Your expenses in context. Your price trends in detail.
WertNoxX compares repeatedly recorded, comparable products. This reveals personal price trends independently of your total spending.
Your purchases are the benchmark
The personal price index and personal inflation are based on comparable recorded purchases. They describe your own data, not an official consumer price index.
Comparability matters
Repeat purchases, matching quantities and suitable periods are essential. The fewer comparable observations available, the more cautiously results should be interpreted.
Examine categories separately
Price-index analyses are available for groceries, personal care and household goods, pet supplies, tobacco, fuel and medication. This type of item price index is not used for contracts or one-off purchases.
Individual items are required
In the mode without AI, personal inflation, price indices and market comparisons are hidden. A store, date and total alone are insufficient for reliable item-price comparisons.
Your expenses in context. Your price trends in detail.
WertNoxX analyzes recorded prices over time. The personal price index adds a transparent trend to the view of individual purchases.
