Fixed Deposit Calculator

What your FD matures to.

Calculate fixed deposit maturity amount using principal, interest rate, term, and compounding frequency to see total balance and interest earned.

What this tool does

Fixed deposit maturity amount equals principal compounded at the annual rate over the term, with the chosen compounding frequency. The calculator models what your deposit grows to by applying compound interest at regular intervals—monthly, quarterly, annually, or another frequency you select. The maturity amount shown represents your total balance at the end of the term, while interest earned is the gain above your initial principal. The result depends most on the principal amount, annual rate, and length of term; compounding frequency has a smaller effect. This tool illustrates growth under stable conditions and is useful for comparing different deposit offers or terms. The calculation assumes the rate remains fixed and no deposits or withdrawals occur during the term.

Quick answer: with the default values, the result is $14,147.78 (Maturity Amount). Adjust the values below for your own figures.

Fixed deposits lock money for a set term in exchange for a fixed contracted rate. The maturity amount depends on principal, rate, term, and compounding frequency. Quarterly compounding is common in some markets, annual in others. This calculator handles both.

10,000 at 7% for 5 years with quarterly compounding matures to 14,148. The same at annual compounding gives 14,026 - a small but real difference. More frequent compounding always produces higher returns; over long terms the gap widens noticeably.

Fixed deposits are low-risk. The rate is fixed at origination so inflation risk is real - a 7% FD during 5% inflation has just 2% real return. The rate is often compared to long-term government bond yields (similar risk) rather than to savings account rates, which are shorter term and lower risk.

A worked example

With the defaults: principal of 10,000, annual rate of 7%, term of 5, compounding frequency of 4. The tool returns 14,147.78.

What moves the number most

The result responds to Principal, Annual Rate, Term, and Compounding Frequency.

The formula behind this

Standard compound interest formula: Maturity = Principal × (1 + rate/frequency)^(frequency × years).

Sources & Methodology

Methodology

This calculator computes the maturity value of a fixed deposit using the compound interest formula. The model takes your principal amount and applies the annual interest rate compounded at your chosen frequency—monthly, quarterly, or annually—over your deposit term. The calculation assumes a fixed interest rate that remains constant throughout the period, and that all interest is reinvested without withdrawal. The result shows the total value at maturity, combining original principal and accrued interest. The calculator does not account for taxes, inflation, fees charged by the deposit provider, or changes in interest rates. It also models growth assuming regular compounding intervals and does not reflect any early withdrawal penalties or market-related factors.

Frequently Asked Questions

Monthly or quarterly compounding?
Monthly compounding produces slightly higher returns than quarterly, though the difference is small — typically a fraction of a percent of the maturity value over a 5-year term. Daily compounding adds another small bump. Most FDs offer quarterly as standard; monthly is sometimes available on request.
Is a fixed deposit safe?
Yes for the nominal amount. FDs are typically covered by a national deposit-guarantee scheme up to a per-depositor limit that varies by country. The real risk is inflation - a 5% FD during 6% inflation loses purchasing power despite a positive return.
Break an FD for a better rate?
Rarely. Breaking usually incurs penalty (typically 0.5-1% of principal or forfeited interest). The new rate needs to be meaningfully higher (2+ percentage points) over the remaining term to justify the break.
What's the difference between FD and savings?
FDs lock money for a fixed term at a higher rate. Savings accounts offer instant access at lower rates. FDs typically pay more than equivalent instant-access savings, reflecting the fixed term. FDs are generally used for money not needed for 6+ months, with savings accounts used for shorter-term funds.
