Pag-IBIG Housing Loan Calculator
Pag-IBIG Loan Estimate
What Is the Pag-IBIG Housing Loan Calculator?
The Pag-IBIG Housing Loan Calculator is a fixed-rate loan estimation tool. It calculates the expected monthly amortization for a selected loan amount and repayment period. It also estimates the total interest payable, total amount to pay, applied interest rate, and minimum monthly net disposable income based on a 35% payment rule.
The Pag-IBIG housing loan calculator estimates the monthly payment for a fixed-rate housing loan using the loan amount, repayment period, and a rate chosen from the calculator’s built-in pricing tiers. It also shows total interest, total repayment, and the estimated net disposable income needed under a 35% payment rule.
This calculator can help prospective borrowers compare different loan sizes and repayment periods before applying. Its results are estimates only. They do not represent loan approval, a final Pag-IBIG quotation, or a complete list of borrowing costs.
How the Pag-IBIG Housing Loan Calculator Formula Works
The calculator first selects an annual interest rate based on two factors: the desired loan amount and the repayment period. It then converts that annual percentage rate into a monthly rate and applies the standard fixed-rate amortizing loan formula.
- M is the estimated monthly amortization.
- P is the desired loan amount in Philippine pesos.
- r is the selected annual interest rate divided by 100 and then divided by 12.
- n is the repayment period in years multiplied by 12 months.
The calculator uses the monthly amortization to produce three additional results:
Here, T is the total amount to pay, I is the total interest payable, and NDI is the estimated minimum monthly net disposable income.
Worked Example
Suppose you enter a loan amount of ₱1,000,000 and a repayment period of 20 years. The amount falls within the ₱600,001 to ₱1,200,000 tier. A 20-year term falls within the 16-to-20-year band, so the calculator applies a fixed annual rate of 9.375%.
- The number of payments is 20 × 12, or 240 monthly payments.
- The monthly rate is 9.375% ÷ 100 ÷ 12, or 0.0078125.
- The formula produces an estimated monthly amortization of ₱9,239.84.
- The estimated total amount to pay is ₱2,217,560.91.
- The estimated total interest is ₱1,217,560.91.
- The estimated required monthly net disposable income is ₱26,399.53.
Displayed peso amounts are formatted with commas and two decimal places. The calculation itself uses the full unrounded monthly payment before formatting the final results.
How to Use the Pag-IBIG Housing Loan Calculator: Step by Step
- Enter your Desired Loan Amount in Philippine pesos. The amount must be greater than zero and cannot exceed ₱6,000,000.
- Enter the Repayment Period in years. The calculator accepts a term from 1 to 30 years.
- Select Calculate. The tool will identify the applicable rate tier and calculate the estimated payment.
- Review the Estimated Monthly Amortization and the summary of the loan amount, term, rate, and monthly payment.
- Check the breakdown for the applied interest rate, total interest payable, total amount to pay, and required minimum monthly income.
- Select Reset to clear both input fields and hide the current results.
The monthly amortization is the estimated amount paid each month for principal and interest. Total interest shows the estimated borrowing cost over the full term. Total amount to pay combines principal and interest. The income figure estimates the net disposable income needed for the payment to equal 35% of that amount.
What Your Pag-IBIG Loan Estimate Means
How the Calculator Selects the Interest Rate
The tool does not ask you to enter an interest rate. Instead, it selects one from the following table coded into the calculator. These rates are stored directly in the page and are not retrieved from a live pricing source.
| Loan Amount | 1–5 Years | 6–10 Years | 11–15 Years | 16–20 Years | 21–25 Years | 26–30 Years |
|---|---|---|---|---|---|---|
| ₱0 to ₱600,000 | 5.375% | 6.375% | 7.375% | 8.375% | 9.375% | 10.375% |
| ₱600,001 to ₱1,200,000 | 6.375% | 7.375% | 8.375% | 9.375% | 10.375% | 11.375% |
| ₱1,200,001 to ₱6,000,000 | 7.375% | 8.375% | 9.375% | 10.375% | 11.375% | 12.375% |
A Longer Term Can Change Both the Rate and Total Cost
A longer term spreads repayment across more months, but the calculator also applies a higher rate as the term moves into a new band. This means a longer repayment period may reduce or change the monthly payment while increasing the total interest paid over the life of the loan.
Important Limits and Excluded Costs
The estimate excludes mortgage redemption insurance, processing fees, and appraisal costs. It also does not calculate taxes, penalties, late charges, changing rates, early payments, or other expenses. Actual loan terms may vary based on current Pag-IBIG policies, borrower eligibility, property evaluation, documentation, and other requirements.
The calculator is specific to a Philippine Pag-IBIG housing loan and uses Philippine pesos. It is not a calculator for a U.S. mortgage, Federal Housing Administration loan, Department of Veterans Affairs loan, or other American lending program.
The loan amount field allows decimal values, but the coded rate tiers contain whole-peso boundaries. An amount between ₱600,000 and ₱600,001, or between ₱1,200,000 and ₱1,200,001, may not match a rate tier. The repayment period is read as a whole number of years.
Frequently Asked Questions
What does a Pag-IBIG housing loan calculator calculate?
It calculates an estimated monthly amortization using the desired loan amount, repayment period, and a fixed rate selected from the tool’s built-in tiers. It also displays the applied rate, total interest, total repayment amount, and estimated minimum net disposable income under the calculator’s 35% rule.
How is the Pag-IBIG housing loan interest rate selected?
The calculator selects the rate automatically based on the loan amount and repayment period. Loan amounts are divided into three tiers, while terms are divided into six bands ranging from 1–5 years through 26–30 years. The matching row and column determine the applied fixed rate.
How accurate is this Pag-IBIG housing loan calculator?
The calculator accurately applies the formula and rate table contained in its code, but the result remains an estimate. It does not use live rates or review borrower eligibility. Actual payments and approval terms may differ because of updated policies, insurance, fees, property details, and borrower information.
How much income do I need for a Pag-IBIG housing loan?
The calculator estimates required monthly net disposable income by dividing the monthly amortization by 0.35. This assumes the payment should not exceed 35% of net disposable income. The result is only an estimate and does not confirm qualification, affordability, or approval under actual lending rules.
Does the calculator include Pag-IBIG insurance and fees?
No. The displayed results exclude mortgage redemption insurance, processing fees, and appraisal costs. The calculator only uses the loan principal, selected fixed interest rate, and repayment period in its amortization calculation. Your actual borrowing cost may therefore be higher than the estimated total shown.
What is the maximum loan amount and repayment period?
The calculator accepts a maximum desired loan amount of ₱6,000,000 and a repayment period of up to 30 years. The amount must be greater than zero, and the term must be at least one year. Entries outside these limits produce an alert instead of a result.
Is this calculator for U.S. mortgages?
No. This calculator is designed around Philippine Pag-IBIG housing loan pricing tiers and displays all money values in Philippine pesos. A person living in the United States may use it to review a Philippine loan, but it should not be used to estimate payments for an American mortgage.
