From 17% to 13%: Why a Falling Return Can Hide a Growing Fortune — and the Comparison Trap a Good Mentor Saves You From

A few days ago, one of our long-term clients sent us a message that we receive, in some form, almost every single week. We are sharing it with his permission and with every identifying detail removed, because the feeling underneath it is universal. He wrote: "Return % has been decreasing continuously for a long period. From 17% it is now only 13%. My mother’s is worse than this. And my sibling’s is only 4% — less than a savings account. They have been investing for four or five years. I have been investing for thirteen." A little later, he added a second thought: "One of my colleagues has been investing without any advisor. His return is now 18%."

If you have ever felt that quiet, sinking feeling — that everyone else’s money is somehow doing better than yours — this article is written for you. And it carries good news, because almost everything that makes that feeling so painful turns out to be a trick of how the human mind reads numbers. Let us take the whole thing apart, gently and honestly, one layer at a time. By the end, the picture usually looks the opposite of how it first felt.

The investor’s chief problem — and even his worst enemy — is likely to be himself. — Benjamin Graham

Trap #1 — A return number with no context is just a rumour

The single most important thing to understand is this: a return percentage, on its own, tells you almost nothing. It is like being told someone "scored 80" without being told 80 in what — a 100-mark test or a 500-mark one, in mathematics or in a spelling bee, after one year of study or ten. A return only becomes meaningful when you attach four things to it: over what duration, in which funds, starting from when, and with how much risk and discipline along the way. Strip those away and you are left with a rumour, not a fact.

Look again at the colleague’s line: "His return is now 18%." Notice everything that sentence does not say. Over what period — one year, three, ten? In what — a diversified portfolio, or one lucky stock, or a single red-hot small-cap fund? With how much concentration and volatility? And, crucially, has that 18% ever been tested by a real market crash, or was it earned entirely inside a rising market that has not yet asked it a hard question? An 18% that has never lived through a 30% drawdown is not the same animal as a 13% that has survived three of them and kept compounding. The number that survives storms is worth far more than the number that has only seen sunshine.

Why 17% quietly became 13% — and why that is not bad news at all

Here is the part that surprises almost everyone. For a 13-year SIP investor, a return falling from 17% to 13% is usually not a sign that anything has gone wrong. It is, more often, a sign that the portfolio has grown up. The number most investors watch is the XIRR — a money-weighted return that blends every rupee you have ever invested, weighted by how long it has been working. In the early years, your corpus is small, so a great market run (like 2020–2024) lifts the whole average sharply. That is how a young portfolio shows a dazzling 17%.

But over thirteen years your corpus becomes large — the sum of more than a hundred and fifty monthly instalments plus all their growth. Now a flat or sideways patch in the market (and Indian equities have been broadly flat for the last 18 months, a stretch we have written about before) acts on a much bigger base. The recent, less-compounded money drags the blended average down from its peak, even as your absolute wealth keeps climbing. The percentage falls while the rupees rise. A 13% annualised return, sustained over thirteen years, on a large and growing corpus, is not a disappointment — it is wealth being built exactly as it is supposed to be. It comfortably beats inflation, fixed deposits, and the savings account his sibling’s 4% was being compared against.

Put plainly: the headline return is a thermometer, not a fuel gauge. It can read a little lower in a flat patch even while the tank — your actual corpus — is fuller than it has ever been. Watching the thermometer and ignoring the tank is how good investors talk themselves into bad decisions.

Why your mother’s and sibling’s numbers cannot be compared to yours at all

The client compared his 13% to his mother’s lower number and his sibling’s 4%, noting that they had invested for "four or five years" against his thirteen. That single difference makes the comparison meaningless — not slightly unfair, but mathematically meaningless. A four- or five-year investor and a thirteen-year investor have lived through entirely different market windows. The thirteen-year investor caught the 2020 crash-and-recovery, one of the great wealth-creating events of a generation. The four-year investor started afterwards and has spent a large slice of their short journey inside the recent flat patch — on a young corpus that has had little time to compound. Same market, completely different experience.

And a 4% number on its own raises questions, not conclusions. Was the money in a conservative, debt-heavy allocation that was never meant to shoot the lights out? Did the SIP start near a market high? Were instalments paused or stopped during a scary stretch — the single most common silent killer of returns? Is it in the wrong fund for the goal? Without knowing when it started, which funds it sits in, and whether the discipline held, the 4% is a symptom with no diagnosis. The honest answer to "why is hers only 4%?" is almost never "the market" — it is usually one of those four context questions, and every one of them is fixable. That is a conversation to have, not a verdict to accept.

The colleague at 18% — and the three biases hiding inside that one sentence

The most corrosive comparison is almost always the colleague, the neighbour, the relative at the wedding who "got 18% on his own." Three well-documented biases hide inside that sentence, and once you can name them, they lose most of their power.

The first is survivorship bias. You hear about the colleague who is up 18%. You do not hear about the three colleagues in the same office who tried the same do-it-yourself approach, bet big on a theme that fizzled, panicked in a correction, and quietly stopped talking about their portfolio. The winners announce themselves; the losers go silent. So the "average self-investor" you imagine is really a highlight reel of the luckiest ones.

