Enter Your Debts & New Loan Terms
List your current debts and the new consolidation loan's rate and term, then click Calculate Consolidation to compare.
A debt consolidation calculator answers one specific question: if you rolled all your current debts into a single new loan, would you actually come out ahead — and by how much? NeftCal's debt consolidation calculator lets you list an unlimited number of existing debts, each with its own balance, interest rate, and minimum payment, then compares them as a group against a single proposed consolidation loan. It works as a debt consolidation savings calculator, a combine-debts calculator, and a monthly-payment-vs-total-interest comparison tool in one, built for anyone juggling multiple credit cards, personal loans, or store cards who's considering a personal loan, balance transfer, or HELOC to simplify repayment.
Most "debt consolidation calculators" online only show a single monthly payment number, which hides the real trade-off. A longer loan term can make your monthly payment drop dramatically while quietly increasing the total interest you'll pay over the life of the loan. This calculator deliberately shows both your current debts' total monthly payment, payoff time, and total interest, and the new consolidated loan's equivalents, side by side — plus a plain-language verdict that names the trade-off instead of just declaring a winner.
Anyone carrying two or more debts — credit cards, personal loans, store cards, or medical bills — who has been offered, or is considering applying for, a consolidation loan, balance transfer card, or home equity line of credit. It's equally useful for comparing multiple consolidation offers against each other, or simply understanding how much your current mix of debts is really costing you every month and over time.
High-interest revolving debt compounds quickly, and juggling several minimum payments with different due dates and rates makes it hard to see the full picture. Consolidation can lower your effective interest rate and simplify repayment to one due date, but it isn't automatically a good deal — the fee, rate, and especially the term you're offered determine whether you save money or just spread the same debt (or more) over a longer period. Running your actual numbers before signing is the only way to know which outcome you're getting.
Current debts are simulated month by month; the consolidated loan uses the standard amortization formula
From listing your debts to a clear verdict in under a minute
Enter each debt's name (optional), balance, interest rate, and minimum monthly payment. Use "+ Add Another Debt" for as many credit cards, loans, or store cards as you have.
Input the interest rate and term (in years) actually quoted for the new consolidation loan, plus an origination fee percentage if your lender charges one.
The calculator simulates your current debts month by month and computes the new loan's payment using standard amortization.
Review Total Balance, Weighted Average Rate, Total Monthly Payment, Payoff Time, and Total Interest for your Current Debts against the Loan Amount, Rate, Term, Monthly Payment, and Total Interest for the Consolidated Loan.
Check the verdict banner for a plain-language read on monthly cash-flow savings versus total-interest cost, then review the debt composition and payment comparison charts before deciding.
This calculator's own default three-debt scenario, consolidated at 11%/yr over 5 years with no origination fee
Three debts: a Credit Card with an $8,000 balance at 22%/yr and a $250/month minimum payment; a Personal Loan with a $12,000 balance at 14%/yr and a $350/month minimum payment; and a Store Card with a $3,000 balance at 26%/yr and a $100/month minimum payment. A new consolidation loan is offered at 11%/yr over 5 years (60 months) with no origination fee.
Explanation: This example is a clean win for consolidation because the rate drop is large enough to overcome the longer term. But it wouldn't take much to flip the total-interest result — stretching the same $23,000 loan to 7 years at the same 11% rate drops the monthly payment further to about $393.82, but pushes total interest up to roughly $10,081, which is actually more than the $9,470 the current debts would cost. That's the exact trade-off this calculator is built to surface: always check both numbers, not just the monthly payment.
