Answer

What is the effective interest rate?

The effective interest rate reflects the true annual cost once compounding and fees are included. It is usually higher than the nominal rate, and it is the fairest way to compare borrowing.

What it means

A nominal rate is the stated annual percentage; the effective rate adjusts it for how often interest compounds and, in broader use, for fees. Because interest charged monthly compounds through the year, the effective rate exceeds the nominal one. It is close in spirit to APR, which rolls fees in too.

What this means for your company

When you compare offers, the effective rate (or total repayable) is what counts — a lower nominal rate with monthly compounding and fees can cost more than a higher-looking simple rate. Use the true-cost calculator to level the field, and always ask for the total pounds repayable so no compounding or fee is hidden from you.

Frequently asked questions

Is the effective rate the same as APR?

They are close. APR is a standardised figure that includes compulsory fees; the effective rate primarily reflects compounding. Both aim to show the true annual cost, which is why either beats a bare nominal rate for comparison.

Why is my effective rate higher than the quoted rate?

Because interest compounds over the year and fees add to the cost. A 1% monthly rate is not 12% a year once compounding is included — it is slightly higher. Always compare on effective or total repayable.
