FD Calculator — Fixed Deposit Maturity, Gross vs Net Yield
Model a lump-sum fixed deposit using the standard compound-interest formula with selectable compounding frequency (annual through monthly). Tenure can mix years and months; optional tax trims interest only (a simplified view). Effective return annualises the growth factor so you can compare offers without mistaking nominal APR for annualised results.

What this FD math represents
A fixed deposit locks in principal for a term while interest accrues at a quoted nominal rate, compounded a finite number of times per year. Maturity equals principal times (1 + r/n)^(n·t). Payout options (monthly interest vs cumulative) change cash flow timing; this tool defaults to cumulative compounding to term unless you read the payout notes.
Why it matters
- Comparing two FDs requires aligning compounding frequency—same nominal rate with monthly compounding beats annual compounding.
- Tax on interest lowers the net cash you receive; the calculator surfaces both gross and net annualised returns.
FD levers
- Gross yield uses P × (1 + r/n)^(n·t); effective return annualises that factor.
- Tax % applies to interest only in this simplified scenario—not to principal.
- Chart compares principal vs gross interest so you see composition at a glance.
Reference (definitions)
- Nominal APR is the quoted yearly rate before compounding nuances.
- Effective annual return here annualises the actual growth factor over your full tenure.
Example conversions
| Input | Approx. output |
|---|---|
| ₹100,000 · 7% · 3y · quarterly · 0% tax | Maturity ≈ ₹123,144 (illustrative) |
Input rules
- Principal must be positive; combined tenure must be positive.
- Compounding frequency must be one of 1, 2, 4, or 12.
How to use FD Calculator
- 1 Enter principal and annual nominal rate (%).
- 2 Split tenure across whole years plus residual months if needed.
- 3 Pick compounding frequency and optional tax on interest.
- 4 Select a payout label for context (cumulative vs payout modes are explained in-output).
- 5 Review maturity, gross vs net lines, effective yields, and the narrative summary.
Formula
-
Maturity = P × (1 + r/n)^(n×t), with r decimal, n periods/year, t in years. -
Gross interest = maturity − P. -
Net maturity (simple interest tax) = P + gross interest × (1 − tax%).
