Frequently Asked Questions
Quick answers to common questions
How is FD interest calculated?+
Cumulative FD uses A = P(1 + r/n)^(nt). Payout FDs pay periodic interest on principal.
What is monthly vs quarterly payout?+
Interest is paid out each month or quarter; principal is returned at maturity. Total received = principal + all payouts.
What is EAR?+
Effective Annual Rate shows the true yearly yield after compounding frequency.
Is FD interest taxable?+
Yes. Interest is added to income and taxed per your slab.
When is TDS deducted on FD?+
Banks deduct 10% TDS if annual interest exceeds ₹40,000 (₹50,000 for senior citizens) under Section 194A.
What is senior citizen benefit?+
Toggle adds 0.5% to the entered rate — typical bank practice for 60+ customers.
Can I break an FD early?+
Usually yes with a penalty of 0.5–1%. Tax-saving 5-year FDs cannot be broken early.
Which compounding is best?+
More frequent compounding (monthly) yields slightly higher returns than yearly for the same rate.
