Should I invest a lump sum or use DCA?

If you can handle short-term volatility and are investing for 5+ years, lump sum statistically wins most of the time. If you'd lie awake worrying about a market crash the day after investing, DCA provides peace of mind. The best strategy is the one you'll actually follow through with.

How often should I invest with DCA?

Monthly is most common and practical (aligns with salary). Weekly or fortnightly also works but incurs more brokerage costs. Less frequent than monthly (e.g., quarterly) may be too slow to deploy your capital. Over 12 months is the sweet spot for most people.

Does DCA work for crypto?

DCA is actually MORE useful for highly volatile assets like crypto, where timing the market is nearly impossible. By investing a fixed amount regularly, you smooth out the extreme price swings. However, only invest in crypto what you can afford to lose entirely.

Dollar cost averaging (DCA) means investing a fixed amount at regular intervals, regardless of market price. It's the opposite of trying to 'time the market.' While academic research shows lump sum investing beats DCA about two-thirds of the time (because markets trend upward), DCA provides crucial psychological benefits — it removes the fear of investing at the 'wrong' time. This calculator compares both strategies so you can choose what works for your risk tolerance.

Real-World Examples

Lump Sum Wins in Rising Market

Alice receives $100,000 inheritance. She invests it all at once vs DCA over 12 months in a market that rises 10%.

Lump sum: $110,000 after 12 months. DCA: ~$105,000 (because she drip-fed money while the market rose). In a consistently rising market, getting invested ASAP wins.

DCA Wins in Volatile Market

Same $100,000, but the market drops 15% in the first 6 months then recovers to even by month 12.

Lump sum: $100,000 (break even). DCA: ~$106,000 — because she bought more units at lower prices during the dip, her average purchase price was lower.

Glossary

An investment strategy where you invest a fixed dollar amount at regular intervals, regardless of the current price. You buy more units when prices are low and fewer when prices are high.

Lump Sum Investing

Investing all available capital at once rather than spreading it over time. Historically produces higher returns but with more short-term volatility risk.

Average Cost Basis

The average purchase price of your investments when bought at different prices over time. DCA typically results in a lower average cost basis in volatile markets.
