Frequently Asked Questions
What is dollar cost averaging (DCA)?▼
Dollar cost averaging is an investment strategy where you invest a fixed amount of money at regular intervals (e.g., $500 every month) regardless of whether the market is up or down. Over time, this means you buy more shares when prices are low and fewer when prices are high, averaging out your cost basis.
Is DCA better than lump sum investing?▼
Research shows lump sum investing outperforms DCA about 2/3 of the time because markets tend to go up over time. However, DCA reduces risk and emotional stress. It is especially beneficial for investors who receive income regularly, want to reduce timing risk, or feel uncomfortable investing a large sum all at once.
What is a realistic annual return rate to use?▼
The S&P 500 has historically returned about 10% annually before inflation (roughly 7% after inflation). For conservative estimates, use 6-7%. For moderate estimates, use 8-10%. Remember that actual returns vary significantly year to year.
How often should I invest with DCA?▼
The most common DCA frequency is monthly, often aligned with paychecks. Weekly or biweekly investing can provide slightly better averaging but the difference is usually minimal. The most important factor is consistency — choose a frequency you can maintain long-term.
Does DCA work with crypto and stocks?▼
Yes, DCA works with any investment asset including individual stocks, ETFs, index funds, and cryptocurrencies. It is particularly popular with volatile assets like crypto because it smooths out the effects of large price swings.
