We can run the calculations for you, show you live rates across multiple lenders, and help you apply — all at no cost to you. Use the FAQs below to get a clear picture of how UnionBank housing loan payments work, then see how much you could save by comparing rates through Nook.
A housing loan calculator estimates your monthly amortization by applying the loan's interest rate to your principal balance over your chosen loan term. You input three key figures: the loan amount, the fixed interest rate, and the repayment period in years. The calculator then uses an amortization formula to spread your payments evenly so that each monthly installment covers both interest and a portion of the principal.
For a UnionBank housing loan, the most commonly used rate for calculation purposes is the 1-year fixed rate of 7.00% p.a. After the fixed period ends, your rate will be repriced based on prevailing market conditions, so it's worth modelling different rate scenarios to understand your future payment range. Nook's calculator lets you do exactly that — input UnionBank's current rate and then compare it side-by-side with other banks to see which offers the lowest total cost over your loan term.
UnionBank currently offers a 1-year fixed rate of 7.00% p.a. for standard housing loans, and the same 7.00% p.a. applies to home equity loans. These rates are competitive within the Philippine market, particularly for borrowers who qualify under UnionBank's standard credit requirements.
It's important to note that the fixed rate applies only for the fixed period selected — after that, the rate is repriced. Borrowers should factor in potential rate movements when planning long-term budgets. For a deeper breakdown of UnionBank's fixed periods and how they affect your amortization over time, see our guide on UnionBank housing loan interest rates for 2026. Always verify the latest rates directly with UnionBank or through Nook, as rates are subject to change.
The standard formula for computing a fixed monthly amortization is: M = P × [r(1+r)^n] ÷ [(1+r)^n − 1], where P is the loan principal, r is the monthly interest rate (annual rate divided by 12), and n is the total number of monthly payments (years multiplied by 12).
For example, on a loan of 3,000,000 at 7.00% p.a. over 20 years: the monthly rate r = 0.07 ÷ 12 = 0.005833, and n = 240. Plugging these in gives a monthly amortization of approximately 23,260. Over the full 20-year term, total repayments would be around 5,582,400 — meaning total interest paid would be approximately 2,582,400. Using a calculator or asking Nook to run these numbers for you saves time and reduces the risk of manual errors, especially when comparing multiple rate scenarios.
UnionBank accepts housing loan applications across a wide range of property values, with loan amounts typically starting from 1,000,000. Loan terms generally range from 5 to 25 years, giving borrowers flexibility to choose a repayment period that balances monthly affordability against total interest cost. Longer terms reduce monthly payments but increase the total interest paid over the life of the loan.
The right combination of loan amount and term depends on your income, the property price, and how much of a down payment you can provide. UnionBank typically finances up to 80% of the appraised property value for standard purchases. Nook can help you model different loan amount and term combinations using UnionBank's actual rates so you can find the structure that works best for your situation.
UnionBank has accessible eligibility criteria compared to many Philippine banks. The minimum monthly income requirement is 30,000, and the maximum debt-to-income (DTI) ratio is 50% — meaning your total monthly debt obligations, including the new housing loan payment, should not exceed half of your gross monthly income.
In terms of employment, UnionBank accepts a broad range of borrower profiles: private employees, government workers, BPO industry employees, OFWs and seafarers, self-employed individuals, and licensed professionals. This makes UnionBank a practical option for many Filipino borrowers who may find other banks' requirements more restrictive. Age requirements and citizenship rules apply in the standard manner under Bangko Sentral ng Pilipinas guidelines.
UnionBank's housing loan program covers a comprehensive range of property-related purposes. Borrowers can apply for financing for the following: purchase of a ready-for-occupancy (RFO) unit, pre-selling property purchases, reselling of existing homes, new construction on a lot you already own, renovation of an existing property, home equity (cash-out against property value), and purchase of foreclosed properties.
This breadth of coverage makes UnionBank a versatile lender whether you're buying a brand-new condo, constructing a house, extracting equity for other financial needs, or even acquiring a foreclosed asset at a discount. Each loan purpose may have slightly different documentation requirements and loan-to-value ratios, so it's worth confirming the specifics for your situation before applying.

For context, if you are currently paying a rate of 9% or higher on an existing home loan, refinancing to UnionBank's 7.00% — or even better, to Nook's best available rate of 5.99% — could reduce your monthly payment significantly and save you hundreds of thousands of pesos over the remaining loan term. All figures are estimates; please verify with Nook or UnionBank directly.
Yes. UnionBank accepts refinancing applications from borrowers who currently have a home loan with another bank. Refinancing involves taking out a new loan with UnionBank (at its current rate of 7.00% p.a.) to pay off your existing mortgage, ideally at a lower rate than you are currently paying. If your current rate is 8%, 9%, or higher — which is common for loans originated several years ago — refinancing could meaningfully reduce both your monthly payment and total interest cost.
The refinancing process involves a new credit assessment, property appraisal, and standard documentation. Nook can guide you through the full process at no charge. We also encourage you to compare UnionBank against other lenders — our best available refinance rate is currently 5.99% p.a., which may result in even greater savings depending on your loan profile.

UnionBank's 7.00% p.a. 1-year fixed rate is broadly in line with other major Philippine banks, though specific rates vary by lender, loan amount, and borrower profile.
