Debt Consolidation Calculator – Does It Actually Save Money?

Debt Consolidation Calculator — Does It Actually Save You Money?

The advert made it sound simple. One loan. One payment. Lower rate. Freedom. What the advert did not tell me was that I would pay off the cards, feel the relief, and spend on them again within eight months. Two years later I had the consolidation loan and nearly the same credit card balances I started with. That is the most common consolidation failure and this calculator is the only free tool that specifically warns you about it.

Debt consolidation works for some people and makes things significantly worse for others. This tool gives you the exact maths — not just whether the rate is lower, but whether the total cost over the full term actually saves you money after fees.

When Consolidation Works

Consolidation saves money when three things are true. Your new rate is genuinely lower than your weighted average current rate. The term is not so long that extra interest cancels the rate saving. And you do not spend on the cards you clear. All three must be true. The calculator checks the first two mathematically. The third one is on you.

When Consolidation Makes Things Worse

Alternative to a Loan — 0% Balance Transfer

If your total credit card debt is under £20,000 and you have a decent credit score, a 0% balance transfer card is often cheaper than a consolidation loan. Transfer fee is typically 2–3%. Zero interest for 12–24 months. You pay only principal. The calculator shows you the balance transfer comparison automatically.

Frequently Asked Questions — Debt Consolidation Calculator

What APR do I need to make consolidation worthwhile?

Your consolidation loan APR must be lower than the weighted average APR across your current debts. If your cards average 24% APR and you qualify for a 12% consolidation loan, the maths works. If you only qualify for 22%, the saving is minimal and may not justify the fees and effort.

Does consolidating debt hurt my credit score?

Short term — yes. A hard credit search for the loan application drops your score a few points. If you close the credit cards you paid off, your available credit decreases and utilisation may spike temporarily. Medium term — if you make consistent payments and keep the cleared cards at zero, your score typically improves within 6–12 months.

Can I consolidate debt with a bad credit score?

You may qualify for a secured loan (using your home as collateral) or a guarantor loan. Both carry significant risks — defaulting on a secured loan puts your property at risk. If your credit score is too low for a good rate, a Debt Management Plan through StepChange may be more appropriate — they can often negotiate lower interest rates with your creditors for free.

Should I consolidate or use the debt avalanche method?

Run both through our tools. Use this calculator to get the consolidation total cost. Then use our AI Debt Payoff Planner to run the avalanche strategy on your current debts. Compare the total interest paid. Whichever is lower — and which you can actually stick to — is the right answer.

What happens to my credit cards after consolidation?

Do not close them immediately — this hurts your credit score. Keep them open at zero. Cut them up if you cannot trust yourself. Consider asking your issuer to reduce the limit to a small amount. The worst outcome is keeping them open and spending on them again.
