Why the fee field defaults to 1.5%
Because in Nigeria your real cost per leg is the P2P spread, not the exchange's trading fee.
A Nigerian-friendly exchange charges 0.1% to 0.25% to trade. A P2P merchant takes 1% to 3%. If you buy and sell through P2P — which most Nigerian users do — your round-trip cost is realistically 2% to 6%, not the 0.2% to 0.5% the exchange advertises. Setting the field to 1.5% per leg gives you an honest picture. Set it to 0.2% only if you are genuinely trading an order book on both sides.
Watch the break-even row. It is the most useful number here and the one people never calculate. At a ₦1,520 entry with 1.5% per leg, you do not break even at ₦1,520 — you need roughly ₦1,566 before you have made a single naira. Anything between those two prices is a loss that looks like a gain.
Three Nigerian scenarios
1. The stablecoin ladder
You bought 600 USDT at ₦1,520 and the naira has moved to ₦1,690. Enter those figures with 1.5% per leg: a gross move of about 11.2% becomes roughly 8% net. Real, meaningful, and 3 percentage points smaller than the headline. This is the trade most Nigerian savers are actually making — see stablecoins in Nigeria.
2. The volatile position
You put ₦200,000 into an altcoin at ₦45 per token. Leave quantity at 0 and enter ₦200,000 as naira invested. The calculator derives 4,444 tokens. Now try a sell price of ₦60 and then ₦30 — the loss case is not symmetric with the gain case once fees are on both legs, which is exactly the asymmetry that makes frequent trading of volatile assets so unrewarding.
3. Whether to sell at all
Enter your holding, then use the live price button. If the net figure is positive, remember it is also a taxable disposal — a gain on paper becomes a gain plus a tax event the moment you act on it. That does not mean do not sell. It means the number to compare against your alternatives is the after-tax one.
What this calculator does not do
- Multiple purchases at different prices. For a pooled cost base across several buys, work out the average yourself — the method is set out in crypto tax in Nigeria.
- Tax. It gives you the gross gain. The tax treatment depends on your circumstances.
- Network fees. Add them into the fee percentage if you moved coins on-chain, or treat them separately — they are usually small but not always, on the wrong network.
- Leverage or funding costs. This is a spot calculator. If you are paying funding on a perpetual, this understates your cost substantially.
How this tool gets its numbers
crypto.net.ng serves static pages — there is no server doing calculations for you. This tool reads a public market-data API directly from your browser and renders the result on your device. Three consequences worth knowing:
- Nothing you type is sent to us. Amounts you enter stay in your browser.
- An ad-blocker or a network block can stop it. If the numbers do not appear, that is usually why. The page tells you rather than showing a blank space.
- A market reference rate is not a P2P quote. This is the single most important thing to understand about any naira crypto tool — see Nigerian P2P rates for why the two differ and by how much.
Frequently asked questions
How do I calculate crypto profit in naira?
Net profit equals (sell price × quantity) − (buy price × quantity) − all fees on both legs. The calculator above does it, and importantly it also gives you the break-even sell price, which is higher than your buy price once fees are included.
What fee percentage should I use for Nigeria?
Use 1–2% per leg if you trade P2P, which most Nigerian users do — that is the merchant spread, and it dwarfs the exchange's 0.1–0.25% trading fee. Only use 0.2% if you are genuinely trading an order book on both sides.
What is a break-even price?
The sell price at which you have recovered your cost plus all fees — the point where you stop losing money rather than the point where you start making it. It is always above your buy price, and most people never work it out.
Does this calculator account for tax?
No. It gives you the gross gain. Following Nigeria's 2025 tax reform, a disposal at a gain is a taxable event from January 2026, so compare after-tax outcomes when deciding whether to sell.
Can I calculate profit across several purchases at different prices?
Not directly. Work out your average cost across all purchases first — total naira paid divided by total quantity — then enter that average as the buy price.
