Debt Consolidation Calculator

What debt consolidation actually does

Debt consolidation combines multiple debts (credit cards, personal loans, store cards) into a single new loan, ideally at a lower interest rate. You get one monthly payment instead of many, lower total interest, and a fixed payoff date instead of revolving balances. The math is straightforward: if you can replace 22% credit card debt with 10% personal loan debt over the same payoff period, you save thousands.

The key word is “ideally.” Consolidation works mathematically only if the new loan’s effective cost (including fees) is lower than the current weighted average cost. Many consolidation offers fail this test once you factor in origination fees, longer terms that increase total interest, or rates that are not actually lower for borrowers with mediocre credit.

Consolidation does not eliminate debt — it restructures it. You still owe the same principal. The only thing that changes is the cost of carrying that debt and the payment structure. People sometimes treat consolidation as a fresh start and immediately run credit cards back up, ending up with the consolidation loan PLUS new credit card debt. This is the single most common consolidation failure mode.

Five consolidation options ranked

1. Personal loan (best for most borrowers)

A fixed-rate, fixed-term unsecured loan. You receive the lump sum, use it to pay off all credit cards, then make one monthly payment for typically 2-7 years. Rates: 7-15% for good credit (700+), 15-25% for fair credit (650-700), 25-36% for poor credit (below 650). No collateral required, so your home and assets are not at risk if you cannot pay.

Best for: anyone with good-to-excellent credit consolidating $5K-50K of credit card debt. Worst for: people with poor credit (rates often not better than existing cards).

2. 0% balance transfer credit card

Move all balances onto a single new card offering 0% APR for 12-21 months. Pay no interest during the promo period. Fees typically 3-5% of transferred balance. Best when: you can fully pay off the balance during the promo period. Worst when: you can not, and rate jumps to 25-30% after promo expires (often higher than original card).

Best for: borrowers with excellent credit (720+) and $5K-15K balance who can clear it in 12-21 months. Mathematically optimal when timing aligns.

3. Home equity loan or HELOC

Borrow against home equity at much lower rates (typically 6-10%) than unsecured options. Tax-deductible interest in the US for substantial home improvements (not for general consumer debt). The catch: your home is the collateral. Missing payments risks foreclosure. The 2008 crisis was full of borrowers who consolidated credit card debt into home equity and then lost their homes.

Best for: homeowners with significant equity (50%+) and stable income, willing to risk the home for lower rate. Worst for: anyone whose income is shaky or who might be tempted to run cards back up.

4. 401(k) loan (US)

Borrow against your own retirement account. Rates typically prime + 1% (so 7-9% currently). No credit check, no underwriting — you are effectively borrowing from yourself. The downside: you lose investment growth on the borrowed amount, and if you leave your job, the loan typically becomes due within 60-90 days (or it counts as a distribution with taxes and penalties).

Best for: secure long-term employees with stable jobs consolidating $5K-25K. Worst for: anyone whose employment might change in the next 5 years.

5. Debt management plan (DMP, non-profit credit counseling)

Not technically a loan — a non-profit credit counseling agency negotiates lower rates and a single monthly payment with your creditors. Typical agreed rates: 6-12% (much lower than card APRs). Fees: $25-50/month. Affects credit score during the program but recovers after completion. Plans typically last 3-5 years.

Best for: borrowers who do not qualify for low-rate personal loans due to credit issues, but have stable income. Worst for: borrowers with high-credit who would do better with a personal loan.

When consolidation actually helps

The math works when:

• New APR is meaningfully lower than current weighted average. Going from 22% to 10% saves real money. Going from 22% to 20% barely moves the needle and often gets eaten by fees.
• You will not add new debt to old cards. Consolidation only works if you stop using the cards you cleared. Add new charges and you are worse off than before.
• You can afford the new monthly payment. Personal loans require minimum monthly payments often higher than credit card minimums. If the new payment strains your budget, you may default and damage credit further.
• Total fees (origination + closing) are less than projected savings. A 5% origination fee on $20K is $1,000 — make sure interest savings exceed that.
• The loan term is not longer than necessary. Stretching a 3-year payoff into 5 years can increase total interest even at a lower rate. Pick the shortest term you can afford.

