Quick answers to common questions
Cumulative FD uses A = P(1 + r/n)^(nt). Payout FDs pay periodic interest on principal.
Interest is paid out each month or quarter; principal is returned at maturity. Total received = principal + all payouts.
Effective Annual Rate shows the true yearly yield after compounding frequency.
Yes. Interest is added to income and taxed per your slab.
Banks deduct 10% TDS if annual interest exceeds ₹40,000 (₹50,000 for senior citizens) under Section 194A.
Toggle adds 0.5% to the entered rate — typical bank practice for 60+ customers.
Usually yes with a penalty of 0.5–1%. Tax-saving 5-year FDs cannot be broken early.
