What This Debt Consolidation Calculator Does

Debt consolidation combines multiple debts — credit cards, medical bills, personal loans — into a single new loan with one monthly payment, ideally at a lower interest rate. This calculator shows how much you could save in interest and how much sooner you could be debt-free by consolidating, compared to continuing to pay each debt separately at current minimum or fixed payments.

How It Works

The calculator runs a month-by-month amortization of each existing debt under your current payment schedule, then runs the same simulation for a single consolidation loan covering the total balance. The difference in total interest paid is your potential gross savings. Net savings deduct origination fees, balance transfer fees, or other consolidation costs.

Key Concepts Explained

Balance Transfer Cards

A 0% APR balance transfer card is often the cheapest consolidation option if you qualify. The 0% period runs 12–21 months, with transfer fees typically 3–5% of the transferred balance. If you pay off the balance within the promotional period, your total cost is just the transfer fee. After the promo period, rates jump to 20–30%.

Debt Consolidation Loans

Unsecured personal loans from banks, credit unions, or online lenders are the most common consolidation tool. Rates range from 6% for excellent credit to 36% for poor credit. Credit unions often offer the lowest rates for members. If your consolidation rate is higher than your weighted average current rate, consolidation saves nothing on interest.

Weighted Average Interest Rate

Your weighted average rate is the blended rate across all debts, proportional to their balances. A consolidation loan only saves money if its rate is meaningfully below this weighted average — accounting for fees.

Tips & Best Practices

Frequently Asked Questions

Will debt consolidation hurt my credit score?

Initially, yes — a new loan creates a hard inquiry and lowers average account age. However, reducing credit utilization on revolving accounts can improve your score medium-term. Paying the consolidated loan on time consistently will rebuild credit over 12–24 months.

What's the difference between debt consolidation and debt settlement?

Consolidation pays debts in full through a new loan or DMP — credit is not severely damaged. Settlement negotiates with creditors to accept less than owed (typically 40–60 cents on the dollar), severely damages credit, and the forgiven amount is generally taxable as income (Form 1099-C).

Is it better to consolidate or use the avalanche/snowball method?

The avalanche (highest rate first) and snowball (smallest balance first) methods cost nothing and are often better than consolidation if the rate reduction from consolidating would be minimal. Consolidation makes more sense when the rate reduction is significant (5+ percentage points) or when you genuinely need the simplicity of one payment.

How much debt should I have to consider consolidation?

Consolidation is most compelling with $5,000+ in high-interest debt across multiple accounts, when primarily making minimum payments, and when you can qualify for a rate at least 3–5 percentage points below your weighted average. Amounts under $2,000 are often better handled directly with snowball or avalanche.
