Debt Consolidation Calculator is a free, independent tool that compares paying off multiple debts separately against consolidating them into a single loan, so you can see the real numbers before applying for anything.
You enter each of your current debts (balance, interest rate, minimum payment), and the tool calculates how long each would take to pay off and the total interest you'd pay using standard amortization math. It then compares that against a hypothetical consolidation loan at the rate and term you specify, using the same amortization formula lenders use to calculate installment loan payments. The result shows your weighted average current rate versus the consolidation rate, total interest saved (or lost), and the change in your monthly payment.
This tool does not constitute financial advice, and it is not a loan offer or pre-approval. Actual consolidation loan rates depend on your credit score, income, debt-to-income ratio, and the specific lender — they can differ meaningfully from the rate you enter here. Before consolidating, get pre-qualified quotes from multiple lenders (which typically don't affect your credit score) and confirm there are no origination fees or prepayment penalties that would change the math.
