Advertised loan rates almost always carry the words “from” or “representative”. That is not marketing sleight of hand so much as a description of how lending works: the rate is not a price on a shelf, it is a calculation about you. Understanding the inputs is the difference between accepting a quote and improving it.
Risk-based pricing, in one sentence
The rate you are offered is roughly the lender's own cost of money, plus their operating costs and margin, plus a premium for the risk that you will not repay. The first part moves with benchmark rates set by central banks and is the same for everyone. The last part is entirely about your file.
The five inputs that matter most
Credit score. The single biggest lever. Lenders use it as a shorthand for the likelihood of repayment, and the difference between tiers is not gradual — it is stepped. Moving from one band to the next can change your rate materially, while gaining ten points inside the same band changes nothing at all.
Debt-to-income ratio. Your total monthly debt payments, including housing, measured against gross monthly income. Most lenders want to see this under 45%, and some want it under 35%. This is the input borrowers most often overlook, because it can disqualify an application that a good credit score would otherwise carry.
Income stability. Not just how much, but how predictable. Several years with one employer, or two full years of self-employed accounts, reads as lower risk than the same income earned in a role started last month.
Loan size and term. Longer terms and larger amounts usually attract higher rates, because there is more time for something to go wrong. This is why stretching a loan to reduce the monthly payment often increases the total cost twice over — more months, and a higher rate on each of them.
Whether the loan is secured. A loan backed by an asset prices lower than an unsecured one, because the lender's downside is limited. The trade-off is real: the asset is genuinely at risk.
Compare APR, not the headline rate
The interest rate describes the cost of borrowing the money. The APR includes compulsory fees, such as arrangement or origination charges, and is therefore the number that allows two offers to be compared. A loan at a lower rate with a 5% origination fee can easily cost more than one at a higher rate with none.
Where fees are deducted from the amount advanced rather than added to the balance, check what actually lands in your account. Borrowing 10,000 and receiving 9,500 means you are paying interest on money you never had.
What genuinely improves the offer
- Check your credit file before applying. Errors are common and take weeks to correct — but they are corrected free of charge, and a single wrongly recorded default can move you a whole tier.
- Reduce the balance, not just the payment. Credit utilisation feeds directly into scoring; paying a card down below roughly a third of its limit tends to show up faster than most other actions.
- Use pre-qualification, not full applications. Soft checks let you see indicative offers without leaving a footprint. Several hard searches in a short period looks like distress borrowing.
- Ask for a shorter term. Counter-intuitive, because the monthly payment rises — but the rate usually falls, and the total interest falls further.
- Borrow what you need. Rounding up “while you are at it” raises the amount, the term and often the rate band.
When the answer is no
A decline is not always about the score. It is frequently affordability — the lender's model concluded the payment does not fit the income — and that is worth knowing, because reapplying elsewhere at the same amount will produce the same result. Ask what the reason was; regulated lenders will tell you.

The short version
The lender is pricing uncertainty. Anything that reduces uncertainty — a longer employment record, a lower debt-to-income ratio, a shorter term, a smaller amount, security — reduces the rate. Anything that increases it does the opposite. That is the whole model.
