Paying Off Debt: Avalanche vs Snowball, Which One Fits You

Tim Moneysaurus · 2026-07-19

Debt is not a sign that you failed, but left to pile up it can feel like a hole that keeps getting deeper. Usually the problem is not that you are lazy about paying. It is that you do not know where to start: which debt to attack first so you get free faster and lose less to interest. Two popular methods can serve as your map, the avalanche and the snowball. Both are valid, and the best one is simply the one you will actually finish.

Installment debt is now normal, and the interest is no joke

Digital consumer debt is part of everyday life in Indonesia. Bank paylater balances alone hit Rp22.57 trillion as of January 2025, up 46.45% year on year across 24.44 million accounts (OJK via CNN Indonesia). That excludes pinjol, personal loans, and credit cards.

What makes debt heavy is the interest. For credit cards, Bank Indonesia keeps the ceiling at 1.75% per month, roughly 21% per year (Bank Indonesia via Antara). Online lending is higher still: OJK caps short-tenor consumer loans at 0.3% per day, which can add up to around 9% a month (CNBC Indonesia). The order you pay in matters, because every month you delay, interest keeps running.

Avalanche: chase the highest rate, save the most money

The avalanche method tells you to pay the minimum on every debt, then throw all your spare cash at the debt with the highest interest rate first. Once it is cleared, that money rolls to the next highest rate. Mathematically, this saves the most total interest and gets you debt free fastest.

The most powerful way to see it: paying off high-interest debt is a risk-free investment. If your credit card charges 21% a year, clearing it locks in a guaranteed 21% return. No mutual fund or stock will promise that without risk. So a rupiah used to kill a pinjol or credit card balance almost always works harder than a rupiah you save.

Avalanche fits you if you are disciplined and the gap between your interest rates is wide, for example a 9%-a-month pinjol sitting next to a 0% paylater installment.

Snowball: chase the smallest balance, win through momentum

The snowball is the opposite. You pay the minimum on everything, then pour your spare cash into the smallest balance first, ignoring the interest rate. The moment a debt disappears, that small win keeps you motivated to attack the next one.

It sounds less clever mathematically, but there is research behind it. A study by Gal and McShane in the Journal of Marketing Research found that the strongest predictor of fully escaping debt was how many debt accounts a person managed to close, not the dollar size of what they closed (Gal & McShane, 2012). Small victories preserve motivation, and motivation is often what decides whether a payoff plan finishes or stalls halfway.

Snowball fits you if your biggest enemy is not interest but consistency. If you often feel worn out and give up, momentum is worth more than saving a few thousand rupiah.

A concrete example

Say you have three debts and can spare an extra Rp1 million a month above your minimums. The numbers below are just illustration.

With avalanche, the extra goes to the pinjol first (highest rate), then the card, then the paylater. You pay the least total interest. With snowball, you clear the Rp800k paylater first for an early win, then the pinjol, then the card. Slightly more expensive, but you get the psychological boost sooner.

The real key: automate it, do not rely on willpower

Even the best method fails if it depends on weekly willpower. Behavior beats information every time. So once you pick a method, set up an autodebit for the extra payment right after payday, before the money drifts elsewhere. What runs on autopilot is what actually gets done.

And to make the choice data-driven, you need to know exactly which debt drains you most. Logging your spending and installments can be as easy as texting "paid pinjol 500k" to Moneysaurus on WhatsApp, so your debt numbers stay in plain sight.

One last thing: paylater or pinjol debt is nothing to be ashamed of, and you do not need to punish yourself. You only have one real decision to make, which method you are most likely to see through to the end. If you are disciplined and the rate gap is wide, choose avalanche because it saves the most. If you need momentum to keep going, choose snowball. The best method is not the smartest on paper, it is the one that actually gets you to zero.
