What Is Debt Consolidation?
Debt consolidation replaces multiple debts with a single loan — usually at a lower weighted interest rate. It simplifies payments to one bill, but only saves money if the new rate and term genuinely reduce total interest.
The calculator compares your current debts (interest paid at your minimums) with a consolidation loan at the rate and term you enter, showing the difference in payments and total interest.
The Math
If the consolidation rate is below the weighted APR and the term is not excessively long, consolidation usually wins. Extending the term can make it lose despite a lower rate.

Frequently Asked Questions
When does debt consolidation make sense?
When the new rate is lower than your weighted APR and you do not stretch the term so far that interest grows anyway.
How is the weighted APR calculated?
Σ(balance × APR) ÷ Σ(balance) — the calculator shows it.
Does consolidation hurt my credit?
The loan application causes a small temporary dip; closing old accounts can affect history and utilization — weigh both.
What if I consolidate and keep using the cards?
The math only works if the cards stay empty. Consolidation with continued spending recreates the debt.
Is a consolidation loan better than a balance transfer?
It depends on the rates and fees — compare both offers with the respective calculators.
