Debt Consolidation Calculator
Combine two balances and entered fees, calculate a balance-weighted starting APR, and estimate payoff under one planned payment. The consolidation bridge shows how fees increase principal before payment and interest determine the outcome.

Debt-to-consolidation balance bridge
Debt-to-consolidation balance bridgeTwo debts and entered fees reconcile to one modeled opening balance before payment, rate, and payoff are evaluated.

Monthly schedule and annual summary
How to use Debt Consolidation Calculator
- Record current payoff balances and APRs from recent statements.
- Add origination, transfer, closing, or membership fees that become part of cost.
- Compare the modeled consolidated path with a separate-debt payoff schedule using the same monthly cash budget.
Calculator guide
Understanding Debt Consolidation Calculator
Debt consolidation replaces several obligations with one modeled balance, but a lower payment is not automatically a lower cost. Fees, the new rate, term, and protections must be reconciled against keeping debts separate.
Calculation method
How the calculation works
Combine the balances and entered fees, estimate a balance-weighted APR, and model the planned payment against the consolidated amount. Add both balances and fees. Weight each existing APR by its balance for a comparison rate, then amortize the combined modeled balance using the planned payment.

The advertised APR is only one line of the decision.
Worked situations
Practical examples
- $12,000 at 22% plus $18,000 at 11% has a weighted starting APR near 15.4%.
- Adding a $750 fee creates a $30,750 modeled opening balance.
- A lower new payment can still cost more if it extends repayment.
Better inputs
Useful tips
- Use the offered consolidation APR rather than the weighted old APR when evaluating an actual quote.
- Keep promotional-rate expiration and transfer-fee dates visible.
- Do not reopen paid revolving balances unless the budget includes that risk.
Before relying on the result
Limitations and common mistakes
- The displayed blended APR describes existing balances; it is not a lender quote.
- Different minimum payments, promotional periods, daily interest, late fees, and changing rates are simplified.
- Credit impact, collateral, tax treatment, and lost borrower protections are excluded.
Reference
Key terms
- Weighted APR
- Balance-weighted average of the entered debt rates.
- Consolidation fee
- Entered cost added to the modeled opening balance.
- Term extension
- Repayment stretched across more months, often lowering payment but increasing total interest.
- Unsecured debt
- Debt not backed by pledged collateral.
Important note
Calculated from the entered values and stated financial terms. It is not a product quote, lending decision, tax filing, or investment recommendation.
Frequently asked questions
Is the weighted APR the rate I should accept?
No. It is a comparison benchmark for the entered debts; evaluate the actual offered APR and fees.
Why add fees to the balance?
Fees financed into the new obligation earn interest and affect payoff.
Can consolidation improve cash flow but worsen total cost?
Yes. A longer term can reduce the monthly payment while increasing lifetime interest.
Does this choose snowball or avalanche order?
No. It models one combined balance rather than separate payoff priority.
