What Is a Fixed Deposit in Nigeria?
A fixed deposit (FD) — also called a term deposit or time deposit — is one of the most popular low-risk savings instruments offered by Nigerian commercial banks. When you open a fixed deposit account, you commit a lump sum of money to the bank for an agreed period (the "tenure"), typically ranging from 30 days to 24 months. In return, the bank pays you a predetermined interest rate that is higher than a standard savings account rate.
At the end of the tenure (maturity date), the bank returns your full principal plus the accrued interest. Unlike treasury bills — which are purchased at a discount — fixed deposits are straightforward: you deposit, you earn interest, you collect. This simplicity makes FDs particularly attractive to conservative investors, retirees, and anyone seeking a predictable, capital-preserving investment in Nigeria's high-inflation environment.
Fixed deposits in Nigeria are regulated by the Central Bank of Nigeria (CBN) and are offered by all licensed deposit money banks (DMBs), including GTBank, Zenith Bank, Access Bank, UBA, First Bank, Fidelity, and others. The CBN's monetary policy stance — including the Monetary Policy Rate (MPR) — significantly influences the interest rates banks offer on FDs.
Current Fixed Deposit Interest Rates in Nigerian Banks (2025)
Following the CBN's aggressive rate-hiking cycle that pushed the MPR above 27% in 2024–2025, Nigerian commercial banks have significantly raised their fixed deposit rates. Below are indicative rates for major banks as at mid-2025. Always confirm current rates directly with the bank before investing.
| Bank | 30–90 Days | 180 Days | 12 Months | 24 Months |
|---|---|---|---|---|
| GTBank | 12.0% | 14.5% | 15.5% | 16.0% |
| Zenith Bank | 11.5% | 13.5% | 15.0% | 15.5% |
| Access Bank | 12.0% | 14.0% | 15.0% | 16.0% |
| UBA | 11.0% | 13.0% | 14.5% | 15.5% |
| First Bank | 11.5% | 13.5% | 14.8% | 15.5% |
| Fidelity Bank | 12.5% | 14.2% | 15.2% | 15.8% |
| Sterling Bank | 13.0% | 14.8% | 16.0% | 16.5% |
All rates are indicative as of 2025 and subject to change. Confirm with your bank. WHT of 10% applies on interest earned.
Simple vs Compound Interest — Which Do Nigerian Banks Use?
Understanding the difference between simple and compound interest is critical when evaluating fixed deposit returns in Nigeria.
Simple interest is calculated only on the original principal throughout the entire tenure. Formula: Interest = Principal × Rate × Time. Most Nigerian commercial banks — including GTBank, Zenith, Access, and UBA — apply simple interest on fixed deposits. A ₦1,000,000 deposit at 15.5% for 12 months earns exactly ₦155,000 in gross interest.
Compound interest earns "interest on interest." The interest is periodically added to the principal, and subsequent interest is calculated on the new, larger balance. Our calculator uses quarterly compounding (4 times per year), which is the most common compounding frequency when Nigerian banks do offer it. The same ₦1,000,000 at 15.5% compounded quarterly yields approximately ₦163,200 — about ₦8,200 more than simple interest.
For short tenures of 30–90 days, the difference between simple and compound interest is negligible. The gap widens significantly for 12-month and 24-month deposits. Always ask your bank whether they compound interest and at what frequency.

Benefits of Fixed Deposits in Nigeria
- Capital preservation — Your principal is guaranteed and returned in full at maturity, regardless of market conditions.
- Predictable returns — The interest rate is locked in at the time of deposit, so you know exactly what you will earn before you invest.
- NDIC deposit protection — The Nigeria Deposit Insurance Corporation (NDIC) protects deposits at licensed banks up to ₦5 million per depositor per bank. This provides a safety net not available with many other investment types.
- Flexible tenures — Nigerian banks offer a wide range of tenures, from as short as 30 days (for those who need near-term liquidity) to 24 months for those who can lock in capital longer.
- Easy to open — Fixed deposits can be opened at any bank branch or increasingly through mobile banking apps, with minimal documentation required for existing customers.
- Higher rates than savings — FD rates are consistently 2–5 percentage points higher than standard savings account rates in Nigeria, making them an important step up for conservative investors.
Fixed Deposit vs Treasury Bills vs Savings Bond
Nigerian investors have three main low-risk fixed-income options. Here is how they compare:
| Feature | Fixed Deposit | Treasury Bills (NTB) | FGN Savings Bond |
|---|---|---|---|
| Issuer | Commercial Banks | Federal Govt (CBN) | Federal Govt (DMO) |
| Typical Rate (2025) | 13–16% p.a. | 18–22% p.a. | 18–19% p.a. |
| Minimum Investment | ₦10,000+ | ₦50M (primary) | ₦5,000 |
| Tenor | 30d – 2yr | 91d / 182d / 364d | 2yr or 3yr |
| Withholding Tax | 10% on interest | Tax-exempt | Tax-exempt |
| Interest Payment | At maturity | Upfront (discount) | Quarterly coupon |
| NDIC/Govt Guarantee | NDIC (₦5M limit) | Federal Govt | Federal Govt |
| Liquidity | Low (early withdrawal penalty) | Secondary market | Secondary market |
The key insight: NTBs and FGN Savings Bonds are tax-exempt, meaning their gross rates are effectively higher on a net basis compared to fixed deposits where 10% WHT applies. However, NTBs require larger capital through primary market auctions, making FDs and FGN Savings Bonds more accessible for retail investors.
Frequently Asked Questions
Can I break a fixed deposit early in Nigeria?
Yes, most Nigerian banks allow early withdrawal of fixed deposits, but this typically incurs a penalty. The bank usually reduces your interest rate (sometimes to savings rate level) and may charge a flat fee. Always check the early liquidation terms before placing your FD.
What is the minimum amount for a fixed deposit in Nigeria?
Minimum FD amounts vary by bank. Many banks accept deposits from as low as ₦10,000–₦50,000 for standard accounts. Some premium or high-yield FD products require ₦500,000 or more. Check with your specific bank for their current minimums.
Are fixed deposits at Nigerian banks safe?
Fixed deposits at CBN-licensed deposit money banks are considered among the safest investments in Nigeria. They carry NDIC protection up to ₦5 million. For amounts above this limit, the safety depends on the financial health of the specific bank.
How does withholding tax affect my FD returns?
FIRS applies a 10% withholding tax on interest income earned from bank fixed deposits. For example, if you earn ₦155,000 gross interest, the bank deducts ₦15,500 in WHT, leaving you ₦139,500 net. Our calculator shows gross figures — factor in 10% WHT for your actual take-home.
When is the best time to lock in a fixed deposit in Nigeria?
When the CBN is in a rate-hiking cycle (rising MPR), locking in a longer-tenor FD early is often wise — you secure today's high rate before banks lower offers. When rates are peaking or the CBN is cutting, shorter tenures (30–90 days) give you flexibility to reinvest at better rates as they evolve.
