See what that purchase actually costs you — every dollar you spend is a dollar that stops compounding. The Real Price Tag shows you the *real* cost of any online purchase — not the sticker price, but the future you give up by spending instead of investing. When you land on a product page or open your cart, a small badge appears in the corner showing what that money would be worth in a few decades if you invested it instead. Click for the full breakdown. What it shows • Sticker price vs. compounded future value at your assumed return rate • How much growth you forfeit by buying now • Optional: hours of your life the purchase represents at your wage Where it works • Amazon product pages and cart/checkout • Shopify, Target, Best Buy, Walmart, and most major retailers • Any site that publishes price data via JSON-LD Product schema or Open Graph product meta tags Settings • Adjustable annual return rate (default 10% — S&P 500 historical average) • Adjustable time horizon (1–40 years) • Optional salary or hourly wage input Privacy • 100% local — no data leaves your device • No analytics, no tracking, no account • Your settings sync via Chrome's standard storage API; we never see them Not financial advice — just math, to make you think twice.
