Asia United Bank vs Sterling Bank: Home Loan Overview

Asia United Bank (AUB) is a publicly listed universal bank in the Philippines with a growing retail banking presence, including home loan products for property purchases and refinancing. Sterling Bank of Asia, on the other hand, is a smaller thrift bank that has historically focused on consumer and SME lending, with home loans available but not as prominently marketed as its larger competitors.

For Filipino homeowners weighing these two institutions — whether for a new purchase or a refinance — the differences in product depth, rate competitiveness, and customer experience can be significant. Here's how they stack up.

Monthly Repayment Comparison

To illustrate the real-world impact of these rate differences, here's a sample monthly repayment calculation for a 3,000,000 peso home loan over a 20-year term:

Interest RateEstimated Monthly PaymentTotal Interest Paid
AUB at 8.00% p.a.25,0933,022,320
Sterling Bank at 9.00% p.a.26,9923,478,080
Nook Best Rate at 5.99% p.a.21,4842,156,160

At 5.99% p.a. versus AUB's 8.00%, a borrower with a 3,000,000 peso loan saves approximately 3,609 pesos per month and over 866,000 pesos in total interest over 20 years. Versus Sterling Bank at 9.00%, the savings are even more dramatic — over 1,321,000 pesos across the full loan term.

Fees and Charges

Both banks have broadly similar fee structures. The bigger variable is the interest rate, which over a 15-25 year term dwarfs any one-time processing or appraisal fee in terms of total cost impact.

Loan Features and Eligibility

AUB has a broader product suite and more experience handling OFW applications, which can be an advantage for overseas Filipino workers looking to refinance a property back home. Sterling Bank's home loan program is more limited in scope, and its rates tend to sit at the higher end of the market.

AUB has invested more in digital banking infrastructure, which can make the loan application and monitoring process somewhat more convenient. Sterling Bank's processes remain more traditional and branch-dependent, which may be a friction point for borrowers in areas without a nearby branch.

If you're currently paying 8% or more on your existing home loan — whether with AUB, Sterling Bank, or any other lender — refinancing should be a serious consideration. The question isn't just which of these two banks is better; it's whether either of them is the best option available to you right now.
