Debt Consolidation Savings Calculator

How it works

Consolidation rolls your balances into one new loan at a lower rate. Held over the same term, a lower rate means a smaller monthly payment, and since the balance and number of payments are unchanged, every dollar of that lower payment is interest you no longer pay. The calculator prices the same balance at both rates and multiplies the payment gap by the term:

With the defaults, $15,000 over 48 months costs about $473 a month at 22% but only $395 at 12%. That is roughly $78 a month less, and across all 48 payments it adds up to about $3,724 saved. The saving comes entirely from the lower rate, which is why keeping the term the same for both is essential to an honest comparison.

A worked example: $15,000 from 22% to 12%

Picture $15,000 spread across cards charging 22% APR. Roll it into a single consolidation loan at 12% and pay it off over 48 months, and you save $3,724 in interest overall.

The monthly side eases too. The 22% balance costs about $473 a month, while the 12% loan runs $395, a saving of $77.58 every single month. Same payoff timeline, a lower rate, and far less of each payment going to interest.

The wider the gap between your current rate and the new one, the more of each payment you keep in your own pocket. Enter your own balance, both rates, and payoff term to see what consolidating would actually save you.

Consolidation done right

• Do not stretch the term. A longer loan can lower the payment while raising total interest. To see the true saving, compare the new loan over the same months you would have paid anyway.
• Count the fees. Origination fees or balance-transfer charges eat into the saving. Our consolidation break-even calculator shows how long it takes to earn a fee back.
• Do not re-borrow. Consolidation frees up your old cards. Running them back up turns one manageable loan into a new pile of debt on top of it.

The rate is the whole game

Every dollar this calculator shows you saving comes from one thing: a lower interest rate over the same term. The balance does not change and the number of payments does not change, so the only lever is the rate. That makes one number the key to the whole decision, your current blended rate, the figure a new loan has to beat.

• Find your blended rate. If you are consolidating several balances, your effective rate is a balance-weighted average of them. A big balance at a high rate pulls it up more than a small one does.
• Beat it to save. Any consolidation rate below that blended figure produces a saving; the further below, the larger the payoff over the term.
• Mind the term. The saving here assumes the same payoff window. Stretch the term and a lower rate can still leave you paying more interest in total, which hides the real comparison.

So the honest test is simple: estimate the blended rate you pay now, compare it to the rate you have actually been offered, and hold the term steady while you do. If the new rate clears that bar by a meaningful margin, the saving is real. If it barely squeaks under, fees may swallow the difference, and consolidation may not be worth the paperwork.

The main ways to consolidate

Consolidation is a goal, not a single product, and the vehicle you use shapes both the rate and the risk. A few common routes are worth knowing before you commit, because the best one depends on your credit, your balance, and how fast you can repay.

• Personal loan. A fixed-rate installment loan with a set payoff date. Predictable and unsecured, it is the most common way to fold several card balances into one payment.
• Balance-transfer card. A promotional rate, often 0%, for a fixed window, usually with a one-time transfer fee. Excellent if you can clear the balance before the promo ends, costly if you cannot.
• Home equity loan or line. Typically the lowest rate because it is secured by your house, which is exactly the catch: miss payments and the collateral is your home, so the low rate carries real risk.

Whichever route you weigh, plug its rate and term into this calculator against your current blended rate to see the saving, then check the fees separately with our break-even calculator. A low headline rate is only a genuine bargain once its fees and its risks are counted alongside it, so read the whole offer before you move a balance. It also helps to run the numbers before you apply, not after.

Lenders set your rate once they see your credit, so treat any advertised figure as a best case and re-check the saving here with the actual offer in hand. A rate that looked like a bargain in the ad can shift once it is priced to your own profile.
