Inflation Calculator
SvelteKit / Tailwind / TypeScript
Description
A fast CPI-based calculator for seeing how much income needs to change over time to maintain purchasing power, especially as inflation and housing costs keep climbing.
Overview
The applet is intentionally simple and focuses on one question: what income in one year is equivalent purchasing power in another. It uses US CPI year-over-year data from 1918 to 2025. Since housing often rises faster than CPI in many markets, this can still understate real-world affordability pressure.
