Let’s look at how the returns compare over two interest rate scenarios. Suppose you invested Rs 9 lakh in three equal parts in FDs of one, two and three-year tenures between January 2018 and December 2020 when the interest rates were falling (6.5 per cent, 6.0 per cent, and 4.7 per cent, respectively). In this case, you would have earned a combined interest amount of Rs 1,63,500 after the end of the third year. However, if you had booked the FD with a one-time investment for three years at 6.5 per cent, you would have made Rs 1,75,500. It shows that your returns would have fallen short by Rs 12,000 if you had used the laddering tool.
