A finance number becomes easier to trust when you can trace it back to the inputs. Debt Consolidation Calculator summarizes multiple debts, their APRs, minimum payments, and the entered monthly debt budget for avalanche, snowball, or general payoff planning.

What this calculator does

Debt Consolidation Calculator summarizes multiple debts, their APRs, minimum payments, and the entered monthly debt budget for avalanche, snowball, or general payoff planning. The form asks for current debt balances, current aprs (%), consolidation loan apr, consolidation loan term and origination fee. The result should therefore be read as a calculation from those displayed assumptions, not as live market, lender, tax, or government-program data unless the page explicitly supplies such a feed.

How to use it

Enter Current debt balances, Current APRs (%), Consolidation loan APR, Consolidation loan term and Origination fee. Keep monetary inputs in one currency; the currency selector formats results and does not convert exchange rates. Enter rates and percentages on the scale shown by the field label; do not silently switch between a decimal and a percent. Keep time values in the period shown on the form so a monthly figure is not accidentally entered as an annual one or vice versa. Before calculating, recheck Current debt balances, Current APRs (%), Consolidation loan APR against the source values you intend to model. If a default value is already filled in, confirm that it matches the scenario you actually want to test rather than assuming the preset is current or personally appropriate.

How the calculation works

The calculator sums current balances, adds the entered origination fee to the new consolidated principal, calculates a new amortizing payment at the consolidation APR and term, and compares that APR with the balance-weighted current APR. This is the calculation method to use when checking the result from Debt Consolidation Calculator; values not represented by a visible input should not be inferred as part of the model.

Example

If current balances total $22,000 and the new consolidation rate is 10% over five years with no origination fee, the tool computes the new monthly payment on $22,000 and compares 10% with the weighted current APR.

How to interpret the result

The output tells you how much debt is entered, how much of the monthly budget is already committed to minimums, and how much remains to accelerate payoff. A weighted APR is a summary rate, not a full amortization schedule. The result is most informative when you also look at the component values that drove it.

Limitations and notes

A lower consolidation APR does not guarantee savings if the term is extended or fees are high. This implementation does not compare full month-by-month interest on the old debts with the new loan, so use lender disclosures for a true total-cost comparison. Recalculate when rates, balances, prices, dates, or policy rules change.
