Frequently Asked Questions

Does this include processing fees?

No, this calculator only computes interest based on the principal and rate. Fees are usually extra.

Is this for flat rate or reducing balance?

This generally calculates interest on the total principal (Flat Rate estimate) for simplicity. Bank loans often use reducing balance.

How can I reduce my interest?

You can reduce total interest by choosing a shorter tenure or making a larger down payment to reduce the principal.
