How Dollar-Cost Averaging Works

Dollar-cost averaging is a simple tool that an investor can use to build savings and wealth over the long term. It is also a way for an investor to ignore 𒁃short-term volatility in the broader markets.

A prime example of long-term dollar-cost averaging is its use in 澳洲幸运5官方开奖结果体彩网:401(k) plans, in which employees invest regularly regardl෴ess of the price of th🐼e investment.

With a 401(k) plan, employees can choose the amount they wish to contribute as well as the investments offered by the plan in which to invest. Then, investments are made automatically every pay period. Depending on the markets, employees might see a larger or smaller number of sec🃏urities added to their accounts.

Dollar-cost averaging can also be used outside of 401(k) plans. For instance, investors can use it to make regular purchases of mutual or 澳洲幸运5官方开奖结果体彩网:index funds, whether in another tax-advantaged account such as a traditional individual retirement accou൩nt (IRA) or a taxable brokerage accou💦nt.

Dollar-cost averaging is one of the 澳洲幸运5官方开奖结果体彩网:best strategies for beginnꦯ🍷ing investors looking to trade exchange-traded funds (ETFs). Additionally, many 澳洲幸运5官方开奖结果体彩网:dividend r💟einvestment plans (DRIPs) allow investors to doꦡllar-cost average by making purchases regularly🌠.

Benefits of Dollar-Cost Averaging

  • It can lower the average amount you spend on investments.
  • It reinforces the practice of investing regularly to build wealth over time.
  • It’s automatic and can take concerns about when to invest out of your hands.
  • It removes the pitfalls of market timing, such as buying only when prices have already risen.
  • It can ensure that you’re already in the market and ready to buy when events send prices higher.
  • It takes emotion out of your investing and prevents you from potentially damaging your 澳洲幸运5官方开奖结果体彩网:portfolio’s returns.

Who Should Use Dollar-Cost Averaging?

The investment strategy of dollar-cost averaging can be used by any investor who wants to take advantage of its benefits. These include a potentially lower average cost, automatic investing over regular intervals of time, and a meth💎od that relieves investors of the stress of having to make purchase decisions under pressure when the market is volatile.

Dollar⛦-cost averaging may be especially useful to beginning investors who don’t yet have the experience or expertise to judge the most opportune moments to buy.

It can also be a reliable strategy for long-term investors who are committed to investing regularly but don't have the time or inclination to watch the market and time their orders.

However, dollar-cost averaging isn’t for everyone. It isn’t necessarily appropriate for those investing in time periods when prices are trending steadily in one direction or the other. Be sure to consider ✅your outlook for an investment, plus the broader market, when deciding to use dollar-cost averaging.

Special Considerations

It’s important to note that dollar-cost averaging works well as a method of buying an investment over a specific period of time when the price fluctuates up and ꦕdown. If the price rises continuously, those using dollar-cost averaging end up buying fewer shares. If it declines c⛦ontinuously, they may continue buying when they should be on the sidelines.

So, the strategy can’t protect investors against the risk of declining🌼♉ market prices. Like the outlook of many long-term investors, the strategy assumes that prices, though they may drop at times, will ultimately rise.

Using this strategy to buy an individual stock without researching a company’s details could prove detrimental as well. That’s because an investor might continue to buy more stock when they o𒁏therwise would stop buying or exit the position.

For less-informed investors, the strategy is far less risky when use🌌d to buy index funds rather than individual stocks.

Investors who use a dollar-cost averaging strategy will generally lower their 澳洲幸运5官方开奖结果体彩网:cost basis in an investment over time. The lower cost basis will lead to less of a loss on investments that decline in price and generate greater gains on investments t꧋hat increase in price.

Example of Dollar-Cost Averaging

Joe works at ABC Corp. and has a 401(k) planཧ. He receives a paycheck of $1,000 every two weeks. Joe decides to allocate 10% or $100 of his pay t🌄o his employer’s plan every pay period.

