Debt Consolidation Calculator

This calculator answers one question honestly: is consolidating worth it? It works out the real APR of the debts you hold now, then the real APR of the consolidation loan after the fee is counted, and compares them. Advertised rates flatter loans that carry upfront costs, so a fee-adjusted comparison is the only fair one.

On the default figures, three debts totalling $24,000 carry a blended APR of 18.92%. A $25,000 loan at 10.99% over five years with a 5% fee has a real APR of 13.25%, so consolidating saves money, roughly $4,100 over the life of the debt, and it cuts the monthly payment from $630 to $543.44.

What debt consolidation is

Debt consolidation is a form of restructuring that rolls several debts into one. People do it for two reasons: to lower the interest rate, or to lower the monthly payment. A well-chosen loan does both. A third reason is administrative: one payment on one date instead of juggling five, which removes a whole category of missed-payment risk.

Almost every loan carries upfront costs, so the real cost of borrowing sits above the advertised rate. That gap is what this calculator exists to expose, because a 10.99% loan with a 5% fee is not a 10.99% loan.

Where the money comes from

Consolidation funds are either secured or unsecured, and that choice drives the rate.

Secured sources include home equity loans, home equity lines of credit, and cash-out refinances. Because property backs the debt, lenders carry less risk and charge less for it. Our Home Equity Loan Calculator and HELOC Calculator price those directly.

Unsecured sources include personal loans and balance-transfer credit cards. Rates run higher and limits lower, because there is no collateral to seize.

The trade deserves stating plainly. Moving credit card debt onto your house converts an obligation you could default on, painfully but survivably, into one that can cost you the roof. The lower rate is real, and so is that risk.

Why the fee decides it

Fees and points are the second-largest cost in most loans and the one people discount. Since the entire purpose of consolidating is to lower the cost of debt, a heavy fee can undo the benefit before you make a single payment.

The default case shows the mechanics. A 5% fee on $25,000 is $1,250, leaving $23,750 of usable proceeds against a $24,000 balance, so you must find $250 to close the gap. Even so, the real APR lands at 13.25%, comfortably under the 18.92% you are escaping.

Push that fee to 15% and the picture inverts. The proceeds fall well short of the balance, the real APR climbs above what the existing debts charge, and the verdict turns red. Same loan, same headline rate, opposite answer, which is precisely why APR rather than the advertised rate is the number to compare.

What the comparison assumes

The existing-debt column assumes you keep paying the same total each month until everything clears, rolling each cleared minimum onto the highest-rate debt still open. That matters: on the defaults it produces 59 months rather than the 65 you would get by letting each payment simply stop when its own debt ends.

It is also the fair comparison. The consolidation loan takes a fixed payment for a fixed term, so the alternative should be a disciplined repayment of the same debts, not a drifting one. If you would not actually keep paying $630 a month, the existing column understates what your debts really cost, and consolidation looks better than it is.

The term matters as much as the rate

Stretching repayment lowers the monthly payment and can raise total interest even at a lower rate. A five-year consolidation of debts that would have cleared sooner buys breathing room at a price.

Here the two effects roughly cancel: 60 months at 10.99% costs $7,606 in interest against $12,963 across 59 months at the existing rates, so the lower rate more than covers the extra month. Change the term to seven years and the monthly payment falls further while the interest climbs. Test both, and judge on total cost rather than the payment alone.

What it does to your credit score

The effect runs in both directions, and the net result depends on the route you take.

Applying for new credit triggers a hard inquiry, worth a few points, and opening a new account lowers the average age of your accounts. Both effects fade within months of on-time payments.

Working the other way is utilisation, the share of available credit you are using, which is one of the heaviest factors in most scoring models. Paying off cards with a personal loan drops card utilisation towards zero while the new balance sits in an instalment account, where balances are weighted far less. That combination often lifts the score within a couple of cycles.

Two things spoil it. Closing the paid-off cards removes their limits from the calculation and can push utilisation straight back up, so leaving them open and unused is usually better. And running the balances up again leaves you with the loan and the cards, which is how consolidation turns into more debt rather than less.

The balance transfer alternative

For smaller balances, a 0% balance transfer card often beats a consolidation loan outright. Introductory periods run 6 to 21 months, and during that window every dollar reduces the principal instead of servicing interest. Transfer fees of 3% to 4% are typically lower than loan origination fees, and there is no term to stretch.

The limits are real, though. Card limits rarely stretch to five-figure balances, approval needs decent credit, and anything still outstanding when the promotional period ends reverts to a standard card rate that is usually worse than the loan you passed up. It works when you can genuinely clear the balance inside the window; it is a trap when you cannot.

Consolidation is not a fix for the cause

A consolidation loan changes the terms of a debt. It does not change what created the debt, and if the underlying pattern continues, the cleared cards refill while the loan payment sits alongside them.

For many people the real fix is a change in habits: spending less, saving more, learning to live below their means. For others it is genuinely an income problem that no restructuring can solve. Either way, a written budget is the practical first step, before the question of consolidating even arises. Our Budget Calculator is a reasonable place to start, and the Debt Payoff Calculator shows what a disciplined repayment of the existing debts achieves with no new borrowing at all.

Worth knowing too: consolidating is rarely quick. Reputable routes involve assessing your finances properly, sometimes with a credit counsellor, and that takes time. Be wary of anything promising otherwise, particularly debt settlement firms that charge heavy fees, tell you to stop paying creditors, and leave lasting damage on your file.

How this calculator works

For your existing debts it runs each one forward month by month at its own rate, applying the minimums first and directing anything spare at the highest-rate balance. From the resulting payment stream it solves for the discount rate that returns the original balance, which is the true blended APR rather than a weighted average of the quoted rates.

For the consolidation loan it calculates the payment with the standard amortisation formula, subtracts the fee from the proceeds, then solves for the rate that discounts those payments back to what you actually receive. That is the real APR, and comparing the two is the whole exercise. To price a single replacement loan in more detail, see the Personal Loan Calculator.
