FD Basics, Choices & Pro Tips

  • Cumulative FD: Interest is reinvested; highest maturity value. Best for long-term goals.
  • Non-cumulative: Get monthly/quarterly/half-yearly/annual interest as income. Maturity value ≈ principal.
  • Senior Citizen: Many banks add 0.25%–0.75% p.a. We’ve modelled it as an “extra rate”.
  • TDS: Banks deduct TDS on interest above the annual threshold. We show a conservative estimate.
  • Inflation: Check the “real value” metric to judge purchasing power at maturity.

How to Use This Tool

FD Calculator – FAQs

How do you compute maturity for cumulative FDs?
We compound monthly/quarterly/half-yearly/annually as selected: A = P(1 + r/m)^(m·t), where r is annual rate and m is compounding periods per year.
How are non-cumulative payouts handled?
Interest is paid out at the chosen frequency; principal typically stays constant until maturity. We show total payouts plus maturity principal.
What does “Senior Citizen extra rate” do?
It adds extra percentage points to your base rate (e.g., 7.25% + 0.50% = 7.75%).
Do banks really compound monthly?
Policies vary by bank. Many compound quarterly; some credit interest monthly for non-cumulative FDs. Always match your bank’s terms.
How is TDS estimated?
We aggregate interest earned per financial year, apply the threshold, then apply your TDS rate. Actual deduction depends on your PAN/Form 15G/H and bank policy.
Is the inflation number realistic?
It’s a user input. We discount maturity by inflation to show “real” purchasing power: Real = Nominal / (1+π)^years.
What about tax slab?
We show TDS only. Your slab may require additional tax or refund on filing. Consult your advisor for slab-wise planning.
How do top-ups work?
We simulate depositing a fixed amount monthly; you can also step it up annually by a % (e.g., +10% per year).
Can I compare banks?
Yes—change rate/compounding to your bank’s offer and re-run. You can run multiple scenarios.
What is the premature penalty?
We reduce the applicable rate by entered basis points (1% = 100 bps) up to the exit month to estimate early-closure proceeds.
Do corporate FDs work the same?
Mechanics are similar, but credit risk & payout rules vary. Always verify the issuer rating and terms.
Are FD rates fixed?
Once opened, your FD rate is typically fixed for the chosen tenure (floating/callable products excluded).
What is compounding vs payout frequency?
Compounding defines how often interest is added to the principal. Payout is how often you receive interest. Cumulative: payout at maturity only.
Can minors open FDs?
Usually yes with a guardian. Rates and TDS rules still apply.
Is this calculator an offer?
No—it’s an educational illustration. Bank documentation prevails.