The math fails when:

• You consolidate into a loan with a long term to lower monthly payment, paying more interest over time. Example: $20K at 22% over 3 years = $7,395 interest. Same $20K at 10% over 7 years = $7,892 interest. Lower rate, higher total interest because of the longer term.
• You qualify only for high-APR personal loans because of poor credit. A 24% personal loan vs 22% credit card is not consolidation, it is reshuffling.
• You add a 5-8% origination fee that wipes out the interest savings. Many sub-prime consolidation lenders profit primarily from fees, not interest.
• You consolidate, then run up the cards again. By far the most common failure. Now you have the consolidation loan AND new credit card balances.

Hidden costs that ruin the math

Consolidation loan advertisements emphasize the APR and ignore the surrounding costs. A loan offered at “10% APR” might effectively cost 14% once fees are added. Watch for:

• Origination fees: 1-8% of the loan amount, deducted upfront. On a $20K loan with 5% origination, you receive $19K but owe $20K. Effective rate is meaningfully higher than the stated APR.
• Application or processing fees: Some lenders charge $50-200 upfront.
• Prepayment penalties: Pay the loan off early and some lenders charge you. Common in less-regulated markets. Read the contract.
• Late payment fees: $25-50 per late payment, similar to credit cards. Set up autopay.
• Required loan insurance: Some lenders push payment protection insurance at 0.5-2% per month. Usually overpriced; decline unless you have specific needs.
• Balance transfer fees: For 0% transfer cards specifically, 3-5% of transferred balance is the norm.
• HELOC closing costs: 2-5% of loan amount, often $1,500-3,000 minimum. Eats significant savings on smaller balances.

The honest comparison method: calculate the total cost of the new loan including all fees, then compare to total cost of current debts at current payments. If the difference is more than ~10% of the loan amount, consolidation makes sense. Less than that, the time-and-effort and credit-score impact may not be worth it.

Debt Consolidation Calculator FAQ

What credit score do I need for a good consolidation loan?

For the best personal loan rates (7-10% APR), you typically need 720+ credit score. 680-720 gets you 10-15%. 640-680 gets you 15-25%. Below 640, rates are typically 25%+ and often not better than the credit cards you would replace. If your credit is below 640, focus first on credit repair (pay everything on time for 6-12 months, dispute errors on credit reports) before pursuing consolidation.

How does consolidation affect my credit score?

Short term: small dip (5-15 points) from the hard inquiry and new account. Medium term: improves as you reduce credit utilization (your old cards now have $0 balance with the same limits). Long term: significantly improves as the consolidation loan reports on-time payments and your debt-to-income ratio drops.

Should I close my credit cards after consolidating?

Usually no. Closing accounts reduces total available credit, which increases utilization ratio (a key credit score factor). Keep cards open with $0 balance — your score will be higher than if you closed them. Exception: high annual fee cards you genuinely will not use again.

What is “weighted average APR” and how do I calculate it?

Sum each balance × its APR, then divide by total balance. Example: $5K at 18% + $3K at 24% + $2K at 26%. Weighted = ($5K × 0.18 + $3K × 0.24 + $2K × 0.26) ÷ $10K = ($900 + $720 + $520) ÷ $10K = $2140 ÷ $10K = 21.4% weighted APR. Use this as your “current APR” input.

Can I consolidate federal student loans this way?

Generally no, and you usually should not. Federal student loans have unique benefits (income-driven repayment, public service forgiveness, deferment options) that are lost when consolidated into private loans. Federal direct consolidation is a separate program through the government — different process, preserves benefits. For private student loans, refinancing into a personal loan can sometimes save money but evaluate carefully.

What about debt settlement? Is that the same as consolidation?

No. Debt settlement is when you stop paying creditors and try to negotiate a lump-sum payoff for less than you owe. It severely damages credit (you defaulted) and the forgiven amount may be taxable as income. Settlement firms often charge 15-25% of settled debt as fees. Avoid unless bankruptcy is the only alternative — at which point, talk to a bankruptcy attorney before paying any settlement firm.
