How that is worked out

amount received = the amount you want in your account (10,000 on most pages) amount signed for = amount received / (1 - origination fee %) monthly rate = APR / 12 (United States) or (1 + APR)^(1/12) - 1 (United Kingdom) monthly payment = amount received x monthly rate / (1 - (1 + monthly rate)^(-months)) total repayable = monthly payment x months cost of credit = total repayable - amount received cost per 1,000 = cost of credit / (amount received / 1,000)

Nothing else is added. The APR already includes the origination fee by law in both markets, so the payment is worked out on the amount you actually receive, at the APR, over the term — which is exactly how the lender's own representative example is built. The fee shows up as the larger amount you sign for, and the interest on it is inside the APR. Late fees, optional insurance and early-settlement charges are not in any figure on this site, because they depend on what happens after you sign. Best case uses the lowest published APR and the lowest published fee; worst case the highest of each. The full method is at Method.

Where does the answer change?

The ranking above holds only under the conditions listed here.

The answer flips with your credit. At the bottom of the ranges Santander is cheaper; at the top the other one is. A wide range and a high fee at the top are usually why.
Do not decide yet until you hold both offers: Santander stays ahead only if the APR it actually offers you is below 6.50% — HSBC UK's published floor, which is the point where its £11,003 best-case total is matched on this loan. An offer above that number reverses this page.

Who this is not for

This compares published ranges and nothing else. It is not a judgment about service, approval odds or speed, and we have not borrowed from either. If the two totals are close, this page will not decide it for you and should not.
