When a debt consolidation loan lowers your total cost and when it doesn’t

A debt consolidation loan combines multiple debts into one single loan. This can make your payments simpler and sometimes cheaper. But not every consolidation loan lowers your total cost. You need to know when it helps and when it just moves your debt without saving money.

For example, the average 24-month personal loan rate is about 11.90% as of August 2026, according to the Federal Reserve. That’s often lower than credit card rates, which are around 22.36%. So, if you have high-rate credit card debt, a debt consolidation loan might reduce your interest costs. But if your debts are already low-rate, like some car loans or mortgages, consolidation might not save you much.

What a debt consolidation loan does

When you take one, you use the loan money to pay off multiple existing debts. Then, you make one monthly payment to the new lender. This can simplify your bills and reduce stress because you only track one payment.

The main goal is to save money by paying less interest or fees. It can also help you pay off debt faster if the loan term is shorter than your current debts. But sometimes, the loan term is longer, which lowers monthly payments but can increase total interest paid over time.

For example, suppose you have three credit card balances:

Your total monthly payment is $180. If you take a 24-month personal loan at 11.90% for $6,000, your monthly payment will be about $281. You pay more monthly, but the interest rate is much lower, so you pay off the debt faster and save on total interest. Using a loan calculator helps you see these numbers clearly.

When a debt consolidation loan lowers your total cost

It can save you money if:

• The interest rate is lower than your current debts.
• The loan term is the same or shorter, so you pay less interest overall.
• There are few or no fees for the loan or paying off your old debts.

For example, imagine you owe $5,000 on credit cards at 22% APR, paying $150 monthly. It could take over 4 years to pay off, costing you nearly $1,500 in interest. If you get a 24-month personal loan at 11.90% for $5,000, your monthly payment would be about $235, and total interest paid would be about $350. You pay more each month but save over $1,100 in interest and clear your debt faster.

Using a loan calculator can help you compare your current payments with the new loan. See our loan payment calculator to try it out.

When a debt consolidation loan just moves the debt

Sometimes, the new loan doesn’t save money. It just shifts the debt around:

• If the loan term is longer, you may pay more interest in total.
• If the interest rate isn’t much lower, savings are small or nonexistent.
• If there are high fees or penalties for paying off old debts early, costs add up.

For example, say you have $10,000 in credit card debt at 20% APR, paying $300 monthly. It might take you around 5 years to pay off, with total interest about $8,000. You consider a 60-month car loan at 7.54% for $10,000. Your monthly payment might drop to about $200, which feels easier, but over 5 years you pay roughly $1,600 in interest. This looks better, but if you extend the loan term beyond what you had, the total interest could still be high compared to paying off faster.

If you only lower your monthly payment but extend the loan, you might feel better month to month but owe more in the long run.

Other factors to consider

• Fees: Watch for origination fees or prepayment penalties. For example, a 3% fee on a $10,000 loan adds $300 upfront.
• Credit score: Applying for a loan can cause a small, temporary dip in your credit score.
• Discipline: Consolidation won’t help if you keep using credit cards and adding debt.
• Payment terms: Fixed payments are easier to budget than variable ones.

Also, consider your overall budget. A loan with a lower monthly payment might free up cash but increase total cost. On the other hand, a higher payment with a lower rate and shorter term saves money overall.

What you can do now

• List all your debts with balances, interest rates and monthly payments.
• Use a loan calculator to compare your current payments with a consolidation loan.
• Check for fees on new loans and penalties for paying off old debts early.
• Consider if you can pay off the consolidation loan faster than your old debts.
• Avoid adding new debt while paying off your consolidation loan.

Consolidating can be a useful tool. It may lower your total interest and simplify payments. But it can also just move debt around without saving money. Take time to compare your options and understand the costs before deciding.
