Rolling a paid-off debt’s payment into the next one

Key points

• When a debt is paid off, its monthly payment is freed up.
• Rolling payments over to your next debt, instead of spending them, speeds up everything after.
• Your total monthly outlay stays the same, so you don’t need a bigger budget.
• It works with any payoff order, including snowball and avalanche.

The moment that matters

Clearing a debt feels great. It also hands you a decision, because the money you were paying on it each month is suddenly free.

The easy thing is to let it drift into everyday spending. You’ve been stretching for a while, after all. But move that exact amount to your next debt and the payment on that debt grows straight away. When that one’s cleared, both payments move on to the next. And so on down the list.

This is the engine behind both the snowball and avalanche methods. Without it, each debt just limps along on its own schedule.

A worked example

Here are three debts, each with a fixed minimum payment. The same maths works in any currency.

Total paid each month: $430. No extra on top.

Assumptions: interest is charged monthly at the yearly rate divided by 12, on the balance before that month’s payment. Payments are fixed. No new spending goes on the debts. The last payment on each debt is whatever clears it.

Without rolling payments over, each debt is paid off on its own. Card A is cleared in month 47, the loan in month 52, and Card B drags on until month 82. Total interest: $9,316.71.

With rolling payments over, targeting Card B after Card A, the first two finish at the same points. Card A is cleared in month 47 and its $60 moves to Card B. The loan is cleared in month 52 and its $220 also moves to Card B. Now Card B is cleared in month 60. Total interest: $8,448.41.

Same debts. Same $430 a month while there’s debt to pay. Rolling the payments over finishes 22 months sooner and saves $868.30 in interest.

And that’s with no extra at all. The same three debts with $650 a month, rolled over, are cleared in 32 or 33 months depending on the order.

Why rolling payments over works so well

Two things happen when you roll a payment over. First, the next debt gets a much bigger payment. In the example, Card B’s payment jumps from $150 to $210, then to $430.

Second, every rolled-over dollar goes to the balance. The next debt’s interest is already covered by its own payment, so the extra cuts the balance directly, and that cuts future interest too.

The later debts gain the most. By the time you reach them, several payments have stacked up.

Making it happen

The maths is the easy part. The hard part is making sure the money actually moves.

• Change the payment the same week. As soon as a debt is cleared, raise the payment on your next target by the freed-up amount.
• Automate the new amount. If your payments are automatic, update them so nothing relies on memory.
• Decide your next target in advance. Know which debt comes next before the current one is done. Smallest balance first and highest rate first are both common choices.
• Watch for loans ending on their own. Fixed-term loans, like car loans or personal loans, finish on a set date. Mark it so you can roll that payment over too.

What about rewarding yourself?

Some people keep a small slice of a freed-up payment as a reward and roll the rest. That can make the plan easier to keep going. The cost is a slightly later finish. Whether it’s worth it depends on what helps you stick with it.

When you’re on the last debt

Once the final debt is cleared, the full amount you’ve been paying is yours again. Some people keep the habit alive by moving some or all of it to savings, such as an emergency fund. Others enjoy having the room back in their budget. You’ve earned the choice.

Common questions

What does rolling payments over mean?

When a debt is paid off, you move its monthly payment to your next debt instead of spending it. Your total monthly outlay stays the same.

Does rolling payments over work without paying extra?

Yes. In the example above, with no extra at all, rolling the payments over finished 22 months sooner and saved $868.30 in interest.

What can I do with the money after the last debt is paid?

Some people move some or all of it to savings, such as an emergency fund. Others enjoy having the room back in their budget.
