FD Calculator

Cumulative FD maturity = Principal × (1 + r / 4)^(4 × t), where r is annual rate (compounded quarterly) and t is years. Non-cumulative FD interest = Principal × r × t (simple interest) paid at the chosen frequency. Calculator applies both formulas.

TDS under Section 193A is 10% on FD interest exceeding ₹40,000 from banks and ₹5,000 from post office in a financial year. For NRIs, TDS is 30% under Section 195 unless DTAA rate applies. Senior citizens can submit Form 15H; others use Form 15G to claim nil TDS.

Senior citizens (60+) typically get a 0.5-0.75% higher FD rate than the regular card. PSU banks offer 7.5-8.5% for 1-5 year senior-citizen FDs; private banks offer 7.25-8.75%. Calculator applies the senior citizen premium if the input matches.
