"How much life insurance do I need?" is the single most common question Singaporeans ask before buying a policy — and the honest answer is that the number depends less on a rule of thumb than on who depends on your income, what debts you would leave behind, and how long that dependency lasts. This guide walks through the three sizing methods advisers actually use in Singapore, with worked examples.
Method 1 — Income replacement (the 10× rule). The quickest heuristic: multiply your annual income by 10. A Singaporean earning S$120,000 a year would target S$1.2 million in cover. It is fast, but crude — it ignores whether you have dependants, how big your mortgage is, and how much you have already saved. Treat it as a floor for a working parent with young children, not a final answer.
Method 2 — DIME (Debt, Income, Mortgage, Education). Add up: outstanding Debt (car loan, renovation loan, credit lines); Income replacement for the number of years your family needs support (typically until the youngest child is financially independent, often 15–20 years); outstanding Mortgage (HDB or private); and Education costs for each child. As a reference, MOE-subsidised annual tuition for Singapore citizens at the local autonomous universities is roughly S$8,200–9,600 per year for AY2025/26 depending on faculty, i.e. about S$33,000–40,000 in tuition over a 4-year degree, with living costs and miscellaneous fees on top; an overseas 4-year undergraduate typically runs S$250,000–400,000 depending on country. Subtract existing life cover and liquid assets you would leave behind. The remainder is your gap.
Method 3 — Needs-based (the adviser standard). Project the actual cash flows your family would need if you were not there: monthly household expenses × months of support, plus lump sums (mortgage payoff, education, emergency fund of 6–12 months expenses, funeral costs typically S$8,000–15,000 in Singapore), minus resources they would have (CPF balances payable via nomination, existing insurance, savings, spouse's income). Most qualified financial advisers use a variant of this, often built into their financial-needs analysis (FNA) tools.
Worked example — young family, one income. Alex is 35, earns S$8,000/month, has a wife (homemaker) and two children aged 3 and 5. Outstanding HDB loan S$400,000. Existing term cover S$250,000. DIME: Debt S$20,000 + Income (S$6,000/month × 20 years = S$1.44m, discounted lightly for inflation-adjusted investment returns to roughly S$1.1m) + Mortgage S$400,000 + Education S$300,000 (two local degrees + buffer) = S$1.82m. Less existing S$250,000 = gap of roughly S$1.57 million. A 25-year level term plan for that sum assured typically costs a 35-year-old non-smoker between S$110 and S$160 a month in Singapore.
Worked example — dual-income couple, no kids yet. Priya and Ravi both earn S$7,000/month, own a S$600,000 condo with S$450,000 outstanding, no children yet but planning. Each partner's gap under DIME is smaller because the survivor keeps their own income: mortgage payoff (half each, or joint depending on how they structure it) plus 3–5 years of income replacement to give the survivor breathing room, plus a future-children buffer. Realistic target: S$500,000–750,000 each in level term to age 65.
Worked example — business owner. Ken, 45, runs an SME with S$300,000/year in personal drawings, personal guarantees on a S$500,000 business loan, wife and two teenage children. Two separate needs: (1) personal life cover under DIME — probably S$1.5–2 million; (2) key-person or business-continuity cover so his shareholding can be bought out and the business loan settled without forcing his family to run a company they did not sign up for. This is where personal life insurance alone under-answers the question, and where structured buy-sell or key-person policies come in.
Common Singapore-specific mistakes. Forgetting CPF nominations — CPF savings are not covered by your will and pass to nominated beneficiaries; unnominated CPF goes to the Public Trustee and takes months. Assuming your employer's group term cover is enough — it usually caps at 24–36× monthly salary, does not follow you when you change jobs, and drops to zero at retirement. Double-counting your HDB Home Protection Scheme — HPS covers the mortgage on death or TPD but only for HDB flats, and only up to the outstanding loan; it is not general life cover. Ignoring inflation — a S$1m payout today is worth materially less in 20 years; either build in a buffer or use increasing-term riders.
How much cover is "too much"? If premiums exceed roughly 5–8% of gross household income, the plan is usually oversized or the wrong product mix. Term life should be affordable; if it is not, either the sum assured is too high, the term is too long, or whole life has been sold where term would have done the job.
Where StickieMonies fits in. We help Singapore households and business owners run these numbers properly — including CPF nominations, existing group cover, HPS, and any whole-life or ILP policies you already hold — so the target sum assured reflects your actual gap, not a rule of thumb. We are product-agnostic and independent. If you would like a second view on a quote or a fresh sizing from scratch, we are happy to walk through it.
