Should you consolidate
your debts into one loan?

Field guide

What debt consolidation actually does and what it doesn't.

Debt consolidation means taking multiple separate debts and combining them into a single new loan, typically at a lower interest rate and with a single monthly payment. It doesn't eliminate your debt — it restructures it. Whether consolidation is actually beneficial depends on three factors: the new interest rate, the new term length, and what you do with the freed-up cash flow.

The central tension in consolidation is monthly payment vs. total cost. A longer loan term almost always reduces the monthly payment but increases the total interest paid. A shorter term at a lower rate is the ideal, but the rate improvement needs to be enough to actually reduce total cost, not just spread it out thinner.

Secured vs. unsecured consolidation, a critical distinction.

Consolidation loans come in two forms with very different risk profiles:

• Unsecured personal loan. No collateral required. Lenders qualify you based on credit score and income. Rates typically range from 7% to 36% depending on creditworthiness. If you default, lenders can sue and garnish wages, but they cannot seize your home or car automatically. This is the most common form of consolidation for credit card debt.
• Home equity loan or HELOC (secured). You borrow against your home's equity at a much lower rate, often 7–10% even in higher-rate environments. The catch: your home is collateral. If you default, you can lose it. Converting unsecured credit card debt into a secured home-equity loan trades a lower rate for vastly higher downside risk. Financial advisers generally caution against this unless you have strong repayment confidence.
• Balance transfer credit card. Many credit cards offer 0% APR for 12–21 months on transferred balances, with a 3–5% transfer fee. This can be an excellent tool for high-rate credit card debt if you can pay off the balance within the promotional window. After the window closes, the rate typically jumps to 20–29%.
• 401(k) loan. Some employer plans allow borrowing against your retirement balance. No credit check, typically low rates. The risk: if you leave your job, the outstanding balance may become due immediately and unpaid amounts are treated as distributions, triggering income tax plus a 10% early withdrawal penalty. Raiding retirement savings for consumer debt is generally a last resort.

The hidden risks of debt consolidation.

Extending the term costs more even at a lower rate

The most common mistake: getting excited about the lower monthly payment without calculating total interest. Extending a 2-year high-rate payoff into a 5-year lower-rate loan often increases total interest paid substantially. The calculator's Verdict card flags this explicitly. If consolidation lowers your payment but raises your total cost, it's not actually saving you money.

Closing old accounts hurts your credit utilisation

Credit score models factor in credit utilisation, the ratio of your outstanding balances to your total available credit. If you consolidate and close the original credit card accounts, your total available credit drops, which raises your utilisation ratio and can lower your score in the short term. Keeping the paid-off accounts open (with a zero balance) maintains your available credit.

The “new card” spending trap

A common pattern: consolidate credit card balances into a personal loan, then run the cards back up again. You now have the consolidation loan plus new card debt — far worse than before. Consolidation only works if you address the underlying spending that created the debt. Without that change, it's a temporary fix that delays a larger problem.

Origination fees reduce the benefit

Personal loans often charge origination fees of 1–8% of the loan amount, deducted upfront from the disbursement (or added to the principal). A $20,000 loan with a 5% origination fee means you receive $19,000 but owe $20,000. This fee should be factored into your effective rate when comparing options.

When does consolidation make clear sense?

The strongest cases for consolidation:

• High-rate credit card debt + qualifying credit score. If you have 22–29% APR credit card debt and can qualify for a personal loan at 10–14%, the interest savings over even a 3-year term are substantial and unambiguous.
• Multiple payments causing payment fatigue. Managing 5–6 different due dates, minimum payments, and accounts is cognitively and logistically burdensome. Simplification has real value even if the financial math is roughly neutral.
• A fixed payoff date creates accountability. An installment loan with a defined end date forces payoff in a way that revolving credit card debt does not. If discipline is the issue, the structure of a loan can be the solution.
