The idea

Two well-known repayment strategies help people with several debts. In both, you keep paying the minimum on every debt and put any extra toward one debt at a time. The avalanche method targets the debt with the highest interest rate first; it saves the most money overall. The snowball method targets the smallest balance first; it clears whole debts sooner, which many people find motivating.

Refinancing means replacing one or more debts with a new one on better terms — a lower rate, or one payment instead of several. It can reduce costs, but it can also extend the time you are in debt or add fees, and combining debts only helps if you stop adding new ones. Offers to “make debt disappear” for a fee deserve great caution; where debt feels unmanageable, free, regulated debt-advice services exist in many countries.

Why it matters

A clear repayment plan turns a heavy, shapeless burden into steps with an end in sight — the most important change for anyone in debt.

A real example

The situation

Kemi has four debts and has been paying a little extra on all of them, with slow progress.

What happened

She lists them by interest rate and puts all her extra into the most expensive one while paying minimums on the rest. When it is gone, she rolls its payment into the next. Progress speeds up month by month.

The takeaway

Focusing the extra payment on one debt at a time made the plan move.

How people actually behave

People with several debts tend to spread extra payments evenly, which feels fair but slows progress, and to respond to whichever lender is loudest rather than whichever debt is most expensive.

Common mistakes

• Spreading extra payments thinly across every debt.
• Refinancing and then running balances up again.
• Paying for debt services that promise results that free advice could provide.

Questions to think about

• Would you rather save the most money, or feel progress sooner?
• Which of your debts would each method target first?

Try it: Make your plan

1. List each debt with its balance, interest rate and minimum payment.
2. Choose avalanche (highest rate first) or snowball (smallest balance first).
3. Put every extra amount on your target debt until it is gone, then move to the next.

Words in this lesson

• Debt avalanche — A repayment method that pays the minimum on every debt and puts any extra toward the debt with the highest interest rate first.
• Debt snowball — A repayment method that pays the minimum on every debt and puts any extra toward the smallest balance first.
• Refinancing — Replacing one or more debts with a new one on different terms, such as a lower rate or a single payment.
