How this calculator works

Debt consolidation replaces several debts with one loan. The goal is usually a lower rate, a single repayment or a shorter payoff.

The calculator compares two paths:

If your current repayment does not cover the monthly interest, the current path never clears and the calculator says so instead of guessing.

Enter your own rates. Consolidation loans are priced on credit history and the lender's terms, so the result is an estimate.

Frequently asked questions

Does consolidation always save money?
No. A lower rate helps, but a longer term can raise total interest even when the repayment falls. Compare the total cost of credit on both paths before deciding.
What if my current repayment does not cover the interest?
Then the current balance never falls and that path never clears. The calculator reports no payoff time for the current path instead of returning a number.
Does a longer consolidation term lower my cost?
It lowers the monthly repayment but usually raises the total interest, because you pay interest for more months. A shorter term costs less overall but has a higher repayment.
Should I include all my debts?
Add up the balances you want to consolidate and use the average APR across them. Debts with much higher rates will pull the average up.
