What is a regular savings plan, and do you need one?

A regular savings plan (RSP) is a simple arrangement: you invest a fixed amount at a fixed interval, usually monthly, and the contribution is collected automatically from your bank account. In Singapore, banks, brokerages, and fund platforms each offer a version, and for many investors it is the default way to put money to work.

Two questions decide whether an RSP earns its place, and which one to run. The first is what it costs. The charge is usually levied on each contribution, so it does not fall as the portfolio grows. The second is what you actually want to hold. 

This article separates the mechanism from the product, sets out the four ways to run an RSP in Singapore and what each costs, treats dollar-cost averaging honestly, and identifies where a plan fits — and where it does not.

A regular savings plan is a habit, not a product

A regular savings plan invests a fixed amount on a fixed schedule, usually monthly, with the contribution collected automatically from your bank account. 

It helps to separate the mechanism from the products available to investors that decide to use it. The first is an automation of investing at fixed intervals, which removes the monthly decision of whether and when to invest. The second is the wrapper: a specific product such as - for example - DBS Invest-Saver, the OCBC Blue Chip Investment Plan, an FSMOne plan, a brokerage RSP, or an advised portfolio, each with its own menu and price. You can use the mechanism without committing to any one provider’s wrapper.

The mechanism is not to be confused with a regular saver account at a bank, which is a deposit that pays interest but does not invest, or with an insurance savings plan, an endowment policy with a fixed term and surrender conditions. An RSP pays money in as a way to accumulate assets. 

The four ways to run one in Singapore

Four types of route dominate in Singapore: bank plans, brokerage plans, fund platforms, and advised portfolios. They differ on three things — the menu, the charging basis, and whether you can fund the plan with Central Provident Fund (CPF) or Supplementary Retirement Scheme (SRS) money. 

The distinction to notice is the charging basis. Bank and brokerage plans can charge on each contribution, while an advised portfolio charges an annual fee on assets. Why that difference matters more than the rate itself is the subject of the next section.

Why a sales charge and an annual fee are not the same cost

The most common mistake in comparing plans is to read two percentages as though they measure the same thing. They do not.

A sales charge is levied on each contribution. At an illustrative 1%, S$500 invested every month costs S$5 that month, whether the portfolio is worth S$5,000 or S$500,000. The charge does not shrink as the balance grows, because it is taken from the money going in, not the money already invested. As a share of everything you have contributed, it stays at 1% for the life of the plan.

An annual fee on assets works the other way. It is small when the pot is small and larger as the pot grows. The two structures therefore cross: an asset-based fee costs less early and more later. The table below shows both on the same S$500 monthly contribution, at illustrative rates.

On these assumptions the structures cross at about three years. Before that, the annual fee costs less in dollars; after it, the per-contribution charge does, and the gap widens with time. The ranking is not fixed, though — it moves with your contribution size, your holding period, and the rate each provider actually charges.

One figure is absent from both columns: the underlying fund’s expense ratio, which every route pays on top. A platform fee of 0.60% on funds charging 0.50% is a different proposition from the same fee on funds charging 0.10%. Comparing a sales charge against an annual fee without the fund’s expense ratio is the error most comparison tables make, and it tends to flatter whichever figure is being promoted.

What dollar-cost averaging does, and what it does not

Investing a fixed sum each month is a form of dollar-cost averaging: you buy more units when prices are low and fewer when they are high. It is worth being precise about what this achieves.

For someone who is paid monthly, dollar-cost averaging is not a strategy chosen over an alternative. It is simply how money that arrives monthly gets invested. Its benefit is behavioural: it removes the recurring decision of whether now is a good time to invest, a decision investors tend to get wrong. 

What it does not do is raise expected returns. Where an investor already holds a large sum, the evidence favours investing it at once rather than spreading it out. Finlay and Zorn, in a paper written for Vanguard, found that immediate investment outperformed phasing the same amount in about two-thirds of the time, using global market data from 1976 to 2022. Phasing a lump sum in defers exposure and can feel easier to commit to; on average, it has not improved the result. 

What you can actually buy through each route

Price is only half the decision; the other half is what each route lets you hold.

The bank plans are typically built around Singapore-listed securities. DBS Invest-Saver offers a short list of SGX exchange-traded funds (ETFs) and unit trusts; the OCBC Blue Chip Investment Plan covers SGX blue-chip shares and a set of local ETFs; the POEMS Share Builders Plan adds SGX shares, ETFs, and REITs. For an investor who wants a specific local holding these routes are direct and inexpensive.

