Debt Consolidation Calculator

By the CalcMundi team · Updated October 22, 2026 · Formulas checked against standard financial math

List your current debts and the consolidation loan offer to see if it lowers your interest and your monthly payment.

When it helps

A consolidation loan pays off several debts, usually credit cards, and leaves one fixed payment. It is worth it when the new APR, including the origination fee, is clearly lower than what you pay today.

Example

Three cards totaling $12,000 at 21.5% to 28% APR, paying $375 a month, cost about $7,800 in interest. A 36-month loan at 11.5% with a 3% fee costs about $2,673, saving about $5,127, with a payment of $407.58.

Frequently asked questions

What is the risk?

Running the cards up again after consolidating. Consider lowering the limits or closing some cards.
