FD Calculator – Fixed Deposit Calculator
Free online FD calculator to estimate fixed deposit maturity value, interest earned, and annualized yield from deposit amount, interest rate, term, and compounding frequency. This calculator is useful for savers, finance students, bank customers, retirement planners, and anyone comparing fixed deposit options. A fixed deposit is designed to lock money for a set period at a stated rate, so the most common questions are how much the deposit will grow to, how much interest it will earn, and how different rates or terms change the final maturity amount. This page gives a quick and practical way to answer those questions.
This calculator uses four inputs. Fixed deposit amount means the money placed into the FD at the start. Annual interest rate means the yearly rate offered on the deposit. FD term means the total deposit period in years. Compounds per year means how often the interest is applied or credited during one year. Once those values are entered, the calculator shows FD maturity value, interest earned, annualized yield, and maturity value per $1,000 deposit. These outputs make it easier to compare fixed deposit choices by both total maturity value and effective yearly growth.
The formula of fixed deposit calculator
Maturity value = Fixed deposit amount x (1 + Annual rate / Compounds per year) ^ (Years x Compounds per year)
Interest earned = Maturity value – Fixed deposit amount
Annualized yield = (Maturity value / Fixed deposit amount) ^ (1 / Years) – 1
Maturity value per $1,000 deposit = (Maturity value / Fixed deposit amount) x 1000
Here fixed deposit amount means the initial deposited principal, annual rate means the quoted yearly interest rate, compounds per year means the number of compounding periods in one year, maturity value means the total value at the end of the FD term, interest earned means the amount gained above the original deposit, and annualized yield means the effective yearly growth implied by the FD result.
Solved Example
Example 1: Find the maturity value if the fixed deposit amount is $10,000, annual interest rate is 6%, FD term is 3 years, and interest compounds quarterly.
Solve: Maturity value = 10000 x (1 + 0.06 / 4) ^ 12 = $11,956.18
Interest earned = 11956.18 – 10000 = $1,956.18
Annualized yield = (11956.18 / 10000) ^ (1 / 3) – 1 = 6.14%
Example 2: Find the result if the deposit amount is $25,000, annual rate is 7%, term is 5 years, and compounding is annual.
Solve: Maturity value = 25000 x (1.07) ^ 5 = $35,063.79
Interest earned = 35063.79 – 25000 = $10,063.79
Annualized yield = 7.00%
Example 3: Find the result if the deposit amount is $50,000, annual rate is 5.5%, term is 2 years, and compounding is monthly.
Solve: Maturity value = 50000 x (1 + 0.055 / 12) ^ 24 = $55,799.88
Interest earned = 55799.88 – 50000 = $5,799.88
Annualized yield = (55799.88 / 50000) ^ (1 / 2) – 1 = 5.64%

How to use this FD calculator
Enter the fixed deposit amount in the proper input field. After that, enter the annual interest rate, the FD term in years, and the compounding frequency. Then click the calculate button. The calculator will show FD maturity value, interest earned, annualized yield, and maturity value per $1,000 deposit in the result box.
This calculator is useful when comparing fixed deposit products, testing different deposit terms, checking maturity proceeds before opening an account, or planning savings targets with a bank deposit. A higher rate or longer term usually increases maturity value, but compounding frequency can also change the final result. Looking at annualized yield beside maturity value helps users compare products on a more equal basis instead of focusing only on the quoted rate.
When using the result, remember that this calculator does not include taxes, premature withdrawal penalties, renewal rules, or changing rates over time. It is best used as a clean estimate tool for a fixed-rate deposit held to maturity. Even so, fixed deposit calculators remain one of the clearest ways to plan low-risk savings and compare bank deposit offers.
