Debt Consolidation Calculator: Compare Loan Savings

Debt consolidation can simplify several payments, but the new loan only improves the math when payment, repayment time and total financing cost work together. Compare the current debts with a real loan offer before treating a lower monthly payment as savings.


Debt Consolidation Calculator

Current debts
Add the unsecured debts you would replace with one consolidation loan. The new loan amount is based on the total balances listed here.

Consolidation loan
Use the loan's interest rate. If the lender only shows APR, check whether that APR already includes origination fees.
The fixed repayment term for the consolidation loan.
Replace the illustrative value with the actual fee, or leave blank for 0%.
If deducted, the calculator increases the gross loan so net proceeds still cover all listed balances.

Current debts are modeled separately using each entered balance, APR and fixed monthly payment; payments are not rolled to another debt after an account is paid off. The consolidation scenario uses standard fixed-rate amortization. When an origination fee is deducted from proceeds, the gross loan is increased so the net amount available still equals the balances being consolidated.

Educational estimate only. Actual loan costs depend on the lender's interest calculation, APR disclosures, fee treatment, approved amount and terms. A lower monthly payment can still cost more overall when repayment is extended. Confirm the offer documents before consolidating debt.

How to Use the Debt Consolidation Calculator

Add only the debts the new loan would actually pay off. For each account, enter the current balance, APR and monthly payment.

Then enter the proposed consolidation loan’s interest rate, repayment term and origination fee. Leave the fee blank when the offer has no origination fee.

The fee-treatment selector distinguishes a fee deducted from loan proceeds from one paid separately upfront. Prefilled debts and loan terms are illustrative examples rather than current market averages or loan offers.

What the Main Results Tell You

Consolidation loan payment is the fixed monthly payment on the modeled new loan. It is compared with the combined amount currently being paid across the listed debts.

Estimated financing-cost change compares remaining modeled interest on the current debts with interest and origination-fee cost on the new loan. Positive savings require more than a lower headline rate.

Review metrics keep two other tradeoffs visible: how the monthly payment changes and whether the consolidation term is shorter or longer than the current modeled payoff path. Origination-fee impact shows how much the fee changes cash or principal.

How the Current Debt Path Is Modeled

Each listed debt is projected separately using its current balance, APR and entered monthly payment.

Modeled monthly interest
Remaining balance x APR / 12

Interest is added monthly and the entered payment is applied until the balance reaches $0. Current payoff time is the longest payoff period among the included accounts because the household is not debt-free until the final account is finished.

Payments are not rolled from a paid-off debt to another balance in this baseline. Current-debt modeling therefore answers a specific comparison question: what happens if each payment stays attached to its current account?

A strategy that keeps the entire monthly debt budget level after each payoff is different. The debt payoff calculator models snowball and avalanche separately.

How the Consolidation Loan and Origination Fee Work

Consolidation math uses standard fixed-rate amortization. At 0% interest, principal is divided evenly across the entered number of monthly payments.

Fixed monthly payment
Loan principal x monthly rate / [1 – (1 + monthly rate)^(-number of payments)]

When an origination fee is deducted from proceeds, less cash reaches the borrower than the gross loan amount. To keep net proceeds equal to the balances being consolidated, the calculator grosses up modeled principal.

Gross loan with deducted fee
Debt payoff amount / (1 – origination fee rate)

For example, borrowing exactly $20,000 with a 5% fee deducted from proceeds would leave only $19,000 available for creditors. Grossing up the loan preserves the $20,000 net payoff amount but increases both the financed fee and the principal on which interest can accrue.

Upfront fees work differently. Loan principal remains equal to the debt payoff amount, while the fee is added separately to modeled financing cost.

Interest Rate, APR and Total Cost Are Different Measures

New-loan input asks for the interest rate because the origination fee is modeled separately. APR can include certain finance charges, so entering an APR that already reflects the fee and then adding the same fee again can double-count cost.

Use the note rate from the loan offer when available. An APR-only offer requires closer review of the disclosures before deciding what belongs in the separate fee field.

Lower interest alone does not guarantee lower lifetime cost when the loan lasts much longer. A lower consolidation payment can come from extending repayment, which may increase total cost once fees and loan length are included.

When Consolidation Improves the Math

Consolidation becomes more compelling when financing cost after fees falls, the new payment fits the budget and the payoff term does not stretch substantially just to create monthly relief.

Combined current payments can decline naturally as individual debts finish. A consolidation loan instead keeps one fixed payment until the final scheduled payment, so today’s payment difference should not be confused with lifetime savings.

Paid-off revolving accounts also create a behavioral risk if balances are run back up. Consolidation changes the repayment structure; it does not reduce principal by itself or fix ongoing spending above income.

When Another Debt Option May Be Better

Weak consolidation math does not automatically mean another loan is required. Existing balances can still be addressed through structured payoff, creditor hardship options or nonprofit credit counseling.

Debt settlement is different from a consolidation loan. Settlement programs can involve stopping payments while funds accumulate, which may lead to additional interest, penalties, collection activity and credit damage.

Secured consolidation also changes risk. Moving unsecured credit-card debt into debt secured by a home can expose the property to foreclosure if the new loan is not repaid.

Frequently Asked Questions (FAQs)

How do I know if debt consolidation saves money?

Compare the current modeled interest with the new loan’s interest and origination-fee cost, then check the payoff term. Lower monthly payment alone does not establish savings.

Why does the calculator use interest rate instead of APR?

The origination fee is modeled separately. Using an APR that already includes that fee and adding the fee again could double-count part of the borrowing cost.

Why can the gross loan be larger than my debt balance?

Fees deducted from proceeds leave less money available for creditors. Grossing up the loan lets modeled net proceeds still equal the balances being consolidated.

Should I include secured debt?

Use caution. Mortgages, auto loans and some student loans have collateral or repayment features that differ from ordinary unsecured consumer debt and may deserve product-specific analysis.

What if the result is close to break-even?

Convenience may then be the main benefit. Compare fee treatment, repayment length, lender protections and the value of replacing several payments with one fixed payment.

Can consolidation affect my credit?

Applying for new credit can create a hard inquiry, and opening or closing accounts can change credit-profile metrics. Future effects depend on payment history, balances and the rest of the credit file.
