Free Debt Consolidation Calculator

Debt consolidation is usually advertised around one number: a lower monthly payment. That number is real and it can genuinely help a tight budget. But a lower payment and a lower total cost are two different questions, and this page is built to answer both of them separately instead of letting one hide the other.

What Debt Consolidation Actually Is

Debt consolidation replaces several existing debts, such as credit cards or personal loans, with a single new loan. The new loan pays off the old balances, and you then make one payment on the new loan instead of several payments on the old ones. The balances have not disappeared. They have been reorganized under a new rate, a new term, and often a new fee.

Why Someone Would Consider It

People consolidate debt for a few common reasons: to simplify multiple payments into one, to try to lower the interest rate they're paying overall, or to lower the required monthly payment so it fits their budget more comfortably. Each of those goals is legitimate, but each one is measured differently, and improving one does not guarantee the others improve too.

To see how this works in practice, consider three debts: a $10,000 credit card at 17.99% APR with a $260 monthly payment, a $7,500 credit card at 19.99% APR with a $190 monthly payment, and a $6,500 debt at 18.99% APR with a $180 monthly payment. Together, that's $24,000 in debt and $630 in combined monthly payments.

The Weighted Average APR Explained

A simple average of 17.99%, 19.99%, and 18.99% would be about 18.99%, but that number ignores how much is owed at each rate. The balance-weighted average APR multiplies each balance by its own APR, adds those together, and divides by the total balance. For the example above, that works out to approximately 18.89% because the largest balance sits at the lowest of the three rates and pulls the average down more than the smaller, higher-rate balances pull it up.

The Current-Plan Baseline

Modeling each debt on its own, using its own balance, APR, and payment until it reaches $0, produces a current-plan baseline for the example above of about 65 months to pay everything off, roughly $13,056 in modeled interest, and roughly $37,056 in total modeled payments. That baseline is what any proposed consolidation loan is measured against.

A lower rate can help, but the rate alone does not determine whether consolidation lowers total cost. Loan fees, repayment term, payment amount, and how long the existing debts would otherwise remain outstanding all affect the comparison. The two scenarios below, using the same $24,000 in debts from above, show why.

Scenario One: Lower Payment and Lower Total Cost

Scenario Two: Lower Payment But Higher Total Cost

Why Both Scenarios Matter

Scenario Two is deliberately included because it's a common and easy-to-miss outcome. A bigger monthly payment reduction can come from stretching the term, not from a cheaper loan. If a result only showed "your payment drops by $157.89" without also showing that total cost rises by about $2,601, it would be misleading. That's why this calculator always reports the payment difference and the total cost difference as two separate results, never as a single combined verdict.

The interest rate changes how much interest accrues on the remaining balance each month. The term changes how many payments that interest and principal get spread across. A lower rate, by itself, tends to reduce both the payment and the total interest. A longer term, by itself, tends to reduce the payment but increase the total interest, because more months means more opportunities for interest to accrue before the balance reaches $0. Consolidation offers often change both the rate and the term at the same time, which is exactly why the two need to be evaluated together rather than assumed to move in the same direction.

Many personal consolidation loans include an origination fee, often expressed as a percentage of the loan amount. How that fee is handled changes the math in a specific way. If the fee is added to the loan balance, the loan principal increases by the fee amount, which means you also pay interest on the fee itself over the life of the loan. In the example above, a $1,200 fee financed into a $24,000 loan makes the actual borrowed amount $25,200, and the payment, interest, and total cost calculations all use that larger figure.

If the fee is paid upfront instead, the loan principal stays at the amount being consolidated, but the fee is still added once when comparing total cost, since it's still money spent to obtain the loan. Neither treatment allows the fee to be counted twice; the calculator applies it in exactly one place depending on which option is selected.

The interest rate and the APR are often confused, but they answer different questions. The interest rate is what's used to calculate interest on the outstanding balance and, therefore, the monthly payment. The APR is a broader measure of borrowing cost that can incorporate certain fees in addition to the interest rate, which is why a loan's APR is sometimes higher than its stated interest rate. This calculator uses the interest rate you enter to calculate the payment. If your lender also provided an APR, you can enter it in the optional field for reference, but it does not change the payment math.

Holding your entered term, fee, and fee treatment constant, there's a specific new loan interest rate at which the consolidation loan's modeled all-in cost would equal your current-plan baseline cost exactly. In the 60-month, 5%-financed-fee example above, that break-even rate works out to approximately 16.36%. Any rate below that, at the same term and fee, is estimated to cost less than the current baseline. Any rate above it is estimated to cost more. This number is a mathematical reference point calculated from your inputs, not a rate a lender has offered you or an estimate of what you would be approved for.

The current-plan baseline keeps every debt's payment fixed at the amount you entered for that debt, for as long as that debt has a balance. When a debt is paid off, its payment is not automatically redirected to your other debts to speed them up. That's a deliberate design choice: redirecting freed-up payments toward other debts is the core idea behind debt snowball and debt avalanche strategies, which belong to the Debt Payoff Calculator, not this page. Keeping the baseline fixed makes it a fair, consistent comparison point against the consolidation loan, which also has a single fixed payment for its entire term.

Consolidation is one of several ways people address multiple debts, and it isn't automatically the right fit for everyone. A personal consolidation loan replaces the debts with a single new loan at its own rate, term, and fee. A balance transfer credit card can offer a promotional rate for a limited time but usually charges a transfer fee and reverts to a standard APR once the promotion ends. A home equity loan or line of credit can offer a lower rate because it's secured by your home, but that also means your home is collateral, so it's not automatically the cheaper or safer choice once that risk is considered. Debt snowball and debt avalanche strategies keep your existing accounts open and change only the order and allocation of payments across them, without taking on new debt at all. None of these is universally best; each depends on the rates, fees, terms, and risks involved.

This calculator does not predict your credit score, does not estimate loan approval odds, and does not model debt settlement or credit counseling arrangements, since those involve negotiating with creditors rather than comparing loan math. It also does not account for late fees, penalty APRs, missed payments, or changes to a variable-rate loan after the fact. It compares the numbers you enter today under the assumptions you provide, nothing more.

A lower total cost is one useful outcome, but it isn't the only consideration. A higher payment that saves money over time still has to fit your monthly budget today. Before committing to any consolidation offer, it can help to check the new required payment against your actual monthly income and expenses using the Budget Calculator, and to model the proposed loan on its own using the Loan Calculator if you want to test different rates or terms independently of this comparison.

• Debt consolidation replaces existing debts with a new obligation. It does not erase the debt.
• A balance-weighted average APR, not a simple average, is the correct way to summarize multiple debts at different rates.
• A lower monthly payment and a lower total cost are separate results and should be evaluated separately.
• A lower payment can come from a longer term rather than a cheaper loan, and a longer term can raise total cost even when the payment falls.
• Origination fees change the math differently depending on whether they're financed into the loan or paid upfront, and either way should only be counted once.
• The break-even rate is a mathematical reference point based on your inputs, not a guaranteed or qualifying rate.
• This calculator does not roll a paid-off debt's payment into another debt. That belongs to the Debt Payoff Calculator.
• This calculator does not predict your credit score or your loan approval odds.

Educational estimate: CalculateThisWay compares current debts with a proposed consolidation loan using the balances, payments, rates, term, and fees entered. Actual repayment costs may differ because credit cards and lenders can use different interest calculations, fees, payment allocation methods, variable rates, promotional terms, lender disclosures, payment dates, and other account conditions. Results are for educational and planning purposes and are not a loan offer, approval estimate, debt-management recommendation, credit counseling, legal advice, or individualized financial advice.
