Use this FD calculator (also called an FDR calculator in Bangladesh) to see how much a fixed deposit will be worth at maturity. Choose how often interest is compounded and, if you like, the tax deducted at source, to see your net return.
FD formula
Compound interest: A = P × (1 + r/n)n×t. Simple interest: A = P × (1 + r × t).
P is the deposit, r is the annual rate as a decimal, n is how many times a year interest is added and t is the term in years.
Example
A deposit of 1,00,000 at 9% for one year with quarterly compounding grows to about 1,09,308 (interest 9,308). With simple interest the same deposit grows to 1,09,000.
About tax on interest
Banks in Bangladesh deduct source tax on FDR interest, and in India TDS applies above certain limits. Rates depend on your tax status (for example whether you have a TIN or PAN) and change over time, so we do not assume a fixed rate — ask your bank for the current rate and enter it above. In Bangladesh an excise duty may also be charged on larger balances; that is not included here.
Frequently asked questions
Why is my bank’s figure slightly different?
Banks may count interest on a 360- or 365-day basis, round differently or charge fees. Confirm the final amount with your bank.
What if I withdraw the interest every month?
Interest you take out is not compounded. Choose “Simple interest” for that case.
