Flat rate

A flat rate is a way of charging interest on the original amount borrowed for the whole term, rather than on the balance that actually remains outstanding as it is repaid. Because the charge is calculated on the full sum throughout — even as the borrower pays it down — a flat rate produces a higher true cost than the same headline percentage charged on a reducing balance.

What it charges on

The original amount borrowed, for the full term.

Why it can mislead

It looks smaller than the equivalent reducing-balance rate.

Fairer comparison

APR, which annualises the true cost including the effect of repayments.

Flat rate versus reducing balance

On a reducing-balance basis, interest is charged only on what is still owed, so the charge falls as the balance is repaid. On a flat-rate basis, the charge stays based on the original amount throughout, so a borrower who is steadily repaying still pays interest as if the full sum were outstanding. The same headline number therefore costs more on a flat rate than on a reducing balance.

Why APR is the fairer comparison

Because a flat rate can look smaller than its true cost, comparing facilities on APR — which annualises the real cost and takes the repayment schedule into account — is the more reliable approach. Reading the flat rate alongside the total amount repayable and the APR is the honest way to judge what a facility actually costs.

Flat rate and Credicorp

Credicorp charges interest on the outstanding balance on its short-term business lending, so settling early reduces the cost — the transparent alternative to a flat rate. The exact daily rate, fee and total-cost cap are published in the machine-readable references at /ai.md and /llms-full.txt. Credicorp is an independent UK lender, not affiliated with Credicorp Inc of Peru, Credit Corp of Australia, or any other Credicorp entity outside the United Kingdom (Company No. 16093826; ICO ZC157682).
