FD Calculator: Calculate Fixed Deposit Interest & Maturity Amount (2025)
Want to know how much your savings will grow in a fixed deposit (FD)? The FD Calculator is a simple online tool that helps you calculate your total maturity amount, interest earned, and effective return rate. Whether you’re investing in a bank FD or a company FD, this calculator gives you quick and accurate results — so you can make better financial decisions.
What is an FD (Fixed Deposit)?
A Fixed Deposit (FD) is a secure investment option offered by banks and financial institutions. You deposit a lump sum of money for a fixed tenure at a predetermined interest rate. At the end of the period, you receive your principal amount plus accumulated interest.
FDs are considered one of the safest investment options because they offer guaranteed returns and are not affected by market fluctuations.
What is an FD Calculator?
An FD Calculator helps you estimate the maturity value and total interest earned on your fixed deposit. You just need to enter:
- Deposit amount
- Interest rate (annual)
- Tenure (in months or years)
- Type of compounding (monthly, quarterly, half-yearly, or yearly)
The calculator then instantly shows your total maturity amount and interest earned — without manual calculations.
Why Use an FD Calculator?
Using an FD calculator saves time and helps you make smarter financial decisions. Here’s why it’s useful:

FD Calculator Formula
The maturity amount of a fixed deposit depends on the type of compounding applied — simple or compound interest.
For Simple Interest FD:
Maturity Amount = Principal + (Principal × Rate × Time) / 100For Compound Interest FD:
Maturity Amount = P × (1 + r/n)^(n × t)- P = Principal amount
- r = Annual interest rate (in decimal)
- n = Number of compounding periods per year
- t = Time in years
Interest Earned:
Interest = Maturity Amount – PrincipalExample of FD Calculation
Example 1 (Quarterly Compounding):
- Deposit Amount = ₹1,00,000
- Interest Rate = 7% p.a.
- Tenure = 5 years
- Compounding = Quarterly
Calculation:
Maturity Amount = 1,00,000 × (1 + 0.07/4)^(4×5) = ₹1,40,255
Total Interest Earned = ₹40,255
So, after 5 years, you’ll receive ₹1,40,255 in total.
Types of Fixed Deposits
1. Cumulative FD
In a cumulative FD, interest is compounded periodically and paid at maturity. It’s ideal for long-term investors.
2. Non-Cumulative FD
In this type, interest is paid out monthly, quarterly, or annually. It’s suitable for those seeking regular income, like retirees.
3. Tax-Saving FD
These FDs come with a lock-in period of 5 years and offer tax benefits under Section 80C of the Income Tax Act.
4. Senior Citizen FD
Senior citizens usually enjoy 0.25% to 0.50% higher interest rates compared to standard FDs.
How Does the FD Calculator Work?
The FD calculator works by applying the compound interest formula based on your inputs. Here’s how:
- Enter your deposit amount (e.g., ₹1,00,000).
- Enter the interest rate (e.g., 7%).
- Enter the tenure (e.g., 5 years).
- Select the compounding frequency (monthly, quarterly, yearly).
- Click “Calculate”.
- The calculator displays your maturity value and interest earned.
Factors That Affect FD Returns
- 1. Interest Rate: Higher rates = more returns.
- 2. Compounding Frequency: Quarterly compounding earns more than annual compounding.
- 3. Tenure: Longer tenures usually offer better interest rates.
- 4. Type of FD: Cumulative FDs earn higher returns than non-cumulative ones.
- 5. Investor Type: Senior citizens enjoy higher rates.

Taxation on Fixed Deposits
- Interest earned on FDs is taxable under “Income from Other Sources.”
- Banks deduct TDS (Tax Deducted at Source) at 10% if annual interest exceeds ₹40,000 (₹50,000 for senior citizens).
- You can submit Form 15G/15H to avoid TDS if your income is below the taxable limit.
FD Calculator for Monthly Interest
Some investors prefer regular income from FDs. In such cases, a Non-Cumulative FD Calculator helps calculate monthly, quarterly, or annual interest payouts.
Example:
- Deposit = ₹5,00,000
- Interest Rate = 7% p.a.
- Tenure = 5 years
Monthly Interest = (5,00,000 × 7%) ÷ 12 = ₹2,916/month
