Smallest Balance First or Highest Rate First? Comparing Payoff Orders

When several debts are competing for the same extra dollars, which one gets the next payment? Two ordering rules come up most often. One pays the smallest balance first. The other pays the highest interest rate first. Neither is right for everyone, and the gap between them is often smaller than people expect. What differs is how each feels along the way and what it costs in total.

Key takeaways

• Both common payoff orders keep minimum payments going on every debt and send the extra money to one target debt at a time.
• Paying the highest interest rate first usually costs less in total interest, while paying the smallest balance first tends to clear individual debts sooner.
• In a hypothetical household, the two orders finished everything in the same month and differed by roughly $120 in total interest.
• The Consumer Financial Protection Bureau describes both approaches and says the better fit depends on whether the priority is saving the most money or seeing progress quickly.
• The gap between the two orders depends on how far apart the rates are and how large the balances are, so the same comparison can look very different for another household.

How the two orders work

Both approaches start the same way. Every debt gets at least its minimum payment each month, so nothing goes delinquent. Any money beyond the minimums is then aimed at a single target debt.

• Smallest balance first targets the debt with the lowest balance, whatever its rate. When that debt is paid off, its full payment moves to the next-smallest one, so the amount aimed at each target grows over time.
• Highest interest rate first targets the debt with the highest rate, whatever its size. When that one is gone, the money moves to the next-highest rate.

The Consumer Financial Protection Bureau describes both approaches. It notes that the highest-rate order can save money over the long run but progress may feel slow, while the smallest-balance order produces quick wins but may cost more because larger or more expensive debts keep growing in the meantime.

A worked comparison

Consider a hypothetical household with three debts:

• A $1,000 personal loan at 8 percent, with a $50 minimum.
• A $3,000 credit card balance at 24 percent, with a $90 minimum.
• An $8,000 car loan at 6 percent, with a $200 minimum.

The minimums add up to $340 a month. Suppose the household can add $150 more, for $490 in total, and keeps that total fixed until everything is paid.

With the smallest-balance order, the $1,000 loan is gone in month 6, the card in month 17, and the car loan in month 28. Total interest is about $1,381.

With the highest-rate order, the card is gone in month 15, the loan in month 16, and the car loan in month 28. Total interest is about $1,259.

So in this example both orders finish together, and the difference is roughly $122. The smallest-balance order delivers a finished debt in month 6, while the highest-rate order takes until month 15 to deliver its first.

This example leaves out fees, rate changes, new charges, promotional rates and minimum payments that can shrink as balances fall. It holds each minimum fixed to keep the comparison simple. A household with a larger gap between rates, or with a very large balance at a high rate, would likely see a bigger difference than this one.

What each order tends to trade away

The smallest-balance order trades some interest for visible progress. Closing out an account can also reduce the number of bills to track, which some people find makes it easier to keep going.

The highest-rate order trades early momentum for lower cost. If the high-rate balance is also large, the first payoff can take a long time, and it can be hard to see progress.

When the smallest balance and the highest rate happen to belong to the same debt, the two orders are the same and the choice disappears.

Questions that can help clarify the choice

1. How far apart are the interest rates? A narrow spread tends to make the dollar difference small.
2. How large is the highest-rate balance compared with the smallest one? A very large high-rate balance can mean a long wait for a first payoff.
3. Has the household started and stopped repayment plans before? If so, early wins may matter more than the last few dollars of interest.
4. Are any of the debts different in kind, such as a secured loan, a loan with a prepayment term, or a balance with a promotional rate that is about to end?
5. Is there a cash cushion in place, so that a surprise bill does not push the household back onto a card?

The Consumer Financial Protection Bureau frames the choice as a matter of priorities: the highest-rate order for someone mainly after savings, the smallest-balance order for someone who wants quick progress. Either helps only if it is followed. A written list of every debt, its balance, its rate and its minimum payment makes either order easier to run, and makes it easy to see when it is time to move to the next target.

Some households also combine the two ideas, for example by clearing one or two very small balances quickly and then moving to the highest rate. That is a personal choice with its own trade-offs, and it can be reasoned through with the same questions.

Common questions

What is the difference between the debt snowball and the debt avalanche?

Both methods pay the minimum on every debt and put extra money toward one debt at a time. The snowball targets the smallest balance first, and the avalanche (the highest interest rate method) targets the debt with the highest rate first.

Which method saves more money?

Targeting the highest interest rate first generally results in less total interest, because the most expensive balance shrinks sooner. How much less depends on the rates and balances involved, and the difference can be small.

Can motivation really matter more than the math?

A plan only works if it is followed. The Consumer Financial Protection Bureau says the smallest-balance order may suit people who want quick progress, while the highest-rate order may suit those focused on saving the most money.
