How Does TMB Bank's FD Calculator Work?

- Tenure: Duration of deposit in years.
- Maturity Value: Final payout amount at the end of your FD term.
- Interest Earned: Maturity amount minus principal.
The calculator uses the compound interest formula to give accurate results, since FD interest at TMB is usually compounded quarterly.
Formula To Determine TMB FD Returns
Most bank FDs, including TMB, follow the compound interest method:
Compound Interest Formula:
M = P(1 + r/n)^(n × t)
Where:
- M = Maturity Amount
- P = Principal amount
- r = Annual interest rate
- n = Compounding frequency
- t = Time period (in years)
Example Calculation
If you invest ₹10,00,000 in a TMB FD for 3 year at an interest rate of 6.60%, compounded quarterly:
Interest Earned: ₹2,11,356
Maturity amount: ₹12,11,356
This helps you estimate returns clearly before investing.
