Debt snowball vs avalanche: pay off debt faster

Put every debt on the table first

Before arguing about order, you need the full list. In an Algerian household that list often mixes instalments on a fridge or a telephone, a consumer loan from the bank, money owed to a brother or a cousin, perhaps a car on leasing. A daret share you have received is a commitment too — the circle expects its money on the next turn.

• The balance left today, not the original amount borrowed.
• The yearly interest rate, or the real cost of the instalment plan.
• The minimum payment, and the day of the month it falls due.

Interest on bank credit in Algeria is moderate. The average effective rate on consumer loans was about 9.6% in the first half of 2025, and the Bank of Algeria capped the threshold for consumer credit at 10.36% for the first half of 2026, with leasing allowed a little more. Shop instalments that look free are not always free: fees and the gap between the cash price and the instalment price change the real bill, which we break down in Buying on instalments in Algeria: the real cost . Family debts usually carry no rate at all — they carry a relationship instead. One rule comes before any clever ordering: pay at least the minimum on every debt, every month. Late fees, a blocked account at the shop or trouble with the bank cost more than any plan saves.

The snowball: clear the smallest debt first

The snowball orders your debts by balance, not by rate. You settle the smallest account completely, then roll everything you were paying on it into the next-smallest, like a snowball gathering size as it rolls downhill.

1. List your debts from the smallest balance to the largest.
2. Pay the minimum on all of them.
3. Throw every spare dinar at the smallest debt until it is gone.
4. Roll its whole payment onto the next-smallest debt.
5. Repeat until the list is empty.

The snowball's strength is not mathematics, it is morale. Closing a whole account — the phone, the tab at the epicerie, the 20 000 DA you owe a friend — is a visible victory within weeks, and each closed debt frees money that makes the next one fall faster. It suits months when money is tight, or when several small debts are weighing on your mind.

The avalanche: attack the dearest interest first

The avalanche orders your debts by rate. The interest is what makes a debt expensive, so every spare dinar goes to the most expensive one first while the others coast on their minimums.

1. List your debts from the highest rate to the lowest.
2. Pay the minimum everywhere.
3. Send every spare dinar to the debt with the highest rate.
4. Roll its payment into the next-dearest debt when it falls.
5. Repeat until the list is empty.

This is the cheapest order on paper, because the dinars that cost you the most stop costing immediately. Its weakness is patience: the dearest debt may also be the biggest, and you can spend many months grinding on one account without ever writing the word "closed".

A worked example in dinars

Meet Karim, who brings home 70 000 DA a month. Between rent, food, transport and the fixed bills, he can dedicate 24 500 DA a month to his debts: the two minimums plus 10 000 DA extra. His list looks like this.

We kept the arithmetic deliberately simple: interest recalculated each month on what remains, at 10% a year for the shop instalments and 9.5% for the loan, in line with the Bank of Algeria figures above. Real loan schedules differ in detail; the ranking of the two orders does not. Under the snowball, Karim pays his brother 10 000 DA a month and closes that debt in month five, then turns on the shop instalments, then the loan. Under the avalanche, he crushes the shop instalments by month four, then the loan, and leaves the interest-free debt to his brother for last. Here is the scorecard.

Debt snowball vs avalanche: which one wins?

On paper the avalanche never loses: every dinar goes first where it costs the most. What the research adds is how small the usual gap is. An analysis of several thousand American households found that roughly half would finish at the same time under either order; among the rest, about a third differed by less than three months, and only one or two in a hundred by a year or more. A recent LendingTree comparison makes the same point: in its most realistic scenario the two orders ended in the same month, just $29 apart over nearly five years, while where one debt carried a much higher rate, the avalanche saved about $1 292 and a month. But finishing is not only arithmetic. Economists at Northwestern's Kellogg School, working through the records of about 6 000 people clearing debts, found that those who chased small victories — closing one account after another — were more likely to eliminate their debt entirely. A plan you abandon in month two is more expensive than a slightly dearer plan you keep for a year.

Same finish line, different bill: the avalanche hands over about 3 000 DA less, because interest never gets another month to grow on the dearest debt. The snowball buys something else — the brother paid in full by month five, a warm victory no spreadsheet prices. Choose with a few simple rules. - Rates far apart, or one debt clearly dearer and bigger: lean avalanche. - Rates close together, morale fragile, small debts nagging at you: lean snowball. - Interest-free family debts: the maths sends them last, your heart may send them first — just keep a rhythm and tell them the plan. - Undecided? Split the extra: most of it on the dearest debt, a little on the smallest, and go fully with the winner after the first account falls. One Algerian particular works in your favour: because the Bank of Algeria caps rates, the spread between one loan and another is narrow, so the pure savings from perfect ordering are modest. The order you will actually respect matters more than the order itself.

Make the plan survive a bad month

A payoff plan is easy in January and hard in the month of a wedding, a sickness or a broken compressor. Build it so it bends instead of breaking.

• Keep a small cushion before you accelerate: even 15 000 to 20 000 DA set aside means a surprise does not turn into fresh debt — see how much an Algerian household needs in Emergency fund: how much an Algerian household needs .
• Give debts their place on salary day: fixed bills first, the debt payment second, daily life with what remains — our monthly budget guide walks through it.
• Add no new instalments while you pay down: every new crédit restarts the snowball from the top.
• Any windfall — a bonus, a returned daret share, a gift — goes straight to the target debt, not to the sofa.
• If a month collapses, protect the minimums, pause the extra, and resume. Skipping a whole cycle is what turns a plan into a mess.

Remember that debt is heaviest at the start and lighter every month you stay on it: each payment shrinks the balance that interest feeds on, so progress accelerates even when the effort feels the same.

Keeping score without the notebook

Whichever order you choose, the plan lives or dies on bookkeeping. Jibi's debts and instalments section holds each debt with its balance, its minimum and its due day; you record each payment as you make it and watch what remains fall month after month. Nothing connects to your bank or to Algérie Poste — you note what you spend, and the picture stays yours. The app is free, in Arabic, French and English, on the web, on iPhone and on Android, and its monthly budget warns you before a category overshoots. A good first step is the guide Keep track of debts and instalments, without the notebook ; then open the app and enter your three numbers — balance, rate, minimum — for every debt on the list.
