Across kiosks and open markets in Lagos, sachet products have added quietly a dimension on how inflation is experienced. The price on the pack may look unchanged; ₦50, ₦100, ₦200, but the quantity inside is shrinking. This is shrinkflation in its most visible and most consequential form.
Why Nigeria’s Sachets are Shrinking
Nigeria’s inflation story provides the backdrop. According to the National Bureau of Statistics, Nigeria has experienced soaring inflation in the past 6 years with headline hitting 34.19% in June 2024; a situation that has recently eased to 15.06% in February 2026. Food inflation which is more relevant to sachet consumption has consistently tracked higher over the past two years.
But input costs have risen much faster than consumer prices suggest:
- The naira has depreciated by over 60% between 2023 and 2025, increasing the cost of imported raw materials (milk powder, chemicals, packaging inputs).
- Diesel prices, critical for manufacturing and logistics have risen by 200–300% since 2022, depending on region.
- Packaging costs (especially flexible plastics used in sachets) have increased by 30–50%, driven by FX pressures and global resin prices.
Faced with these pressures, FMCG companies have adjusted in less visible ways. Industry tracking shows sachet sizes in categories like milk, detergents, and beverages have reduced by 10–25% on average over the last 18–24 months. In some extreme cases, effective quantity reductions are close to 30%, while nominal prices remained unchanged.
Why Sachets Absorb the Shock First
Sachet products dominate Nigeria’s FMCG volume. Estimates suggest that over 60–70% of fast-moving consumer goods are sold in small units, largely sachets and single-use packs.
This makes them the most efficient lever for managing inflation shocks. A ₦100 sachet reduced by 20% in size effectively increases the unit price by the same margin without triggering immediate consumer resistance.
For a consumer earning daily income, maintaining the ₦100 price point is more important than the actual grams inside.
The Real Price Nigerians Are Paying
Shrinkflation shifts the burden disproportionately. 1) A 20% reduction in quantity means consumers are paying 20–30% more per gram or milliliter, even if the shelf price is unchanged, and 2) Low-income households who rely on sachets for daily consumption now face higher effective inflation than official CPI figures capture.
For example, a detergent sachet that once handled 3 washes now deliver 2. A cup of tea that once required one sachet of milk now require 2. This has translated into more frequent purchases and a higher cumulative monthly spending.
Corporate Strategy: Protecting Volume, Not Value
For manufacturers, the numbers are clear: while passing full cost increases to consumers risks volume decline of 15–25% in price-sensitive segments, shrinking pack sizes allows companies to preserve sales volume and market share, even as margins remain under pressure.

This is why shrinkflation is more prevalent in sachets than in larger pack formats, where consumers are more price-aware and can compare value per unit.
BuyerMetrics Insight: A Distorted Inflation Signal
Nigeria’s official inflation metrics do not fully capture shrinkflation dynamics. While CPI tracks price changes, it often misses quantity adjustments within the same price band. This creates a distortion; inflation is officially reported at 15%, but experienced inflation for sachet consumers is often at 20–35% in real terms, when quantity reduction is factored in
BuyerMetrics Bottom Line
Sachet products have become the frontline of Nigeria’s inflation crisis, not because prices are rising fastest, but because value is shrinking fastest.
In a market where over two-thirds of consumption happens in micro-units, shrinkflation is effectively a silent tax on the poor. The next competitive battleground will not just be affordability, but transparency: brands that can prove “more for your money” in measurable terms will capture trust in an economy where every gram now carries a price.
