Quarterly compounding turns 7% into 7.19% a year, because each quarter's interest earns interest too.

FD interest is taxed at your income tax slab rate, and banks deduct TDS once a year's interest crosses the threshold, so the return you keep is lower.

How this is worked out

A cumulative FD adds each quarter's interest to the deposit, so the next quarter's interest is earned on a larger balance. The maturity value is A = P × (1 + r/4)^(4t), where P is ₹10 lakh, r is 7% and t is 1 year.

If you choose a monthly payout instead, the interest is paid to your bank account as it accrues and does not compound. On ₹10 lakh at 7% that is about ₹5,833 a month, and you get exactly ₹10 lakh back at the end.

Tax changes the picture. Interest is added to your income and taxed at your slab rate each year, whether or not it is paid out. At a 30% slab, a 7% FD keeps roughly 4.90% after tax, below 6% inflation, which is why the inflation-adjusted value matters: ₹10.72 lakh in 1 year buys about what ₹10.11 lakh buys today.
