<h1>CPF Overview</h1> <p>The Central Provident Fund (CPF) is Singapore's compulsory savings system and the backbone of its social security model. Every working Singapore citizen and permanent resident, and their employer, contributes a fixed percentage of monthly wages — up to 37% combined for workers aged 55 and below — into individual accounts that can only be spent on designated purposes: housing, healthcare, retirement income, and a narrow set of investments and insurance (<a href="https://www.cpf.gov.sg/member/cpf-overview">CPF Board, accessed Aug 2026</a>). The design is philosophically distinct from Western welfare states: instead of pooling taxes to fund universal benefits, CPF makes each household self-fund its own major life expenses from forced savings, with government subsidies and top-ups layered on for lower-income members. Almost every other Singaporean social policy — public housing purchase, hospital bills, retirement payouts — routes through it.</p> <h2>Origins and philosophy</h2> <p>CPF was established in 1955 by the British colonial administration as a simple retirement savings scheme, but it was after self-government and independence that it became the multi-purpose instrument it is today. The pivotal change came in 1968, when members were allowed to use CPF savings to buy <a href="/en/knowledge/article/sgkb.housing.hdb-system-overview">HDB flats</a>, converting a locked retirement fund into the engine of mass home ownership (see <a href="/en/knowledge/article/sgkb.cpf-social-security.cpf-housing-usage">cpf housing usage</a>). MediSave followed in 1984 to fund healthcare, and successive retirement schemes culminating in <a href="/en/knowledge/article/sgkb.cpf-social-security.cpf-life">CPF LIFE</a> addressed longevity (<a href="https://www.cpf.gov.sg/member/infohub/educational-resources/from-paper-to-pixels-how-your-cpf-statements-have-changed-over-the-last-70-years">CPF Board, CPF history</a>). The governing philosophy is individual responsibility with state scaffolding: benefits are broadly proportional to what a member has contributed, which avoids intergenerational transfers and keeps taxes low, but leaves those with fragmented or low-wage careers with thin balances — the standard critique, partly addressed by Workfare, Silver Support, and government top-ups (see <a href="/en/knowledge/article/sgkb.cpf-social-security.workfare-and-support-schemes">workfare and support schemes</a>; <a href="https://www.cpf.gov.sg/member/growing-your-savings/government-support/workfare-income-supplement">CPF Board, Workfare</a>).</p> <h2>The accounts</h2> <p>Contributions are split across accounts, each with its own permitted uses:</p> <ul> <li><strong>Ordinary Account (OA)</strong> — housing, approved investments, insurance, and education loans. This is the account most Singaporeans spend from, primarily on a flat.</li> <li><strong>Special Account (SA)</strong> — long-term retirement savings, earning the higher interest rate.</li> <li><strong>MediSave Account (MA)</strong> — healthcare: hospitalisation, approved outpatient treatments, long-term care, and premiums for MediShield Life and CareShield Life (see <a href="/en/knowledge/article/sgkb.healthcare.healthcare-financing">healthcare financing</a>).</li> <li><strong>Retirement Account (RA)</strong> — created at age 55 by consolidating SA and OA savings; funds CPF LIFE payouts from the payout eligibility age.</li> </ul> <p>Allocation across accounts is computed MediSave-first, then Special/Retirement, with the balance to the Ordinary Account, and the split shifts with age — younger members get proportionally more into OA, older members more into MA and retirement savings (<a href="https://www.cpf.gov.sg/member/cpf-overview">CPF Board, accessed Aug 2026</a>). Current contribution rates by age band and the Ordinary Wage ceiling (S$8,000/month from 1 January 2026) are tracked in <a href="/en/knowledge/dataset/sgkb.data.annual-rates">annual rates</a>.</p> <h2>Interest rates</h2> <p>CPF savings earn government-guaranteed, risk-free interest that is well above bank deposit rates, which is a large part of the system's value. The Ordinary Account pays 2.5% per annum, and the Special, MediSave, and Retirement Accounts pay 4% per annum, both as of Q1 2026; the 4% floor on SMRA monies has been extended repeatedly, most recently through 31 December 2026 (<a href="https://www.cpf.gov.sg/member/infohub/news/news-releases/cpf-interest-rates-from-1-january-to-31-march-2026-and-basic-healthcare-sum-for-2026">CPF Board, accessed Aug 2026</a>). On top of the base rates, members below 55 earn an extra 1% on the first S$60,000 of combined balances, and members 55 and above earn an extra 2% on the first S$30,000 plus an extra 1% on the next S$30,000 — in both cases counting at most S$20,000 from the Ordinary Account (<a href="https://www.cpf.gov.sg/member/infohub/news/news-releases/cpf-interest-rates-from-1-january-to-31-march-2026-and-basic-healthcare-sum-for-2026">CPF Board, accessed Aug 2026</a>). The practical consequence is that money left in CPF compounds at rates no comparable safe asset in Singapore matches, which is why &quot;should I use OA for my flat or leave it to compound?&quot; is a standard household dilemma.</p> <h2>Ceilings and retirement sums</h2> <p>Two sets of thresholds govern how much a member must or may keep in the system. The <strong>Basic Healthcare Sum</strong> caps MediSave balances: it is S$79,000 for members below 65 in 2026, up from S$75,500, and is frozen for life at the level applying when a member turns 65 (<a href="https://www.cpf.gov.sg/member/infohub/news/news-releases/cpf-interest-rates-from-1-january-to-31-march-2026-and-basic-healthcare-sum-for-2026">CPF Board, accessed Aug 2026</a>). The <strong>retirement sums</strong> set how much must be kept in the Retirement Account at 55 before the rest can be withdrawn: for the cohort turning 55 in 2026, the Basic Retirement Sum is S$110,200, the Full Retirement Sum S$220,400 (twice BRS), and the Enhanced Retirement Sum S$440,800 (four times BRS), with each cohort's sums rising roughly 3.5% a year and then fixed for life (<a href="https://www.mom.gov.sg/-/media/mom/documents/budget2022/factsheet-on-basic-retirement-sums-for-cpf-members-reaching-age-55-from-2023-to-2027.pdf">MOM factsheet, accessed Aug 2026</a>). Members who own property and pledge it can set aside only the BRS and withdraw more cash; the sums translate into monthly <a href="/en/knowledge/article/sgkb.cpf-social-security.cpf-life">CPF LIFE</a> payouts for life.</p> <h2>Recent changes and debates</h2> <p>The most significant structural change in years took effect on 19 January 2025, when the Special Accounts of about 1.4 million members aged 55 and above were closed: those balances moved to the Retirement Account up to the Full Retirement Sum, with any excess going to the Ordinary Account, which pays the lower short-term rate but remains withdrawable (<a href="https://www.cpf.gov.sg/member/infohub/news/news-releases/closure-of-special-account-for-cpf-members-aged-55-and-above-and-other-cpf-enhancements">CPF Board, accessed Aug 2026</a>). The stated rationale was to stop members parking short-term, withdrawable money in a long-term account to earn the higher rate; the change was unpopular with savers who lost that arbitrage. Longer-running debates concern whether the system delivers retirement adequacy — heavy OA spending on housing can leave thin retirement balances — whether the rising retirement sums amount to moving goalposts, and whether returns should track the actual investment performance of the reserves managed by GIC (see <a href="/en/knowledge/article/sgkb.economy-finance.gic-and-temasek">gic and temasek</a>). The government's consistent answer is that CPF rates are risk-free guarantees, not fund returns, and that housing wealth is itself retirement wealth.</p>
