Social Benefits Indexation Calculator
Calculate estimated adjustments to social welfare and disability benefits based on regional legislation and indexation rules.
About
Social welfare benefits, including disability and unemployment support, are subject to periodic adjustments mandated by law. These adjustments are intended to align benefit levels with the cost of living, yet the formulas vary significantly by jurisdiction. This tool helps beneficiaries and social workers estimate upcoming changes to payments by applying the specific indexation rules of the US, UK, or Canada. Whether it is the "Triple Lock" in the UK or the COLA determination in the US, knowing your future income is essential for household budgeting.
This calculator automatically applies statutory caps, freezes (common during austerity measures), and percentage increases based on legislative history. It serves as a navigational aid through the complex bureaucracy of benefit indexation.
Formulas
For most indexation systems, the new benefit rate is calculated as:
Note: Some benefits have a "Benefit Cap" C, such that Bfinal = min(Bnew, C).
