Fixed Deposit Calculator

This fixed deposit calculator uses your deposit amount, annual interest rate, investment term, and compounding frequency to estimate the value of the deposit at maturity.

The selected currency determines how monetary amounts are labelled and displayed. It does not change the compound interest mathematics or automatically convert the amount between currencies.

Interest is added to the balance at the selected compounding interval. Once interest is added, later interest can be calculated on both the original deposit and previously earned interest.

The calculator also reports the total interest earned, effective annual rate, a year-by-year growth schedule, and a comparison of common compounding frequencies.

In this formula, A is the estimated maturity amount and P is the original deposit amount.

The symbol r is the annual interest rate written as a decimal, n is the number of compounding periods per year, and t is the fixed deposit term in years.

Total interest is calculated by subtracting the original deposit from the maturity amount.

A fixed deposit calculator estimates how much a lump-sum deposit could be worth at maturity based on the deposit amount, annual interest rate, investment term, and compounding frequency.

It provides a quick way to calculate the estimated maturity amount, total FD interest, effective annual rate, and the effect of compounding without manually solving the compound interest formula.

The currency selector lets you label the calculation using the currency of the fixed deposit, including currencies such as USD, EUR, GBP, MUR, INR, AUD, CAD, JPY, and others supplied by the currency data service.

Based on the values currently entered above, a deposit of $10,000.00 at an annual interest rate of 5.50% for 3 years with monthly compounding gives an estimated maturity amount of $11,789.49.

In this example, the estimated total interest earned is $1,789.49, while the effective annual interest rate is 5.64%.

More frequent compounding can produce a slightly higher maturity value because interest is credited to the balance more often.

The difference may be small over a short term, but it can become more noticeable when the deposit amount, interest rate, or term increases.

A fixed deposit may suit someone who already has a lump sum and wants predictable growth over a chosen term. A savings account normally offers easier access, while a recurring deposit can support regular monthly savings.

Product names, interest rules, access conditions, currencies, and deposit protection can vary by country and financial institution.

A fixed deposit calculator is helpful when comparing bank deposit products, choosing between different terms, or estimating how much a deposit could be worth at maturity.

You can use it to compare interest rates and compounding frequencies or to test how changing the term affects the estimated interest earned.

It can also support planning for tuition, travel, emergency reserves, future purchases, or cash that you want to keep in a relatively predictable savings product.

This calculator provides an estimate based on compound interest. An actual fixed deposit product may calculate or pay interest differently. Some banks pay interest periodically instead of adding it to the deposit balance, while others use different day-count rules or compounding schedules.

Selecting a currency changes the currency label and number format only. It does not retrieve a live exchange rate or convert the fixed deposit amount from one currency to another.

The result does not automatically account for income tax, withholding tax, inflation, account fees, early-withdrawal penalties, minimum deposit rules, promotional rates, or changes applied by a financial institution.

Before opening a fixed deposit, review the institution’s stated annual rate, effective rate, maturity instructions, renewal policy, early-withdrawal conditions, deposit protection, and applicable taxes.
