Debt Consolidation Loan Calculator

A debt consolidation loan does one specific job. It replaces several card balances with a single new loan that has a fixed amount, a fixed rate, and a fixed end date. Instead of juggling minimum payments across cards while interest accrues at card rates, you make one payment each month and the balance falls on a schedule you can read in advance. That clarity is the real product. The interest saving, where it exists, comes from moving the balance to a lower rate and then actually paying it off on the schedule the loan sets. This page models that single job and nothing else. It does not compare loan types against each other, and it does not tell you which lender or product to pick. It shows what one loan costs at the amount, rate, and term you enter, so you can judge an offer with both eyes open.

Start with the tool above. Click the Consolidation variation button in the calculator and it loads a hypothetical $25,000 amount at a hypothetical 11.2 percent rate. That is the worked example this page uses throughout, and every figure tied to it is hypothetical and shown only to teach the comparison. From there, replace the amount with your own total card balance, enter the rate on an offer you have actually received, and test the term in months. The two numbers to hold side by side are the monthly payment and the total interest. The payment tells you whether the plan fits your month. The total interest tells you what the plan costs. Offers are usually sold on the first number. Sound decisions weigh the second number at least as heavily, because a small payment stretched over many months can quietly cost more than a larger payment finished sooner.

Keep the scope of the model in mind as you read. This calculator prices one new loan replacing card balances. It assumes the rate stays fixed, the payment arrives every month, and no new card charges appear after the loan is funded. Real life can break each of those assumptions, which is why the warnings later on this page matter as much as the arithmetic. If you want to compare consolidation against other payoff methods or loan types before you borrow, read the debt consolidation cost guide alongside this page, run the same balance through the credit card payoff calculator, and compare the general loan math on the personal loan calculator. If you are weighing payoff order across several debts without a new loan, the debt snowball vs avalanche calculator covers that choice. Each tool answers a different question. Use the one that matches the decision in front of you.

A consolidation loan only earns its place if it beats the path you are already on. The table below holds the hypothetical balance steady at a hypothetical $25,000 and compares the loan terms against keeping that balance on a card at a hypothetical 22.99 percent rate. Every rate and dollar figure is hypothetical. The card rows assume you pay a fixed amount each month, either the hypothetical $546.06 that matches the 60 month loan payment or the hypothetical $820.84 that matches the 36 month loan payment, with no new charges added.

Two comparisons in that table deserve your attention. First, at the identical hypothetical $546.06 monthly payment, the 60 month consolidation loan costs a hypothetical $7,763.45 in interest against a hypothetical $35,328.59 on the card path, a hypothetical saving of $27,565.14, and it clears the debt 51 months sooner. The rate gap does the work even when the payment does not change. Second, the 36 month loan at a hypothetical $820.84 saves more than the 60 month loan does, because it pairs the lower rate with a shorter life. Paying the card at that same hypothetical $820.84 still costs a hypothetical $12,885.84 in interest over 47 months, well above the hypothetical $4,550.16 on the 36 month loan. The lesson cuts both ways. Consolidation helps most when the new rate is materially lower and the term stays as short as the budget allows. It helps least when a lower rate is used as permission to stretch the debt across the longest term on offer.

That second point is the term trap, and it is the most expensive mistake on this page. The hypothetical 60 month interest of $7,763.45 against the hypothetical 36 month interest of $4,550.16 means the longer term hands back a hypothetical $3,213.29 of the saving the rate gap created. Borrowers fall into the trap because the payment is the number they feel each month, while total interest is a number they only feel at the end. Reverse the habit while you compare offers. Cover the payment column, rank the terms by total interest, then uncover the payments and ask honestly which of the low cost terms you can carry in a difficult month. If the shortest term payment would force you back onto a card to cover groceries or rent, it is not the cheapest option in practice. A missed payment and fresh card debt cost more than the interest you were trying to save. Choose the shortest term you can sustain on your worst regular month, not the shortest term you can sustain on your best one.

The calculator prices interest only, and real offers can add other charges. The charge to ask about first is an origination fee, a lender fee for setting up the loan. Depending on the agreement, the fee may be deducted from the money sent to pay off your cards, which leaves you short of a full payoff, or added to your balance, which means you owe more than the card balances you replaced from the first day. Either method raises the true cost above the interest figure the calculator shows. Keep the discussion in dollars with each lender: ask for the fee amount, ask whether it is deducted or added, and ask for the APR. The APR states the yearly cost with the interest rate and certain fees counted together, so it ranks fee carrying offers more honestly than the interest rate alone. If a fee is added to the balance, enter the full amount you will owe, balance plus fee, as the amount in the calculator. The payment and interest it returns will then reflect what you actually repay.

