What drove it
Each category’s weight multiplied by its price change. The eight add up to your estimate.
What this is, and is not
An estimate built from your own spending mix and the eight published CPI expenditure groups. It is not an official measure of your cost of living: within each group your actual purchases differ from the national basket. Comparisons cannot start before January 1993 — two of the eight categories were introduced in the 1998 revision of the CPI and are published back to then, no further.
