A passive income calculator in Singapore estimates how much investment capital you need to generate a target monthly income from dividends, REIT distributions, bond interest, or ETF returns. The core formula: Required Capital = (Monthly Target × 12) ÷ Annual Yield. As at Q1 2026, investors targeting S$3,000–S$5,000/month typically need S$600,000–S$1,000,000 at a 5–6% blended yield, supplemented by CPF LIFE payouts from age 65.
The Passive Income Formula
Required Capital = (Monthly Passive Income × 12) ÷ Annual Yield. Examples: S$3,000/month at 5% yield = S$720,000; S$5,000/month at 5.5% = S$1,090,909; S$10,000/month at 6% = S$2,000,000. Higher yields reduce capital required but carry more risk. Always stress-test at a lower yield (e.g., 4%) to account for DPU cuts or dividend reductions.
Realistic Yields for Singapore Passive Income Portfolios (2026)
As at Q1 2026: S-REITs yield 5–7% (blue-chip 4.5–6%); Singapore dividend stocks (DBS, OCBC, UOB) yield 4–6%; Singapore Savings Bonds and T-bills yield ~2.8–3.4%; major bank fixed deposits offer 2.8–3.5% for 12-month tenors; Nikko AM STI ETF yields ~3.5–4%. A blended portfolio targeting 5–5.5% yield is realistic for a diversified Singapore investor.
CPF LIFE as a Passive Income Floor
CPF LIFE is effectively a state-guaranteed passive income stream. Members topping up their RA to the Enhanced Retirement Sum (ERS of S$426,000 in 2026) receive approximately S$2,300–S$2,900/month from age 65 under the Standard Plan. A Singapore couple with both spouses at ERS receives S$4,600–S$5,800/month combined — close to covering average household retirement expenses. CPF LIFE dramatically reduces the private portfolio needed.
Building a S$5,000/Month Passive Income Portfolio
A practical allocation: S$600,000 in S-REITs at 6% = S$3,000/month; S$200,000 in dividend stocks at 5% = S$833/month; S$100,000 in SSBs at 3% = S$250/month. Private portfolio: ~S$4,083/month. Add CPF LIFE (RA at ERS): ~S$2,500/month. Combined: ~S$6,583/month gross. CPF LIFE starts at 65 — bridge the 65-70 gap with SRS withdrawals or private portfolio income.
The FIRE Number for Singapore Investors
FIRE uses the 25× rule: multiply annual expenses by 25 for the portfolio needed at a 4% withdrawal rate. For S$72,000/year expenses: FIRE = S$1,800,000. Singapore investors benefit from no capital gains tax and CPF LIFE reducing the private portfolio target. A practical Singapore FIRE number (including CPF LIFE): S$800,000–S$1,200,000 in private investments for a couple. Use TKN’s Passive Income Goal Calculator for personalised scenarios.

Frequently Asked Questions
How much money do I need for S$3,000/month passive income in Singapore?
At 5% yield: S$3,000 × 12 ÷ 0.05 = S$720,000. At 6% (e.g., S-REITs): S$600,000. Factor in inflation — your target needs to grow over time. CPF LIFE from age 65 can cover part of this, reducing your private investment requirement.
What are the best passive income sources in Singapore?
S-REITs (5–7% yield), Singapore dividend stocks like DBS and OCBC (4–6%), Singapore Savings Bonds and T-Bills (2.8–3.4%), CPF LIFE payouts, SRS investments, and fixed deposits are the most common sources for Singapore income investors.
Is dividend income taxed in Singapore?
No. Singapore does not tax dividends from Singapore-listed companies or REIT distributions. Foreign dividends may face withholding tax in the source country. There is no capital gains tax in Singapore — making it one of Asia’s most tax-friendly environments for income investing.
Can CPF be used for passive income?
Yes. CPF LIFE provides guaranteed monthly payouts from age 65. CPF OA funds above S$20,000 can be invested via CPFIS in dividend ETFs and REITs. SRS contributions (tax-deductible) can be invested for additional retirement income via Endowus or FSMOne.
What is the FIRE number for a Singapore investor?
Approximately 25× annual expenses. If you spend S$60,000/year, FIRE = S$1,500,000. Singapore investors reduce this by factoring in CPF LIFE payouts (S$2,500–S$5,800/month per couple) and the absence of capital gains tax.
