How FD interest is worked out

Most Indian banks add interest to a fixed deposit every quarter, so the interest itself earns interest:

Maturity = P × (1 + r ÷ n)n × t

P is the deposit, r the yearly rate (as a decimal), n the number of times interest is added each year, and t the years. If you take the interest out every month or quarter, there is no compounding: interest = P × r × t.

Things to check

  • Senior citizens usually get about 0.5% more. Enter the rate your bank offers you.
  • FD interest is taxed at your slab rate. Banks deduct TDS when interest passes a yearly limit; this calculator shows interest before tax.
  • Deposits up to ₹5 lakh per bank per person are insured by DICGC.

Questions

Is a 5-year tax-saving FD covered?

Yes, the maths is the same. The deduction under section 80C is allowed only in the old regime.

Why does my bank show a slightly different figure?

Banks count days exactly and some round at each quarter. The difference is usually a few rupees.
