The NCPI is Tanzania's official measure of consumer price changes, compiled by the National Bureau of Statistics (NBS) and released monthly.
383 goods and services in total — comprising 132 food and non-alcoholic beverage items and 251 non-food items. Prices are collected from all 26 regional headquarters on the Tanzanian mainland.
Weights are derived from the 2017/18 Household Budget Survey, covering both urban and rural households across all 26 mainland regions. The base price reference period is January–December 2020 (index = 100).
The NCPI follows the UN COICOP 2018 framework, disseminated across 13 divisions. Supplementary indices include: Core, Non-Core, Energy/Fuel/Utilities, Services, Goods, Education, and All Items Less Food.
Elementary aggregates use the geometric mean of price relatives. Higher-level aggregates use the Lowe Index formula (a type of Laspeyres index), providing a consistent and internationally comparable measure.
The headline rate remained unchanged from February 2026, indicating stable overall price conditions. The overall NCPI climbed from 119.27 in March 2025 to 123.04 in March 2026.
