Dollar cost averaging is a simple yet effective investment strategy that can help you achieve long-term financial success. By investing a fixed amount of money at regular intervals, you'll be able to smooth out market fluctuations and reduce the impact of volatility.

Investing a fixed amount of money at regular intervals allows you to buy more shares when prices are low and fewer shares when prices are high. This can help you reduce the average cost of your investments over time.

The key to mastering the dollar cost averaging formula is to be consistent and patient. By investing regularly, you'll be able to ride out market ups and downs and stay on track with your long-term financial goals.

What is Dollar Cost Averaging?

Dollar-cost averaging is a simple yet effective way to invest, where you invest a fixed dollar amount on a regular basis, regardless of the share price.

This strategy helps you develop a disciplined investing habit and can potentially lower your stress level. It's a great way to be more efficient in how you invest.

By investing a fixed amount regularly, you'll buy fewer shares when the market is up, but more shares when it's down. This can lower your average cost per share over time.

Investing $100 every month is a great example of dollar-cost averaging in action. It's a manageable amount that can help you build a habit of investing.

Benefits and Advantages

Dollar-cost averaging is a smart way to invest in the stock market. It helps you develop good investing habits by setting up regular, automatic contributions, making it less likely to miss the money you invest.

By investing the same amount on a regular schedule, you can minimize your risk and take the anxiety out of the equation. This strategy allows you to buy more shares when prices are low and fewer shares when prices are high, helping to average out your purchase prices.

Dollar-cost averaging is a straightforward investment strategy that doesn't require constant monitoring or complex decision-making. This makes it a great option for new investors or those who simply have no time or desire to watch the market.

Here are some of the key benefits of dollar-cost averaging:

  • Establishes good investing habits and helps you stick to your plan
  • Keeps you open to opportunities and prevents you from missing the rebound
  • Prevents you from chasing "hot stocks" and getting overconfident
  • Minimizes your risk and takes anxiety out of the equation
  • Averages out purchase prices and simplifies investing

Best Method

The best method for implementing dollar-cost averaging is to set up a consistent schedule, like weekly, every other week, or monthly. This allows you to spread out your investments and reduce the impact of short-term market fluctuations.

By investing regularly, regardless of market conditions, you'll be less likely to miss out on opportunities and more likely to stick to your plan. As Warren Buffett once said, "When we bought anything, we always hoped it would go down for a while so we could buy more."

You can determine how much you can comfortably afford to invest and decide how often you'll invest. Your schedule could be weekly, monthly, or whatever makes sense for you. It's essential to automate your investments to simplify the process and remove the temptation to spend the money or panic buy or sell.

A dollar-cost averaging strategy enabled a hypothetical investor to take advantage of a price decline in Month 3, significantly reducing the average cost per share. Despite paying $4 or more per share in four out of the five months, the average cost per share came out to $3.70, and the investor was able to purchase a total of 135 shares.

Cautions and Considerations

You should set the growth factor at 0% if your contribution amount is not expected to grow, so that investment growth is the only growth variable. This ensures that value averaging focuses solely on investment growth.

Value averaging may require both purchases and sales of the underlying investment, based on investment performance. This means you'll need a cash account for prospective purchases as well as any sales proceeds.

Be careful in a declining market, as you'll need to have additional funds available for investment. This can be a challenge, especially if the market is volatile near the end of your investing time frame.

To avoid realizing taxable capital gains, consider restricting value averaging to tax-advantaged accounts or adopting a policy constraint that forbids or delays sales in the taxable account.

Here are some key considerations to keep in mind:

  • Additional funds may be needed for investment in a declining market.
  • Value averaging sales can realize taxable capital gains.
  • Consider using tax-advantaged accounts or policy constraints to minimize tax implications.

Cautions and Considerations

Value averaging can be a complex strategy, and it's essential to understand its limitations. If your contribution amount is not expected to grow, you should set the growth factor to 0% to ensure investment growth is the only growth variable.

Value averaging may require both purchases and sales of the underlying investment, which can result in taxable capital gains. This is especially true if you're not using tax-advantaged accounts.

To avoid realizing taxable capital gains, consider adopting a policy constraint that restricts or delays sales in your taxable account. This can help minimize tax liabilities.

In a declining market, you'll need to have additional funds available for investment. As your account value grows, you may need even more funds to reach the chosen investment period, which can be a significant challenge.

