Most comparisons of Nigerian broker costs show only the headline commission rate. That is not enough. The real cost of an NGX trade has three components — and the part most people ignore (the SEC levy) is fixed at 0.3% regardless of which broker you use. Understanding total cost changes the decision.
Key finding: On a typical NGX trade, the broker commission is usually the largest variable cost but the SEC levy (0.3%) and CSCS fee apply at every broker equally. CardinalStone has the lowest stated commission rate (1.20%) of any tracked broker. For most trade sizes, the difference between the cheapest and most expensive broker on this list is under ₦3,000 per ₦100,000 traded.
The total cost of a ₦100,000 NGX trade at a 1.35% commission broker is approximately ₦1,650 — ₦1,350 broker commission plus ₦300 SEC levy. At CardinalStone's 1.20% rate, the total drops to about ₦1,500. The difference is real but modest for most trade sizes.

Total cost = broker commission + 0.3% SEC levy. CSCS fee not included as it varies by broker and trade size. Use this as a directional comparison, not an exact quote.
CardinalStone has the lowest stated commission of any tracked broker at 1.20% — 15 basis points below the 1.35% common among digital-first platforms. The tradeoff: the minimum account is ₦50,000, making it unsuitable for investors just starting out. Best for investors with ₦100,000+ who are already past the beginner stage and want to reduce long-term trading costs.
The difference between a 1.20% and 1.35% commission looks small per trade. Over time, across larger positions, it accumulates. Here is how the total cost scales:
| Trade size | CardinalStone (1.20%) | Mid-tier (1.35%) | Higher tier (1.59%) | SEC levy (all) |
|---|---|---|---|---|
| ₦50,000 | ₦600 | ₦675 | ₦795 | ₦150 |
| ₦100,000 | ₦1,200 | ₦1,350 | ₦1,590 | ₦300 |
| ₦250,000 | ₦3,000 | ₦3,375 | ₦3,975 | ₦750 |
| ₦500,000 | ₦6,000 | ₦6,750 | ₦7,950 | ₦1,500 |
| ₦1,000,000 | ₦12,000 | ₦13,500 | ₦15,900 | ₦3,000 |
Broker commission only. Add the SEC levy column to each figure for the full cost. On a ₦1M trade, the gap between CardinalStone and a 1.59% broker is ₦3,900 — meaningful if you trade frequently, less so for long-term investors who make a handful of trades per year.
For many investors, "cheapest" means cheapest to get started — the lowest barrier to opening an account. Broker commission matters less when you are investing small amounts infrequently. Here are the lowest-minimum options:
| Broker | Minimum | Commission | Digital onboarding |
|---|---|---|---|
| Trove | ₦1,000 | ~1.35% | Yes, 24–48h |
| Chaka | ₦2,000 | ~1.35% | Yes, 24–48h |
| Bamboo | ₦5,000 | ~1.80% | Yes, 24–48h |
| Meristem | ₦10,000 | ~1.35% | Partial, 2–5 days |
| Afrinvest | ₦50,000 | ~1.48% | Partial |
| CardinalStone | ₦50,000 | 1.20% | Partial |
Trove's ₦1,000 minimum is the lowest of any tracked broker. However, the minimum to buy a single board lot of most NGX stocks is determined by the stock price, not the broker minimum. For example, buying 100 shares of a stock trading at ₦50 costs ₦5,000 before commission — so the effective investing minimum is set by the market, not the broker floor.
Cost should be one factor, not the only factor. Here are situations where a slightly more expensive broker might make more sense:
