Brunei inflation calculator 2026

Prices in Brunei Darussalam have moved slowly. The Department of Economy and Statistics (DEPS) publishes the Consumer Price Index every month, and the latest index is 106.2 for the month starting September 1, 2026.

Enter an amount and the month it comes from. You get its value in today's prices, the total change and the average change a year.

How it's calculated

The calculator divides the latest CPI, 106.2, by the CPI of the month you pick. That ratio is multiplied by your amount.
The total change is the ratio minus one. The yearly average spreads that change over the number of years between the two months.
The series starts in January 2021. Index values are those printed in the DEPS monthly table. December 2024 is left out because the figure on that table does not match its own year on year change.

An example

BND 1,000 from January 2021, when the index was 101.9, equals BND 1,042.20 now. That is a rise of 4.2 percent over five years and eight months. BND 1,000 from January 2025 equals BND 1,002.83.