He chooses to contribute 50% of his allocation to a large-cap mutual fund and 50% to an 澳洲幸运5官方开奖结果体彩网:S&P 500 index fund. Every two weeks, 10%, or $100, of Joe’s pretax pꦚay will buy $50 worth of each of𒐪 these two funds, regardless of the fund’s price.

The table below shows half of Joe’s $100 contributions that went to the S&P 500 index fund over 10 pay periods. Throughout 10 paychecks, Joe invested a total of $500, or $50 per week. The price of the fund incꦐreased and decreased over that time.

The results of dollar-cost averaging:

Joe spen♒t $500 in total over the 10 pay periods and bought 47.71 shares.

He paid an averag♔e price of $10.48 ($500/47.71).

Joe bought different share amounts as the index fund increased and dec♕reased in value due to market fluctuations.

The results if Joe spent one lump sum:

Say 🦂that, instead of using dollar-cost averaging, Joe spent his $500 at one time in pay period 4. He paid $11 per share.

That would have resulted i꧂n a purchase of 45.45 shares ($500/$11).

There was no way for Joe to know the best time to buy. By using dollar-cost averaging, though, he was able to take advantage of several price drops despite the fact that the s✱hare price increased to over🌳 $11. He ended up with more shares (47.71) at a lower average price ($10.48).

How Will I Use This in Real Life?

If you have a stock you’d like to invest in but aren’t clear on when the best time to buy is, dollar-cost averaging (DCA) can help. By following a simple routine of automatic stock purchases, whether weekly, biweekly, or monthly, DCA allows you to invest consistently without needing to analyze the market or wait for a dip (which can be difficult to predict). This is partic⛎ularly helpful if you’re new to investing.

You can use DCA to purchase individual shares and ETFs or to make regular contributions to your IRA. The strategy is to choose a fixed amount you’re comfortable with and stick with it, regardless of how the market is performing. This helps average out the cost of your investments over time while simultaneously removing the emotional aspects of investing, allowing you to build your portfolio steadily.

Is Dollar-Cost Averaging a Good Idea?

It can be. When dollar-cost averaging, you invest the same amount at regular intervals and by doing so, hopefully lower your average purchase price. You will already be in the market when prices drop and when they rise. For instance, you’ll have exposure to dips when they happen and don’t have to try to time them. By investing a f♈ixed amount regularly, you will end up buying more shares when the price is lower than when it is ♌higher.

Why Do Some Investors Use Dollar-Cost Averaging?

The key advantage of dollar-cost averaging is that it reduces the negative effects of 澳洲幸运5官方开奖结果体彩网:investor psychology and market timing on a portfolio. By committing to a dollar-cost averaging approach, investor🍌s avoid the risk that they will make counterproductive decisions out of greed or fear, such as buying more when prices are rising or panic selling when prices decline. Instead, dollar-cost averaging forces inve⛄stors to focus on contributing a set amount of money each period while ignoring the price of the target security.

How Often Should You Invest With Dollar-Cost Averaging?

With regard to actually using the strategy, how often you use it may depend on your 澳洲幸运5官方开奖结果体彩网:investment horizon, outlook on the market, and experience with investing. If your outlook is for a market in flux that will eventually rise, then you might try it. If 𒅌a persistent bear market is at work, then it wouldn’t be a smart strategy to use. If you’re planning to use it for long-term investing and wonder what interval for buying makes sense, consider applying some of every paycheck to the regular purchases.

The Bottom Line

Dollar-cost averaging (DCA) is a simple and straightforward way of investing that reduces the emotional stress of trying to invest at the right time. By sticking to a fixed investment schedule and amount, you naturally buy more shares when the price ⛄isꦡ low vs. high.

DCA may not be the most perfect investment strategy, as it doesn’t protect against market risk. However, it allows investors to stick with regular investing, build up a portfolio over time, and decrease the anxiety of trying to time the market.
