Inflation eats savings

Understand why nominal: the number on the statement.

In this lesson

Inflation eats savings is part of Investing Foundations. This preview shows how investment-universe connects to everyday family decisions such as earning, saving, spending choices, goals, approvals, or parent-guided money conversations inside Progress Penguin.

Today’s money mission

Imagine this situation: Inflation: 18%. Your savings account: 5%. You have 1000000 in local currency saved.

What you need to know

Nominal: the number on the statement. Real: what it buys. If your savings earns 8% but inflation is 20%, your real return is −12% — you are losing purchasing power despite positive nominal growth. Real return is what actually matters for wealth building.

Real-life example

Real-life money moment: Inflation: 18%. Your savings account: 5%. You have 1000000 in local currency saved. What happens to your purchasing power in 1 year? The key lesson is: Real return = 5% − 18% = −13%.

Progress Penguin connection

Open the investment simulator and enter your current savings balance. Apply 22% annual inflation over 5 years. Watch the purchasing power column shrink even though the local currency number stays constant. The balance number is misleading; the purchasing power column tells the truth.

Quiz preview

If inflation is 18% and savings pay 5%, your REAL return is:

+13%
+23%
+5%
-13%

Inflation: 18%. Your savings account: 5%. You have 1000000 in local currency saved. What happens to your purchasing power in 1 year?

It stays the same — inflation and interest cancel out when planning ahead
It depends on what you buy given the circumstances as a reliable approach
It falls — you earned 5% (50000 in local currency) but prices rose 18% (180000 in local currency). Real loss: 130000 in local currency in purchasing power
It grows — you earned 5% interest in practical terms as a general rule in this situation
