Pay the Debts in This Order
There are two methods, one is mathematically better and the other one people actually finish. Plus what to do about a collection account, which follows different rules entirely.

THE SHORT VERSION
The avalanche method pays the highest interest rate debt first and saves the most money, while the snowball method pays the smallest balance first and is completed more often because early wins sustain momentum. Debt in collections follows separate rules: collectors must validate the debt in writing on request, and acknowledging or partially paying an old debt can restart the statute of limitations.
There are two respectable ways to pay off debt and one enormous trap sitting next to them. Take them in order.
Avalanche. List every debt by interest rate, highest first. Pay minimums on everything, and put every spare dollar at the top of the list. When it clears, move to the next.
This is mathematically optimal. It costs the least money and it finishes soonest in theory.
Snowball. List by balance, smallest first. Same process: minimums everywhere, everything spare at the smallest one.
This costs slightly more in interest and people finish it far more often, because clearing a whole account in six weeks produces momentum that a spreadsheet does not.
The right answer is not the one with better arithmetic. It is the one you will still be doing in eight months. If you have tried and stalled before, run the snowball.
Once a debt is sold to a collector the rules change, and the rules favour you more than people realise.
Demand validation in writing. You have the right to request that a collector verify the debt. Do it in writing, keep a copy, and do not pay anything until they do. Debts are sold repeatedly in bulk and records get lost, so a meaningful share cannot be validated at all.
Check the statute of limitations before you speak to anybody about an old debt. Every state sets a period after which a debt cannot be enforced in court. Here is the trap: in many states acknowledging the debt or making a partial payment can restart that clock entirely, reviving something that was legally unenforceable. A collector calling about a very old debt and offering a friendly small payment plan may be doing exactly this.
Know what they cannot do. Under federal law collectors may not threaten arrest, call at unreasonable hours, contact you at work after you tell them not to, or discuss your debt with your family. Log every call with date and time.
Get it in writing before you pay. If you negotiate a reduced payoff, get the agreement in writing first, including what they will report to the credit bureaus.
“A collector is buying a chance. Make them prove what they bought before you fund it.”
Debt settlement firms charge substantial fees to do what you can generally do yourself, and their standard method involves having you stop paying entirely while they accumulate funds, which damages your credit and can trigger lawsuits in the meantime.
If you want help, a nonprofit credit counselling agency is the different and better option, and a free legal clinic is free if you are being sued.
When it clears, check that the report reflects it. Paid collections do not always update on their own.
- Should I use the avalanche or snowball method?
- Avalanche, paying the highest interest rate first, saves the most money. Snowball, paying the smallest balance first, gets completed more often because early wins build momentum. If you have stalled on a payoff plan before, the snowball is usually the better bet.
- What is debt validation?
- Your right to require a collector to verify in writing that the debt is yours and that they can collect it. Request it in writing, keep a copy, and pay nothing until they respond. Debts are sold repeatedly in bulk and a meaningful share cannot be validated.
- Can paying an old debt make it worse?
- It can. Every state has a statute of limitations after which a debt cannot be enforced in court, and in many states acknowledging the debt or making a partial payment restarts that clock, reviving something that was legally unenforceable. Check the limitation period before speaking to a collector about an old debt.
- Are debt settlement companies worth it?
- Generally no. They charge substantial fees for negotiations you can usually conduct yourself, and their typical method has you stop paying entirely while funds accumulate, which damages credit and can lead to lawsuits. Nonprofit credit counselling is the better alternative.
