Debt Consolidation Calculator

Use this debt consolidation calculator to compare a loan vs your current debts and see whether the offer improves total cost, payoff time, monthly payment, and fees.

Your numbers

Example loaded: two credit cards and one personal loan compared with a 48-month consolidation loan at a 12.99% interest rate and a 3% origination fee.

Enter your current balances, APRs, minimum payments, and the loan offer you want to compare.

Loaded your last numbers

1) Current debts

Enter additional balances, APRs, and minimums.
On top of all minimum payments (current debts) and on top of the consolidation loan payment (if you choose).

2) Consolidation loan

Enter the loan's interest rate, not its disclosed APR. APR can include origination charges and other loan costs, so entering APR here and the same fee below could count part of the cost twice. Learn the difference between interest rate and APR.
After calculation, this will compare the disclosed loan APR when provided; otherwise it will compare the loan interest rate.
Enter the APR shown in the lender's offer or disclosure. It is displayed for comparison only and does not drive the payment calculation.
Example: 60 months = 5 years.
Commonly 0%–8% (varies widely).
Optional: closing/admin fees, etc.
If checked, fees are added to the loan amount (you borrow them).
If you override the payment, payoff time may differ from the term.
Some people prefer keeping the loan payment fixed and using “extra” elsewhere.
Uses standard amortization math. Estimates only.
Some fields were prefilled from the previous page. Enter the consolidation loan offer, adjust the extra payment if needed, then click Calculate.

How this calculator works

This calculator compares your current debts with a consolidation loan scenario using the loan amount, interest rate, optional disclosed APR, term, fees, and payment assumptions you enter.

The current debt estimate uses the existing balances, APRs, and payments. The consolidation estimate uses the loan interest rate for amortization, models the entered fees separately, and treats the optional disclosed APR as an informational comparison measure. It then compares monthly payment, payoff time, total interest, fees, and total cost.

Rate and fee basis

Payment and interest estimates use the loan interest rate. The optional disclosed APR is informational only, and separately entered fees are modeled on their own.

  • Current debts: Monthly interest is estimated using each debt's APR ÷ 12. You pay each fixed minimum, and any extra payment targets the highest APR first (Avalanche method).
  • Current minimum payments are treated as fixed dollar amounts, not issuer-specific percent-of-balance formulas.
  • Consolidation loan: Monthly amortization uses the loan interest rate ÷ 12 and a fixed payment unless you override it.
  • The optional disclosed loan APR is shown for comparison only. It does not drive the loan payment or interest calculation.
  • APR can include the interest rate and certain lender charges. Do not enter the disclosed APR as the interest-rate input when the same origination fee is also entered separately.
  • If you override the loan payment, payoff time may be shorter or longer than the selected term.
  • Fees are either rolled into the loan balance or treated as paid upfront and added to total cost.
  • If fees are rolled into the balance, they become part of principal and accrue interest.
  • Extra monthly payment is applied to the loan only when “Apply extra to loan?” is set to Yes.
  • No promotional-rate changes, penalty-rate changes, late fees, prepayment penalties, or lender-specific minimum formulas are modeled.

How to interpret the comparison

Compare the monthly payment, total cost after interest and fees, and payoff time together. A lower payment can help cash flow, but it can also come from stretching the balance over a longer loan term.

When consolidation looks stronger

The loan has the clearest advantage when its lower interest rate still produces a lower total cost after fees and keeps the payoff timeline reasonable.

When the lower payment has a tradeoff

If the payment falls while payoff takes longer or total cost rises, the loan is improving affordability without improving the full repayment result.

When the current plan is competitive

If the current debts are cheaper, faster, or close to the loan result, switching may offer more convenience than financial savings.

Check the actual offer:

Use the loan interest rate for the payment estimate, compare the lender's disclosed APR, and confirm the term, fees, amount financed, and prepayment rules before deciding.


What to test when the result is mixed

When consolidation helps in one area and hurts in another, change one assumption at a time to see what would materially improve the comparison.

Test the loan terms

Try a lower interest rate, shorter term, or smaller fee to see what the offer would need to beat your current payoff plan.

Test extra payments

A modest extra payment may make the current plan competitive or shorten the consolidation loan enough to reduce its total cost.

Test a payoff target

If affordability is the main concern, work backward from a payoff date to compare the monthly payment each option would require.


About this calculator

This calculator is built by DebtOptimizerHub to help users compare whether a consolidation offer improves repayment cost, monthly payment, or payoff timing.

Results are educational estimates. They do not reproduce a lender's formal APR disclosure and do not replace lender disclosures, loan agreements, origination-fee terms, credit approval, variable-rate changes, prepayment rules, or financial advice.


Debt consolidation calculator FAQ

How do I know if debt consolidation saves money?

Debt consolidation saves money when the new loan’s interest and fees are lower than the cost of keeping your current debts. A lower payment alone does not always mean the loan saves money, because a longer term can increase total cost.

Does debt consolidation lower monthly payments?

Debt consolidation can lower monthly payments if the new loan has a lower rate, longer term, or both. The tradeoff is that a longer term may keep the debt around longer even if the monthly payment is easier to manage.

Should I consolidate debt if the loan has fees?

Fees should be included in the comparison. A consolidation loan can still be worthwhile with fees, but only if the lower rate or better payment structure is strong enough to offset the added cost.

Should I enter the loan interest rate or the disclosed APR?

Enter the loan interest rate in the required rate field because that is the rate used to calculate amortization. Enter the lender's disclosed APR only in the optional APR field. APR can include the interest rate and certain loan charges, so using APR as the interest-rate input while also entering the same origination fee can count part of the cost twice.

Is a lower APR always better for debt consolidation?

A lower disclosed APR can be a useful initial comparison, but it does not settle the decision by itself. The loan term, monthly payment, amount financed, origination fee, other charges, and total repayment cost can still make the offer more or less expensive. This calculator uses the loan interest rate for payment modeling and treats separately entered fees as separate costs.

What is the difference between debt consolidation and paying debts separately?

Debt consolidation replaces multiple debts with one new loan. Paying debts separately keeps the original balances and rates in place, often using a strategy like avalanche repayment to target higher-rate debts first.
