Complete CPF Guide for Singapore 2026 — Contribution, Allocation, Interest, LIFE

The Central Provident Fund manages over a trillion dollars in member savings across more than four million accounts. Founded in 1955 as a simple retirement scheme, it has evolved into the most comprehensive mandatory savings system in Asia — covering retirement, housing, healthcare, education, and family protection. Understanding how CPF works in 2026 — after the Special Account closure, the final OW ceiling increase, and the latest payout reforms — is essential financial literacy for every working Singaporean and Permanent Resident.

How CPF Works: The Four-Account System

Every Singaporean and PR who earns wages has CPF contributions split across four accounts, each with its own purpose, interest rate, and withdrawal rules:

Ordinary Account (OA) — Used for housing, education, investments, and approved insurance. Earns the OA floor rate of 2.5 percent. This is the most "liquid" CPF account in practical terms because of how broadly it can be used.

Special Account (SA) — Reserved for retirement savings, earning the long-term rate (around 4.0–4.14 percent). From 2025 the SA closed for those aged 55 and above; balances transferred to the Retirement Account. Members below 55 retain their SA and continue to receive the long-term rate on it.

MediSave Account (MA) — For approved medical expenses, MediShield Life and CareShield Life premiums, and certain outpatient treatments. Earns the long-term rate. Capped at the Basic Healthcare Sum, which was $75,500 in 2025 and is adjusted annually.

Retirement Account (RA) — Created on your 55th birthday using savings from your OA and SA. The RA is the source of your CPF LIFE annuity payouts from age 65 (or later if you defer). It earns the long-term rate plus the extra-1-percent and extra-extra-1-percent tiers explained below.

The four-account split is automatic. Every CPF contribution flows into the accounts according to your age band's allocation ratio — you do not choose.

Contribution Rates by Age Band — 2026

The total CPF contribution rate stays at 37 percent of wages for employees aged 55 and below, but progressively reduces at older age bands. The 2026 rates (effective 1 January 2026) are:

Age band	Employee	Employer	Total
55 and below	20.0%	17.0%	37.0%
Above 55 to 60	18.0%	16.0%	34.0%
Above 60 to 65	12.5%	12.5%	25.0%
Above 65 to 70	7.5%	9.0%	16.5%
Above 70	5.0%	7.5%	12.5%

Rates apply to wages up to the Ordinary Wage ceiling of $8,000 per month (final step, from 1 January 2026). Wages above the ceiling do not attract OW contributions.

The Annual Wage Ceiling is $102,000 for 2026. This caps your total OW + AW (bonus) contributions for the year — bonuses are only subject to CPF until the year's combined cap of $102,000 is hit. Use the CPF Contribution Calculator to model your monthly contribution under your specific age band.

A subtle rounding detail: total CPF is rounded to the nearest dollar (round down if cents are below 50); the employee share is then rounded down to the nearest dollar; the employer share equals total minus employee. This is why your payslip's employee-CPF figure is sometimes a dollar less than a naive percentage calculation would suggest.

How CPF Allocates Across Your Accounts

The allocation ratio determines how each 37 percent (or lower) total contribution splits across OA, SA/RA, and MA. The split tilts more toward MediSave as you age — because healthcare needs grow — and toward the Retirement Account from age 55 onwards.

Approximate 2026 allocation ratios (of total contribution):

Age band	OA	SA/RA	MA
35 and below	62.17%	16.21% (SA)	21.62%
Above 35 to 45	56.77%	18.91% (SA)	24.32%
Above 45 to 50	51.36%	21.62% (SA)	27.02%
Above 50 to 55	40.55%	31.08% (SA)	28.37%
Above 55 to 60	35.30%	33.82% (RA)	30.88%
Above 60 to 65	14.00%	44.00% (RA)	42.00%
Above 65 to 70	6.07%	30.30% (RA)	63.63%
Above 70	8.00%	8.00% (RA)	84.00%

A 32-year-old earning $5,000 a month sees roughly $1,150 a month go to OA, $300 to SA, and $400 to MA after applying these ratios. The CPF Allocation Calculator does the full breakdown for any salary and age.

Interest Rates: 2.5% / 4% / Extra 1% / Extra-Extra 1%

CPF interest is one of the best risk-free returns available to Singapore residents. It is paid monthly, computed on the lowest balance of the month, and credited at the end of the year.

Standard rates (2026):

• OA — floor rate of 2.5 percent per annum
• SA / MA / RA — long-term rate, currently around 4.0 to 4.14 percent (reviewed quarterly by CPF Board)

Extra interest tiers:

• Members under 55 — extra 1 percent on the first $60,000 of combined balances (with OA capped at $20,000 of that $60,000). This effectively turns the first $20,000 of OA into a 3.5 percent return.
• Members 55 and above — additional 1 percent on the first $30,000 of combined balances, on top of the standard extra 1 percent. So the first $30,000 in the RA can earn up to 6 percent (long-term rate + 1 percent + 1 percent).

