Financial Literacy

Investing, Compounding & Inflation Awareness

Lesson

Why This Lesson Matters

Saving keeps your money safe. Investing helps your money grow. In Sri Lanka, prices rise over time. If your money grows slower than prices, you are actually moving backward. Investing is how you push forward—carefully, slowly, and with a plan. This lesson explains how growth works, why compounding is powerful, and how inflation affects your choices. You will learn simple first steps that fit real life: small amounts, steady habits, and low drama.

Think of a coconut sapling. On day one it looks like nothing. With time, water, and protection, it becomes a tree that gives for years. Investing is the same. You won’t see much in the first month. But with patience and discipline, small steps add up.

“Don’t aim for fast money. Aim for steady growth.”

Step 1: What Investing Is—and Why Compounding Matters

Investing means putting money into assets that can grow or pay you income over time. It is different from saving. Saving is about safety and quick access (your buffer, short-term goals). Investing is about growth and patience (goals you don’t need for years).

The engine of investing is compounding—earning returns on your returns. When you reinvest what you earn, the amount grows faster than simple savings. Early on it feels slow. Later it feels surprising. Time is the secret ingredient.

A helpful shortcut is the Rule of 72. Divide 72 by the annual return (%) to estimate how many years it takes to double your money. If an investment averaged 8% per year, 72 ÷ 8 ≈ 9 years to double. This is only a rough guide, but it shows why starting early matters. More years = more doubling periods.

Now add inflation to the picture. Inflation is the rise in prices. If prices rise 10% in a year and your money grows 6%, your real return is roughly 6% − 10% = −4%. You gained numbers but lost purchasing power. That is why long-term money needs a chance to grow faster than inflation—on average, over time.

This does not mean chasing high-risk bets. It means using simple, diversified options and staying invested through ups and downs. Some years will be flat or negative. Over many years, discipline usually wins. Investing is a marathon, not a sprint.

“Time in the market beats timing the market.”

Before you invest, check your base:

  1. Emergency fund in place (Lesson 6).

  2. Harmful debt under control (Lesson 7).

  3. A budget that lets you invest a small, regular amount (Lesson 4).
    If these are ready, you can start—small is fine.

Step 2: Simple First Steps (Low Drama, Realistic, Repeatable)

Start with long-term goals: education fund, a professional course, a business you want to launch in three years, retirement comfort for your parents, or your own future. Write the time horizon next to each goal: short (<3 years), medium (3–7 years), long (7+ years). As a rule of thumb, invest only money you won’t need for 3+ years. Short-term money belongs in savings.

Next, choose simple vehicles that match real life. The goal is to get started and keep going:

  • Bank fixed deposits (FDs)/term deposits: lower risk, predictable, but returns can be close to inflation. Useful for medium-term goals you can’t risk losing.

  • Government securities (Treasury bills/bonds via your bank or a fund): backed by the state; generally higher than savings accounts and relatively low risk for long-term savers who can handle price swings if sold early.

  • Unit trusts / index funds: your money is pooled and invested across many assets (e.g., government securities, corporate bonds, or shares). Diversification lowers the impact of any one part falling. Look for clear fees and simple strategies.

  • Gold: can protect against currency weakness and inflation, but prices move up and down. Consider small, disciplined amounts if you understand the risks and costs.

  • Your own skills or micro-business: a sewing machine, a course that raises your hourly rate, a tool that earns. This is also an investment—in yourself.

Avoid what you don’t understand. If something promises guaranteed high returns, asks you to recruit others, or pushes you to “decide today,” step away. No legitimate investment needs hurry and secrecy.

Build a standing order (automatic transfer) the day income arrives. This is rupee-cost averaging: you invest the same amount regularly regardless of market levels. When prices are low you buy more units; when prices are high you buy fewer. Over time, this evens out. Automating removes emotion and forgetfulness.

