CAGR Is The Number That Matters
There's a version of this story that happens thousands of times a year — in Singapore, and in every market where fund marketing exists.
Everything else on that marketing sheet is a choice.
There's a version of this story that happens thousands of times a year — in Singapore, and in every market where fund marketing exists.
Someone sits across from whoever is selling the fund — an agent, an adviser, a representative at a bank counter. The brochure is well-designed. The numbers are in bold. One of them is large. And that large number is the one the conversation is built around.
Performance numbers are rarely wrong. They are simply chosen.
That number is almost never CAGR.
What CAGR Actually Tells You
CAGR — Compound Annual Growth Rate — answers a single question: if your investment grew at a perfectly steady rate every single year over the full period, what would that annual rate be?
The formula is straightforward:
CAGR = (Ending Value ÷ Beginning Value)^(1/n) − 1
Where n is the number of years.
CAGR = (Ending Value ÷ Beginning Value)^(1/n) − 1
Where n is the number of years.
It doesn't care about your best year. It doesn't care about your worst. It compresses the entire journey into one honest number — what your money actually compounded at, start to finish.
That's why it's the right number to anchor on. And that's why it's rarely the first number you're shown.
On most fund factsheets, this is the number listed under "annualised return" — not the cumulative figure. If you can't find CAGR explicitly, "annualised" is the term to look for.
The Performance Window Problem
Every fund has a history. What gets highlighted in a presentation is almost never the full history — it's the most flattering slice of it.
This is legal. It's also common practice. A fund that had a strong recent run will prominently feature that period. The longer, quieter stretch before it tends to live in the appendix — if it appears at all.
It isn't dishonest. But it is selective. And understanding that is the first step to reading any fund presentation clearly.
The human brain responds to large numbers. A strong 1-year or 3-year return triggers something visceral — it feels like opportunity. What it doesn't naturally trigger is the follow-up question: what did the full 10 years actually look like?
When the Number Doesn't Say What You Think
Consider a bond fund — the type often described as "low to medium risk, fixed income" and sold through agent channels as a conservative choice. The publicly disclosed numbers for one such fund available in Singapore tell a useful story.
The number that leads on the marketing sheet:
An Asian Bond Fund — Marketed as Low to Medium Risk
| 1 Year | 3 Years | 5 Years | 10 Years | |
|---|---|---|---|---|
| Fund (cumulative) | +5.7% | +15.2% | +11.9% | +37.7% |
The 10-year cumulative return of 37.7% is the number that leads. In absolute terms, it looks reasonable. But run it through the CAGR formula:
(13,770 ÷ 10,000)^(1/10) − 1 ≈ 3.25% per year
Buried further in the factsheet — if it appears at all — is this:
| 1 Year | 3 Years | 5 Years | 10 Years | |
|---|---|---|---|---|
| Fund (annualised) | +5.7% | +4.8% | +2.3% | ~3.25% |
That's the actual rate at which money compounded over the decade. For the SGD share class — the version a Singapore retail investor would hold — the fund's own factsheet puts the 10-year annualised figure closer to 2.2% per year. Factor in a front-end sales charge of up to 3%, and the investor's actual CAGR sits closer to 1.9%.
By comparison: CPF Ordinary Account — 2.5%, guaranteed, risk-free, no agent required. Not as an alternative investment, but as a benchmark for what patient, zero-effort capital preservation looks like.1
None of this is hidden. It's in the factsheet, for anyone who knows to look and how to read it. The annualised figures sit in a secondary table, below the larger cumulative numbers that lead the page.
That gap — between what leads and what's buried — is exactly where CAGR does its work

When the Same Lens Works in Your Favour
The same logic applies in reverse — and this is the more useful takeaway.
Consider the Amova Singapore STI ETF (G3B.SI)2 — a passive index tracker available on local platforms. Here's what the fund listing shows prominently:
- 1-year performance: +29.22% *
- 3-year annualised: +19.79%
Both accurate. Both doing selective work.
*The 1-year figure is a trailing 12-month return as of the date of publication — it spans across calendar years, which is why it doesn't map directly to any single column in the table below.
The full annual return history tells a more complete story:3
| Year | 2016 | 2017 | 2018 | 2019 | 2020 | 2021 | 2022 | 2023 | 2024 | 2025 |
|---|---|---|---|---|---|---|---|---|---|---|
| Return | +2.76% | +21.25% | −6.67% | +8.88% | −7.75% | +12.25% | +7.52% | +4.35% | +23.01% | +27.97% |
The 10-year CAGR: 10.41% per year.3
That's a respectable result — and for what it is, a low-cost passive STI tracker, it's a fair outcome. Notice the shape of the journey though. Four negative years in fifteen. Three strong consecutive years at the end pulling the short-window numbers up sharply. The 3-year annualised figure of ~19% is partly a product of when you're measuring, not a stable reflection of what this fund delivers across a full cycle.
An investor who entered after seeing "+29% last year" and expected that going forward would be calibrating to the wrong number. The CAGR of 10.41% — measured over the full available history — is the honest anchor.
The fund itself is a reasonable product. It's the framing of any single window that misleads — and CAGR is what cuts through it, in both directions.
The One Number Worth Holding
Every fund factsheet carries the same line: past performance is not indicative of future performance. We read it. We accept it. We sign anyway.
And that's not irrational — investing always requires a bet on an uncertain future. But if past performance can't guarantee what's ahead, it can still tell us something true about what already happened. How a fund actually compounded money, through good years and bad, across a full market cycle — that's real. It occurred. It's on the record.
A fund that returns +29% one year and −7% the next hasn't failed. Markets move in cycles. What matters isn't year-to-year smoothness — it's whether the long-run CAGR is competitive given the risk you're taking and the fees you're paying. A fund that swings wildly might still deliver a solid decade. A fund that posts quietly "moderate" annual returns while charging 2% in annual fees might compound your money at less than 3% in real terms. The headline number tells you about one window. The CAGR tells you about the whole cycle.
CAGR is simply the most honest way to read that record. It doesn't promise the future. It doesn't pretend the past was smooth. It just tells you what the full journey actually delivered — one number, no window chosen, no flattering slice selected.
If we're going to base any part of our forward expectations on history — and we inevitably will — that's the number worth starting with.

A Brief Personal Note
I came close to signing one of these products early in my working life. The agent was good. The brochure was convincing. What stopped me wasn't sophistication — it was one question I happened to ask: "Can you show me the 10-year return?"
The number wasn't impressive. The conversation moved on quickly. I didn't sign.
That question costs nothing to ask.
Before You Sign
Before committing to any fund over a meaningful time horizon — and 10 years is a meaningful time horizon — these are the questions worth sitting with.
What is the 10-year CAGR, annualised, net of ongoing fees? Not the cumulative figure. Not the 3-year window. The full-period annual rate.
What is the entry cost? A 3–5% front-end load is a permanent drag on your starting capital. It doesn't appear in the fund's return figures — it comes out of your pocket before the clock starts.
How does it compare against the risk-free rate? If a conservative product is delivering less than a guaranteed floor rate — CPF, T-bills, or equivalent — after fees and charges, the math is worth a second look.
And what does the number look like across the full cycle — not just the recent run? A 3-year figure measured after three strong years tells you about those three years. The 10-year CAGR tells you about everything else.
That's the number. Everything else is context at best, and selection at worst.
