Does Debt Consolidation Actually Save Money?

Debt consolidation promises simplicity — one payment instead of many. But simplicity alone doesn't save money. The real question is whether a consolidation loan at a lower rate reduces your total interest without extending your payoff timeline so far that you pay more overall.

This calculator compares two paths side by side: continuing to pay your debts separately at their current rates, versus rolling them into a single installment loan. You'll see total interest, payoff timeline, and monthly payment for each scenario.

Consolidation works best when you're consolidating high-APR credit card debt into a lower-rate personal loan and you commit to not running up new balances. If you consolidate and then charge more on your cards, you'll end up with more debt, not less.

Before consolidating, also run the Debt Avalanche vs Snowball calculator. Sometimes directing extra payments using avalanche strategy beats consolidation — especially if your highest-APR debts are small and can be eliminated quickly without a new loan.

How These Calculations Work

Transparent methodology — no black boxes. Here's exactly what happens when you use this calculator.

  1. 1

    Enter each current debt: balance, APR, and monthly payment.

  2. 2

    Enter the proposed consolidation loan APR and term.

  3. 3

    We simulate paying each debt independently vs one consolidated loan.

  4. 4

    Compare total interest, payoff dates, and single consolidated payment.

  5. 5

    Review whether consolidation actually reduces total borrowing cost.

Frequently Asked Questions

Consolidation saves when the new loan's APR is lower than the weighted average of your current debts AND you don't extend the term so much that total interest rises.
