FD Calculator
Estimate fixed deposit maturity value with quarterly, monthly, or yearly compounding.
One-time lump sum deposited in the FD.
Annual interest rate offered by the bank.
Length of the deposit.
How often interest is reinvested into the deposit.
Uses cumulative (reinvestment) FD math: A = P × (1 + r/n)^(n×t). Estimates only — bank payout schedules, TDS, and premature withdrawal penalties are not modeled. Returns are not guaranteed.
How is FD maturity calculated?
Interest compounds at the chosen frequency on the principal. Maturity = principal plus all compounded interest over the tenure. Zero-rate FDs return the principal unchanged.
Does this match my bank statement exactly?
Banks may use slightly different compounding conventions, payout vs cumulative products, or round at each period. Use this as a planning estimate and confirm with your bank.
What compounding frequency should I pick?
Choose the frequency stated in your FD terms — most Indian bank cumulative FDs compound quarterly. More frequent compounding yields a slightly higher maturity for the same nominal rate.
Is TDS included?
No. Interest above ₹40,000/year (₹50,000 for senior citizens) may attract TDS at 10% unless Form 15G/15H is submitted. This calculator shows gross maturity before tax.
Can I use this for tax-saving FDs?
The formula is the same, but tax-saving FDs have a 5-year lock-in and separate deduction rules under Section 80C. Lock-in and tax benefits are not modeled here.
