Our FD calculator uses the compound interest formula: A = P(1 + r/n)^(nt) where A is maturity amount, P is principal, r is annual interest rate, n is compounding frequency, and t is time period. It calculates the exact maturity value and interest earned based on your deposit amount, interest rate, tenure, and compounding frequency selected.

Our FD calculator supports interest rates from 1% to 15% per annum to accommodate different bank offerings. Current market rates typically range from: Senior citizen FDs (5.5%-7.5%), Regular FDs (4.5%-7%), Corporate FDs (6%-8.5%), and Special tenure FDs (up to 8%). The calculator provides accurate calculations for any rate within the supported range.

Compounding frequency significantly impacts FD returns. Higher frequency means more frequent addition of interest to principal, resulting in higher maturity amounts. Our calculator supports: Monthly compounding (highest returns), Quarterly compounding (most common), Half-yearly compounding, and Annual compounding. The difference becomes more pronounced with larger amounts and longer tenures.

Yes, our FD calculator supports tenures from 3 months (0.25 years) to 10 years to cover all standard bank FD options. Short-term FDs (3-12 months) typically offer lower rates, while longer-term FDs (2-10 years) generally provide higher interest rates. The calculator shows how tenure affects both interest earned and maturity amount.

Our FD calculator works for most standard fixed deposits including regular FDs, senior citizen FDs, tax-saving FDs (under 80C), and corporate FDs. However, it assumes compound interest calculation. Some specialized deposits like cumulative vs. non-cumulative FDs may have different payout structures that require specific calculations.

Yes, our FD calculator is completely free with no registration required. It provides 100% accurate calculations using the standard compound interest formula used by banks. You can perform unlimited calculations for comparing different FD options and planning your deposits. Always verify rates and terms with your chosen bank before investing.

Use our FD calculator to compare different scenarios by adjusting principal amount, interest rate, tenure, and compounding frequency. This helps you choose the optimal FD option for your financial goals. Compare returns across different banks and tenures to maximize your earnings while considering liquidity needs and interest rate trends.

FD returns are most affected by: Interest rate (higher rate = higher returns), Tenure (longer period = more compounding), Principal amount (larger amount = higher absolute returns), and Compounding frequency (more frequent = slightly higher returns). Interest rate changes have the most significant impact on total returns over the investment period.
