Amazon (AMZN) DCA Calculator
What a fixed monthly buy of Amazon actually did — computed from real daily closes (May 1997 → Jul 2026), not projections. Run your own amount and schedule below.
What $100 a month actually built
The last 10 years of a $100 monthly plan in AMZN, month by month: the flat line is cash paid in ($12,100 total), the accent line is what the position was worth along the way — ending at $30,125. Every point is computed from that day's real close.
Timing luck, quantified
Same plan, different start month. Each bar below is one possible 5-year monthly DCA window in AMZN's history, sorted from worst to best — the honest spread between unlucky and lucky timing, and the case for starting on a schedule instead of waiting:
291 possible 5-year start months — 97% ended positive.
Why dollar-cost average into Amazon?
Amazon is the canonical patience story in our data: from the 1999 peak the stock fell roughly 94%, and it still ended up one of the great compounders of the era. Almost nobody held a 2000 lump sum through that crater. A monthly plan had a structural advantage — its heaviest accumulation happened at single-digit prices no one would have dared to time.
The 2022 rerun (about −56%) shows the pattern at smaller scale. What the chart cannot show is the fork where it goes the other way: plenty of 1999 e-commerce names fell 94% and never came back. The schedule earns you the average of a survivor's path — choosing a survivor remains your risk.
FAQ
History, not opinion: $100 every month into AMZN for the last 10 years (121 buys, $12,100 invested) would be worth $30,125 today — +149% before fees and taxes. Past performance doesn't predict the future, but that's what the plan actually produced.
The worst 5-year monthly-DCA start in AMZN's history began Jan 2018 and finished at -21%. The best (Sep 2013) finished at +276%. DCA doesn't delete timing luck — it narrows it and removes the decision.
A lump sum bets everything on one entry price. Monthly DCA spreads your cost across AMZN's ups and downs — you buy more units when it's cheap, fewer when it's expensive. Compare both directly in our lump sum vs DCA calculator.
