Monthly Investing with SRS in Singapore: How to Set Up a Regular Savings Plan

At the end of December 2025, 21% of Singapore's SRS investment portfolio was still sitting in cash, across 516,376 account holders and S$23.88 billion in cumulative contributions. Plenty of investors remember to top up their SRS account before the tax deadline. Far fewer turn that money into a steady monthly investment habit, which is what an SRS regular savings plan is designed to do.

An SRS regular savings plan is a routine in which you contribute to your Supplementary Retirement Scheme account and invest that money in fixed amounts at regular intervals, usually monthly. The annual caps set the ceiling: S$15,300 a year for Singapore Citizens and Permanent Residents, and S$35,700 for foreigners. Spread evenly over 12 months, those caps work out to S$1,275 and S$2,975 a month. Cash you leave uninvested in the account at DBS earns 0.05% a year.

A monthly SRS plan is really two separate recurring actions. The first moves money from your bank account into SRS, which is a top-up you make yourself through your operator bank's own channels. The second takes cash already in SRS and buys investments with it, which is the part a broker, bank or investment platform can automate. Treating them as one step is the most common reason a monthly plan stalls.

On the investing side, investors here have three main routes: SGX-listed ETF and blue-chip plans run by banks and brokers, managed portfolios that accept SRS money, and ETF platforms that let you set up recurring orders. Each has different minimums, fee structures and investment choices.

This guide explains how the two monthly steps work, the three ways to invest SRS money each month, how dollar-cost averaging plays out with worked numbers, what monthly orders cost against a single lump sum, how year-end timing affects tax relief, and a set-up checklist you can follow this month.

SRS regular savings plans at a glance

Three things shape a monthly SRS plan in 2026: the annual caps, the fact that top-ups are manual, and the year-end cut-off that decides relief.

Step one: funding your SRS account every month

The first recurring action is the contribution itself. IRAS lets you contribute at any time and as often as you like, up to the annual cap, in cash and in Singapore dollars. Relief is based on the total you put in during the calendar year, so 12 top-ups of S$1,275 earn the same deduction as one top-up of S$15,300.

What you cannot easily do is put the top-up on autopilot. OCBC does not offer standing instructions for SRS contributions, and the contribution guides at DBS and UOB describe one-off transfers through the app, internet banking, a branch or a cheque. In practice, a monthly plan means logging in once a month and making the transfer yourself. UOB SRS contributions cannot be made through other banks' internet or mobile banking, so your salary needs to reach the operator bank first.

A calendar reminder on payday is the simplest fix. Pair it with step two so the money gets invested soon after it lands.

Two separate monthly steps in an SRS regular savings plan: top up the SRS account, then invest through a recurring buy order

Monthly amounts if you start part-way through the year

The S$1,275 and S$2,975 figures assume you start in January. If you begin later and still want to reach the full cap, the monthly amount rises because fewer months remain. Starting now, in late October 2026, leaves November and December.

Example only, based on IRAS SRS contribution caps (as of 18 October 2026). Assumes equal top-ups from the first month shown to December.

Reaching the cap is optional. A smaller monthly amount still earns relief on whatever you contribute, and unused room simply lapses at year-end. Foreigners need to file the Declaration Form for SRS (For Foreigners) every year before the higher cap applies, so a January plan should start with that declaration.

Step two: investing your SRS cash every month

The second recurring action is the investment. Here automation is common, but each provider runs its own plan with its own rules on what you can buy, how much, and when the order executes. MOF allows SRS money to go into shares, unit trusts, bonds, fixed deposits, ETFs and certain life insurance products, and investment returns stay untaxed until withdrawal.

Most monthly SRS investing in Singapore runs through one of three routes, and they differ mainly in what you can buy and how fees are charged.

Route 1: SGX ETF and blue-chip plans

Bank and broker plans buy SGX-listed counters on a fixed date each month. OCBC's Blue Chip Investment Plan (BCIP) is one of the few that accepts SRS money directly: you can fund it from your OCBC SRS account, starting at S$100 a month. The counter list includes SGX-listed ETFs such as the Lion-Phillip S-REIT ETF and an STI ETF, alongside blue-chip shares like DBS, Singtel and Singapore Exchange.

The standard fee is 0.3% of the amount invested or S$5 per counter, whichever is higher, and SRS purchases carry an extra S$0.35 CDP fee plus GST per counter. Purchases execute on the 22nd of each month, or the next business day if the 22nd is not one. An application received by 12pm on the last business day of a month is processed for execution on the 22nd of the following month, so allow up to seven weeks before the first purchase.

Not every broker plan takes SRS money. CPF and SRS funds cannot be used for the POEMS Share Builders Plan, even though the plan invests monthly in SGX counters. At POEMS, only SGX-listed securities settled in Singapore dollars are eligible for SRS investments, which is a common restriction at local brokers. Check the plan's own terms for "SRS" before you sign up.

