How it works & FAQs

The math behind the numbers, plus answers to the questions we hear most often.

How is FD interest calculated?
Indian banks use compound interest, typically compounded quarterly. The formula is M = P × (1 + r/n)^(n×t). Monthly-payout FDs use simple interest. Toggle above to compare both.
When is TDS deducted on FD interest?
Banks deduct 10% TDS once annual interest crosses ₹40,000 (₹50,000 for senior citizens). To avoid TDS if your total income is below the taxable limit, submit Form 15G/15H at the start of the financial year.
What is the senior citizen bonus?
Most banks offer 0.25–0.75% extra interest on FDs for citizens aged 60 and above. We apply a flat +0.50% above the standard rate as a typical benchmark.
Are small-finance bank FDs safe?
SFB deposits up to ₹5 lakh are insured by DICGC, the same as any scheduled commercial bank. They typically offer 0.5–1.5% higher rates — often the best post-tax return for conservative savers.
