- Enter the annual expenses you want to live on, not today's if you plan to change them.
- Enter what you already have invested and what you invest each month.
- Leave 4% as the withdrawal rate or drop to 3.5% for a margin of safety.
- Try different returns: the gap between 4% and 6% is measured in years.
The 4% rule
It comes from the Trinity study: a diversified portfolio has historically sustained 4% annual withdrawals for 30 years. Your number is your annual expenses times 25.
Taxes in Spain
Withdrawals are taxed as capital gains, between 19% and 30% depending on the amount. If you want 24,000 € net, your gross spending is higher. Raise it in the calculator.
What moves the needle
Monthly savings matter more than return at the start. Return matters more at the end. Both matter less than cutting annual expenses, which lowers the target and raises savings at once.
This is a projection at a constant return. Markets do not behave that way and the sequence of returns matters.
Frequently asked questions
What is the FIRE number?
The capital needed to live off the portfolio. At a 4% withdrawal rate it is 25 times your annual expenses.
Is the expected return real or nominal?
Use the real one (net of inflation) if your expenses are in today's euros. 5% real is optimistic; 3-4% is prudent.
Does the state pension count?
No. If you expect to receive one, subtract it from your annual expenses from retirement age onwards.
What if the result is 100 years?
It means that at this savings rate and return you do not get there. Raise savings, lower expenses, or both.
What is Coast FIRE?
Having enough invested already that, with no further contributions, it reaches the number by retirement age. Try with monthly savings at zero.