Route 2: managed portfolios

Managed portfolios take your SRS cash and invest it in a ready-made mix of funds or ETFs, rebalancing for you. Robo-advisers such as Endowus and Syfe offer selected portfolios that accept SRS money, and POEMS offers its SMART Portfolio for SRS investors from S$300. Costs usually come as an annual percentage of assets, plus the expense ratios of the underlying funds.

Unit trust regular savings plans work in a similar way. OCBC offers more than 60 funds that can be bought with SRS money, with monthly investments from S$100 through a regular savings plan, or a lump sum from S$1,000. Fund sales charges and expense ratios vary widely, so compare the total annual cost of each fund.

The key question for any managed route is how the monthly cash gets there. Some providers pull a recurring amount from your SRS account once you authorise it; others need a fresh instruction each time.

Route 3: ETF platforms with recurring orders

The third route lets you pick individual ETFs and schedule a buy order each month. Some platforms let SRS money reach US-listed and Ireland-domiciled UCITS ETFs as well as SGX listings, which widens the choice to broad global and S&P 500 index funds. Fees tend to be charged per order, either as a flat amount or as a percentage with a minimum.

Two details decide whether this route suits a monthly plan. The first is whether the platform supports recurring orders for SRS money, which can differ from what it offers cash accounts. The second is the per-order fee, because a monthly plan pays it 12 times a year.

How dollar-cost averaging works with SRS

Investing a fixed amount at regular intervals is called dollar-cost averaging (DCA). Because the amount stays the same, you automatically buy more units when prices are low and fewer when they are high. Over a year, that pulls your average cost per unit below the simple average of the prices you paid.

Say you invest S$1,275 a month in an imaginary fund whose price slides from S$10.00 to S$8.00 by April, then recovers, peaking at S$11.00 in September and finishing the year at S$10.50.

Example only, based on the IRAS S$15,300 contribution cap (as of 18 October 2026). Assumes made-up prices, fractional units and no fees.

The S$15,300 bought 1,592.38 units, an average cost of S$9.61 a unit, while the simple average of the 12 prices was S$9.69. At the December price of S$10.50, the holding would be worth S$16,719.97. A January lump sum at S$10.00 would have bought 1,530 units, and a December lump sum only 1,457.14.

Dollar-cost averaging example: units bought each month with S$1,275 as the price changes

The result depends entirely on the price path. If the same fund had risen steadily from S$10.00 to S$12.00 over the year, monthly purchases would have bought only 1,395.46 units, fewer than the 1,530 from a January lump sum. In a rising market, DCA can trail a lump sum. Its real job is to spread your entry prices, remove the need to pick a day, and turn SRS investing into a habit.

What monthly SRS investing costs against a lump sum

Monthly investing means 12 orders a year instead of one, so the fee structure matters more than it first appears. Flat fees per order grow with the number of orders, while percentage fees with a minimum hit small orders hardest. Across S$15,300 invested in a year, the gap between fee models is wide.

Example only. Flat US$1 fee from ETF Explorer pricing; 0.3% with S$5 minimum from the OCBC Blue Chip Investment Plan (as of 18 October 2026). Assumes S$1.30 per US$1 and excludes GST, FX spreads, CDP fees and fund expense ratios.

Under the 0.3% model, each S$1,275 order would cost S$3.83 at the percentage rate, so the S$5 minimum applies every month and the annual bill reaches S$60. Under the 0.1% model, the S$10 minimum applies to every monthly order, which makes the monthly plan cost eight times the lump sum. A flat per-order fee of US$1 stays small at either frequency.

Fees for 12 monthly SRS orders against one lump-sum order under three fee models

Minimum fees matter even more at small amounts. A S$100 monthly purchase under a S$5 minimum pays 5% of each order in commission before any other charge, which is why low monthly amounts suit plans with flat or low per-order fees. For managed portfolios, the order count matters less, because costs come from the annual management fee and fund expense ratios.

The cost of leaving SRS cash uninvested

Every month a plan skips, the contribution sits in SRS as cash. At 0.05% a year at DBS, a full S$15,300 left idle for a year earns about S$7.65, and a foreigner's S$35,700 about S$17.85. That is the cash drag of an SRS account that is funded but never invested.

A monthly plan reduces this drag in two ways. Each top-up is invested within days or weeks of landing, and the routine makes it harder to forget the balance entirely. The gap between top-up and purchase still exists, especially when a plan executes on a fixed date such as the 22nd, so time your contribution a few days before the plan's cut-off.

Some investors hold SRS cash on purpose, and SGD deposits placed under SRS are covered by deposit insurance up to S$100,000 per depositor per bank. The point is to hold cash by choice.

Year-end timing: relief follows the contribution date

SRS tax relief follows the contribution date. IRAS requires contributions to be made by 31 December, or by your operator's earlier cut-off, to count for the following Year of Assessment, and relief is granted only if you are a tax resident for that YA. Whether you invest the money by then makes no difference to the deduction.

