Fixed Deposit Calculator: what it calculates.
A fixed deposit places a principal with a bank or institution for a defined term and stated rate. The calculator estimates maturity under a quarterly compounding convention.
The FD calculator applies principal, annual rate, tenure and quarterly compounding to estimate interest and maturity value.
How the calculation works.
Maturity = P × (1 + r/4)^(4t)
- P is the deposit principal.
- r is the annual decimal rate.
- t is tenure in years.
- The 4 represents quarterly compounding.
Worked example. ₹5 lakh at 7% for 5 years with quarterly compounding produces an illustrative maturity value near ₹7.07 lakh before tax.
What it helps with
- Estimates maturity and interest.
- Supports rate and tenure comparison.
- Uses a disclosed compounding convention.
What it does not include
- Actual bank conventions may differ.
- TDS and income tax are excluded.
- Premature closure penalties are not included.
Common questions.
What is a Fixed Deposit Calculator?
It is an educational tool that applies the disclosed fixed deposit method to the assumptions you enter.
Are the results guaranteed?
No. Results are estimates, not forecasts, approvals, quotations or guarantees.
Why should I change the assumptions?
Testing conservative and optimistic inputs exposes uncertainty instead of hiding it behind one number.
Does it include tax and fees?
Only when a tax or fee is shown as an explicit input or result. Otherwise it is excluded.
How accurate is the calculator?
The mathematics follows the stated methodology, while real outcomes depend on rates, timing, rules, fees and circumstances.
Can I use this result as financial advice?
No. Use it for education and scenario comparison, then verify decisions with official documents or a qualified professional.
Why is inflation shown?
Inflation translates a future amount into approximate present-day purchasing power. The default 6% is editable and is not a forecast.
How often should I recalculate?
Recalculate when rates, income, contributions, rules, goals or repayment terms change.
Can the result differ from a bank or platform?
Yes. Institutions may use different compounding dates, rounding, charges and eligibility rules.
Is my data uploaded?
No. Calculations run locally in your browser and the input values are not sent to a calculation server.
