Paying insurance monthly: the interest charge hiding in your renewal
Monthly instalments often carry 20%+ APR. How to find the rate on your renewal and cheaper ways to spread the cost
Spreading car, home or pet insurance over 12 months feels like a small convenience, but it is usually a loan, and the interest rate is often higher than a credit card. This guide shows you where the APR is printed, what it adds to a typical premium and two ways to spread the cost that do not charge 20% or more. Information only, not personal advice.
Why monthly costs more
When you pay monthly, the insurer (or a finance company acting for it) lends you the annual premium and you repay it in instalments plus interest. Some insurers also add a set-up or arrangement fee, and a few charge a higher underlying premium to monthly customers. All of it is legal, and all of it must be disclosed, but the disclosure is easy to miss.
Interest rates on premium finance are typically in the range of 20% to 40% APR. That is higher than the average credit card and far higher than what you would earn on the same money in a savings account.
What it adds up to
| Annual premium | Rough extra cost at 20% APR | At 30% APR |
|---|---|---|
| £400 | About £40 | About £60 |
| £700 | About £70 | About £100 |
| £1,200 | About £120 | About £170 |
These are approximate because the interest is charged on a reducing balance over the year, so the true cost is a little less than a flat percentage of the premium. The point stands: monthly can add a tenth or more to your bill.
How to check the APR on your renewal
Insurers must show the cost of paying monthly before you agree to it. Look for:
- A line on the renewal letter or quote page reading "representative APR" or "APR", usually next to the monthly amount.
- The "total amount payable" for monthly against the annual figure. The difference is what the credit costs you.
- Any "credit arrangement fee" or "instalment fee" listed separately.
- A separate credit agreement document, often emailed after you buy. This is the loan.
If the APR is not obvious on a comparison site listing, click through to the insurer's quote, or phone and ask. The total-amount-payable comparison is the one that matters, because it captures fees as well as interest.
Cheaper ways to spread the cost
Pay annually on a 0% purchase credit card. If you have or can get a card with a 0% period on purchases, paying the full premium and clearing it in 12 equal chunks costs nothing in interest, provided you never miss a payment and clear it before the 0% ends. Most insurers accept credit cards for annual payment without a surcharge, but check first. A purchase over £100 on a credit card also gets Section 75 protection.
Save ahead. Open a separate easy-access savings pot and set a standing order for one-twelfth of next year's premium. By renewal you have the money and have earned interest on it rather than paid it. This is the cheapest option of all, and it works for every renewal from then on.
Ask your bank. Some current accounts offer a cheaper arranged overdraft or a short personal loan at a lower rate than premium finance. Compare the APR before assuming.
What to do next
- Find the APR and total amount payable on every insurance renewal you have.
- If you can pay annually, do. If not, put the premium on a 0% card and set a fixed monthly repayment.
- Start a monthly savings pot today for next year's renewal.
- Compare the monthly cost across insurers as well as the annual cost, because the interest rate varies between them. Check a comparison site for today's quotes.
