About Fixed Deposit (FD) & Recurring Deposit (RD) Maturity Calculator
Calculate terminal maturity values, quarterly compound interest yields, senior citizen rate bonuses, and Tax Deducted at Source (TDS) thresholds.
Fixed Deposits (FD) and Recurring Deposits (RD) are foundational, low-volatility fixed-income instruments offered by scheduled commercial banks, regional rural banks, post offices, and NBFCs. An FD requires a one-time lump-sum deposit for a fixed tenure ranging from 7 days up to 10 years, whereas an RD permits individuals to deposit a predetermined monthly installment from their operational cash flow.
Per Reserve Bank of India (RBI) regulations, domestic term deposits with maturities exceeding 180 days compound interest on a quarterly basis (every three months: March, June, September, and December). Because earned interest is added to the principal balance at the end of each quarter, the depositor earns interest on accumulated interest over subsequent quarters. This quarterly compounding engine produces an Effective Annual Yield (APY) that exceeds the nominal interest rate printed on the bank fixed deposit receipt.
Taxation is an essential factor in fixed deposit planning. Interest income from bank deposits is fully taxable under "Income from Other Sources" at the investor's marginal income tax slab. Under Section 194A of the Income Tax Act, banks deduct 10% TDS if aggregate annual interest across all branches of a bank exceeds ₹40,000 for regular depositors or ₹50,000 for senior citizens (aged 60 and above).
Step-by-Step Usage Guide
Choose Deposit Type (FD vs RD)
Select Fixed Deposit if you have an existing lump-sum corpus to invest, or Recurring Deposit if you want to save a fixed amount each month.
Enter Deposit Amount
Specify your one-time principal for FD or your regular monthly installment for RD.
Input Annual Interest Rate (%)
Enter the annualized interest rate offered by your bank for your chosen tenure. Remember that senior citizens typically receive an additional 0.50% interest bonus.
Select Investment Horizon
Choose your tenure from 1 to 10 years. Longer tenures benefit from prolonged quarterly compounding cycles.
Review Maturity Value & Effective Returns
Examine the total maturity payout, pure interest earnings, and comparison between invested principal and accumulated returns.
Case Study: ₹2,00,000 Cumulative Fixed Deposit at 7.25% p.a. for 5 Years (Quarterly Compounding)
A depositor opens a 5-year cumulative term deposit with ₹2,00,000 at a commercial bank offering a nominal annual rate of 7.25% compounded quarterly.
- ›Quarterly Periodic Rate i = 7.25% ÷ 4 ÷ 100 = 0.018125
- ›Total Compounding Periods N = 4 × 5 = 20 Quarters
- ›Compounding Multiplier (1 + i)^20 = (1.018125)^20 ≈ 1.431604
- ›Terminal Maturity Amount A = ₹2,00,000 × 1.431604 = ₹2,86,321
- ›Total Compound Interest Earned = ₹2,86,321 - ₹2,00,000 = ₹86,321
- ›Simple Interest Comparison: ₹2,00,000 × 7.25% × 5 = ₹72,500
- ›Compounding Advantage: Quarterly compounding generates an extra ₹13,821 in returns!
- ›Effective Annualized Yield (APY) = (1 + 0.018125)^4 - 1 = 7.45% per annum
Under cumulative mode, interest is reinvested quarterly, maximizing final payout. If non-cumulative monthly/quarterly payout is chosen instead, interest is credited directly to your savings account.
Formula & Mathematical Specification
Fixed Deposit Quarterly Compounding Formula
Standard formula mandated by the Reserve Bank of India for domestic term deposits compounded quarterly.
- A:Final maturity payout amount at end of tenure
- P:Initial lump-sum principal deposited
- r:Nominal annual interest rate (e.g. 7.25% = 0.0725)
- 4:Compounding frequency per calendar year (quarterly)
- t:Tenure of deposit in completed years
Recurring Deposit Maturity Formula
Sum of individual compound growths for each monthly installment over its remaining months until maturity.
- P:Fixed monthly installment deposit
- n:Total number of months in deposit tenure
Effective Annual Yield (APY)
The real annual return earned on the deposit when taking quarterly reinvestment into account.
Best Practices & Pro Tips
- ✓Adopt an FD Laddering Strategy: Instead of locking ₹5 Lakhs into a single 5-year deposit, divide it into five ₹1 Lakh deposits with 1, 2, 3, 4, and 5-year maturities to maintain annual liquidity.
- ✓Submit Form 15G or 15H to avoid TDS: If your total taxable income is below the basic tax exemption limit, submit Form 15G (for under 60) or Form 15H (for senior citizens) at the beginning of each financial year.
- ✓Claim Senior Citizen Benefits: Individuals aged 60 and above receive a standard 0.50% interest rate premium across most Indian public and private sector banks.
- ✓Check DICGC Sovereign Insurance: Bank deposits (including principal and interest) are insured up to ₹5,00,000 per depositor per bank by the Deposit Insurance and Credit Guarantee Corporation (a wholly-owned subsidiary of RBI).
Common Mistakes to Avoid
- ✗Breaking FDs Prematurely: Withdrawing a fixed deposit before maturity typically incurs a 0.5%–1.0% interest rate penalty, lowering the yield retroactively for the elapsed duration.
- ✗Ignoring Income Tax Liability on Accrued Interest: Even if you choose cumulative payout and do not withdraw interest annually, accrued interest must be declared in your annual income tax return.
- ✗Assuming 10% TDS Means Full Tax Paid: If you fall in the 20% or 30% tax slab, the bank only deducts 10% TDS; you must pay the remaining differential self-assessment tax.
- ✗Relying Exclusively on Bank FDs for 15+ Year Horizons: Over decades, fixed deposit returns after factoring in income tax and inflation often result in flat or negative real purchasing power.

Frequently Asked Questions
How does quarterly compounding in bank Fixed Deposits work?▼
Banks calculate interest every three months (March, June, September, December). At the end of each quarter, accrued interest is added to your starting principal, meaning subsequent quarters earn interest on both your initial deposit and the newly credited interest.
What is the difference between Cumulative and Non-Cumulative FDs?▼
In a Cumulative (Reinvestment) FD, interest compounds quarterly and is paid out in one lump sum at maturity. In a Non-Cumulative FD, interest is disbursed directly to your savings account on a monthly, quarterly, or annual basis to provide regular cash flow.
What is the TDS threshold on bank fixed deposit interest?▼
Under Section 194A, banks deduct 10% TDS if total interest across all branches of that bank exceeds ₹40,000 in a financial year for general citizens, or ₹50,000 for senior citizens (aged 60+). If PAN is not provided, TDS is deducted at 20%.
How is Recurring Deposit (RD) interest calculated differently from FD?▼
In an FD, the entire lump sum compounds from day one. In an RD, you deposit money every month. Your first installment earns interest for the full tenure, your second installment earns interest for one month less, and your final installment earns interest for just one month.
Are bank fixed deposits safe from bank default?▼
Yes. Up to ₹5,00,000 per depositor per bank (including both principal and accrued interest) is legally guaranteed and insured by the Deposit Insurance and Credit Guarantee Corporation (DICGC), a statutory subsidiary of the Reserve Bank of India.
Does this calculator store or send my deposit amounts to servers?▼
No. All compounding math and maturity schedules are evaluated 100% locally in your web browser memory. Zero financial inputs or personal balances are ever transmitted to or stored on remote servers.