The second risk is what stands behind the loan. Most consolidation loans are unsecured, meaning no property backs the promise to repay, and the lender prices that risk into the rate and fees. Secured borrowing, where a home or a vehicle stands behind the loan, can carry a lower rate because the lender can claim the property on default. Trading unsecured card debt for debt secured by your home is a serious step and it should never be taken lightly to chase a lower payment. Missed card payments damage credit. Missed payments on a home secured loan can cost the home. For most households consolidating card balances, an unsecured loan that fits the budget is the proportionate tool, even at a higher rate than a secured offer. If a lender presents a secured offer for card debt, slow down, read the default terms in full, and weigh the property at risk against the interest saved before you sign anything.

The third risk is not in the contract at all. Consolidation clears the cards, and cleared cards invite spending. The household then carries the new loan payment plus fresh card balances, which is a worse position than the one the loan was meant to fix. Treat the funding day as a behaviour change, not just a balance change. Lock or close the paid off cards, remove stored card details from shopping accounts, set the loan payment to leave your account automatically the day after payday, and check your total debt, loan balance plus any card balances, on the same day each month. The total should fall every month. The month it stops falling is the month to fix spending, and no rate negotiation will fix it for you. If you know the cards will be used again, a consolidation loan adds a payment without removing the problem. In that case a direct payoff plan, such as the methods compared in the snowball and avalanche guide, may serve you better than new borrowing.

1. Choosing the term by payment alone. The longest term shows the smallest payment and the largest interest bill. In the hypothetical example, stretching from 36 to 60 months adds a hypothetical $3,213.29 in interest. Rank terms by total interest first, then test the payment against your budget.
2. Comparing interest rates and ignoring the APR. Fees sit outside the interest rate, so two offers with the same rate can cost different amounts. Compare APRs and total amounts repaid, and enter any fee added to the balance into the calculator amount.
3. Borrowing more than the balances being replaced. Approval is a ceiling, not a target. Every extra amount borrowed earns interest for the full term. Borrow the amount that clears the cards you intend to close out, no more.
4. Leaving the paid off cards open for just in case. Open, empty cards are how consolidation debt doubles. Lock or close them on funding day, before the first loan payment is even due.
5. Securing card debt with a home to get a lower rate. A lower rate is not worth turning unsecured balances into debt that can claim your house. Read what default means before you trade flexibility for a rate.
6. Assuming the calculator result includes every charge. The tool prices interest on the amount you enter. Late fees, optional products, and origination fees live in the agreement, not in the formula. Read the agreement and add its charges to your own comparison.
7. Skipping the card path comparison. If you can sustain a high fixed payment, staying on a card at a hypothetical high rate may still cost more than a loan, but the gap depends on your real rates. Run the balance through the card payoff calculator so the decision rests on your numbers.

Work in a fixed order and do not let an advertisement reorder it for you. First, add up the card balances you would replace and use that total, and nothing above it, as the amount. Second, enter the rate from a written offer, not a headline rate, and generate all three terms, 36, 48, and 60 months, on that same amount and rate. Third, write down the payment and the total interest for each term, plus the fee facts for the offer: the fee amount, whether it is deducted or added, whether a prepayment penalty exists, and the APR. Fourth, take the shortest term whose payment still leaves room in your monthly budget for housing, food, transport, minimum payments on anything not being consolidated, and a small margin for the irregular expenses that arrive every year. That term is your candidate. The longest term is only the right answer when the shorter payments genuinely do not fit, and even then it should be paired with a plan to send extra toward principal when good months allow, provided the agreement has no prepayment penalty.

Before you sign, run two honesty checks. The first is the total debt check. Picture the loan funded and the cards paid. Write down the single monthly total you will pay across the loan and any remaining debts, and confirm it is lower than what you pay now at a pace you can sustain. If the new total only works by assuming overtime, a bonus, or a perfect month, the term is too short or the amount is too large, and waiting or paying cards down first may be the stronger move. The second is the behaviour check. Decide today, in writing, what happens to each paid off card, which day the loan payment leaves your account, and which day each month you will total your remaining debt. Households that finish consolidation loans tend to share those three habits. Households that return with larger balances tend to have skipped them and trusted the lower rate to do work that only behaviour can do. The calculator above gives you the cost of each term in clean numbers. The choice that saves money is the shortest term on that list that your real budget and your real habits can carry to the final payment without reopening the cards along the way.
