Compound Interest Formula
A = P·(1 + r/n)^(n·t)
P=Principal, r=Rate, n=Freq/yr, t=Years
Compounding Tip
Quarterly compounding on a ₹5L FD at 6.5% for 5 years earns ~₹600 more than yearly due to interest-on-interest effect.
TDS on FD
Banks deduct TDS at 10% if annual FD interest exceeds ₹40,000 (₹50,000 for senior citizens). Without PAN, TDS is 20%.
Frequently Asked Questions
How is FD maturity amount calculated?
For Compound Interest: A = P × (1 + r/n)^(n×t), where P is principal, r is annual rate (decimal), n is compounding frequency per year, and t is tenure in years. For Simple Interest: A = P + (P × r × t / 100). Compound interest always yields more for the same rate and tenure.
Which compounding frequency gives the best returns?
Monthly compounding gives the highest returns, followed by quarterly, half-yearly, and yearly. The difference is small but meaningful over long tenures. Most Indian banks compound FD interest quarterly by default.
What is the 5-year Tax Saver FD?
A Tax Saver FD has a mandatory 5-year lock-in and qualifies for deduction under Section 80C of the Income Tax Act (up to ₹1.5 lakh). However, interest earned is still taxable as per your income slab. Premature withdrawal is not permitted.
Does this calculator account for TDS deduction?
Yes — enable the "Tax on Interest" option and select your tax slab. The calculator shows gross interest, TDS deducted per year, and your net post-tax maturity amount. The maturity hero shows the gross amount; post-tax maturity appears as a stat chip below.
