# What is a target-date fund, and should you use one?

> A target-date fund is an all-in-one mix of stocks and bonds that gets more cautious as its target year nears.

A target-date fund is one fund that holds a full mix of stocks and bonds and slowly shifts toward bonds as the year in its name gets closer. You pick the fund dated near the year you plan to retire, and it handles the mix and the rebalancing for you.

## Key facts
- **It is a fund of funds.** Most target-date funds own a handful of other funds, such as a US stock fund, an international stock fund and a bond fund. One purchase gives you all of them in a set mix.
- **The mix follows a glide path.** The glide path is the fund's schedule for moving from mostly stocks to more bonds as the target date nears. The fund's managers make those changes and rebalance for you.
- **Same year does not mean same fund.** Two funds with the same year can hold quite different mixes, follow different glide paths and charge different fees. Read the details of the one you are offered.
- **It can still lose money.** A target-date fund is invested in the markets, so its value rises and falls. It does not promise any amount of retirement income at or after its date.

## How a target-date fund works
Each fund in a family is named for a year, usually in 5-year steps. If you plan to retire in about 35 years, you choose the fund dated about 35 years from now. Everyone retiring around that time shares the same fund.
With decades to go, the fund holds mostly stocks, because stocks have more room to grow and you have time to ride out drops. As the date gets closer, the managers sell some stocks and buy bonds, which usually swing less. You don't have to place a single trade for any of this.

## The glide path, to or through
A "to" glide path reaches its most cautious mix at the target date and then stops changing. A "through" glide path keeps shifting for years after the date, so it holds more stocks at retirement and reaches its most cautious mix later.
Neither is right for everyone. A "to" fund is calmer near retirement. A "through" fund assumes you will keep drawing on the money for 20 or 30 years and need it to keep growing. Each fund's website shows its glide path as a chart.

## What target-date funds cost
Because the fund holds other funds, you may pay fees at two levels: the target-date fund's own fee and the fees of the funds inside it. The total shows in the prospectus fee table as one expense ratio.
Versions built from index funds often cost well under 0.20% a year. Versions built from actively managed funds can cost several times as much. On $20,000, 0.12% is $24 a year and 0.70% is $140. Same idea, same date, very different price.

## Who a target-date fund suits
It fits people who want a sensible mix without picking funds or rebalancing. That covers most new investors, and it is often the default in workplace plans for that reason.
It fits less well if you hold large investments elsewhere, like a spouse's 401(k) full of bonds, because the fund only manages itself and can't see your other accounts. It also fits less well if your comfort with risk is very different from a typical person your age. Then a different date, or your own mix of index funds, may suit you better.

## Picking a fund that fits
Start with the fund nearest your expected retirement year. Then check three things: the current stock and bond split, the total expense ratio and the glide path. If the mix looks too aggressive for you, choosing a fund with an earlier date makes it more cautious. A later date makes it bolder.
Once you choose, set your contributions to go into it automatically and leave it be. Checking once a year is enough.

## A worked example: Riley adds one fund too many
Riley, 30, has $12,000 in a target-date fund that holds 90% stocks and 10% bonds. To be safe, Riley also buys $8,000 of a US stock index fund in the same 401(k).

- Target-date fund: $12,000
- Bonds inside it (10%): −$1,200
- Stocks inside it (90%): = $10,800
- Separate stock fund: $8,000
- Total in stocks: = $18,800
- Stocks as a share of $20,000: 94%

1. Inside the target-date fund, $12,000 × 10% = $1,200 is bonds and $12,000 × 90% = $10,800 is stocks.
2. Adding the stock fund makes $10,800 + $8,000 = $18,800 in stocks out of $12,000 + $8,000 = $20,000.
3. $18,800 ÷ $20,000 = 94% stocks, more than the fund chose. The fund can't rebalance money it doesn't hold, so Riley moves the $8,000 into the target-date fund.

## Common mistakes
- **Mixing it with other funds by accident.** On a 401(k) menu it is easy to split money between a target-date fund and several other funds. It changes your mix in ways no one is watching. Hold it alone, or skip it and build your own mix.
- **Choosing by the year and nothing else.** Two funds with the same year can differ a lot in fees and in how much stock they hold. Spend five minutes on the fee table and the glide path.
- **Selling when the market drops.** A fund dated 30 years out is mostly stocks and will fall in a downturn. That is expected. Selling locks in the loss, and the fund is built to hold on.

## Questions people ask
### Are target-date funds a good idea?
For many people, yes, as long as the fee is low and it is the main fund in the account. They give a spread-out mix and rebalance automatically. They are less useful if you want to manage your own mix.

### Can I use a target-date fund in an IRA?
Yes. Target-date funds come as mutual funds and ETFs that you can hold in an IRA, a brokerage account or a 401(k). In an IRA, you can choose among many fund families and compare fees.

### Should I pick an earlier or later date than my retirement year?
You can. An earlier date holds more bonds and is calmer. A later date holds more stocks and swings more. People who want a bit more or less risk than average sometimes move one step either way.

### Do target-date funds pay out income in retirement?
Not on their own. You sell shares or take withdrawals as you need money. The fund does not promise a set income, and its value can still fall after the target date.

## Do this today
Log in to your 401(k) or IRA and check whether you own a target-date fund. Note its year, its expense ratio and its current stock percentage. If you also own other funds in that account, add up your total stock share.