For 2026, the online cut-offs on Thursday 31 December are 7pm for DBS digibank, 7pm for UOB TMRW and 11:59pm on the last business day for OCBC. A December top-up that misses the cut-off counts towards 2027 and YA 2028 instead.

Two practical points follow for monthly investors. Your last top-up of the year should land well before the cut-off, even if the plan's December purchase happens later or in January. And if your plan ever pushes contributions over the cap, DBS refunds the whole contribution, including the part within the cap, so track your year-to-date total and stop topping up once you reach the limit.

Lump sum in December or monthly through the year?

Many investors contribute a single lump sum in December, once they know their income for the year. Others spread contributions monthly from January. Neither approach reliably produces better returns, so the choice comes down to which trade-offs suit you.

Liquidity deserves weight. Withdrawals before your prescribed retirement age are fully taxable and carry a 5% penalty, so a monthly plan only makes sense with money you can leave untouched for years. Some investors split the difference: a modest monthly amount through the year, then a December top-up to fill the remaining room once income is clear.

What to invest in through an SRS plan

The right mix depends on how many years remain before you plan to withdraw. Your prescribed withdrawal age is the statutory retirement age when you first contribute, which is 64 for first contributions from 1 July 2026.

Twenty or more years to withdrawal

A long horizon can absorb more volatility, so many investors at this stage hold mostly diversified equity ETFs or portfolios. Monthly purchases suit this phase well, because there are many years of contributions to spread across market cycles. Expect sharp falls along the way, and plan to keep buying through them.

Five to fifteen years to withdrawal

A balanced mix of global equities and bonds lowers the swings while keeping some growth. Rebalancing becomes more important as the balance grows, either through a managed portfolio or by adjusting which ETFs your monthly order buys.

Less than five years to withdrawal

As withdrawal approaches, money you plan to take out in the first few years can shift towards lower-risk assets such as deposits, government securities or short-duration bonds. Bond funds can still lose value, so match each holding to when you expect to need the cash.

How to set up an SRS regular savings plan

Seven steps set up both recurring actions. Complete them in order, since the investment plan has nothing to buy until the first contribution arrives.

1. Open or confirm your SRS account. You can hold only one SRS account at any time, with DBS/POSB, OCBC or UOB.
2. Choose your monthly amount. Divide your target annual contribution by the months left in the year, and check it against your expected chargeable income and the S$80,000 overall personal relief cap.
3. Pick the investing route. Decide between an SGX plan, a managed portfolio or an ETF platform, based on what you want to hold and the fee per order at your monthly amount.
4. Link SRS to the provider. Give the provider your SRS account details and authorise it to debit your SRS account for each purchase.
5. Set the schedule. Choose the investment, amount and date. Set your bank top-up a few days before the plan's execution or cut-off date.
6. Make the first top-up and check the first purchase. Confirm the contribution reaches SRS and the order executes as expected.
7. Add a monthly reminder. Since top-ups are manual, a recurring calendar reminder on payday keeps step one on track.

Monthly and yearly checklist

A short review keeps the plan working. Each month, check that:

• the top-up was credited to your SRS account;
• the investment order executed and shows on your statement;
• no cash is building up in SRS without a plan for it.

Each year, before December:

• confirm your year-to-date contributions and remaining room under the cap;
• if you are a foreigner, confirm your declaration for the year is on file;
• make the final top-up well ahead of your bank's cut-off;
• review fees, portfolio drift and whether your mix still matches your years to withdrawal.

Frequently asked questions

These are the questions investors most often ask before setting up a monthly SRS plan.

Can I invest my SRS money every month automatically?

The investment step can be automated through a provider's recurring plan, but the contribution step usually cannot. OCBC does not offer standing instructions for SRS contributions, and DBS and UOB top-ups are one-off transfers, so you make each monthly top-up yourself.

Can I start an SRS regular savings plan with S$100 a month?

Yes. OCBC's Blue Chip Investment Plan and its unit trust regular savings plans both accept SRS money from S$100 a month. Under a S$5 minimum fee, though, a S$100 order pays 5% in commission, so check the fee at your monthly amount.

Do I need to invest my SRS contribution before 31 December to get tax relief?

No. Relief depends on the contribution being credited to your SRS account by your bank's cut-off. You can invest it in January or later, though cash left idle at DBS earns only 0.05% a year.

What happens if my SRS cash balance is too low for the monthly purchase?

The provider will usually skip or fail that month's purchase, depending on its rules. Make the bank top-up a few days before the plan's execution date, and keep a small buffer in the SRS account to cover fees.

Can I pause or stop my SRS plan without a penalty?

Yes. Pausing a plan only stops new purchases, and the money and investments stay inside your SRS account. The 5% penalty applies only to withdrawals taken out of SRS before your prescribed retirement age.

Can I use SRS for a broker's monthly share plan?

Only if the plan accepts SRS. POEMS, for example, does not allow CPF or SRS funds in its Share Builders Plan, while OCBC's Blue Chip Investment Plan does. Read the plan terms before signing up.
