Nigeria's Smartest Investment
Calculator
Calculate real returns on FGN Bonds, Treasury Bills, Fixed Deposits, Money Market Funds and more — with live CBN rates and the latest published DMO rates.
⚠Treasury Bill rates are auto-updated from the CBN data API. USD/NGN is a third-party market mid-rate, not the CBN official window. FGN Bond, fund and bank rates are from their last publication and manually verified. The “fetched” time above is when we last checked, not when each source published. Each rate shows its source and publication date below it. Verify with DMO/CBN before investing.

Why CheckInvestNg
Built for Nigerian Investors
Generic investment tools don't understand Nigerian instruments. We do.
Live & Verified Rate Data
Every calculator reads one source of truth, and each rate names its own. Treasury-bill and inflation rates update daily from the CBN data API. Money market and mutual fund yields come from the SEC weekly NAV table, and bank deposit rates from the CBN weekly deposit table. FGN bond coupons and the MPR come from the DMO and CBN and are stamped with the date checked. USD/NGN updates every 4 hours from a third-party foreign-exchange feed, not the CBN window.
₦ & $ Support
Calculate in Nigerian Naira or US Dollars. Conversion uses a third-party market mid-rate refreshed every 4 hours — not the CBN official window rate. Toggle currencies at any time.
Mathematically Verified
Every formula — from NTB discount pricing to FGN coupon schedules — is cross-checked against official DMO and CBN documentation.
