Is Your Savings Interest Actually Losing Money? (Nigeria Inflation Guide)

Note: This article is for education only and is not financial advice. Rates, fees, and inflation change over time. Always check official terms and consider your own risk.

You see a Nigerian bank or fintech app advertising “high interest” on a savings plan. It sounds like a fantastic deal, right? Your balance will grow!

But wait. Before you lock your funds, there's a hidden thief you need to know about: Inflation.

In Nigeria, where everyday prices can change quickly, a “good” interest rate can still leave you poorer in real terms. This is what economists call the Real Interest Rate Trap.

The Illusion of High Interest Rates

Let's break it down with a simple example. (The numbers below are illustration only.)

Imagine you have ₦100,000 today.

• You deposit it in a savings product earning 10% in a year.
• After one year, you will have ₦110,000.

On paper, you made a ₦10,000 profit. Great!

However, if prices rise by 15% over the same period:

• Something that costs ₦100,000 today may cost ₦115,000 next year.

The Result:

• You have ₦110,000 in your account.
• But you need ₦115,000 to buy the same item you could have bought a year ago.
• Your Real Purchasing Power has decreased by ₦5,000.

Even though your bank balance went up, your ability to buy things went down. This is why "saving in Naira" for the long term is difficult.

Nominal Rate vs. Real Rate

This brings us to the most important formula for Nigerians:

Real Interest Rate ≈ Nominal Interest Rate - Inflation Rate

• Nominal Rate: The number the bank/app advertises.
• Inflation Rate: The rate at which prices are rising.
• Real Rate: What you actually earn in purchasing power.

If your Real Rate is negative, you are losing purchasing power over time by keeping money in that account.

How to Protect Your Money in Nigeria?

If standard savings accounts aren't enough, what can you do?

1. Understand the “true return” before you commit

Before locking money, check:

• Are there fees, withdrawal penalties, or conditions?
• Is the rate fixed, or can it change?
• Is the product regulated and transparent about total cost?

2. Diversify (without taking blind risk)

Some people diversify across safer, regulated options (for example: different savings products, business cashflow buffers, or other assets). The key is to understand risk, liquidity, and fees before you move money.

3. Be careful with “high-yield” promises

Anything that claims returns far above the market often comes with higher risk. Avoid products you don’t understand, and be cautious of hidden fees, aggressive marketing, or unclear terms.

How to Use the Inflation Calculator (Quick Guide)

Use the calculator to answer a simple question: “How much buying power will my money lose over time?”

1. Open the Inflation Calculator.
2. Enter your current amount (for example, your savings balance in ₦).
3. Enter an inflation rate estimate (you can use a recent CPI figure or your own conservative assumption).
4. Choose a time period (1 year, 3 years, 5 years, etc.).
5. Read the result as purchasing power, not just account balance.

Tip: If you’re unsure, try two scenarios (a “lower” and a “higher” inflation rate) and compare outcomes.

Where to Check Inflation (Reliable Starting Points)

Inflation changes, so it’s best to use recent, official figures as your starting point. These sources often publish CPI/inflation updates:

• Nigeria’s official statistics agency: National Bureau of Statistics (NBS) — https://nigerianstat.gov.ng
• Central Bank information and publications: CBN — https://www.cbn.gov.ng

If you use a figure from a news headline, double-check the original source and the time period (month-on-month vs year-on-year).

FAQ

“If my real rate is negative, should I stop saving?”

Not necessarily. Many people still keep an emergency buffer in safer, liquid places. The key is to recognise that long-term savings plans should be evaluated in real (inflation-adjusted) terms.

“What matters more: interest rate or fees?”

Both. A product can advertise a good rate but still underperform once you include fees, penalties, or conditions. Always read the terms and compute the effective outcome.

“Is this telling me what to invest in?”

No. This guide is educational. Its purpose is to help you compare “interest vs inflation” and make more informed decisions based on your own goals and risk tolerance.
