Frequently Asked Questions

Financial Intelligence & Clarity

Understand the mathematical principles powering our decision models.

In the initial 5–10 years of a home loan, the bulk of every monthly EMI payment goes towards interest rather than principal repayment. By paying 1 extra EMI each year (or a small monthly top-up), 100% of that extra payment is deducted directly from your outstanding principal. As the principal drops, future compounding interest decreases permanently, shaving years of tenure and saving huge sums of money.
