Question 1

What is the FIRE number and how is it calculated?

Accepted Answer

The FIRE number is the portfolio size you need to retire early and live off investment returns indefinitely. It's calculated as: Annual Expenses ÷ Safe Withdrawal Rate (SWR). At 4% SWR, FIRE Number = Annual Expenses × 25. Example: S$60,000/yr expenses → FIRE number = S$1,500,000. In Singapore, your CPF LIFE payout (from age 65) reduces the portfolio you need, since it covers part of your annual expenses.

Question 2

What is a safe withdrawal rate (SWR) for Singapore?

Accepted Answer

The 4% rule was based on US historical data (1926–1994, Bengen study). For Singapore investors with a global ETF portfolio, 4% is commonly used but 3–3.5% is more conservative given: (1) Singapore equities (STI) have historically underperformed US equities; (2) sequence of returns risk is higher for longer retirements (retiring at 40 vs 65); (3) no US-equivalent Social Security — CPF LIFE partially fills this role. Use 3.5% if retiring before 50, 4% if retiring at 55+.

Question 3

Should I include CPF in my FIRE number?

Accepted Answer

No — CPF OA and SA are illiquid until age 55, and even then only excess above the Full Retirement Sum (FRS, S$213,000 in 2026) can be withdrawn. Count CPF separately. What CPF does contribute is CPF LIFE payouts from age 65 (~S$1,000–2,000/mo depending on your RA balance), which reduces how much your investment portfolio needs to cover. This calculator keeps CPF separate and deducts CPF LIFE income from your required portfolio drawdown.

Question 4

What is Lean FIRE, Regular FIRE, and Fat FIRE in Singapore?

Accepted Answer

Lean FIRE: ~S$2,000–3,000/mo household expenses. Bare essentials, no frills. Requires ~S$600K–900K. Regular FIRE: S$4,000–6,000/mo. Comfortable middle-class Singapore lifestyle. Requires ~S$1.2M–1.8M. Fat FIRE: S$8,000–12,000+/mo. Private property, travel, private school for kids. Requires S$2.4M–3.6M+. Barista FIRE: Retire from full-time work but do part-time or freelance to supplement. Smaller portfolio needed — the income bridges the gap.

Question 5

How does CPF LIFE affect my FIRE calculation?

Accepted Answer

CPF LIFE provides monthly payouts from age 65 for life. At FRS (S$213,000 in RA), payouts are approximately S$1,300–1,600/mo under the Standard Plan. If you retire at 50 and spend S$60,000/yr, you need your portfolio to fund all S$60,000/yr for 15 years (50–65), then only S$43,200/yr from 65 (if CPF LIFE pays S$1,400/mo = S$16,800/yr). This effectively reduces your FIRE number. The calculator deducts CPF LIFE income from required annual drawdown.

Question 6

What return rate should I use for a Singapore FIRE calculator?

Accepted Answer

For a globally diversified ETF portfolio (VWRA, IWDA + EIMI): 6–7% nominal, 3.5–4.5% real (after 2.5% inflation). For CPF OA: 2.5% (3.5% on first S$20K). For CPF SA: 4% (5% on first S$40K). For Singapore STI-only: 5–6% nominal (lower than global due to sector concentration). The calculator uses real returns — enter 6% if you want to model purchasing power in today's dollars, or 8.5% nominal if you prefer to see inflated nominal figures.

Type	Annual Expenses	FIRE Number	FIRE Age	Status
Lean FIRE	S$42,000/yr	S$690,000	43	✓ On track
FIRE	S$60,000/yr	S$1.14M	48	✓ On track
Fat FIRE	S$90,000/yr	S$1.89M	54	✗ Behind

Step	Formula	Example (S$5K/mo expenses)
Annual expenses	Monthly × 12	S$60,000/yr
Less CPF LIFE	− monthly payout × 12	− S$16,800 (S$1,400/mo)
Net annual drawdown	Expenses − CPF LIFE	S$43,200/yr
FIRE number	Net drawdown ÷ SWR	S$43,200 ÷ 4% = S$1,080,000
Years to FIRE	Solve: PV × (1+r)^n + PMT × [(1+r)^n−1]/r ≥ target	Depends on savings rate

Lifestyle	Monthly Expenses	FIRE Number (4% SWR)	With CPF LIFE (S$1,400/mo)
Lean FIRE	S$2,500/mo	S$750,000	S$330,000
Regular FIRE	S$5,000/mo	S$1,500,000	S$1,080,000
Comfortable FIRE	S$8,000/mo	S$2,400,000	S$1,980,000
