Tesla (TSLA) DCA Calculator
What a fixed monthly buy of Tesla actually did — computed from real daily closes (Jun 2010 → 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 TSLA, 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 $104,791. 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 TSLA'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:
134 possible 5-year start months — 96% ended positive.
Why dollar-cost average into Tesla?
Tesla compresses a lifetime of volatility into fifteen years: a ~15x run into 2021, then a −73% drawdown into early 2023, then another violent recovery. For no other large stock does the start month decide as much — which is exactly what the timing-luck strip above quantifies. Monthly buys turn that chaos from a verdict on one entry into an average across all of them.
The caveat is that averaging cuts both ways on a story stock: the same schedule that bought the $110 lows also bought the euphoric tops, and Tesla's price still embeds expectations (robotaxis, energy, margins) that can re-rate violently in either direction. DCA manages your entry risk — it does not make the underlying bet smaller.
FAQ
History, not opinion: $100 every month into TSLA for the last 10 years (121 buys, $12,100 invested) would be worth $104,791 today — +766% 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 TSLA's history began Jun 2014 and finished at -30%. The best (Nov 2016) finished at +1425%. 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 TSLA'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.