The second is recency bias. An 18% that exists "now" usually rests on a recent hot streak — a concentrated bet or a momentum trade that has been working lately. Markets are brilliant at making the recent past feel like a permanent skill. The same portfolio that prints 18% in a friendly market can print a frightening number in an unfriendly one, precisely because the concentration that powered the upside also powers the downside.

The third, and the most expensive, is the behaviour gap. Decades of studies of real investor returns — most famously the long-running Dalbar research in the United States, and echoed in Indian data — show the same uncomfortable result: the typical do-it-yourself investor earns meaningfully less than the very funds they own, because they buy after rallies and sell during crashes. The fund returns one number; the investor, through their own timing, captures a smaller one. A confident "I do it myself and I’m up 18%" very often describes the brief, happy phase before the first real test — the test that quietly converts a paper 18% into a realised single digit.

Gold, silver, and the seduction of last year’s winner

A close cousin of the colleague comparison is the asset that is having a moment. When gold or silver has just had a spectacular run, someone will show you those returns and ask why your equity funds did not do the same. It is the comparison trap wearing a different costume — recency bias pointing at whatever has been hottest most recently. The honest history is sobering: gold has delivered long, flat, real-return deserts — it went roughly nowhere in inflation-adjusted terms across long stretches of the 1980s, 1990s and 2010s — punctuated by occasional sharp rallies that everyone remembers and quotes. Chasing whichever asset just won is the single most reliable way to keep arriving late. A sensible, modest allocation to gold as a diversifier and a shock-absorber is wise; abandoning a goal-aligned equity plan because gold had a good year is the greener-grass mistake in its purest form.

The only scoreboard that actually matters is your own goal

Here is the reframe that dissolves the whole anxiety. Your colleague’s 18%, your mother’s number, gold’s good year — none of them are your scoreboard. They are not running your race. The only question that matters is whether your money is on track to fund your life: the home, the children’s education, the retirement you actually want. A 13% return that comfortably funds your goals is a triumph. A 25% return earned by taking risks that could blow up your goals is a danger dressed as a win. Investing is not a contest you win by beating the person next to you; it is a personal project you win by reaching your own finish line with your nerves — and your capital — intact. The grass on the other side always looks greener because you are seeing their highlight reel and living your own full, unedited footage.

What a good mentor actually does — and why it is a full-time job

This is where a good mentor earns their keep, and it is almost never the thing people imagine. A mentor’s value is not a secret fund that returns 30%, nor a crystal ball for next quarter. The honest, full-time value is behavioural: closing that behaviour gap. It is the steady voice that, in the exact moment you are tempted to abandon a sound plan because a colleague got luckier, helps you see your own numbers in context — the duration, the funds, the timing, the discipline — and keeps you invested through the cycles when the headline return looks dull. The biggest returns in a real investor’s life are not the ones a fund earns; they are the ones a mentor prevents you from giving away by panicking, chasing, or quitting at the wrong time.

A good mentor does the unglamorous work that compounds: anchoring every rupee to a specific goal so progress is measured against your finish line and not a stranger’s; diagnosing a "low" number honestly (was it the start date, the fund, a paused SIP, or simply a flat market doing its temporary thing?) instead of reacting to it; rebalancing without emotion; and, most of all, being there — by name, full-time — in the frightening weeks when doing nothing is the hardest and most valuable thing an investor can do. That is the quiet case for a relationship with a guide whose entire job, every working day, is your family’s financial journey, done with honesty. It is also, candidly, why we believe a serviced, coached relationship is worth its modest cost: the cost is visible and small; the panic it prevents is invisible and large.

What we would actually say to this client

So if you are the client who sent us that message — or you simply feel the way he did — here is what we would say, calmly and specifically. Your 13% annualised over thirteen years, on a corpus that is now large, is not a falling fortune; it is a built one, and the slip from 17% is mostly the maths of a maturing portfolio meeting a flat market, not a flaw in your funds. Your family members’ lower numbers are not a verdict on them — they are an invitation to look, together, at when each started, which funds they hold, and whether the discipline held; almost certainly there is something simple and fixable underneath. Your colleague’s 18% is a sentence missing its context, and the missing context is usually duration, risk, and a crash it has not yet met. And gold’s good year is a reason to hold a sensible sliver, not to abandon a plan that is quietly doing its job.

Stop checking the thermometer and start watching the tank. Measure your money against your goal, not against the loudest number at the dinner table. And if a falling percentage ever makes you want to change a sound plan, that is precisely the moment to call your mentor first — because the costliest mistakes in investing are almost never made by the market. They are made, in a moment of comparison, by us.

If you would like to see your own real picture — your true progress measured against your actual goals, with an honest diagnosis of every number that looks "low" — that is exactly the conversation we exist to have. Reach your Trustner Relationship Manager, or write to us, and we will walk you through it, with no obligation and no jargon.
