative your SWR, the larger your required FIRE Number, but the safer your portfolio from running out prematurely.

What's the difference between Lean FIRE, Regular FIRE, and Fat FIRE?
Lean FIRE (70%) is a frugal lifestyle focused on basics — home cooking, cheap entertainment, public transport. Smaller FIRE Number, achievable faster, but requires high discipline.
Regular FIRE (100%) maintains the same lifestyle as now. Most realistic for the majority of people.
Fat FIRE (130%) is a more comfortable lifestyle with more travel, dining out, and expensive hobbies. Larger FIRE Number, takes longer or requires higher income.
Choose according to your values and priorities — there's no right or wrong answer. You can also use the custom slider to set your own expense percentage.

Do I have to stop working after FIRE?
Not at all. FIRE isn't about not working at all, but about freedom to choose.
After FIRE, you can:
- Continue working but in a field you love without salary pressure
- Work part-time or freelance
- Start a passion project business
- Truly retire and focus on hobbies, family, travel
The key is that money is no longer the main reason for working. That's the definition of financial freedom.

How can BPJS JHT accelerate FIRE?
BPJS JHT is a mandatory savings program with 5.7% of salary contributions (2% employee + 3.7% employer) that can be withdrawn at age 56 or after 10 years of not working.
If you FIRE at age 45-50, JHT can be withdrawn after 10 years (age 55-60). This calculator factors in the JHT lump sum value in the year you achieve FIRE as an additional asset that reduces your required personal savings.
Note: JHT can only be withdrawn once, and doesn't generate monthly passive income like investments. Use it wisely — ideally to strengthen your portfolio, not spend immediately.
