Amortization Calculator Philippine Peso

Reviewed by Calculator Editorial Team

This amortization calculator helps you determine monthly payments for loans denominated in Philippine Peso (PHP). It provides a detailed amortization schedule showing how much of each payment goes toward principal and interest over the life of the loan.

What is Amortization?

Amortization is the process of paying off a loan in regular installments over time. Each payment includes both principal (the original amount borrowed) and interest (the cost of borrowing). The goal is to gradually reduce the loan balance until it's fully paid off.

Amortization schedules are essential for understanding loan repayment plans. They show exactly how much of each payment goes toward reducing the principal versus paying interest. This helps borrowers budget effectively and plan for future financial obligations.

How to Use This Calculator

Using this amortization calculator is simple:

  1. Enter the loan amount in Philippine Peso (PHP)
  2. Specify the annual interest rate (APR)
  3. Choose the loan term in years
  4. Click "Calculate" to generate the amortization schedule

The calculator will display:

  • Monthly payment amount
  • Total interest paid over the loan term
  • Complete amortization schedule
  • Visual chart showing principal and interest breakdown

Formula Used

The monthly payment (M) is calculated using the standard loan amortization formula:

M = P [ r(1+r)^n ] / [ (1+r)^n - 1 ]

Where:
  • M = Monthly payment
  • P = Principal loan amount
  • r = Monthly interest rate (annual rate divided by 12)
  • n = Number of payments (loan term in years × 12)

This formula accounts for the fact that each payment includes both principal and interest, with the interest portion decreasing as the principal balance decreases over time.

Worked Example

Let's calculate an amortization schedule for a PHP 1,000,000 loan at 12% annual interest for 5 years:

  1. Principal (P) = PHP 1,000,000
  2. Annual interest rate = 12%
  3. Monthly interest rate (r) = 12% ÷ 12 = 1% = 0.01
  4. Number of payments (n) = 5 years × 12 = 60 months

Plugging these values into the formula:

M = 1,000,000 [ 0.01(1+0.01)^60 ] / [ (1+0.01)^60 - 1 ]

M ≈ PHP 22,833.50 per month

The first payment would include approximately PHP 10,000 in interest and PHP 12,833.50 in principal, reducing the balance to PHP 987,166.50. Each subsequent payment would have slightly less interest and slightly more principal until the loan is fully paid off after 60 months.

Frequently Asked Questions

What is the difference between APR and APY?

APR (Annual Percentage Rate) is the simple annual interest rate charged on a loan, while APY (Annual Percentage Yield) is the effective annual rate that includes compounding interest. APY is always higher than APR for loans with compounding interest.

How does prepayment affect amortization?

Making extra payments or prepaying a loan can reduce the total interest paid and shorten the loan term. However, it may also increase the monthly payment amount for the remaining balance. Always check how prepayment affects your specific loan terms.

What happens if I miss a payment?

Missing a payment can result in late fees, additional interest charges, and potential damage to your credit score. It may also trigger a repayment plan where the lender adjusts your payment schedule. Always make payments on time to avoid these consequences.
