Six purpose-built calculators for the decisions an NGX operator actually makes: sizing a trade, projecting compound growth, converting currencies at live rates, estimating CGT before a sale. No account needed.
Hold NGX positions already? Portfolio X-Ray reads your CSCS statement, broker screenshots, or a pasted list in seconds — value, top holdings, sector split. Underwater on a position? The recovery calculator does the break-even and DCA math. Weighing an FGN bond? The bond return calculator solves the yield, cashflows, and pull-to-par.
Project how a monthly DCA into NGX equities, T-bills, or MMFs compounds over 1–30 years. Year-by-year breakdown, exponential growth chart, shareable summary.
In 15 years, your ₦100.0K/month becomes ₦80.1M.

Risk-based sizing for a single equity trade. Inputs: account size, risk % per trade, entry, stop. Optional half-Kelly toggle if you have an edge estimate.
Total NGN you're sizing against. Cash + open positions.
Fraction of the account you're willing to lose if the stop hits.
Where you'll exit if the trade fails. Must be below entry for a long.
Gross + post-WHT income from a fixed sum across MMF / T-bill / equity instruments, with the canonical Nigerian withholding rules applied (CITA-exempt T-bills, 10% WHT on MMF / equity dividends).
The amount you have to invest.
Coupon, MMF yield, or trailing 12m dividend yield.
18.00% on ₦1,000,000 = ₦180,000 gross
10% deducted at source.
16.20% net yield on capital.
Cross-rates for NGN, USD, EUR, GBP, ZAR, KES, at the same FX rates the rest of the terminal uses. Type any amount in any currency; the others update instantly.
Tax on a single equity disposal under the Nigeria Tax Act 2025 — the ₦150M-proceeds / ₦10M-gains share exemption, then your income-tax band (or an honest range if you're not sure). A working draft for your accountant.
Total naira you paid, including original fees.
Gross naira received before exit fees.
Brokerage + NGX/CSCS + VAT on the sell ticket.
Chargeable gains are taxed at your personal income-tax rate (NTA 2025). Pick your top band, or leave 'Not sure' to see the range.
NTA 2025 exempts gains on Nigerian-company shares when your aggregate disposal proceeds stay under ₦150,000,000 AND your aggregate gains stay within ₦10,000,000 over 12 months. Enter your other realised proceeds and gains for this year so the check covers everything, not just this disposal.
Proceeds − cost − fees. 49.30% on cost basis.
Exempt — proceeds under ₦150M and gains within ₦10M (NTA 2025 share exemption).
What lands in your hand after tax settles.
Nigeria Tax Act 2025 rules (effective January 2026): the flat 10% CGT is repealed and chargeable gains are taxed at your personal income-tax band. Reinvesting the proceeds in Nigerian-company shares within the same year attracts proportional relief — not modelled here. A working draft for your accountant, not tax advice.
Estimator only. The canonical year-rollup (FIFO lot matching, carry-over basis chains, dividend WHT) lives at /tax/[year].
Backtest a holding mix against the last 1, 3, 6, or 12 months of NGX prices. Sector / single-stock concentration warnings included. Sign in to load your real portfolio.
