Dollar Cost Averaging Calculator

See how regular monthly investments grow over time. Enter your numbers and watch compound growth work its magic.

How DCA Works: You invest $500 every month, rain or shine. When prices are low, your $500 buys more shares. When high, it buys fewer. Over time, your average cost per share tends to be lower than the average price — that's the DCA advantage.

FAQ

What is dollar cost averaging?

DCA is investing a fixed amount at regular intervals, regardless of price. It reduces volatility impact by buying more shares when prices are low.

Is DCA better than lump sum?

Lump sum beats DCA about 66% of the time historically. But DCA reduces regret and is easier for beginners. The best approach is the one you'll stick with.

How often should I invest?

Monthly is most common (aligned with paychecks). Bi-weekly or weekly also works. Consistency matters more than frequency.

What return rate should I use?

S&P 500 has averaged ~10% annually since 1926. For diversified portfolios, 7-10% is reasonable. Conservative: 5-7%.
