Calculator

Debt Consolidation Calculator

Calculates current payoff time from total debt to consolidate, current blended annual rate, current monthly payment. Defaults are filled in so you can review a working example before changing inputs.

USD

Current total balance across the debts being compared.

%

User-entered weighted or approximate annual rate for the current debts.

USD

Total amount currently paid each month toward the debts.

%

User-entered rate for the proposed consolidation loan.

months

Whole number of monthly payments for the proposed loan.

%

User-entered fee added to the new amount financed. Enter 0 if there is no fee.

What the result means

Consolidation helps when the new loan's interest rate is lower than the weighted average of your current debts, and when you do not extend the term so long that the lower payment costs more interest overall. Compare both the monthly payment and the total interest: a smaller payment is not a saving if you pay more in the long run.

Formula

Debt consolidation replaces several balances with one new loan. The new monthly payment uses the standard loan payment formula: payment = P x r / (1 - (1 + r)^-n), where P is the total balance, r is the monthly interest rate (annual rate / 12), and n is the number of months. Your savings is the total interest on the old debts minus the total interest on the consolidation loan.

  • Consolidation combines multiple balances into one loan with a single payment, ideally at a lower interest rate than the debts it replaces.
  • It saves money only if the new rate beats the weighted average rate of your existing debts. Compare total interest, not just the monthly payment.
  • A longer loan term lowers the monthly payment but increases total interest; a shorter term does the opposite. Choose the shortest term you can comfortably afford.
  • Watch for origination fees, balance-transfer fees, or prepayment penalties, which reduce or erase the savings. Include them when comparing offers.
  • Consolidation does not reduce what you owe; it restructures it. Pairing it with a plan to stop adding new debt is what makes it effective.

Inputs

Enter each current debt's balance and interest rate, then the consolidation loan's interest rate and term. The calculator totals your balances, computes the single new payment, and compares the total interest you would pay before and after. A lower rate or a shorter term reduces total interest, while a longer term lowers the monthly payment but can raise total interest.

Example

Suppose you owe $8,000 on a card at 22% and $4,000 on another at 18%. Consolidating the $12,000 into a 5-year loan at 11% gives a monthly payment of about $261 and far less interest than the cards would charge, since the rate drops sharply. Stretching the same loan to 7 years lowers the payment but adds interest overall.

FAQ

How does debt consolidation work?

It combines several debts into a single new loan with one monthly payment, ideally at a lower interest rate. You use the consolidation loan to pay off the old balances, then repay the one loan over a set term.

Will consolidating my debt save money?

It saves money if the consolidation loan's interest rate is lower than the average rate on your current debts and you do not stretch the term too long. Compare total interest before and after, including any fees.

Does debt consolidation lower my monthly payment?

Often yes, because a lower rate or a longer term reduces the payment. But a longer term can mean more total interest, so a lower payment does not always mean a lower overall cost.

What is a good interest rate for a consolidation loan?

A good rate is one clearly below the weighted average rate of the debts you are consolidating. If your cards charge 20% or more, a consolidation loan in the low double digits or single digits can save a lot.

Does debt consolidation hurt your credit?

Opening a new loan can cause a small, temporary dip from the hard inquiry, but paying down balances and making on-time payments usually helps your credit over time. The calculator covers the math, not the credit impact.

Should I consolidate or pay debts off individually?

Consolidate if you can get a meaningfully lower rate and will not run the balances back up. If you can pay the debts off quickly or cannot get a better rate, focusing extra payments on the highest-rate debt may cost less.
