Financial Independence
What does financial independence actually mean?
Not retiring early. Not being rich. FI is the point where your invested assets generate enough income to cover your living expenses indefinitely, without you needing to trade time for money.
The 4% rule
A widely studied guideline from the Trinity Study: if you withdraw 4% of your portfolio each year, a diversified portfolio of equities and bonds has historically lasted 30+ years. This means you need roughly 25x your annual expenses invested to reach FI.
Example
Annual expenses of S$48,000 means you need S$1.2M invested to reach FI.
FI in Singapore has a CPF layer
Unlike pure FIRE frameworks from the US, Singaporeans build up CPF LIFE, which provides a government-backed annuity from age 65. This baseline income reduces how much your investment portfolio needs to generate. Our calculator applies a 15% discount to account for this, meaning you need slightly less in private investments than the raw 25x rule suggests.
FI is not binary
Most people hit partial FI first: enough passive income to cover essentials, while continuing to work on things they choose. This is sometimes called coast FI or barista FI. The goal is options, not necessarily an abrupt stop.
What the calculator measures
The FI calculator projects how your current savings and monthly contributions compound over time, and identifies the earliest age your portfolio can sustain your lifestyle. It does not account for investment volatility, tax changes, or unexpected expenses. Think of it as a directional tool, not a precise forecast.
