Frequently Asked Questions

What does a mortgage payment include?

Mortgage payments usually include principal and interest, and may include property tax and home insurance. This calculator shows all these components together for clearer cashflow planning.

How much down payment should I put?

A higher down payment reduces monthly payment and total interest, but you should still keep emergency reserves. Many borrowers optimize down payment vs liquidity rather than maximizing it.

Does a shorter tenure always save money?

Yes, shorter tenure usually lowers total interest significantly, but monthly payments increase. You should balance affordability and interest savings.
