What is Flat Rate?

Flat rate is a simple interest calculation method where the interest is calculated on the original loan amount and remains constant throughout the loan term. The monthly installment stays the same, but the interest doesn't decrease as you pay down the principal. This method is commonly used in Indonesia and easier to understand, but results in higher total interest compared to effective rate.

What is Effective Rate (Anuitas)?

Effective rate, also known as anuitas or reducing balance method, calculates interest on the remaining loan balance. As you pay down the principal, the interest portion decreases while the principal portion increases. This results in lower total interest compared to flat rate. The monthly payment remains constant, but the composition changes over time.

Insurance Types Explained

TLO (Total Loss Only)

TLO insurance covers only total loss scenarios where the vehicle is stolen or damaged beyond 75% of its value. Premiums are typically 0.5-1.5% of car value annually. Cheaper option suitable for older vehicles or budget-conscious buyers.

Comprehensive (All Risk)

Comprehensive insurance covers all damages including minor scratches, dents, and major accidents. Premiums typically range from 1.05-4.02% of car value annually. Recommended for new cars or those seeking complete protection. Premium decreases as car depreciates.
