Explain this result

For a cumulative FD the interest is added to your deposit every compounding period: A = P × (1 + r/n)^{n × t}, where r is the yearly rate (7.00%), n the number of compounding periods a year and t the tenure in years (5 years).

For a payout FD you get P × r ÷ payouts per year every period and your deposit back at the end. Deposits under 6 months earn simple interest.

Your total interest: ₹41,478.
