Debt Consolidation Calculator
Add each credit card balance and APR, then set a target consolidation loan APR and term to see how much monthly payment and total interest you could save.
Compare your cards with one loan
Compare fixed payments based on each card’s initial estimated minimum with a fixed-rate consolidation loan.
Card baseline: initial payment = min(balance + monthly interest, max($25, 1% of balance + monthly interest)). That payment is held constant until payoff, including a smaller final payment. Each card is simulated separately without rolling freed payments into other cards. Compare the sum of card interest with the amortized loan interest; longest card payoff is the baseline timeline. This is not a declining-minimum-payment model. Fees, rate changes, and new purchases are excluded.
Methodology and assumptions
Monthly payment = P × r ÷ [1 − (1 + r)^(−n)], where P is the loan amount, r is the annual rate divided by 1,200, and n is the number of monthly payments. At 0% APR, payment = P ÷ n. Total repaid = payment × n; total interest = total repaid − P.
This estimate treats your APR as a fixed nominal annual rate with monthly interest and payments at the end of each month. Fees, insurance, taxes, variable-rate changes, and extra payments are excluded unless a tool explicitly includes them. A disclosed APR can include fees and may differ from the contractual interest rate. Values are rounded for display only. Estimates are not lending offers.
Example: $10,000 at 15% for 36 months is approximately $346.65 per month, $2,479.52 in interest, and $12,479.52 repaid, assuming no fees.

For example only. Card payments are held fixed at the initial estimated minimum, not recalculated as balances fall. No new charges or loan fees are assumed. Real card minimums, APRs, and issuer terms vary. A consolidation offer is subject to lender eligibility and pricing.
How the savings estimate works
The "current path" assumes you pay only the typical monthly minimum on each card (the greater of $25 or 1% of the balance plus that month's interest) and never charge again. Real card minimums vary by issuer. The "consolidation path" assumes you pay off every card in full on day one using a fixed-rate personal loan at the APR and term you selected.
The gap between the two — often tens of thousands of dollars over the life of the debt — is the structural cost of revolving vs. installment debt. It's why debt consolidation is one of the most frequently used and most effective uses of a personal loan.
