Why your first payment is mostly interest
A fixed-rate loan in the Philippines is usually paid in equal monthly amounts, but those equal payments hide a moving split. Interest is charged on whatever you still owe, so in month one the balance is at its largest and interest takes the biggest share. As you chip away at the principal, the interest portion shrinks and more of each fixed payment goes to paying down the loan. The total payment never changes, but its makeup flips over the life of the loan.
That is the entire purpose of this schedule. It takes your loan amount, annual rate, and term, computes the level monthly payment, then walks month by month showing exactly how much is interest, how much is principal, and what you still owe afterward. By the final row the balance lands on zero, and the tool clears any rounding drift on the last payment so it ties out cleanly.
Knowing the split is genuinely useful in the Philippines, not just academic. It tells you how much of your loan you have actually paid down at any point, which matters if you plan to sell a financed car, refinance to a cheaper rate, or settle the loan early. Because so little principal is repaid in the first year, the payoff balance early in a loan is often much closer to the original amount than borrowers expect, and the schedule shows you the real figure rather than a rough guess.
Reading the schedule month by month
Use the default loan to see the pattern: PHP 500,000 borrowed at 12 percent a year over 24 months. The level payment works out to about PHP 23,537 every month. Here are the first three rows and the last, so you can watch the interest portion fall as the principal portion rises.
| Month | Payment | Interest | Principal | Balance |
|---|
Across all 24 months the interest adds up to about PHP 64,882, so you repay roughly PHP 564,882 in total on a PHP 500,000 loan. The chart shows the crossover clearly: the interest bar starts high and falls to almost nothing, while the principal bar starts lower and grows until it makes up nearly the whole payment.
Who this schedule is for
This tool suits anyone holding or about to take a fixed-rate, equal-payment loan: a personal loan, a financed car, an appliance instalment plan, or a housing loan in its fixed period. It is most useful before you sign, when you can still compare offers, and at any point when you want the true payoff balance rather than a guess. It is less suited to credit cards, which charge interest differently and rarely follow a fixed schedule, and to loans with variable rates that reset, where the payment changes over time. For a steady term loan, though, the schedule below is exactly how the bank computes your repayment, and seeing it laid out makes a multi-year commitment far easier to judge.
A Philippine cost the schedule does not show
This calculator covers the repayment mechanics, but a real loan agreement in the Philippines can carry a documentary stamp tax on the debt instrument itself. As a rough guide it is often quoted as about PHP 1.50 for every PHP 200 of the loan, which is roughly 0.75 percent of the amount borrowed, frequently passed on to the borrower at signing. On a PHP 500,000 loan that points to something in the region of PHP 3,750 as a one-off. Treat that figure as an illustration of how the charge is structured, not a certified rate, and confirm what actually applies to your loan with your lender and the Bureau of Internal Revenue (BIR), since exemptions and treatment vary by loan type.
Will my real bank statement match this schedule exactly?
Close, but expect small differences. Lenders round to the centavo in their own way, may charge fees or insurance bundled into the monthly figure, and some use slightly different day-count conventions. This schedule assumes a clean monthly interest charge on the declining balance with no add-on fees, which is the textbook structure. Use it to understand the principal-and-interest split, then reconcile against your bank's official amortization table for the exact centavos.
How do I shorten the schedule without changing the rate?
Pay more than the required amount, and direct the extra to principal. Because interest is charged on the balance, every peso of early principal repayment removes future interest and pulls the payoff date forward. A shorter stated term does the same thing from the start by raising the monthly payment. If you want to see the saving from extra payments rather than a flat schedule, a prepayment calculator answers that directly.
