Debt Strategy Planner

Compare different ways to pay down debt and see how they change total interest, monthly payments, and the time it takes to become debt free.

Starting scenario:
CC1: $10,000 @ 15% CC2: $7,500 @ 18% Car: 12 of 60 paid Mortgage: 40 of 360 paid
This page compares different payoff goals from that same starting point.
Main Points
We start with a real debt mix. Two credit cards, a car loan, and a mortgage give each goal the same starting point.
High-interest debt usually costs the most over time. Paying a 18% credit card is like earning a guaranteed 18% return.
Paying off a debt completely improves cash flow. Once a payment disappears, that monthly amount can be rolled into the next target.
The best payoff goal depends on what you want most. One goal may save the most interest, another may create quick wins, and another may free monthly money faster.
Credit cards usually come first. Then car loans, and mortgages usually last.

Deep Dive

What is a debt payoff strategy?

When you have more than one debt, you need to decide how to split your money between them. The minimum payments still go to every debt, but any extra money goes to just one. A debt payoff strategy is the rule you use to pick which debt gets the extra money first.

Two strategies are most common: the avalanche method and the snowball method.

The avalanche method

The avalanche method puts extra money toward the debt with the highest interest rate first. When that debt is gone, you roll all of its payment plus the extra into the debt with the next-highest rate. You repeat this until everything is paid off.

Avalanche almost always saves the most money in total interest. Higher-rate debt is more expensive every month it sits there, so attacking it first cuts interest costs the fastest.

The snowball method

The snowball method puts extra money toward the debt with the smallest balance first, no matter the rate. When that debt is gone, you move on to the next-smallest, then the next.

Snowball usually costs slightly more in total interest than avalanche, but it gives faster wins. Watching individual debts disappear can be motivating, which helps people stick with the plan.

Why interest rate matters so much

Interest is charged on the balance every month. A $5,000 balance at 22% costs about $92 a month in interest alone. A $5,000 balance at 6% costs about $25. Same balance, very different cost. That is why the avalanche method targets the highest-rate debt first — every dollar paid against a high-rate balance saves more than a dollar paid against a low-rate balance.

Minimum payments and the trap

Most debts require a minimum monthly payment. On credit cards, the minimum is usually just enough to cover interest plus a tiny piece of principal. Paying only the minimum can stretch a balance out for decades and cost more in interest than the original purchase amount.

Any extra money above the minimum goes straight to principal, and that principal is what generates the interest. Reducing it has compounding benefits.

The "freed up" payment effect

Once a debt is paid off, its monthly payment is freed up. In a structured plan, that freed-up money rolls into the next debt's payment, which pays it off even faster. Each payoff makes the next one happen sooner. This is why both avalanche and snowball get faster as they go.

Avalanche vs. snowball: which wins?

On paper, avalanche almost always wins on total interest. In practice, the best strategy is the one you will actually stick with. If quick wins keep you motivated, snowball may be the right pick. If you are confident you will follow through, avalanche saves the most money.

Common misconceptions

Some people focus on the size of the balance rather than the interest rate. A small balance at 25% can be more expensive each month than a much larger balance at 4%. The interest rate is usually the better signal of which debt is hurting you most.

People also assume that consolidating debt is always a good idea. Consolidation only helps if the new rate is meaningfully lower and you stop adding new debt to the cards you paid off.

Key takeaway

A structured plan beats random extra payments. Pick a strategy, focus your extra dollars on one debt at a time, and roll each payoff into the next debt. Avalanche saves the most in interest. Snowball gives the most motivation. Either one beats paying only the minimums.
