What's the formula for FD maturity with compounding?

Maturity A = P × (1 + r/n)^(n×t), where P is principal, r is annual rate (decimal), n is compounding frequency per year, and t is tenure in years (including partial years).

How are monthly/quarterly payouts handled?

In non-cumulative deposits, interest is paid out periodically without reinvestment. We approximate payouts using simple interest P×r×t and show the periodic payout estimate.

Does this include TDS?

You can simulate TDS (with/without PAN) and thresholds for seniors/non-seniors. Actual TDS depends on bank and tax rules; consult your bank and tax advisor.
