# Should you pay off debt or invest?

> Take the 401(k) match, pay off high-rate debt next, then invest. For low-rate debt, do both at once.

Get any employer 401(k) match first, then pay off high-interest debt like credit cards before investing more. For low-rate debt, like a 4% car loan or mortgage, investing alongside the minimum payments usually makes sense, because the expected return can beat the rate, though it is never certain.

## Key facts
- **A paid-off debt is a sure return.** The SEC's investor education office says no investment strategy pays off as well as, or with less risk than, eliminating high-interest debt. Investment returns vary and can be negative. A paid-off balance can't lose value.
- **The match comes first.** If your employer matches 401(k) contributions, put in at least enough to get the full match before paying extra on debt. Skipping it leaves part of your pay on the table.
- **Rates decide the middle ground.** Debt above about 8% usually beats any return you can count on, so pay it first. Below about 4% to 5%, investing alongside the minimum usually wins over long periods. In between, splitting your extra money is reasonable.
- **Your feelings count too.** Some people sleep better with no debt, even at a low rate. Paying a 5% loan early instead of investing costs some expected growth, but it is never a bad use of money.

## The order that works for most people
First, save a small emergency fund of about $1,000 so a surprise doesn't land on a card. Second, put enough in your 401(k) to get the full employer match. Third, pay off high-interest debt, like credit cards and personal loans at double-digit rates.
Fourth, grow the emergency fund to 3 to 6 months of essentials. Fifth, invest for retirement, often aiming for 15% of income including any match. Pay low-rate debt like a mortgage or a low-rate car loan on schedule along the way.

## How to compare a debt with an investment
A debt's interest rate is a known cost. An investment's return is a guess about the future. A broad stock index fund has gone up over long periods in the past, but it can fall 20% or more in a single year, and past returns don't promise future ones.
That is why the comparison isn't simply 7% versus 6%. A sure 6% from paying off a loan is worth about as much as a higher, uncertain return. The bigger the gap between the debt rate and what you expect to earn, the clearer the choice.

## Credit cards and other high-rate debt
Credit card rates are often 20% or more. No realistic investment return beats that reliably. Once you have the match and a starter emergency fund, every extra dollar should go to the highest-rate balance first.
Use the avalanche method (highest rate first) to save the most interest, or the snowball method (smallest balance first) if quick wins keep you going. Either one is better than spreading extra money across everything.

## Student loans, car loans and mortgages
These usually have lower rates, often under 8%. For a loan around 3% to 5%, paying the minimum and investing the extra usually comes out ahead over long periods, though not every year.
Federal student loans have extra things to weigh. Income-driven repayment and forgiveness programs can change the math, so paying extra on a loan that may be forgiven could be wasted. Check your options with your loan servicer and on the Federal Student Aid site before you prepay.

## When a split makes sense
If your debt is in the middle, around 5% to 8%, you don't have to choose one. Put half of your extra money toward the debt and half into investing. You make progress on both and avoid the regret of guessing wrong.
Revisit the choice when something changes: a raise, a new loan, a rate change on a variable loan or a big drop in the market. The plan should follow your rates and your goals.

## A worked example: card first or invest first
Chris has $650 a month to split between a $4,000 card at 24% APR and an index fund. He already gets his 401(k) match. Assume the fund earns 7% a year, which is not certain.

- Card interest, $650/mo to card: $312
- Card interest, $150/mo to card: $1,773
- Debt first: invested at month 39: $23,081
- Invest first: invested at month 39: −$21,902
- Debt first comes out ahead: = $1,179

1. Debt first: all $650 goes to the card, which is gone in 7 months with $312 of interest. Then $650 a month goes into the fund.
2. Invest first: $150 to the card for 39 months ($1,773 of interest) and $500 a month into the fund.
3. After 39 months the card is paid either way. Debt first has $23,081 invested, invest first has $21,902. $23,081 − $21,902 = $1,179.

## Common mistakes
- **Skipping the match to pay debt.** An employer match is usually worth more than any debt rate. Stopping contributions to pay a card faster gives up money you can't get back.
- **Investing with a high-rate balance.** Earning an uncertain return while paying a sure 24% on a card almost always loses. Clear the card first, then invest the freed-up payment.
- **Emptying savings to pay debt.** Paying off a card with every dollar you have feels great until the car breaks. Keep a starter emergency fund so the debt doesn't come right back.

## Questions people ask
### Should I pay off my car loan early or invest?
Compare the rate. Under about 4% to 5%, investing the extra usually wins over time. Above about 8%, paying it off first usually makes more sense. Check that your loan has no prepayment penalty.

### Should I stop contributing to my 401(k) to pay off debt?
Keep at least enough to get the full employer match. Above the match, pausing extra contributions for a short time to clear high-interest debt can make sense, then restart and increase them once the debt is gone.

### Is it smart to pay off my mortgage early?
It depends on the rate and your goals. With a low fixed rate, many people invest instead. Paying early still gives a sure return equal to the rate and lowers your monthly costs once it is paid, which some people value more.

### What about investing while paying off student loans?
For low-rate federal loans, investing alongside the payments often makes sense, especially if you may qualify for forgiveness. For private loans above about 8%, paying them down faster usually wins.

## Do this today
Write down every debt with its APR. Check that you are getting your full 401(k) match. Then pick the highest-rate debt above about 8% and set an extra automatic payment toward it for your next payday.
