How the FD Calculator (Fixed Deposit Maturity) works
A fixed deposit compounds interest m times a year: maturity = P × (1 + r ÷ m)^(m × years). Indian banks usually compound FDs quarterly; US CDs often compound daily or monthly.
The effective annual yield (APY) shows the yearly return including compounding, so you can compare deposits with different compounding.
The formula
Worked example
Using the default values shown in the calculator:
| Deposit amount | $100000 |
|---|---|
| Interest rate (yearly) | 7 % |
| Tenure (years) | 3 |
| Compounding | Quarterly (common for Indian bank FDs) |
| Tax on interest | 0 % |
- 100,000 at 7% for 3 years, compounded quarterly, matures at $123,143.93.
- Interest earned is $23,143.93, an effective yield of 7.19.
Result:
| Maturity value | $123,143.93 |
|---|---|
| Interest earned | $23,143.93 |
| Effective annual yield | 7.19% |
| Interest after tax | $23,143.93 |
Frequently asked questions
Is FD interest taxable?
Usually yes, as income in the year it accrues. In India banks deduct TDS above a threshold; the tax field lets you see the after-tax interest.
