How to compare car loan offers in the Philippines
Car dealers often advertise a low monthly add-on rate that sounds cheaper than a bank rate. The two are not comparable. A flat rate keeps charging interest on the original amount while you pay it down, so the cost is far higher than the number suggests.
This calculator converts any quote into a real yearly rate so you can put a dealer offer next to a bank offer. It also shows total interest and the extra you pay over the cash price.

How the car loan estimate works
- Amount financed is the car price minus your down payment.
- With a flat rate, interest equals the amount financed times the rate times the years, and the payment is the total divided by the months.
- With a diminishing balance rate, interest is charged only on what you still owe, using the standard amortization formula.
- The real yearly rate is the diminishing balance rate that gives the same monthly payment, so you can compare any two offers.
Tips to save more
- Compare offers by the real yearly rate, not by the advertised monthly rate.
- A bigger down payment or a shorter term can cut interest sharply.
- Shop insurance separately instead of accepting the first package.
- Add fuel, parking and maintenance to the monthly payment before you decide.
