What Debt Consolidation Calculator does and how it behaves

Separate balances can hide whether consolidation improves the overall payoff. Enter each debt's balance, APR, and monthly payment, then describe the proposed replacement loan using its APR, term, and applicable fee. The calculator contrasts monthly payments, projected interest, and the time required for savings to recover the consolidation cost. The common surprise is that a lower required payment does not necessarily reduce total cost. Extending repayment can increase interest even when the new APR is lower.

How the result is produced

1

Existing-debt baseline

The calculator treats the entered debts as the baseline scenario. Their balances form the amount being consolidated, while each debt's APR and payment determine its projected payoff and remaining interest. It also totals the existing monthly payments. This preserves the effect of different rates rather than replacing them with a simple unweighted average.

Loan comparison

The proposed loan is evaluated over its stated term using the consolidation APR and financed balance. Its payment and projected interest are compared with the existing-debt totals. Monthly savings are the difference between the two payment amounts. When an upfront fee is entered, the breakeven timeline indicates how long those monthly savings take to offset that cost.

Good uses

  • Comparing a lender's consolidation offer with the expected cost of continuing current debt payments.
  • Checking whether a lower consolidation payment comes mainly from a lower APR or from a longer repayment term.
  • Estimating how long monthly payment savings would take to recover an origination or consolidation fee.

Limits and checks

  • The result assumes the entered APRs and payments remain unchanged; variable rates or changing payments can produce different payoff costs.
  • Monthly savings describe cash flow, not necessarily economic savings. A smaller payment can accompany a longer term and greater total interest.
  • The comparison does not account for missed-payment charges, prepayment penalties, optional insurance, taxes, or fees that are not entered.

Common questions

Does a lower consolidation APR guarantee lower total interest?

No. The repayment term also matters. A lower rate applied for substantially longer can still produce more total interest than the existing debts. Compare the total-interest result as well as the monthly payment, and confirm that every lender fee is represented before treating the calculated difference as savings.

Can this calculator tell me whether I will qualify for the loan?

No. It compares the figures you enter and does not predict approval, the rate a lender will offer, or whether proceeds will cover every debt. Use an actual loan disclosure for the proposed APR, term, amount, and fees. Credit underwriting and lender eligibility decisions remain outside this calculation.
