Why is my retirement corpus growing slower than expected?

Your Retirement Planning Guide Feels Broken — Here Is Why

You started early. You put money aside each month. You picked a decent mutual fund. Yet when you check your retirement corpus today, the number feels disappointing. It has not grown the way you expected. You are not alone. Millions of people face this exact frustration.

The good news? The problem usually has a clear cause. And once you spot it, you can fix it. This retirement planning guide will walk you through the most common reasons your corpus lags behind — and what to do about each one.

The Real Pain: Expectations Versus Reality

Most retirement calculators show a smooth upward curve. They assume a fixed annual return — say 12 percent — compounding year after year. Real markets do not work that way. Some years give you 25 percent. Others take away 15 percent. The sequence of returns matters far more than the average return.

Here is a simple example. Suppose you invest 10,000 rupees per month for 10 years.

• Scenario A: Markets rise 15 percent per year for the first 5 years, then fall 5 percent per year for the next 5. Your corpus at the end: roughly 18.9 lakh rupees.
• Scenario B: Markets fall 5 percent per year for the first 5 years, then rise 15 percent per year for the next 5. Your corpus at the end: roughly 16.2 lakh rupees.

Both scenarios have the same average return of 5 percent per year. But the timing of losses changes the outcome by almost 2.7 lakh rupees. This is called sequence risk, and no retirement calculator warns you about it.

Diagnosis: Five Reasons Your Corpus Is Falling Short

Let us break this down. Your retirement fund is probably underperforming because of one or more of these issues.

1. Inflation Is Eating Your Returns

You see 10 percent returns on paper. But if inflation runs at 6 percent, your real return is only about 4 percent. Over 20 years, that gap is massive. A corpus of 1 crore rupees today will need to be 3.2 crore rupees in 20 years just to buy the same things — assuming 6 percent inflation.

Fix: Always think in real returns (after inflation). If your investments earn less than inflation, you are losing purchasing power every single day.

2. You Are Paying Too Much in Fees

A 2 percent annual expense ratio sounds small. It is not. Over 30 years, that 2 percent fee can consume nearly 40 percent of your total wealth. Fund houses do not advertise this because the impact only shows up over decades.

Fix: Compare expense ratios. Index funds often charge 0.1 to 0.3 percent. That difference alone can add lakhs to your retirement corpus.

3. Your Asset Allocation Is Too Conservative

If you are 30 years old and hold 60 percent of your portfolio in fixed deposits or debt funds, your money is barely beating inflation. You have time on your side. Yet you are investing like a retiree.

Fix: A common rule of thumb is to subtract your age from 100. That gives you the rough percentage to hold in equities. At age 30, that means 70 percent in stocks. Adjust based on your comfort, but do not let fear keep you out of growth assets.

4. You Are Not Increasing Your SIP Each Year

You started a SIP of 5,000 rupees per month five years ago. Your salary has gone up by 30 percent since then. But your SIP has stayed the same. This is one of the biggest reasons retirement corpuses fall short.

Fix: Increase your SIP by at least 10 percent each year. This is called a step-up SIP. The impact is enormous:

• Flat SIP of 10,000 rupees per month at 12 percent for 25 years = roughly 1.89 crore rupees
• Same SIP with a 10 percent annual step-up = roughly 3.6 crore rupees

That is almost double the corpus just from annual increases.

5. You Withdrew or Paused During Market Crashes

Every market crash triggers panic. In 2020, many people stopped their SIPs or redeemed their equity funds at the bottom. Those who stayed invested saw a full recovery within 12 months. Those who exited locked in their losses permanently.

Fix: Build a separate emergency fund covering 6 to 12 months of expenses. This buffer stops you from touching your retirement money during tough times.

A Retirement Planning Guide to Get Back on Track

Here is what you should do right now:

1. Calculate your real return. Take your portfolio return and subtract inflation. If the number is below 4 percent, you need to rethink your allocation.
2. Audit your fees. List every fund you hold and its expense ratio. Anything above 1 percent deserves scrutiny.
3. Set up a step-up SIP. Even a 5 percent annual increase makes a big difference over 20 years.
4. Rebalance once a year. Sell what has grown too large. Buy what has shrunk. This forces you to buy low and sell high.
5. Stop checking daily. Weekly or monthly reviews are enough. Daily tracking creates anxiety and leads to bad decisions.

How to Prevent This Going Forward

The biggest enemy of your retirement corpus is not bad markets. It is inaction. People set up a plan once and forget about it for years. Markets change. Your income changes. Your goals change. Your plan should change too.

Review your retirement plan every year. Ask yourself three questions:

• Am I saving enough given my current income?
• Are my investments beating inflation after fees?
• Have I increased my contribution this year?

If you answer no to any of these, fix it that week. Not next month. Not next year. That week.

A retirement corpus does not grow slowly because markets are bad. It grows slowly because small mistakes compound over decades — just like your money should.

You still have time. The gap between where you are and where you want to be is fixable. But only if you act now. Run the numbers. Cut the fees. Increase the contributions. Your future self will thank you.
