The Debt Consolidation Calculator compares keeping several debts separate with replacing them by one consolidation loan. Enter each current balance, rate, and payment or term, then the consolidation rate, term, and any fees, and the Debt Consolidation Calculator returns the new single payment and a before-versus-after cost comparison.
Consolidation is a financing decision, not a magic erase. The Debt Consolidation Calculator asks whether the new loan's interest and fees beat the combined cost of the old debts over the life of each path.

Calculate debt consolidation savings
The Debt Consolidation Calculator calculates debt consolidation savings by totaling what the existing debts would cost if paid as scheduled, then totaling what the new loan would cost, and subtracting. Savings exist only when the after path is cheaper on an honest horizon, fees included.
Example before set: $4,000 card at 22% with a $120 fixed payoff plan; $6,000 card at 18% with a $150 plan; $2,000 personal loan at 14% with a $90 plan. Combined monthly outflow is $360. A consolidation loan of $12,000 at 12% for 48 months has a payment of about $316 (using PMT = PV x r(1+r)^n / ((1+r)^n - 1) with r = 0.01). The Debt Consolidation Calculator then compares total dollars paid on the old path versus 48 x $316 plus any origination fee on the new path.
If the old plans would have finished earlier at higher rates, stretch both stories to clear dates before calling a winner. A shorter old path with high rates can still beat a long cheap refinance on total interest.
Compare the cost before and after
The Debt Consolidation Calculator compares the cost before and after with the same definition of cost: all interest and fees until principal is repaid. Monthly payment drop alone is not proof of savings. Fair compares use the same principal and an honest payoff horizon.
Before: sum of remaining interest on each debt under its current payment schedule. After: interest on the consolidation loan over its term plus fees. Principal cancels in a fair compare when both paths repay the same $12,000. Suppose the separate plans would still charge about $2,800 of remaining interest combined. The 12% four-year loan charges 48 x about $316 minus $12,000, or roughly $3,168 of interest. In that sketch the payment fell from $360 to $316 but total interest rose, so consolidation looks worse on cost even though cash flow eased. The Debt Consolidation Calculator exists to catch that pattern. Change the consolidation rate to 9% and the interest total falls; the decision can flip.
Always add origination fees and balance-transfer fees into the after column. A 3% fee on $12,000 is $360 cash at closing that belongs in the after cost even when it is rolled into the loan.
Find the new single payment
The Debt Consolidation Calculator finds the new single payment from the consolidated principal, the new APR, and the new term using standard amortization. One payment replaces many, which is the cash-flow appeal. Longer terms lower the installment but can raise lifetime interest.
For $12,000 at 12% over 48 months, monthly rate r = 0.01, n = 48, PMT about $315.67. At 36 months the payment rises to about $398.86; at 60 months it falls to about $266.93. The Debt Consolidation Calculator shows that term length trades payment size against interest duration. A lower payment funded by a much longer term can erase rate advantages. Match the term to how long the old debts would have lasted when judging fairness.
Taxes, insurance, and unrelated bills stay outside this payment figure. Secured consolidations may add collateral risk that a payment comparison does not capture.
Decide whether to consolidate
The Debt Consolidation Calculator helps decide whether to consolidate by lining up four checks: lower total cost after fees, affordable single payment, equal or shorter effective payoff horizon, and discipline not to refill the old cards. A pass on payment size alone is not enough.
If after-fees cost is higher, consolidation is a cash-flow tool, not a savings tool; say so plainly. If cost is lower but the term runs years past the old payoff dates, part of the win is just stretching. If cards remain open and balances climb again, the borrower now holds the consolidation loan plus new revolving debt. The Debt Consolidation Calculator quantifies the loan maths; behavior after closing sits with the reader.
Cross-link the Debt Payoff Calculator when keeping the debts separate and attacking them with avalanche or snowball is the better path. Lender credit pulls and collateral on secured consolidations are outside the arithmetic but matter in the real application.
A second worked compare helps: roll $8,000 of card balances at 19% into a $8,000 personal loan at 11% for 36 months. The new payment is about $262. The Debt Consolidation Calculator still asks for remaining interest on the card payoff plan at the borrower's actual fixed payment, then subtracts the personal-loan interest plus fees. If the cards were already on track to clear in 20 months at a high payment, stretching to 36 months can erase the rate win. Run both horizons before signing.
Frequently asked questions
How does the Debt Consolidation Calculator compare options?
The Debt Consolidation Calculator compares options by totaling cost on the current debts versus cost on one new loan, including fees. It also shows the new single payment. A lower monthly payment does not always mean lower total cost.
What is a consolidated payment?
A consolidated payment is the single amortized installment on the new loan that replaces multiple old payments. The Debt Consolidation Calculator computes it from principal, rate, and term. For $12,000 at 12% over 48 months, the payment is about $316.
When does consolidation save money?
Consolidation saves money when the after path's interest plus fees is less than remaining interest on the old debts for a fair payoff window. The Debt Consolidation Calculator runs that subtract. Rate cuts help; long terms and high fees can cancel the help.
Should fees be included?
Fees should be included in the after cost. The Debt Consolidation Calculator should add origination or transfer fees to the new loan's burden. Ignoring fees overstates savings.
Is a lower payment always better?
A lower payment is not always better. The Debt Consolidation Calculator may show a lower payment with higher lifetime interest when the term stretches. Judge payment comfort and total cost together.
How does this relate to debt payoff strategies?
This relates to debt payoff strategies as an alternative path: one new loan versus many old ones under avalanche or snowball. The Debt Consolidation Calculator covers the refinance compare. The Debt Payoff Calculator covers strategy on debts kept as-is.
Summary
The Debt Consolidation Calculator weighs a multi-debt status quo against one replacement loan by comparing total cost and the new amortized payment. A $12,000 refinance at 12% for 48 months pays about $316 per month, but that cash-flow relief only counts as savings if interest plus fees beat the old remaining interest on a fair timeline.
Fees, longer terms, and refilled cards can erase the paper win. These results are estimates for information only, not financial advice.
