Personal Loan Calculator (Philippines)
Estimate your monthly payment and total interest — and see the real cost of an add-on (flat) rate versus a diminishing-balance rate.
Compute your monthly amortization
| Loan amount | |
|---|---|
| Total interest | |
| Total amount payable |
Estimate only. Diminishing uses your annual rate (standard for home and most bank loans). Add-on / flat uses a monthly rate and charges interest on the full amount the whole term — it looks cheaper than it is, so the same number as a diminishing rate would cost much more. Actual loans include fees and insurance not shown here.
Watch out for "add-on" rates
Many lending apps and salary loans advertise a low-sounding monthly add-on rate (e.g. "1.5% per month"). That charges interest on the full original amount for the entire term — so a 1.5% monthly add-on is roughly equivalent to a 30%+ effective annual rate, not 18%. Switch the interest type above to compare the same number both ways and you'll see the gap.
Before you borrow
- Ask whether the rate is add-on or diminishing — it changes the true cost a lot.
- Check the all-in cost: processing fees, disbursement fees, and penalties, not just the monthly rate.
- Borrow only what your take-home pay comfortably covers.
