Debt Consolidation Calculator

How to use this calculator

Enter the details for each debt you're considering consolidating — balance, interest rate, and minimum payment — then enter the proposed consolidation loan's rate and term. The calculator compares the total interest and time to payoff under both scenarios: keeping each debt separate versus rolling them into a single loan.

Be realistic about the consolidation loan rate. The rate you qualify for depends on your credit score and income — it's not the advertised starting rate. If your credit score is under 680, the consolidation loan rate may not be meaningfully better than your existing debt rates, in which case a different payoff strategy may work better.

What your result means

The comparison shows two numbers that matter: total interest paid and months to payoff. A good consolidation reduces both. A break-even consolidation reduces one but not the other — for example, lower monthly payments but more total interest because the term is longer. That's a cash flow fix, not a debt fix, and it's worth knowing which one you're actually solving for.

The best-case scenario for consolidation is when you have multiple high-rate credit cards (18–29% APR) and can qualify for a personal loan at 8–14%. The math can save thousands in interest and simplify your payments down to one. The worst-case is using a long-term consolidation loan to lower monthly payments while extending the payoff timeline and paying more interest overall.

What the math leaves out

Consolidation calculator math assumes you stop using the credit cards you paid off. In practice, many people consolidate credit card debt and then gradually run the balances back up — ending up with the consolidation loan plus new card balances. If the spending pattern that created the debt hasn't changed, consolidation may delay rather than solve the problem.

This calculator also doesn't account for origination fees on personal loans (typically 1–8% of the loan amount, deducted upfront), which reduce the effective savings. Factor those in before concluding a loan is worth it.

When consolidation makes sense — and when it doesn't

Consolidation tends to make sense when: you have multiple high-rate debts, you qualify for a meaningfully lower rate, you can commit to not re-accumulating the debt, and the term keeps total interest paid lower than the current path. It tends not to make sense when: the rate reduction is minimal, the consolidation extends your payoff significantly, you don't address the underlying spending, or you're consolidating secured debt (home equity) to pay off unsecured debt, which increases risk.

How to compare consolidation honestly

The cleanest comparison is not “old payment versus new payment.” It is old total cost versus new total cost. A consolidation loan can lower the monthly payment by stretching the term, but that can also keep you in debt longer. Before deciding, compare the current payoff path, the proposed consolidation payment, the total interest, any origination fee, and the month when the debt would actually be gone.

A good rule of thumb: consolidation should make the debt simpler and cheaper. If it only makes the payment smaller, look closely at the tradeoff. There are times when a lower payment is necessary for cash flow, but that is different from saving money. Naming the goal clearly helps keep the math honest.

A quick example

Say you have three credit cards totaling $12,000 at an average 24% APR. If the current payments barely cover interest, the payoff timeline can stretch for years. A 36-month personal loan at a lower APR may create a fixed endpoint and reduce the interest cost. But if the loan term is 60 or 72 months, the smaller payment may come with a longer runway and less savings than expected.

That is why this calculator asks for both sides of the decision. It is not trying to make consolidation look good or bad. It is trying to show whether the move actually changes the outcome.

Common mistakes to avoid

• Comparing only monthly payments. A lower payment can feel like relief, but total interest tells you whether the move is actually cheaper.
• Ignoring fees. Origination fees, balance transfer fees, and annual fees can reduce or erase the savings.
• Keeping the cards active for regular spending. If the balances return after consolidation, the loan becomes another payment instead of a solution.
• Using home equity for unsecured debt too quickly. Moving credit card debt onto your home can lower the rate, but it also adds collateral risk.
