How FD Interest Is Calculated
For a simplified cumulative FD estimate, compound interest can be represented as:
Maturity Amount = P × (1 + r/n)n×t
- P = principal deposit
- r = annual interest rate in decimal form
- n = number of compounding periods per year
- t = tenure in years
Actual bank FD calculations may differ from this simplified mathematical model. Always use the bank’s stated rate, compounding method and maturity illustration for the final investment decision.
Cumulative FD vs Monthly or Quarterly Payout
Cumulative FD: interest is generally accumulated/reinvested according to the product terms, so the maturity amount can benefit from compounding.
Monthly or quarterly payout FD: interest is paid out periodically instead of being added to the deposit for compounding. This can be useful when regular cash flow is the priority.
The exact payout calculation depends on the bank and deposit scheme. Use the calculator as a planning estimate and verify the final payout with the institution.
FD Tax and TDS: What to Check
Interest from fixed deposits can be taxable. The amount of tax and whether tax is deducted at source depend on applicable tax rules, the depositor’s circumstances and the relevant financial year.
This calculator’s tax field is only an optional estimated tax-rate model. It does not determine your actual tax liability or TDS obligation.
For current tax thresholds, TDS rules and filing requirements, check the latest information published by the Income Tax Department or consult a qualified tax professional.
FD Investment Factors to Compare
- Interest rate: compare the rate for the exact tenure rather than comparing headline rates alone.
- Compounding and payout: cumulative and payout products can produce different cash-flow outcomes.
- Tenure: match the maturity date with your financial goal and liquidity needs.
- Premature closure: check applicable penalties and rate adjustments before opening an FD.
- Senior-citizen rate: confirm the eligibility age and additional rate offered by the institution.
- Tax: compare gross and estimated post-tax returns where relevant.
- Institution and product: verify the safety, terms, insurance eligibility and regulatory status applicable to the deposit you are considering.

Frequently Asked Questions About FD Calculators
What is an FD calculator?
An FD calculator estimates the maturity amount and interest earned on a fixed deposit using the deposit amount, interest rate, tenure and selected compounding or payout assumptions.
How is FD maturity calculated?
A cumulative FD can be estimated using a compound-interest model. The actual maturity amount should be checked against the bank’s official deposit illustration because product-specific calculation rules can differ.
What is the difference between cumulative and monthly payout FD?
In a cumulative FD, interest is accumulated/reinvested according to the scheme. In a monthly payout FD, interest is paid periodically instead of being added to the deposit balance.
Can I calculate FD interest for a senior citizen?
Yes. Select Senior Citizen in Advanced FD Options and enter the additional rate offered by the bank or scheme. Senior-citizen rates vary by institution and tenure.
Does FD interest compound monthly?
It depends on the FD product. Select the compounding frequency stated in the applicable deposit terms. Do not assume monthly compounding for every FD.
Is FD interest taxable?
FD interest can be taxable. The applicable tax and TDS treatment depends on current rules and the depositor’s circumstances. Use the tax option here only for an estimate.
Can this FD calculator calculate monthly interest?
Yes. Select Monthly Payout to see an estimated monthly interest payout. The exact payout should be confirmed with the bank because payout products can use scheme-specific calculations.
Is this FD calculator suitable for all banks?
It is a general planning calculator. Banks and financial institutions can use different rates, compounding methods, day-count conventions, payout rules and product conditions, so verify the final maturity value with the institution.
Can I use this calculator for different interest rates?
Yes. Change the interest rate and use the rate-comparison section to see how the estimated outcome changes.
