Cumulative: Maturity = P × (1 + r ÷ m)m × t (m = 4 for quarterly) · Payout: interest per payout = P × r ÷ payouts a year
Details
How this works
In a cumulative FD the interest is added each quarter and earns interest itself. In a payout FD it is paid to you and the principal stays the same.
Compare FDs by their effective annual yield, not the quoted rate.
Frequently asked questions
Is FD interest taxable?
Yes, at your slab rate, each year as it accrues. Banks deduct TDS above a threshold.
What about senior-citizen rates?
