What we track
10 series with anchored historical reference points going back to 2020. Each anchor below is recoverable from a named public source — NBS, CBN, AbokiFX, PropertyPro, or the operator's own published tariff.
Methodology
Between anchored dates we linearly interpolate. That's an approximation — actual prices don't move in straight lines — but it's honest about what we know and what we're estimating. Today's value is read from the daily snapshot archive when available (started 2026-05-23) — so the calculator updates daily without manual anchor edits. Older anchors remain hand-curated from named sources.
- FX rates are parallel-market / market-rate equivalents (not official CBN window).
- Fuel uses the PPPRA cap pre-May 2023 and NBS bulletin averages thereafter.
- Cement uses Dangote's ex-factory price (the market-leader benchmark).
- Food uses NBS Selected Food Prices bulletin medians.
- Rent uses PropertyPro's half-yearly Lagos mainland averages.
- Where an anchor is missing for a year, we interpolate from the bracketing dates.
The inflation index, weekly.
When the cement, rice or USD line moves, the weekly digest leads with it — alongside what the official NBS CPI release said the same week.