Here are some key considerations to keep in mind:

Reverse

Reverse dollar cost averaging can actually hurt your returns, especially in retirement. Henry K. Hebeler calls this process "reverse dollar cost averaging", and it's the opposite of what you'd expect.

When you're saving for retirement, you're buying more shares when prices are low and less when prices are high. But during retirement, you're redeeming more shares when prices are low and less when prices are high, which can reduce your expected returns.

The results are stark, with average real returns of 2.6% for a portfolio that's being distributed during retirement, compared to 3.2% for an accumulating investor who's saving for retirement.

Here are the average real returns for a portfolio with 50% large cap stocks, 40% long-term corporate bonds, and 10% treasury bills, over 20-year rolling periods from 1927 to 1995:

Minimizing Regret

Minimizing regret is a crucial aspect of investing, and dollar-cost averaging can help prevent emotional decision-making. By investing smaller sums of money over time, you're less likely to feel regret if a trade turns out to be poorly timed.

Most people are inherently loss-averse, reacting more strongly to losses than gains. This can lead to poor investment decisions, but dollar-cost averaging can help mitigate this bias.

Investors often cling to a single price anchor, refusing to sell an investment bought at a historical high. By dollar-cost averaging into a position, you may be less likely to hold onto a losing investment.

Costs

Investing in mutual funds or ETFs can come with hidden costs that might surprise you. Most no-load mutual funds have no fees for small, regular investments.

However, many investors still pay a commission to purchase a load-fund or an ETF. This commission can be a significant expense, especially if you're investing a large amount.

Dollar cost averaging, a popular investment strategy, can sometimes be more expensive than investing a lump sum. This is particularly true when buying a load-fund or an ETF, where the commission can eat into your returns.

The bid/ask spread for ETFs is the same whether you're using dollar cost averaging or investing a lump sum. This means you can't avoid the spread by choosing one method over the other.

Setting Up and Managing Investments

To set up dollar-cost averaging, start by determining how much you can afford to invest each month. Decide on a schedule that works for you, such as weekly or monthly investments.

You'll also need to choose where to invest your money. Consider your long-term goals and risk tolerance when deciding between stocks, index, exchange-traded, or mutual funds.

Automating your investments is key to simplifying the process and removing the temptation to spend or make impulsive decisions. Navy Federal members can set up automatic transfers from their checking or savings accounts to their investment accounts.

Investing regularly, regardless of market conditions, is the best approach with dollar-cost averaging. Aim to invest on a consistent schedule, such as every 2 weeks or monthly, to spread out your investments and reduce the impact of short-term market fluctuations.

Here are some common investment schedules to consider:

Remember to review your portfolio regularly and make adjustments as needed. Life changes, such as marriage or a change in employment, may require adjustments to your investment strategy.

Lump Sum vs. Dollar Cost Averaging

Lump sum investing will always carry a higher expected return, because it immediately moves your funds from asset classes with lower expected returns to ones with higher expected returns.

A Vanguard study concluded that lump sum investing has historically produced higher returns two thirds of the time when the DCA plan was implemented over 12 months.

Dollar cost averaging is superior for investors who are willing to sacrifice some expected return in order to reduce their potential loss, knowing that higher expected return come with higher potential loss.

In such volatile markets, your actual return can be higher than the return of the lump sum which will match the return of the assets.

Most investors pay a commission to purchase a load-fund or an Exchange-traded fund (ETF), which could make dollar cost averaging into a load-fund or an ETF far more expensive than purchasing as a lump sum.

However, for ETFs, the bid/ask spread is the same between DCA and lump sum.

If a DCA plan was implemented over 36 months, lump sum investing produced higher returns approximately 92% of the time.

The maximum downside potential of DCA was higher than the maximum upside potential over a 12-month period.

Investment Resources and Tips

To set up a dollar-cost averaging strategy, you need to determine how much you can comfortably afford to invest, which could be weekly, monthly, or whatever schedule makes sense for you.

Decide how often you'll invest, whether it's weekly, monthly, or another frequency that fits your lifestyle.

Choose where you'll invest, considering your long-term goals and risk tolerance. Will you include stocks, index funds, exchange-traded funds, or a mix?

Automate your investments to simplify the process and avoid the temptation to spend the money or make impulsive decisions.

To automate your investments, you can set up automatic transfers from your checking or savings accounts to your investment accounts, like Navy Federal members can do.

You should review your portfolio regularly and make adjustments when necessary, and be prepared to change your strategy if your circumstances change, such as getting married or divorced, or adding a family member.
