How Fixed Deposit Returns Are Calculated
Simple Interest (No Compounding):
| Calculation | Formula |
|---|---|
| Monthly Interest | (Principal × Annual Rate) ÷ 12 |
| Total Interest | Monthly Interest × Tenure (months) |
| Maturity Value | Principal + Total Interest |
Compound Interest:
| Calculation | Formula |
|---|---|
| Maturity Value | Principal × (1 + Rate ÷ n)^(n × t) |
| Total Interest | Maturity Value − Principal |
| Monthly Interest | Total Interest ÷ Tenure (months) |
Where: - n = Number of compounding periods per year - t = Time in years
