How the comparison works

For your current debts, the calculator simulates each balance month by month at its APR and payment until it reaches zero, and adds up the interest. For the new loan, it grosses up the balance for any origination fee (a 5% fee on $16,000 means borrowing $16,842 to net $16,000) and uses the standard loan payment formula.

Worked example

DebtBalanceAPRPaymentPayoff timeInterest
Card 1$8,00024%$2504 yr 4 mo$4,899
Card 2$5,00021%$1504 yr 3 mo$2,570
Card 3$3,00028%$1004 yr 5 mo$2,220

Total now: $500 a month and $9,688 in interest. A 48-month loan at 12% with no fee: $421.34 a month and $4,224 in interest, a saving of $5,464.

When consolidation does not help

Other options

A 0% balance transfer can be cheaper for balances you can clear in the intro period. Nonprofit credit counseling agencies offer debt management plans that may lower card APRs without a new loan.

Example rates are for comparison only, not offers or current quotes. Your rate depends on credit, loan-to-value and lender.

Frequently asked questions

Does debt consolidation save money?

Only if the new APR, including fees, is lower than what you pay now and you do not stretch the term so far that total interest rises.

Does debt consolidation hurt your credit?

A new application causes a hard inquiry and a new account, which can dip scores briefly. Lower card utilization can help over time.

What is a good rate for a debt consolidation loan?

One clearly below your current average APR. Compare total cost in this calculator rather than the rate alone.