How the new rate compares to your current weighted average rate is the single biggest driver of whether consolidation helps
The gap between your weighted average current rate and the new consolidation rate is the single strongest signal of whether consolidating will save you money — but the new loan's term decides whether that saving shows up as lower total interest, a lower monthly payment, or both. The bands below are general guidance, not a guarantee for your specific offer.
| New Rate vs. Weighted Avg Current Rate | General Read | Typical Context |
|---|---|---|
| 5+ percentage points lower | Strong candidate | Likely to save on both monthly payment and total interest unless the term is stretched much longer |
| 1–5 percentage points lower | Worth comparing carefully | Check total interest at your actual quoted term — a longer term can erase a modest rate saving |
| Roughly equal or higher | Consolidation likely not worth it | You're probably paying for convenience or a lower payment, not saving money — unless it stops high-rate balances from growing further |
Reading the verdict banner: a positive number in both the monthly payment and total interest comparisons means consolidation is a clear win on this calculator's assumptions. If only one is positive, you're trading one kind of benefit for the other cost — a real decision to make deliberately, not an automatic "yes."
The role of loan term: the new loan's term is often the biggest lever a lender can pull to make an offer look attractive. A 7 or 10-year consolidation term can make almost any rate look like a "lower monthly payment," even when total interest ends up higher than doing nothing at all.
Applying for a consolidation loan triggers a hard inquiry that can temporarily shave a few points off your score. In the months after, consolidating usually helps: paying off high card balances lowers your credit utilization, and one on-time loan payment builds a positive history — as long as you don't run the old cards back up.
The exact figure is your Current Total Interest minus the Consolidated Loan's Total Interest shown in the results above — in the page's default three-debt example, it's about $2,465. That saving only stays positive when the new rate is meaningfully below your weighted average current rate and the term isn't stretched so long that it outweighs the rate gain.
Consolidation makes sense when the new rate is enough below your weighted average current rate to cut your total interest, or when a single fixed payment and one due date solve a budgeting problem that juggling several minimums can't. Run your actual numbers above — if both the monthly payment and total interest improve, it's a strong candidate.
It's a good idea when it clearly improves your situation — typically a lower rate and a total-interest figure no higher than what your current debts would cost. It's usually not worth it if the only benefit is a lower monthly payment funded by a much longer term, since that means paying more interest overall.
A longer consolidation term can lower your monthly payment while increasing total interest paid — always check both figures before deciding. Consolidation also does not fix the underlying spending or budgeting habits that led to the debt; without a plan to avoid re-accumulating balances, some borrowers end up with both the new loan and new card debt.

What this debt consolidation calculator does well, and where it can't replace a lender's official offer
Typical ranges — actual offers depend heavily on your credit profile and lender
| Method | Typical Rate Range | Typical Term | Risk Notes |
|---|---|---|---|
| Personal (consolidation) loan | ~7% – 25%/yr, fixed | 2 – 7 years | Unsecured — no collateral at risk, but rate depends heavily on credit score |
| Balance transfer credit card | 0% promo, then ~18% – 27%/yr | 12 – 21 month promo window | Transfer fee (~3–5%) usually applies; unpaid balance at promo end reverts to a high standard rate |
| HELOC (home equity line of credit) | ~8% – 11%/yr, often variable | 10 – 20 years (draw + repay) | Home used as collateral — missed payments risk foreclosure; rate can rise with market rates |
| Debt management plan (via nonprofit credit counselor) | Often reduced to ~6% – 10%/yr by agreement | 3 – 5 years | Not a loan — a structured repayment plan; may involve closing existing credit accounts |
Consolidation merges your debts into one new loan that you repay in full at a hopefully lower rate — your balances are paid off and replaced by a single installment loan. Settlement, by contrast, negotiates with creditors to accept less than the full amount owed, which damages your credit and can trigger taxable forgiven debt, so it's usually a last resort.
Typical fees include an origination fee of roughly 1%–8% of the loan amount, a balance-transfer fee around 3%–5% if you use a transfer card, and sometimes late fees or prepayment penalties. Ask the lender exactly which fees apply to your quote and fold them into the calculator comparison before deciding.
Usually not immediately. Closing cards lowers your total available credit, which can raise your credit utilization and temporarily hurt your score, and it removes older accounts from your credit history — a key reason experts advise keeping cards open even if you stop using them.
Not quite. Refinancing replaces the terms of a single existing loan, usually to lock in a lower rate on the same debt, while consolidation combines several separate debts into one new loan. A consolidation loan can be refinanced later, but the two describe different moves.
