The Senior Citizens Savings Scheme (SCSS) is designed for seniors, aged 60 years and above, allowing them to invest money for an initial period of five years. The scheme offers a guaranteed quarterly interest on their investment. Currently, the interest rate for SCSS is 8.2 per cent, which is the highest rate available among all small savings schemes offered by the post office. A senior, whether retired, self-employed, or non-working, can open an SCSS account with a post office or bank and invest up to Rs 30 lakh. SCSS is like a fixed deposit (FD), booked at prevailing interest rates and which remains intact even if interest rates go down or up in the future.
