What is a Fixed Deposit Calculator?
A fixed deposit calculator is a free online tool that computes the maturity value of a fixed deposit investment. Since FD returns depend on four variables - principal amount, interest rate, compounding frequency, and tenure - manual calculation is both time-consuming and error-prone. The calculator handles all of it instantly.
Cready's FD calculator online goes further than most basic tools by letting you toggle between:

How to Calculate Fixed Deposit Interest
There are two types of FD interest calculations in India - simple interest and compound interest. Most bank FDs use compound interest, compounded quarterly by default (though some NBFCs compound monthly, and post office FDs compound quarterly).
Simple Interest FD Formula
Used by some short-tenure FDs and post office term deposits
Simple interest calculates returns only on the principal amount, without reinvesting earned interest.
Example Calculation
₹1,00,000 at 7% p.a. for 3 years (simple interest): M = ₹1,00,000 + (1,00,000 × 7 × 3 / 100) = ₹1,21,000
Simple Interest Formula
M = Maturity amount
P = Principal (your investment)
r = Annual interest rate (%)
t = Tenure in years
Compound Interest FD Formula
Used by most bank FDs
Compound interest reinvests earned interest, so you earn interest on interest over time.
Example Calculation
₹1,00,000 at 7% p.a., compounded quarterly (n=4), for 5 years: M = 1,00,000 × (1 + 0.07/4)^(4×5) = ₹1,41,478
Impact of Compounding Frequency
The same deposit compounded monthly gives ₹1,41,763 - slightly higher, because interest compounds more frequently.
This is exactly the calculation Cready's fixed deposit interest calculator performs instantly - no formula needed on your end.
Compound Interest Formula
M = Maturity amount
P = Principal
r = Annual interest rate (as a decimal)
n = Compounding periods per year (1 = yearly, 2 = half-yearly, 4 = quarterly, 12 = monthly)
t = Tenure in years
