What is the benefit of selecting a slightly higher time bracket for fixed deposits?

There are various time slabs available for making fixed deposits. In such a situation, there will also be different rates of interest that are offered for these time slabs. Slipping into a higher or lower time slab can increase the rate of return that is earned by the investor. So, there can be a position where the investor might earn 8% instead of 7.5% for just a few additional days of investment. The restriction here is that the absolute amount of interest earned will depend upon the time period of the deposit. So, for example, if the 6 month to 1 year time bracket has 8% rate then an investment for 6 months for Rs 10,000 will give the investor an earning of Rs 400 while the one-year investment for the same time period will give them Rs 800. While the rate remains the same the time of the investment results in the absolute difference that is witnessed.
