What the math is really doing
The catch: consolidation works on paper only if you don't run the old cards back up. Most people who consolidate end up with the original balances plus a new loan within 24 months. Cut up the cards or leave them in a drawer.

The Unburden app compares consolidation against Snowball, Avalanche, and Momentum — so you know whether a new loan is worth the credit inquiry.

Should you consolidate your debt?

Debt consolidation rolls multiple debts into a single new loan, ideally at a lower interest rate. On paper, that means one payment, one rate, one timeline. But whether it actually saves you money depends on the math behind the offer you receive.

When consolidation makes sense

Consolidation tends to work when three conditions are true. First, the consolidation loan rate is meaningfully lower than the weighted average rate of your current debts. Second, you commit to a term that does not stretch your payoff timeline so far that the interest savings vanish. Third, you stop using the credit cards you just paid off.

If you have five cards at 22-26% APR and you qualify for a personal loan at 10%, the interest savings are real and significant. You also get the psychological benefit of a single predictable payment and a fixed payoff date, which removes the ambiguity that makes debt feel unmanageable.

When consolidation backfires

A lower rate does not automatically mean less total interest. If your consolidation loan stretches the payoff from 30 months to 60 months, you are paying interest for twice as long. Even at half the rate, the total cost can end up higher. This is the single most common trap in debt consolidation.

Origination fees are the second trap. Most personal consolidation loans charge between 1% and 8% of the loan amount upfront. On a $20,000 consolidation, that is $200 to $1,600 added to your balance before you make a single payment. This calculator does not factor in origination fees, so the real cost of consolidation is likely higher than what you see here.

The third trap is behavioral. Once your credit cards are paid off, they have available credit again. Studies show that a significant percentage of people who consolidate end up running balances back up on the same cards, leaving them worse off than before.

Consolidation vs. the avalanche method

Before consolidating, it is worth comparing what would happen if you attacked your debts aggressively with the money you already have. The avalanche method targets your highest-rate debt first while making minimums on everything else. With enough extra payments, avalanche can sometimes beat consolidation on total interest without requiring a new loan, a credit inquiry, or origination fees.

What this calculator does not tell you

This calculator provides a clean side-by-side comparison of current debts versus a consolidation loan, but it leaves out several important factors. It does not include origination fees or balance transfer fees. It does not account for variable rates that may increase over the loan term. It does not assess whether you qualify for the rate you entered. And it does not factor in the credit score impact of opening a new account and closing old ones.

For these reasons, the numbers here are a starting point, not a decision. Use them to understand the general direction, then consult with a financial advisor or Licensed Insolvency Trustee if your situation is complex.

What is the Burden Score?

Your credit score measures your value to lenders. The Burden Score measures your risk to yourself. It is a 0-100 score built on five proprietary stress signals that capture how much pressure your debt is actually putting on your life. A 780 credit score and a Critical Burden Score can exist on the same person.

This calculator can tell you whether consolidation makes financial sense. The Burden Score tells you how vulnerable you are right now. You can find yours free in the Unburden app in about 60 seconds.

Common questions

Is debt consolidation a good idea?
Debt consolidation can be a good idea if you qualify for a lower interest rate than the weighted average of your current debts and you commit to not running up new balances. It simplifies multiple payments into one and gives you a fixed payoff date. However, if the consolidation loan has a longer term, you may pay more in total interest even at a lower rate. Run the numbers with Unburden's debt consolidation calculator before deciding.
Does debt consolidation hurt your credit score?
Applying for a consolidation loan triggers a hard credit inquiry, which can temporarily lower your score by a few points. However, consolidation can improve your credit over time by reducing your credit utilization ratio (if you keep old cards open with zero balances) and by establishing a consistent on-time payment history. The biggest risk is running up new balances on the cards you just paid off.
What are consolidation loan fees?
Most personal consolidation loans charge an origination fee between 1% and 8% of the loan amount. Some lenders also charge prepayment penalties if you pay off the loan early. Balance transfer credit cards may charge a transfer fee of 3% to 5%. These fees are often rolled into the loan balance, increasing the total amount you owe. This calculator does not factor in fees, so your actual cost may be higher.
What is the difference between consolidation and refinancing?
Debt consolidation combines multiple debts into a single new loan. Refinancing replaces one existing loan with a new loan at different terms. In practice, consolidation is a form of refinancing. The key difference is scope: refinancing typically refers to replacing one loan (like a mortgage or auto loan), while consolidation refers to combining several debts (like credit cards, medical bills, and personal loans) into one.
What is the Burden Score?
The Burden Score is a 0-100 financial vulnerability score available free in the Unburden app. Your credit score measures your value to lenders. Your Burden Score measures your risk to yourself. It captures how much pressure your debt is actually putting on your life. A 780 credit score and a Critical Burden Score can exist on the same person.

Disclaimer: Unburden is a planning tool, not a financial advisor. The calculations above are estimates based on the information you provide and assume consistent monthly payments at fixed interest rates. Actual results will vary based on individual circumstances, rate changes, fees, and payment behavior. This calculator does not factor in origination fees, balance transfer fees, or other loan costs. The Burden Score is an educational estimate, not financial advice. If you are struggling with debt, consider speaking with a Licensed Insolvency Trustee.

Consolidation is one path. Compare payoff strategies and find your Burden Score before applying for a new loan.
