A consolidation loan works best when you have high-interest debt and can lock in a lower rate
A consolidation loan is worth considering if you're paying more in interest across multiple debts than you would pay on a single loan. The math is straightforward: add up what you owe, find out what rate you'd get on a consolidation loan, and compare the total cost to what you're paying now. If the consolidation loan costs less overall, it's a reasonable move. If it costs the same or more, it isn't.
The catch is that a consolidation loan only saves money if three things are true: your new rate is lower than your current rates, you don't extend the repayment period so long that interest adds up again, and you stop using the credit cards or accounts you just paid off. Many people consolidate, then run up the same debts again while still paying the consolidation loan.
Whether consolidation makes sense also depends on what you're consolidating. Credit card debt at 18% to 24% is a strong candidate. Medical debt, personal loans, or store credit at lower rates may not be. A mortgage or car loan is almost never worth consolidating because those rates are already low.
Key Takeaways
- A consolidation loan saves money only if the new interest rate is lower than what you're currently paying across all your debts combined.
- Extending the repayment period can lower your monthly payment but will cost you more in total interest over time.
- Your credit score will drop slightly when you explore, but it usually recovers within a few months if you make on-time payments.
- Consolidation only works if you stop accumulating new debt on the accounts you've paid off.
How to calculate whether consolidation saves you money
Start by listing every debt you're considering consolidating: the balance, the interest rate, and the minimum monthly payment. Add up the balances to get your total debt. Then add up the monthly payments to see what you're paying now.
Next, get a rate quote from a lender for a consolidation loan in that amount. Most lenders will give you a rate estimate without a hard credit pull. Write down the rate, the monthly payment, and the loan term (usually 3 to 7 years). Use that monthly payment to calculate the total cost: multiply the monthly payment by the number of months in the loan term, then subtract the original balance. That number is the total interest you'll pay.
Do the same calculation for your current debts. If you're paying minimums on credit cards, you can estimate by dividing the total balance by the number of months you plan to pay. The goal is a rough comparison, not a precise forecast. If the consolidation loan's total interest is lower, consolidation makes financial sense. If it's higher or the same, it doesn't.
When your credit score will drop and recover
Your credit score will fall by 5 to 10 points when you explore for a consolidation loan, because the lender will run a hard inquiry and you'll have a new account on your report. That's normal and temporary.
The score usually recovers within three to six months if you make every payment on time. Some people see recovery faster. The key is consistency: one late payment can set you back months. If you're already behind on payments, consolidation won't help your score until you've made several on-time payments in a row on the new loan.
One benefit to your score comes later: if you pay off the credit cards you consolidated, your credit utilization (the percentage of available credit you're using) will drop. That can boost your score by 20 to 50 points over time, but only if you don't run the cards back up.
The difference between extending your payment period and lowering your rate
A consolidation loan can lower your monthly payment in two ways: by reducing your interest rate, or by spreading the debt over a longer period. These are not the same thing financially.
If you consolidate $15,000 in credit card debt at 20% into a 5-year loan at 10%, you save money on interest. If you consolidate the same $15,000 at 10% into a 7-year loan instead of 5 years, your monthly payment drops, but you pay more interest overall because you're paying for two extra years. The longer the loan, the more interest you pay, even at a lower rate.
When comparing offers, look at the total interest cost, not just the monthly payment. A lender might offer you a lower payment by stretching the loan to 7 years, but that could cost you hundreds more in interest. Ask the lender for the total interest amount upfront, and compare it to what you're paying now.
Situations where consolidation usually doesn't help
Consolidation doesn't make sense if you have very good credit and low-interest debt. If you're paying 6% on a personal loan and 7% on a car loan, a consolidation loan at 8% or 9% will cost you more, not less. The math has to work in your favor.
Consolidation also fails if you don't address the behavior that created the debt. If you ran up $20,000 in credit card debt and consolidate it into a personal loan, but then run up the credit cards again, you now have $20,000 in personal loan payments plus new credit card debt. You're worse off than before. Consolidation is a tool for people ready to stop borrowing, not a way to keep borrowing without consequences.
If you're behind on payments or in default, consolidation may not be available to you. Most lenders require a credit score of at least 580 to 620, and some require 650 or higher. If your score is lower, you may need to catch up on payments first, or look at other options like a debt management plan through a nonprofit credit counselor.
What happens to your old accounts after consolidation
When you consolidate, the old debts don't disappear—they're paid off by the new loan. The accounts themselves stay on your credit report, but they'll show a zero balance. You can leave them open or close them.
Closing them when ready might seem like a good idea, but it can hurt your credit score because it lowers your total available credit and raises your utilization percentage. Leaving them open is usually better for your score, as long as you don't run them back up. If you're worried about temptation, you can freeze the accounts or cut up the cards while keeping them open.
The old accounts will eventually fall off your credit report after seven years of inactivity. Until then, they'll show that you paid them off, which is good for your credit history.
Alternatives to consolidation when it doesn't make financial sense
If consolidation doesn't save you money, other options exist. A balance transfer credit card can move high-interest debt to a card with 0% interest for 6 to 21 months, depending on the offer. This works only if you can pay off the balance before the promotional period ends. After that, the rate jumps to the card's regular APR, which is often higher than a consolidation loan.
A debt management plan through a nonprofit credit counselor can lower your interest rates without a new loan. The counselor negotiates with your creditors to reduce rates and create a repayment schedule, usually over three to five years. This doesn't require a credit pull and won't lower your score as much as a consolidation loan, but it does require you to close the accounts you're paying through the plan.
If your debt is very high relative to your income, you might also explore whether you're a candidate for bankruptcy. This is a last resort and has serious long-term credit consequences, but it can eliminate debt entirely rather than just reorganizing it. A bankruptcy attorney can tell you whether it's an option in your situation.
Frequently Asked Questions
Will consolidation hurt my credit score?
Yes, but temporarily. Your score will drop 5 to 10 points when you explore because of the hard inquiry and new account. It usually recovers within three to six months if you make on-time payments. If you pay off credit cards after consolidating, your score may improve beyond where it started.
Can I consolidate federal student loans?
Federal student loans have their own consolidation program through the Department of Education, separate from personal consolidation loans. Federal consolidation doesn't require a credit check and preserves income-driven repayment options. A personal consolidation loan is not recommended for federal student loans because you lose those protections.
What if I can't afford the monthly payment on a consolidation loan?
If the payment is too high, you can ask the lender to extend the term, which lowers the payment but increases total interest. Alternatively, you might not consolidate at all and instead work with a credit counselor on a debt management plan, which often has lower monthly payments than consolidation.
Should I close my credit cards after consolidating them?
Closing them when ready can hurt your credit score by lowering available credit. It's usually better to leave them open with a zero balance. If you're concerned about running them back up, freeze the accounts or cut up the cards while keeping them open.
How long does a consolidation loan take to process?
Most lenders fund consolidation loans within 3 to 10 business days after approval. Some offer faster funding for an extra fee. Once funded, the lender pays off your old debts directly, and you begin making payments on the new loan.
