About this tool

A fast, accurate Fixed Deposit calculator using the standard compound interest formula — A = P × (1 + r/n)^(n×t) — the same formula used by all Indian banks. Enter your deposit amount, annual interest rate, and duration; the maturity value and interest earned update instantly as you type or drag the sliders.

Switch between yearly, quarterly, and monthly compounding to compare the impact of compounding frequency on your returns. The donut chart and progress bars visualise how much of the maturity amount is your original deposit versus the interest it earned. Quick preset chips let you jump to common amounts and rates without typing. All calculations run entirely in your browser — no data is sent to any server.

Frequently asked questions

Common questions about Fixed Deposit interest calculation, compounding, and tax in India.

Maturity Amount = P × (1 + r/n)^(n×t), where P is the principal, r is the annual interest rate as a decimal, n is the number of compounding periods per year (1 for yearly, 4 for quarterly, 12 for monthly), and t is the time in years. This is the standard compound interest formula used by all Indian banks.

Compounding frequency determines how often interest is calculated and added to your principal. Monthly compounding earns slightly more than quarterly, which earns more than yearly, because interest starts earning interest sooner. For example, ₹1L at 7% for 3 years: yearly gives ₹1,22,504; quarterly gives ₹1,23,144; monthly gives ₹1,23,330.

Small finance banks (e.g., Unity SFB, Jana SFB, Suryoday SFB) typically offer 8–9.5% for regular depositors and up to 9.5–10% for senior citizens. Major nationalised banks (SBI, PNB, Bank of Baroda) offer 6.5–7.5%. Private sector banks (HDFC, ICICI, Axis) offer 7–7.5%. Rates change frequently — always verify on the bank's official site before investing.

Yes. Most Indian banks offer an additional 0.25%–0.5% p.a. over the regular rate for depositors aged 60 and above. Some banks offer a further additional 0.25%–0.5% for super-senior citizens (aged 80+). Enter the applicable senior citizen rate in the interest rate field to see the correct maturity amount.

Yes. FD interest is added to your total income and taxed at your applicable slab rate. Banks deduct TDS at 10% when interest exceeds ₹40,000 per year (₹50,000 for senior citizens). If your total income is below the taxable limit, submit Form 15G (general) or 15H (senior citizens) to the bank to avoid TDS deduction.

Premature withdrawal is allowed at most banks but attracts a penalty of 0.5%–1% reduction in the applicable interest rate. The actual interest earned will be recalculated at the lower rate for the actual holding period. Some banks waive premature withdrawal penalties for FDs held for more than a certain duration.

For FDs of less than 6 months or 180 days, most banks apply simple interest, not compound interest. This calculator uses compound interest, which is appropriate for standard FD tenures of 6 months and above. For very short-tenure FDs, the actual interest may be marginally lower than shown.
