Saving in Singapore: the Math That Actually Matters
A savings plan is three inputs and time: what you start with, what you add each month, and the rate the money earns with interest credited on a schedule. This calculator projects all three month by month and shows the year-by-year table so the shape is visible — early years where contributions do the work, later years where interest starts pulling its own weight. The maths is the same everywhere; what changes in Singapore is the menu of places to earn it and the safety net underneath.
With the example inputs — S$10,000 to start, S$500 a month, the illustrative 1.00% rate over 5 years — the plan reaches about S$41,262, of which interest contributes roughly S$1,262. At Singapore deposit-style rates the interest is real but modest; the contributions do the heavy lifting, which is why the honest lever is the amount you add, not the rate you chase. Change any input and the table recomputes instantly — including the compounding frequency, which the terms of your actual product state.
Where Singapore savings actually sit
Singapore savings money lives in several places. Bank savings accounts pay tiered rates that usually rise with balance bands and fall when promotions end. Fixed deposits lock a sum for a stated tenor at a stated rate. Singapore Savings Bonds are government-issued, with rates stepped up by holding period and the first-year interest protected if you exit early — they are designed to reward holding rather than trading. CPF accounts earn interest subject to legislated floors, with the Ordinary Account also serving housing. Every product's current rate is published by the issuer — this calculator deliberately never assumes one, because rates move and a stale figure would quietly mislead.
The SDIC safety net
Deposits with SDIC scheme members — banks and finance companies — are insured up to S$100,000 per depositor per scheme member. The results panel flags it when your projected balance crosses that line, because the honest response is usually simple: split the money across members, or move the excess into instruments whose risk you have chosen deliberately rather than accumulated by accident. Coverage limits are set by SDIC; check their published scheme details for what counts and what does not.
Assumptions worth knowing
Contributions are added at month-end, interest is credited at the equivalent monthly rate for the compounding frequency you select, and the rate is held flat for the whole horizon — no promotional cliffs, no tier changes, no bonus interest conditions. Real accounts do all three, which is why the projection is an estimate, not a promise. The one behaviour that reliably beats the model is the one the model cannot supply: not interrupting the plan.
Frequently Asked Questions
What rate should I enter?
Enter the rate your product actually pays — the effective rate on your savings account tier, your fixed-deposit quote, or the relevant holding-period step of a Singapore Savings Bond. The 1.00% pre-filled is an illustrative example only — NOT a current Singapore market rate.
What happens when my balance passes S$100,000?
The calculator flags that the projection exceeds the SDIC deposit insurance limit of S$100,000 per depositor per scheme member. Above the limit, consider splitting across members or deliberately choosing an investment for the excess — the flag is information, not advice.
Does the calculator model CPF accounts?
No — CPF accounts have their own contribution rules, floors and usage restrictions that this page does not model. You can still use it to project a sum you treat as locked away: enter CPF-level rates only if you accept the simplification that the rate is flat and withdrawals are ignored.
Why is monthly compounding the default?
Most Singapore savings accounts credit interest monthly, so the default matches the most common structure. Fixed deposits typically compound at maturity, and some products credit quarterly — the selector matches whatever your terms say.
