When does switching actually make sense?

The short answer

A refinance makes sense when a new loan, after every fee is counted, costs less than keeping the one you have, or fits your life in a way the current one doesn't. That's the whole test. The signals below are just the situations where that test tends to come back positive, and the ones where it tends not to.

One framing helps before the list: your loan was priced on a single day, against the file you had and the options you saw at that moment. Everything on both sides has been moving since: your income, your credit history, the lenders competing for your kind of borrower. "Should I refinance?" is really "has enough moved since that day?" For a fuller picture of what a refinance actually is, start with the plain-English guide.

Five signals your loan is worth re-checking

• Your loan was arranged at the dealership. Dealer finance is signed quickly, often on the same afternoon as the car, and the pricing reflects that convenience. Loans that started life on a car yard are the single most common refinance candidates, not because dealers are villains, but because nobody compared.
• Your credit has improved since you signed. Lenders priced the person you were on application day. If defaults have aged off, your payment history has grown, or your income has steadied, a new lender assesses today's file, and today's file may deserve better terms.
• The repayments are straining. If each payday feels tighter than it should, refinancing can spread the remaining balance over a longer term to bring each repayment down. You'll usually pay more in total for that breathing room. It's a trade, and worth making with open eyes rather than by missing payments.
• The loan is carrying add-ons. Bundled payment protection, add-on insurance, and extras that landed in the contract at signing all cost money every week. A refinance replaces the whole contract, which means the passengers don't have to come along. Our guide to red flags in your current loan shows what to look for.
• You've never compared. If the loan you have is the only loan you've ever priced, you don't actually know whether it's good. You know it was available. A two-minute check answers the question either way, and "my loan is already sharp" is a perfectly good answer.

Three signals to stay put

• The balance is small or the finish line is close. With little owing or only months remaining, there isn't enough loan left for a better one to make a meaningful difference, and any fees eat what little there is.
• The break fee is big. Some contracts charge a meaningful early-repayment fee. If yours does, it goes on the cost side of the ledger, and sometimes it tips the whole decision. Here's how to find yours.
• Your credit has got worse. A weaker file usually attracts weaker offers. Keep the loan you have, rebuild the file, and revisit later. The option doesn't go anywhere.

The decision at a glance

Your situation	Leaning
Dealer-arranged loan, never compared	Check it
Credit improved since signing	Check it
Repayments straining the budget	Check it
Add-ons bundled into the contract	Check it
Small balance, under a year left	Probably stay
Large break fee in the contract	Run the maths first
Credit weaker than at signing	Stay and rebuild

Timing matters more than most people think

Car loan interest is charged on the balance you still owe, which means most of a loan's total interest is paid in its early stretch, while the balance is at its biggest. The practical consequence: the earlier in the term you switch to a cheaper loan, the more of the expensive stretch you skip. Waiting to "see the loan out a bit" usually means paying the costly part of the old loan and then switching for the cheap part, which is the trade backwards. If the signals above apply to you, they apply most strongly now.

How to run the maths

Three numbers decide it: what you still owe, what you pay each week or fortnight, and how many payments you have left. Multiply the repayment by the payments remaining and you know exactly what staying put costs. Put the same balance and term into the savings calculator and it shows what the picture could look like under 1%, 2%, and 3%-lower scenarios (an illustration, not a quote), but enough to tell you whether the question is worth asking. The real figures come from a lender assessing your actual file, and whether an offer beats your current loan depends on that assessment.

What checking costs you

Nothing, and about two minutes. The application starts with a soft check that doesn't appear on your credit file, and Leverage is free to use. The lender pays us a referral fee if a loan settles, and nobody pays anything if you don't switch. If you'd like the full mechanics before you start, here's the process start to finish.

Leverage Finance is a lead-generation referral service, not a lender. All lending decisions, rates, and terms are determined by the lender assessing your application. Nothing on this page is financial advice. It's general information about how refinancing works.
