Overview

The ToolsForges Fixed Deposit calculator computes the maturity value and total interest earned on fixed-deposit investments across various compounding frequencies — quarterly, half-yearly, and annually. Input the principal deposit amount, annual interest rate, tenure, and compounding interval to receive an instantaneous maturity projection. The tool supports both cumulative and non-cumulative FD modes, where interest is either reinvested at maturity or paid out periodically.

Feature Specifications

• Multiple Compounding FrequenciesChoose between annual, half-yearly, and quarterly compounding to match the terms offered by different banks and financial institutions for accurate maturity comparisons.
• Cumulative and Non-Cumulative ModesCompute maturity value for cumulative FDs where interest is reinvested, or calculate periodic interest payouts for non-cumulative FDs used for regular income needs.
• TDS EstimationView estimated tax deducted at source on interest income based on current TDS thresholds, helping depositors plan post-tax returns accurately.
• Bank Comparison SupportRun parallel calculations with different interest rates from multiple banks to identify the most favorable deposit option for your investment horizon.

Architecture

The calculator uses React useState for input management and the compound interest formula A = P(1 + r/n)^(nt) for maturity computation. TDS estimation applies the current threshold before calculating net returns.
