Debt Consolidation Calculator

Compare your current debt payments with a consolidation loan, including loan fees, payoff timing and total interest.

For multiple current debts, use a weighted average APR. If you do not know it, compare low and high APR scenarios instead of relying on one point estimate.

Method

The current-debt scenario is simulated month by month using the weighted APR and current monthly payment. The consolidation scenario uses the standard amortized loan payment formula, then adds any upfront fee to the cost comparison.

Example

If current debts total $18,000 at a weighted 21% APR with $650 monthly payments, compare that payoff path with an $18,000 consolidation loan at 10.5% over 4 years. The useful result is not only the new payment, but total interest plus any origination fee.

Common mistakes

Do not use a consolidation loan to free up credit cards and then rebuild balances. The estimate assumes the old debts are paid off and no new debt is added.

What to compare

A lower monthly payment is not automatically cheaper. A longer loan term can reduce monthly pressure while increasing total interest. Compare both the payment change and total interest plus fees.

Limitations

This calculator does not model credit approval, variable rates, balance-transfer rules, hardship plans, tax effects or changes in spending. It is not debt counseling or lending advice.
