FD Calculator – Calculate Fixed Deposit Maturity & Interest
The PlanMyReturns FD Calculator helps you calculate the maturity value, interest earned, and payout income from a fixed deposit based on bank interest rates, tenure, payout option, and senior citizen benefits.
This calculator is built for people who want clarity before booking an FD, not rough estimates.
What Is a Fixed Deposit (FD)?
A Fixed Deposit (FD) is a low-risk investment where you deposit a lump sum with a bank or post office for a fixed period at a predetermined interest rate.
At the end of the tenure, you receive:
- The original principal, and
- The interest earned (either periodically or at maturity)
FDs are widely used for capital protection, predictable returns, and income generation.
Why People Use an FD Calculator
Most users search for an FD calculator to answer questions like:
- How much will my FD grow in 3 or 5 years?
- What interest will I earn on ₹1 lakh FD?
- Should I choose monthly payout or cumulative FD?
- How much extra do senior citizens earn?
- What is the real value of FD returns after inflation?
This calculator answers all of these clearly.

FD Payout Options Explained
Your FD returns depend heavily on the payout frequency you choose.
Compounded FD (Cumulative FD)
- Interest is reinvested
- Highest maturity value
- Paid fully at the end of tenure
Best for long-term wealth accumulation.
Monthly Interest Payout FD
- Fixed monthly income
- Principal returned at maturity
Often used by retirees for regular cash flow.
Quarterly Interest Payout FD
- Interest paid every 3 months
- Slightly higher yield than monthly payout
Annual Interest Payout FD
- Interest paid once a year
- Suitable for yearly income needs
Simple Interest FD (At Maturity)
- Interest calculated on principal only
- Lower returns compared to compounding
- Entire amount paid at maturity
Tenure Selection: Years or Months
This calculator allows tenure selection in:
- Years (for long-term FDs)
- Months (for short-term deposits)
The calculation automatically adjusts compounding or payout periods based on tenure unit.
Senior Citizen FD Benefit
Banks usually offer higher FD rates to senior citizens.
In this calculator:
- Selecting Senior Citizen: Yes automatically adds extra interest
- Bank quick-rate cards also reflect senior rates
This helps you compare normal vs senior citizen FD returns instantly.
Popular Bank FD Rates (Quick Select)
The calculator includes popular bank rate presets such as:
- SBI
- HDFC Bank
- ICICI Bank
- Post Office
Selecting a bank auto-fills the applicable interest rate so you can compare maturity values faster.
Inflation Adjustment (Advanced Feature)
FD returns often look attractive, but inflation reduces real value.
This calculator includes an optional inflation adjustment:
- Enter expected inflation rate
- View inflation-adjusted maturity value
- Understand real purchasing power of FD returns
This feature is rarely available in basic FD calculators.
FD Interest Calculation Formula
Compound FD Formula
A = P × (1 + r/n)ⁿᵗ
Where:
- A = maturity amount
- P = principal invested
- r = annual interest rate
- n = compounding frequency
- t = tenure in years
Simple Interest Formula
Interest = P × r × t
FD Example
Suppose you invest ₹1,00,000 in an FD for 5 years at 7% interest.
Cumulative FD
- Maturity value: ~₹1.40 lakh
- Total interest earned: ~₹40,000
Monthly Payout FD
- Monthly income: ~₹580
- Principal returned at maturity: ₹1,00,000
Inflation-Adjusted Value (6%)
- Real value: ~₹1.05 lakh
The calculator shows exact values and breakdowns.