Keep your eyes on costs. Fees reduce returns. A small percentage fee, paid every year, can quietly eat a big chunk over decades. Choose simple products with transparent, low fees.

Finally, set behavior rules:

  • Don’t check prices every day. Review once a month or once a quarter.

  • Don’t sell just because prices dip. Ask, “Did my goal or time horizon change?” If not, stay the course.

  • Rebalance once or twice a year if one asset grew too big.

Increase your monthly investment when income rises—capture half of the raise for three months.

The Golden Rule

Emergency fund first. Invest only what you won’t need for 3+ years, in simple, low-fee options you understand.

Exercises: Your Turn to Grow

Exercise 1 — Readiness Check. Write three ticks: Buffer ready? High-interest debt under control? Budget set? If any are “no,” fix those first. Investing is stage after safety.

Exercise 2 — Goals & Time Horizons. List two long-term goals (7+ years) and one medium-term goal (3–7 years). Write the year you’d like each one funded. This gives your investments a job.

Exercise 3 — Rule of 72 (Practice). Using the Rule of 72, estimate doubling time at 6%, 9%, and 12%. Write: “At 6% ≈ 12 years; at 9% ≈ 8 years; at 12% ≈ 6 years.” This shows the power of time and realistic returns.

Exercise 4 — Set a Standing Order. Choose an amount you can invest every payday (even LKR 1,000). Set an automatic transfer to your chosen vehicle (e.g., a government-securities fund or FD for now). Do it on payday so you don’t “spend first, invest later.”

Exercise 5 — Inflation Awareness. Pick five items you buy often (rice, dhal, milk powder, eggs, bus fare). Write today’s price. Ask a parent/grandparent last year’s price, or check old receipts. Note the change. This is inflation. Keep this list and update it every three months.

Exercise 6 — Red-Flag Filter. Write three rules: “No guaranteed high returns,” “No rush or secrecy,” “No investing in what I don’t understand.” Keep this next to your workspace. If an “opportunity” breaks any rule, walk away.



Quick Win

Set a standing order for LKR 1,000 on payday to your chosen vehicle. Do one fee check today: note the actual % fee or penalty on that product.

Common Roadblocks (and Simple Fixes)

“I can only invest tiny amounts.” Perfect. Compounding loves time and consistency, not size. LKR 1,000 a month for years is better than LKR 20,000 once. Start now.

“Markets go up and down. I’m scared.” True—and normal. That is why you invest only long-term money and use rupee-cost averaging. You are buying time in the market, not a perfect entry day.

“I don’t know what to choose.” Start with a safer base (FD or government-securities fund) while you learn. Read a simple fact sheet. Understand the fee. Add a small diversified fund later when comfortable.

“Family says investing is gambling.” Investing is not gambling when you use simple, diversified options, small regular amounts, and a long horizon. Show them your buffer, your plan, and your automation. Calm beats noise.

“I got a hot tip.” Be polite and decline. If it sounds too good to be true, it is. Your future is not a place for experiments you don’t understand.

Keeping Yourself Motivated

Make growth visible. Draw a small investment ladder and color a step each month you invest. Celebrate streaks: 3 months, 6 months, 12 months. Review your plan once a quarter, not every day. If you increase your income (Lesson 2), raise your standing order by a small amount and write down the date. Connect your investments to your goals: a course fee paid without stress, a tool that lifts your earnings, or a future where you can support your family with dignity.

“Let time and discipline do the heavy lifting.”



Your First Step is Complete

You now understand the basics of investing, the power of compounding, and how inflation affects your real progress. You have a simple order of operations: buffer first, debt controlled, budget set, then invest small and regular in options you understand. Use automation. Keep fees low. Review calmly. Grow steadily.

Start today: confirm your readiness, write your goals and horizons, set a small standing order, and do a quick fee check. Tell one family member your plan so they can cheer you on. This is how prosperity grows—quietly, clearly, and with discipline.
