Bitcoin DCA Calculator

Dollar-cost averaging means buying a fixed dollar amount of Bitcoin on a regular schedule — weekly, bi-weekly, or monthly — regardless of what the price is doing. You don't try to time the market. You just buy consistently.

The math behind it is straightforward. When Bitcoin drops to $60,000, your $100 buys more satoshis. When it spikes to $100,000, you buy fewer. Over months and years, your average purchase price smooths out below the peaks. That's the whole strategy.

Backtesting across every 3-year window since 2013, a simple monthly DCA into Bitcoin has been profitable 100% of the time when held for at least 3 years. Even investors who started buying in December 2017 — the absolute top of that cycle — broke even by mid-2020 and were up over 400% by early 2024.

DCA works because it removes the two biggest investing mistakes: waiting for "the right time" (which never feels right) and panic-selling during crashes (when you should be buying more). It turns volatility from an enemy into an advantage.

In traditional markets, lump-sum investing beats DCA about 68% of the time because markets trend upward. Bitcoin is different. Its extreme volatility — routine 30-50% drawdowns even during bull markets — changes the calculus significantly.

Analysis of every possible entry point since 2013 shows that lump-sum Bitcoin purchases outperform DCA only when you happen to buy near cycle bottoms (late 2018, March 2020, November 2022). The problem is you can't identify bottoms in real time.

DCA protects you from the worst-case scenario: investing your entire savings at a cycle top. Someone who put $12,000 into BTC on December 17, 2017 saw their investment drop 84% within a year. Someone who DCA'd $1,000 monthly starting that same day accumulated more Bitcoin at a significantly lower average cost and recovered much faster.

The practical answer: if you have a lump sum and strong conviction, invest 50-70% immediately and DCA the rest over 3-6 months. If you're investing from income, straight monthly DCA is hard to beat. Use our Lump Sum vs DCA Calculator to compare both strategies with your actual numbers.

Backtested data from 2015-2024 reveals a persistent "Monday effect" in Bitcoin markets. Investors who consistently bought on Mondays accumulated approximately 14.36% more Bitcoin than those buying on Sundays, given the same total investment.

The pattern makes sense. Institutional selling pressure tends to be lightest over weekends, pushing prices slightly lower by Sunday night. Monday morning brings fresh buying from institutional desks and automated DCA services, driving prices up through the week. The effect is small on any given week but compounds over years.

That said, the best day to DCA is the day you can commit to consistently. Missing a Monday and buying Tuesday costs you almost nothing. Missing weeks because you're waiting for Monday costs you everything DCA is designed to provide: consistent exposure over time.

The table below shows what a $100/month DCA strategy would have returned based on the year you started. Every single starting year is profitable by 2026, but the earlier you began, the more dramatic the compounding.

Notice 2018 stands out. That was the worst year emotionally to be buying Bitcoin — prices cratered from $19,000 to $3,200. Yet disciplined DCA buyers in 2018 accumulated the most Bitcoin per dollar spent of any cohort in this table. The lesson: bear markets are when DCA shines hardest.

Most major exchanges offer automated recurring purchases. Set your amount, pick a frequency, connect a bank account, and walk away. The process takes under five minutes to configure.

Platforms like Swan Bitcoin, Strike, and River specialize in Bitcoin-only DCA with lower fees than general-purpose exchanges. Coinbase and Kraken also offer recurring buys, though their fee structures tend to be higher for small purchases.

For maximum security, withdraw to self-custody after each purchase or set a threshold (like 0.01 BTC) and transfer to a hardware wallet whenever you hit it. Leaving Bitcoin on an exchange defeats the purpose of accumulating a decentralized asset.

Track your average cost basis and total accumulation using our calculator above. Knowing your numbers keeps you motivated during bear markets and prevents emotional decisions. Many long-term holders check their DCA stats monthly and adjust contributions based on their budget — not based on price action.
