For this loan, in order

The table computes each lender at both ends of its published range on the same amount and term; lenders whose published minimum, maximum or terms exclude this loan are left out rather than guessed at.

Every lender we hold whose published amounts and terms cover £20,000 over 36 months, ordered by best-case total repayable. Ties are broken alphabetically. Nothing else affects the order, and no position on this page is for sale. 17 lenders, checked 2026-09-18.

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 order above holds only under these conditions.

If your credit is mid-range rather than top, the order changes: at the top of the published ranges Metro Bank is lowest, not M&S Bank.
8 lenders publish a floor but no ceiling (M&S Bank, TSB, NatWest, Novuna Personal Finance), so their worst case cannot be computed and they may cost more than any figure here.
Do not decide yet if you might need £35,000 instead: at that amount the lowest floor is Nationwide at £38,187, not M&S Bank, because published maximums drop lenders out.

Who this is not for

This is not a list of the best lenders and it is not advice. It is every lender we hold whose published range covers this loan, in order of the published floor. We have not borrowed from them and we do not rate them; the rate you are offered is decided by the lender, not by this page.