Compounding at these rates over a 40-year career is one reason mandatory savings work as well as they do in Singapore. The CPF Interest Calculator shows what the extra-interest tiers add up to over time.

CPF at Major Life Stages

Age 21 — first job. Your contribution rates jump to the full 37 percent. Most of it (62 percent of the contribution) goes to your OA, where it can be used for HDB, further education, or invested through CPFIS.

Age 35 — peak savings years. The OA share starts dropping and SA share starts rising. You hit the largest gap between contribution and consumption — this is the cohort that benefits most from voluntary CPF top-ups for retirement and tax relief.

Age 55 — Retirement Account is created. Savings from OA and SA flow into the new RA up to the Full Retirement Sum (or Basic Retirement Sum if you've pledged property). Any excess stays in OA and SA (under 55 cohort retained their SA; from 55 onwards SA is closed). You can withdraw from OA above the FRS in cash. Use the CPF Payout 55 Calculator to plan this milestone.

Age 65 — CPF LIFE payouts begin. Default payout start age is 65, but you can defer up to 70 for higher monthly payouts. The CPF Payout 65 Calculator models payout amounts under each scenario.

CPF LIFE: Your Retirement Payout for Life

CPF LIFE is a mandatory annuity scheme. From age 65 (or later if you defer), the savings in your RA are used to fund monthly payouts that continue for as long as you live. The longevity protection is what distinguishes CPF LIFE from a finite drawdown plan.

Three plans:

• Standard — fixed monthly payouts, default option. Predictable income, moderate bequest.
• Basic — higher monthly payout in early years, smaller bequest. (Less common now.)
• Escalating — starts about 20 percent lower than Standard, increases 2 percent every year. Hedges against inflation. Suits members expecting to live into their late 80s and 90s.

Payout amounts depend on your RA balance at 65 (or the age you start), your plan, and CPF Board's actuarial assumptions. As a rough benchmark, a member with Full Retirement Sum in RA at 65 can expect roughly $1,600–$1,700 a month under the Standard Plan. Higher RA balances (up to the Enhanced Retirement Sum) produce proportionally higher payouts.

The CPF LIFE Payout Calculator models payouts across plans and starting ages.

Voluntary Contributions and Tax Relief

Two main channels let you put more into CPF for tax-deductible savings:

Retirement Sum Topping-Up (RSTU) — cash top-ups to SA (under 55) or RA (55 and above). You can top up your own account for up to $8,000 in personal income tax relief, plus another $8,000 for top-ups to your parents, spouse, grandparents, or siblings. Total RSTU relief cap: $16,000 per year.

MediSave voluntary contributions — cash top-ups to MA, subject to the Basic Healthcare Sum ($75,500 in 2025) and the annual CPF contribution cap of $37,740 minus mandatory contributions. Eligible for tax relief in the same year. Useful when you have unused capacity and want a guaranteed 4-percent return.

Voluntary CPF for self-employed — self-employed Singaporeans must contribute to MediSave annually; voluntary contributions to all three accounts (subject to the $37,740 cap) are tax-deductible.

The CPF Top-Up Calculator shows the tax saved at your marginal rate for any top-up amount. At the 11.5 percent bracket (taxable income $80,000–$120,000), a maxed-out $16,000 RSTU saves you $1,840 in tax — plus the long-term 4-percent return on the topped-up amount.

What the 2025 SA Closure Changed

The biggest CPF reform in years took effect 19 January 2025: the Special Account was closed for members aged 55 and above.

What changed:

• SA balances at age 55 (or on the closure date for existing 55+ members) transferred to the RA up to the Full Retirement Sum.
• Any SA balance exceeding the FRS flowed to the OA (where it can be withdrawn in cash or kept earning 2.5 percent).
• Future contributions from age 55 onwards that would have gone to SA now go straight to the RA up to the Enhanced Retirement Sum.
• Members under 55 still have a normal SA with the long-term rate — nothing changed for them yet.

Why CPF Board did it. The SA earned the long-term rate but was withdrawable at 55 (above the FRS). Some members withdrew large sums of high-yielding SA money at 55, dropping out of the high-return tier. The closure aligns the system so that long-term-rate savings stay long-term — earmarked for retirement income through CPF LIFE.

Practical effect. If you turn 55 from 2025 onwards and your SA was above the FRS, the excess no longer earns the 4-percent rate — it now earns the OA's 2.5 percent (or you withdraw it). The strategic move for 55+ members with surplus is to evaluate the CPF 55 Withdrawal Planner carefully — there is no longer a "shielding" trick using SA investments.

Bottom Line

CPF in 2026 is a more streamlined system than it was even three years ago — the OW ceiling reached its final $8,000 step, the SA closure cleaned up the age-55 transition, and CPF LIFE's three plans cover most retirement-income preferences. The fundamentals to internalise: 37 percent total contribution up to age 55, allocation shifts toward MediSave and RA as you age, 2.5 percent OA / ~4 percent on the rest, and an annuity from 65 that you cannot outlive.
