Debt Consolidation Calculator
Determine whether debt consolidation is financially rewarding by comparing combined existing debts with a single consolidation loan accounting for fee-adjusted APR, monthly payment, and total lifetime interest.
Debt Consolidation Calculator
The Debt Consolidation Calculator can determine whether it is financially rewarding to consolidate debts by comparing the APR (Annual Percentage Rate) of the combined debts with that of the consolidation loan. APR is the fee-adjusted financial cost of a loan, providing a more accurate basis for loan comparisons. The calculated results will also display comparisons such as the monthly payment, payoff length, and total interest.
• Section 1: Enter your existing credit cards and loans with their current balances, payments, and APRs.
• Section 2: Enter your proposed consolidation loan terms (interest rate, duration, and origination fees) to calculate your net savings.

Existing Combined Debts vs. Consolidation LoanCost & Interest Comparison
Existing vs. Consolidation BreakdownWhen Does Debt Consolidation Make Financial Sense?
Debt consolidation merges multiple high-interest credit lines into a single installment loan with fixed monthly payments. Evaluating the fee-adjusted APR and total lifetime interest ensures refinancing saves money rather than extending debt.
Origination Fees & APR
Consolidation loans often charge upfront origination fees between 1% and 8%. Always compare the fee-adjusted APR rather than the nominal interest rate to verify that total finance charges are genuinely lower.
The Loan Term Trade-Off
Extending a loan term reduces your monthly payment, improving immediate cash flow. However, stretching repayment over too many years can result in paying more total interest despite a lower interest rate.
Credit Score Impact
Paying off credit card balances with a personal installment loan drastically lowers revolving credit utilization, often generating a substantial boost to your FICO credit score within 30 to 60 days.

Debt Consolidation Calculator — Frequently Asked Questions
Q1 What is fee-adjusted APR and why is it crucial for consolidation comparisons? ▾
Fee-adjusted APR includes both the nominal interest rate and any upfront origination points or closing fees spread across the life of the loan. Comparing fee-adjusted APRs ensures you see the true annualized borrowing cost rather than just the promotional interest rate.
Q2 When does consolidating debts save the most money? ▾
Debt consolidation provides maximum financial savings when you qualify for an interest rate significantly lower than your current weighted average APR, maintain a loan term shorter than or equal to your current payoff timeline, and keep origination fees low.
Q3 Can debt consolidation lower my monthly payments but increase total interest? ▾
Yes. If you consolidate into a long-term loan (such as extending 2 years of credit card debt over a 7-year personal loan), your monthly payment may decrease substantially, but the extended interest accrual over time can result in higher total lifetime finance charges.
Q4 How does debt consolidation affect my credit score? ▾
Paying off multiple revolving credit cards with a single fixed installment loan immediately drops your credit utilization ratio (which accounts for 30% of your FICO score), often providing a swift score boost within 1 to 2 billing cycles.
Q5 What types of debts can I consolidate? ▾
You can consolidate almost any unsecured debt, including high-APR credit cards, department store cards, medical bills, payday loans, and existing high-interest personal loans.
