Frequently Asked Questions

Is it better to reduce EMI or reduce loan tenure?

Reducing tenure always saves significantly more interest because it curtails compounding over multiple future years.

Should I prepay loan or invest in mutual funds?

If your loan interest rate exceeds expected post-tax investment returns, prepaying the loan provides a guaranteed risk-free return.

Are there tax disadvantages to prepaying a home loan?

While Section 24(b) interest deduction drops slightly, saving real interest paid to the bank far outweighs minor tax perks.
