Tips for comparing loans:Hong Kong banks often advertise "monthly flat rates", but APR is the standard for comparing true borrowing costs. APR includes interest and related fees; the higher the figure, the more expensive the loan.

Understanding the Annual Percentage Rate (APR)

In Hong Kong's lending market, banks, finance companies and credit card issuers often promote \"monthly flat rates\" or \"handling fees\", but these figures may not reflect the true cost of borrowing. The Annual Percentage Rate (APR) is a standardised measure that includes interest, fees and other borrowing costs, allowing borrowers to compare the real cost of different loan products directly. Under HKMA guidance and industry practice, licensed institutions must disclose borrowing costs as APR to protect consumers.

The key difference between APR and the \"monthly flat rate\" is that the flat rate applies a fixed percentage to the original loan amount and does not decrease as the principal is repaid, so the APR is usually much higher than the flat rate. For example, a personal loan with a 0.5% monthly flat rate may have an APR close to or even above 10%. Looking only at the flat rate and ignoring the APR can easily lead to underestimating the total repayment burden.

FAQs

What is the difference between APR and monthly flat rate?

The monthly flat rate is a fixed interest ratio calculated on the loan amount and does not decrease as the principal is repaid. APR includes interest and various fees, giving a more accurate reflection of borrowing cost.

Why is APR higher than the monthly flat rate?

Because APR converts handling fees, cash rebates and other borrowing costs into an annual rate, while the monthly flat rate only reflects the headline interest expense.

Which rate should I look at when comparing loans?

You should use APR as the comparison benchmark because it is a standardised measure of borrowing cost.

Does APR vary with personal credit status?

Yes. The APR advertised is often the best available rate. The actual APR you are approved for will be adjusted according to your credit rating, income and repayment ability.

Is the APR calculated by this calculator accurate?

The calculator estimates based on the information you enter. The actual APR is still subject to the lender's final approval. Confirm all charges with the lender before applying.
