How to Get Out of Debt: The Definitive Step-by-Step Guide

CoinSim Team··9 min

The debt that never seems to shrink

Picture this: you have $4,000 on a credit card. Not because you went on a spending spree — it built up gradually. A car repair here, a security deposit there, a few months where the card was the only option. Now you pay the minimum every month — around $80 — and the balance barely moves. Some months it actually goes up.

That's not bad luck. That's math.

Most consumer credit cards in the US carry APRs between 20% and 30%. In the UK, standard credit card rates typically run 20–25% APR. That means each year you owe 20–30% more in interest alone, regardless of what you pay. If you only pay the minimum on a $4,000 balance at 24% APR, you'll spend over 15 years paying it off and hand the bank more than $4,000 in interest alone.

The good news: getting out of debt doesn't require earning more money. It requires a plan.

Why your debt keeps growing even when you're "barely spending"

The real enemy isn't how much you owe — it's compound interest working against you.

Here's how it works: every month, the lender calculates interest on your remaining balance. If you don't pay enough to cover that interest, it gets added to the principal. Next month, you pay interest on a larger balance. And so on.

With a credit card at 24% APR:

  • Month 1: You owe $4,000. Monthly interest: ~$80
  • If you pay $85, you only reduce the debt by $5
  • Month 2: You owe $3,995. Interest is still ~$80
  • After 12 months of $85/month payments: you still owe ~$3,940

This is the reverse snowball effect. The feeling that you're "never making progress" is completely valid — because mathematically, you aren't.

The fix is to pay meaningfully more than the minimum. But when you have multiple debts, which one do you attack first?

The debt snowball method

Popularized by Dave Ramsey, the debt snowball method works on a simple psychological principle: start with the smallest balance to get quick wins.

How it works:

  1. List all your debts from smallest to largest balance
  2. Pay the minimum on everything except the smallest debt
  3. Throw every extra dollar at the smallest debt
  4. When it's gone, roll that payment into the next one

Real example with three debts:

DebtBalanceAPRMinimum
Store card$90026%$25
Personal loan$3,00011%$75
Credit card$6,00022%$120

You have $380/month for debt payments. Pay the minimums on the loan ($75) and credit card ($120), and direct everything else to the store card: 380 - 75 - 120 = $185/month toward $900.

In about 5 months the store card is gone. Now you have $185 free to stack onto the personal loan: 75 + 185 = $260/month. You'll clear it in roughly 11 more months. Then the full $380 goes at the credit card.

When to use it: when you need motivation and momentum. Eliminating entire debts quickly keeps you going. Especially useful if you have many small debts causing anxiety.

The debt avalanche method

The avalanche method optimizes mathematically: attack the highest interest rate first, regardless of balance size.

How it works:

  1. List all your debts from highest to lowest interest rate
  2. Pay the minimum on everything except the highest-rate debt
  3. Throw every extra dollar at the most expensive debt
  4. When it's gone, move to the next highest rate

With the same example: Order is now: store card (26%), credit card (22%), personal loan (11%).

Even though the store card is only $900, its 26% rate makes it the mathematical priority. Attacking it with $185/month clears it in ~5 months. Then you stack onto the credit card (22%) — the next most expensive.

When to use it: when you have the discipline to ignore the number of debts and only care about minimizing total interest paid. Over time, the avalanche method saves more money than the snowball method.

Which should you pick? If you need motivation: snowball. If you want to mathematically optimize: avalanche. Both work. The only method that fails is the one you abandon.

Your 90-day plan starting today

You don't need a perfect spreadsheet or a financial advisor. You need this:

Week 1 — Diagnosis:

  • List every debt: lender, balance, interest rate, minimum payment
  • Calculate your real monthly spending (add up the last 3 months of bank statements)
  • Identify how much you can put toward debt each month beyond the minimums

Week 2 — Decision:

  • Choose your method (snowball or avalanche)
  • Set up automatic transfers on payday so you can't accidentally spend that money
  • Temporarily cut or pause non-essential subscriptions and discretionary spending

Weeks 3–4 — Execution:

  • Make your first large payment
  • Use our debt calculator to calculate exactly when you'll be debt-free at different monthly payment amounts
  • Write down the estimated payoff date for your first target debt — that's your first concrete goal

Months 2–3 — Consolidation:

  • Check your priority debt balance weekly
  • If you receive any unexpected money (tax refund, gift, side income), send it directly to the debt
  • Celebrate milestones: not with spending, but by acknowledging the progress

The 3 mistakes that add years to your debt

1. Only paying the minimum

This is the most expensive thing you can do. The minimum payment is designed to maximize the time you're in debt and maximize what the lender collects. Never pay only the minimum if you can pay more.

2. Consolidating without changing behavior

Rolling all your debts into a lower-rate personal loan can be smart — but only if you simultaneously fix the habits that created the debt. If you consolidate and keep using your credit cards the same way, in 12 months you'll have the loan plus new card debt on top.

3. Not prioritizing high-interest debt first (if using the avalanche)

Paying off a $6,000 loan at 9% before a $1,200 card at 26% feels intuitive because the loan is "bigger." But you're paying double the interest unnecessarily. The interest rate is the real cost of the debt, not the balance.
