FatDCA: What if I invested it?

See what the price on any page would be worth invested, explain investing words on a page, and get a gentle buy-day reminder.

Before you buy, see what that money could have become. FatDCA is a free "what if I invested it?" calculator that lives in your browser. Click the icon on any product page and it shows what that price, invested in the S&P 500, gold or Bitcoin 10, 20 or 30 years ago, would be worth today, using real historical prices. It's the opportunity cost of every purchase, in one click. WHAT IT DOES Invest it: finds the price on the page (or the price you select) and shows it invested 10, 20 and 30 years ago, plus the same amount as a monthly habit (dollar-cost averaging) for 10 years. Hours of work: add your hourly pay and every price also shows as the hours you'd work to pay for it. Today: an "on this day" fact from market history, with what $1,000 invested then is worth now, and a daily quote on saving, investing and building wealth. Words: every investing term on the page, like ETF, index fund, Roth IRA, 401(k), expense ratio or compound interest, explained in one plain line. Skipped: tap "I skipped it" when you don't buy something and keep a private tally of what that money could grow to. Buy-day reminder: an optional weekly or monthly nudge with a small chart of your own investing plan. Shortcuts: right-click any price and choose "What if I invested…", or type "fatdca 129" in the address bar. Save a share image of any result. PRIVATE BY DESIGN No account, no ads, no tracking. FatDCA reads a page only when you click its icon, on your own computer. Your settings and skipped purchases stay on your device. The only thing it downloads is a public price file from fatdca.com. REAL DATA Monthly S&P 500 prices with dividends reinvested, gold and Bitcoin, from the same data behind the free calculators at fatdca.com, updated twice a month. Educational only, not investment advice. Past returns do not predict future returns.
