A Beginner's Guide to Interest Rates and APR in Philippine Lending

By Maria Santos, Financial Writer • July 02, 2026 • ⏱ 4 min read

When comparing loan options, the terms 'interest rate' and 'Annual Percentage Rate (APR)' can be confusing. Many borrowers focus solely on the monthly interest rate, only to be surprised by additional fees when signing their loan documents. Understanding the difference between interest rates and APR is crucial to calculating the true cost of borrowing.

Interest Rate vs. Annual Percentage Rate (APR)

The interest rate is the basic cost of borrowing the principal amount, expressed as a percentage. It does not include any other charges.

The Annual Percentage Rate (APR) represents the total annualized cost of the loan. It includes the interest rate PLUS any additional fees, such as processing fees, service fees, or insurance costs. For this reason, the APR is the most accurate metric to use when comparing the cost of different loan products.

The Truth in Lending Act (R.A. 3765)

In the Philippines, the Truth in Lending Act protects borrowers from deceptive financial practices. Under this law, lenders are strictly required to provide you with a written Disclosure Statement before you sign any loan agreement. This statement must clearly detail:

The principal loan amount.
All non-interest fees and charges (such as processing or administrative fees).
The nominal interest rate.
The total finance charge (interest + fees).
The effective Annual Percentage Rate (APR).

By reviewing the APR and disclosure statement of each offer, you can compare different lenders fairly and choose the option that fits your budget.