The ceiling appears when the goal is a globally diversified core. A portfolio built mainly from Singapore-listed instruments carries a pronounced home-market bias, despite Singapore’s SGX being only a small share of global equity markets. Broadening out means either a platform with a wide fund range, such as FSMOne, or an advised portfolio that allocates across global funds. 

The implication is that a reader who wants exactly one named local ETF, funded with S$100 a month, is better served by a bank plan than by an advised portfolio with a higher minimum. A reader who wants a diversified, multi-asset portfolio built and maintained for them is not.

When a regular savings plan is the right answer — and when it is not

Based on their investment objective or risk appetite, An RSP may suit an investor with monthly inflows - say, a paycheck - who is starting from a small balance, or who feels like removing discipline from the equation by automating it. For all three, the mechanism is effective in converting the intention to invest into a standing instruction.

It is a weaker answer for an investor who already holds a large cash balance. Feeding that balance into the market in monthly slices is a decision to phase in — and, as the previous section noted, phasing in has on average trailed investing the sum at once. Someone with savings they are ready to deploy is making a timing choice - deferring an allocation, and therefore potentially foregoing compounding. 

Investment implications

For an investor who has decided to invest monthly into a diversified portfolio, the practical options narrow quickly.

An advised recurring plan — a General Investing or Flagship portfolio on Endowus — automates a fixed monthly contribution into a globally diversified allocation, rebalanced over time and priced on assets rather than on each contribution. An investor who prefers to choose their own funds can use Fund Smart to build a recurring plan from a specific fund list. In both cases Endowus rebates 100% of the trailer fees it receives from fund managers, which lowers the effective cost of the underlying funds — the figure the earlier section flagged as the one most comparisons omit.

The clearest structural difference from the bank plans is funding. Typically, banks do not accept both CPF and SRS contributions when it comes to RSP. Endowus supports recurring contributions from cash, CPF under the CPF Investment Scheme, and SRS, which lets an investor put idle CPF Ordinary Account or SRS balances to work on the same monthly schedule as cash (subject to CPF floor, which means an RSP would stop if OA drops below S$20,000). For how CPF savings fit a longer retirement plan, our guide to CPF LIFE covers the decumulation side.

None of this removes market risk. An RSP invests, and invested capital can fall as well as rise; these portfolios carry no capital guarantee. In our view, the case for a recurring plan rests on two durable advantages: it removes a decision investors tend to get wrong, and it puts every dollar — cash, CPF, or SRS — to work on a schedule you set in advance, without any need for additional actions. 

Frequently asked questions

What is an RSP?

RSP in the context of financial services, savings and investing, stands for regular savings plan: an arrangement to invest a fixed amount at a fixed interval, usually monthly, collected automatically. In investing, an RSP is a way to accumulate assets gradually rather than in a single purchase.

What is the best RSP in Singapore?

There is no single best plan, because the right choice depends on three things: how much you contribute, what you want to hold, and how long you will hold it. An advised recurring plan — a General Investing or Flagship portfolio on Endowus — automates a fixed monthly contribution into a globally diversified allocation, rebalanced over time and priced on assets rather than on each contribution.

Is a regular savings plan worth it?

For an investor who intends to invest monthly, the mechanism automates the contribution and removes the timing decision. Whether a specific plan is worth it depends on its charging basis and menu relative to your needs. The mechanism and the product are separate questions, and warrant two separate decisions. 

What if I invest S$1,000 a month for five years?

Over five years, S$1,000 a month adds up to S$60,000 in contributions. On an assumed gross return of 5% a year, compounded monthly - used here only as an illustration, not a projection - the balance would be in the region of S$68,000, of which about S$8,000 reflects investment growth. Actual returns vary and may be negative; past performance is not necessarily a guide to future performance or returns.

Can I use CPF or SRS for a regular savings plan?

Sometimes, depending on the provider. Several bank RSP promotions are cash-only, and eligibility differs by plan — the OCBC Blue Chip Investment Plan accepts SRS but not CPF, for instance. Endowus supports recurring contributions from cash, CPF under the CPF Investment Scheme, and SRS, subject to the usual scheme rules. Check funding eligibility before committing to a plan.

Can I stop or change a regular savings plan?

Yes. An RSP is a standing instruction, not a fixed-term contract: you can pause, adjust, or stop contributions, and change the amount or the holdings, without the surrender conditions that apply to an insurance endowment plan. That flexibility is part of what distinguishes an RSP from a locked-in savings product.
