Methodology & Grounding Evidence
On September 11, Watcher.Guru reported: "BREAKING: 🇺🇸 US inflation remains at 3.4%." This simulator applies standard compounding algorithms: Category Spend \(S_t = S_0 \times (1 + r)^t\). Effective basket inflation is calculated as the weighted sum of category inflation rates. Purchasing power loss reflects the diminished real value of original cash inflows: \(1 - (1 + r_{\text{effective}})^{-t}\). Cumulative extra expenditure sums annual expense inflation relative to baseline spend across the selected horizon.
