FAQs

Compliance & Calculations

What is reducing balance amortization? expand_more

Reducing balance amortization means that interest is calculated only on the remaining outstanding principal amount, not the initial loan principal, saving you massive interest charges over the tenure.

How can I reduce my total loan interest liability? expand_more

You can reduce your total interest liability by opting for a shorter tenure, making regular part-prepayments, or using balance transfer facilities to switch to a lower interest rate.

Does prepaying my home loan attract penalties in India? expand_more

Under RBI regulations, individual borrowers with floating interest rate home loans do not attract any prepayment penalties from banks or financial institutions.

Understanding Step-Up SIP

A Step-Up SIP (also known as a Top-Up SIP) is a method where you automatically increase your monthly SIP contribution by a fixed percentage or amount every year. As your income grows, your investments should too.

Why Step-Up SIP is Better Than Normal SIP

Inflation silently erodes your purchasing power. If you continue investing the exact same amount for 20 years, the real value of that monthly investment drops significantly over time. A Step-Up SIP counteracts inflation and drastically accelerates your wealth creation trajectory without putting heavy pressure on your current finances.
