How this debt consolidation calculator works
Current debts and minimum payments
Each debt accrues monthly interest at its entered APR divided by 12. Interest rounds half-up to cents. The entered monthly payment stays fixed, even if a lender's required minimum would decline. Payments stop when each balance reaches zero; there is no snowball or avalanche rollover. No new purchases, rate changes, promotional periods, late fees or prepayment penalties are included. A payment that does not cover monthly interest cannot produce a finite payoff estimate; we ask you to increase it. The current-debt projection is limited to 1,200 months.
Proposed APR versus interest rate
The new loan equals the sum of your current balances. Its origination fee is paid separately upfront. If you enter an interest rate excluding fees, the monthly payment before rounding is P × r / (1 − (1+r)^(−n)), where P is total debt, r is monthly interest and n is the term. At zero interest it is P / n.
For an APR that includes the origination fee, we first calculate the payment implied by the net amount financed P − fee and monthly APR. We then solve for the interest rate that amortizes the full principal at that payment. This assumes the entered fee is the only finance charge, equal monthly periods and the first payment one month later. It is an estimate, not a regulatory APR calculation. An APR too low to cover the fee with nonnegative interest is rejected.
The estimated interest rate is rounded to six decimal places. Monthly interest rounds half-up to cents. The regular new payment rounds up to cents, with at least one cent of principal in the first payment; the last payment settles the balance. Tiny balances may finish early. Your lender's dates, daily accrual and rounding may produce different results.
Payment relief, total savings and break-even
The monthly reduction compares actual first payments; current payments decline as individual debts finish. Total interest reduction excludes the new fee. Lifetime cost savings subtract both new interest and the origination fee from current interest. Total cash paid includes all principal, interest and the new upfront fee.
Lasting break-even is the first monthly point at which cumulative interest savings cover the origination fee and never fall below it again through both payoff dates. A temporary crossover that later disappears does not qualify. With no fee, break-even can be at the start if consolidation never costs more. If lifetime savings are negative, there is no lasting break-even. No discounting or investment return on payment differences is assumed.
Payment dates use the start-date anniversary, beginning one month later. Months without that day use their last day. Estimates do not account for weekends or holidays.
The CFPB's debt consolidation guidance explains that a longer repayment period can lower monthly payments while increasing total cost. These estimates help compare terms; they do not determine whether you qualify for a loan.
