Debt Consolidation Calculator: Compare Monthly Payments and Total Interest

Having several debts at the same time can make it difficult to see how much you are really paying each month.
You may have two credit cards, a personal loan, and another balance with different interest rates and payment dates. Looking at each account separately tells you what you owe, but it does not always show what those debts are costing you as a group.
A debt consolidation calculator gives you a simpler way to compare the numbers.
Instead of looking only at the new monthly payment, you can compare the balance, interest rate, repayment term, and total interest of a potential consolidation loan with your existing debts.
You can use the Debt Consolidation Calculator on LoanCalcCenter to estimate the numbers before deciding whether debt consolidation makes sense for you.
What Is Debt Consolidation?
Debt consolidation means combining multiple debts into one new loan or payment arrangement.
For example, you might have:
| Debt | Balance | APR | Monthly Payment |
|---|---|---|---|
| Credit Card A | $5,000 | 24.99% | $150 |
| Credit Card B | $3,500 | 21.99% | $110 |
| Personal Loan | $6,500 | 13.50% | $220 |
| Total | $15,000 | — | $480 |
A consolidation loan could potentially replace those three accounts with one $15,000 loan.
The new loan may have a lower interest rate, but that does not automatically mean it will cost less overall. The loan term, fees, and repayment schedule all matter.
This is why a debt consolidation loan payment calculator is useful. It lets you compare the complete repayment picture instead of focusing on one number.
How a Debt Consolidation Calculator Works
A debt consolidation calculator uses information about your current debt and a potential new loan to estimate the repayment cost.
The most important inputs are usually:
- Total debt balance
- Interest rate or APR
- Monthly payment
- New consolidation loan rate
- New loan term
The result can show an estimated monthly payment and the total amount that may be paid over the loan term.
That makes it easier to calculate a debt consolidation monthly payment and compare it with what you are currently paying.

A Lower Monthly Payment Does Not Always Mean Lower Cost
This is one of the easiest mistakes to make when comparing debt consolidation loans.
Suppose you currently pay $480 per month across several accounts. A new consolidation loan reduces the payment to $325.
That looks better from a monthly budget perspective.
But suppose the existing debt would have been paid off in three years while the new consolidation loan lasts five years.
Your monthly payment is lower, but you are making payments for an additional two years.
The important comparison is therefore:
Monthly payment + loan term + total interest
not just the monthly payment.
