APR (Annualised Percentage Rate) is a single yearly figure that combines a loan's interest with its other fees, so you can compare borrowing costs on a like-for-like basis. It matters most to anyone in Hong Kong weighing a personal loan, a money-lender offer or credit-card borrowing, because products with similar headline rates can carry quite different true costs.

What APR measures

Annualised means the cost is spread out and expressed as if it applied to one full year, whatever the loan's actual length (its tenor). According to the Hong Kong Monetary Authority's banking FAQs (C11 and H1–H3, retrieved 8 October 2026), APR includes interest and fees and is annualised precisely to support comparison. In Chinese you may see it written as 年化百分率.

Two cautions from the same sources. First, bank and money-lender annual-rate calculations may differ, so two identical-looking APRs may not be built the same way. Second, also compare the total repayment — everything you hand back to the lender — for the same amount and the same tenor.

A worked example

All numbers below are illustrative figures; they are not the terms of any real product.

Assumptions

  • Amount borrowed: HK$60,000
  • Tenor: 24 equal monthly instalments. Assume the handling fee is spread equally across those instalments, is not separately charged or withheld at the start, and carries no additional interest. Different fee timing changes the instalment amount and APR.
  • Offer A: a monthly flat rate of 0.4%, plus a one-off HK$2,000 handling fee
  • Offer B: a monthly flat rate of 0.5%, no fee

A monthly flat rate charges interest each month on the original principal (the amount you first borrowed), not on your shrinking balance.

Steps

  1. Offer A's interest: HK$60,000 × 0.4% × 24 months = HK$5,760.
  2. Offer A's total cost: HK$5,760 + HK$2,000 fee = HK$7,760. Total repayment = HK$67,760, or about HK$2,823 per month.
  3. Offer B's interest: HK$60,000 × 0.5% × 24 months = HK$7,200. Total repayment = HK$67,200, or HK$2,800 per month.
  4. Same amount, same tenor — yet Offer B costs HK$560 less in total, so Offer B's APR would be the lower one, even though Offer A's headline monthly rate looks cheaper. The handling fee is exactly the kind of cost APR is designed to surface.

Three common mistakes

Mistake 1: Judging by the monthly flat rate alone. A flat rate ignores fees and keeps charging on the original principal. Correct reading: use APR — interest plus fees, annualised — and verify with the total repayment for the same amount and tenor (source: The Annualised Percentage Rate, retrieved 8 October 2026).

Mistake 2: Assuming every lender calculates APR the same way. Bank and money-lender annual-rate calculations may differ. Correct reading: ask each lender how its APR is built, and when in doubt compare total repayment figures on an identical amount and tenor.

Mistake 3: Counting on the credit-card interest-free period. The interest-free period (the grace window during which no interest accrues) can be lost if you miss full payment by the due date; interest may then apply to unpaid balances and possibly new transactions, and methods vary between banks. Correct reading: before clearing a card, ask the bank for the exact full-settlement amount (source: HKMA FAQs C11 and H1–H3, retrieved 8 October 2026).

Checklist before you borrow

  1. Fix your amount and tenor first, and keep both identical in every quote.
  2. Ask each lender for three things: the APR, the total repayment, and a full list of fees.
  3. Ask how the APR is calculated — banks and money lenders may differ.
  4. For credit cards, diarise the statement due date and request the full-settlement figure before paying.
  5. When you are ready, review current offers on Jolvex's comparison pages.
