You are not Factoring in the EMI's Which you are paying. You won't see any benefit in doing this if you are not able to generate at least 15% (Considering the intrest is paid Monthly)

At 8.5% Yearly Rate, You would net make ~Rs118 after factoring in the EMI's which you would be paying.
If you are able to get 1% CB on The Final Paid Amount then that would be your only profit.
I don't see any point in doing this with FD. Moreover You can't even claim the intrest Paid as Deduction if you are putting in FD. And Add 30% The Tax Amount on the intrest Earned.
What You Can Do:
You can't generate any return using FD on the borrowed amount. If you want to make any return them You have to be Risk Taking and invest it in Equity.
There are 2 Benefits in this:
(1) The Entire Interest Amount can be Deducted as Cost Of Acquisition. So That Means Rs 61250 Can be claimed. Which Further Means That You are Directly Saving 61250*15% = Rs 9188 If you made any STCG with the invested amount.
You can even claim the interest paid in Section 57(iii)
(2) You would be paying Reduced Tax. 15% STCG As Compared to 30%
9188 + 9362(1% CB Amount) = Rs 18550
So You are already up With Rs 18550 If you managed to make a profit in a Year.
Don't do any F&O, Invest in plain Stocks. Lower Risk (Still Risk😂) And Your Only Chance of Getting Return. If you don't know anything about Stock Market. Then Kindly don't try to do this.
