Where to invest in Nigeria
NGX All-Share long-term ≈ 15–20% (nominal, NGN). Many investors use USD funds via Cowrywise, Bamboo to hedge inflation.
Returns are long-term historical averages, not guarantees - markets fall as well as rise. Invest for the long term and diversify.
The power of compounding
Investing ₦150,000 per month for 15 years at 11% p.a.:
- Future value: ₦68,828,634
- Total invested: ₦27,000,000
- Estimated gains: ₦41,828,634
That is roughly 2.5× your money - most of it from compounding. Scale the ₦150,000 to your own monthly amount, and remember that starting earlier matters more than investing more.
How to start - and stay - invested in Nigeria
- Automate a fixed monthly amount so you invest through good months and bad.
- Start small; you can raise the amount as your income grows.
- Favour low-cost, diversified funds over picking individual stocks.
- Stay invested through market dips - time in the market beats timing the market.
A real-data rate check: long-term returns in Nigeria (2026)
Long-run data on the Nigerian Exchange (NGX) All-Share Index shows it is realistic for a diversified Nigerian equity portfolio to compound in the low-to-mid teens over long stretches — but not the 18% a year some calculators assume by default. An independent analysis of NGX performance found the index delivered a cumulative return of over 147% from 2014 to 2023, which works out to roughly 10.6% per year compounded (CAGR) over that nine-year stretch. Some individual years have been far higher (the NGX All-Share Index gained about 37.65% in 2024 and around 51% in 2025), but those spikes were driven largely by the naira's sharp devaluation and a surge in consumer prices after 2023 reforms, not by a sudden jump in the real value of Nigerian companies.
That inflation point matters a lot in Nigeria. The Central Bank of Nigeria (CBN) has been paying around 17.34% on 364-day Treasury Bills, while the National Bureau of Statistics (NBS) reported headline inflation easing to 15.39% in August 2026. When inflation and risk-free interest rates are both running in the mid-to-high teens, a nominal equity return anywhere near 18% is delivering only a modest real (inflation-adjusted) gain. We keep this calculator's rate closer to the historical NGX compound annual growth rate so the projection reflects real market behaviour rather than an optimistic guess.
A more realistic example: investing ₦50,000 per month for 12 years at an assumed 11% annual return grows to approximately ₦14,977,751, against total contributions of ₦7,200,000 — a gain of about ₦7.78 million. This still assumes returns stay positive and inflation cooperates, which history shows is not guaranteed.
Frequently Asked Questions
How does a monthly investment work in Nigeria?
You invest a fixed amount each month into funds or an index. You buy more units when prices are low and fewer when high (cost averaging), and returns compound over time.
What return can I expect in Nigeria?
Long-term historical equity returns are around 11% per year here, though any single year can be sharply up or down. NGX All-Share long-term ≈ 15–20% (nominal, NGN). Many investors use USD funds via Cowrywise, Bamboo to hedge inflation.
How much do I need to start investing in Nigeria?
Most platforms let you start small and increase later. Setting up an automatic monthly investment builds discipline and smooths out market timing.
Should I invest a lump sum or monthly in Nigeria?
Investing monthly spreads your entry across market ups and downs (cost averaging) and is easier to budget. A lump sum can do better in a steadily rising market but carries more timing risk.
Is investing better than a fixed deposit in Nigeria?
Investing targets higher long-term growth but carries market risk; fixed deposits are safer but usually return less. Many people hold both, matched to their time horizon.
Is an 18% annual return realistic for Nigerian equity investments?
Not consistently. Long-run NGX data points to a compound annual growth rate closer to 10–11% over the 2014–2023 period, even though some individual years (like 2024 and 2025) far exceeded 18% due to naira devaluation and inflation. Treat 18% as an optimistic, not a base-case, assumption.
Why do Nigerian nominal returns look so high if inflation is a problem?
Because a large share of nominal stock market and interest-rate gains in Nigeria simply keeps pace with rising prices and a weakening naira rather than reflecting real (inflation-adjusted) wealth growth. With Treasury Bill yields around 17.34% and inflation around 15.39% (2026 data), the real return on even 'safe' instruments has often been thin.
Should I use a higher or lower rate than the site default?
Use a range. Run this calculator at a conservative rate (around 8–10%), a moderate rate (around 11–13%, close to the historical NGX compound annual growth rate), and an optimistic rate (16–18%) to see how sensitive your projected outcome is to the return assumption.
