Calculation methodology
The FD estimate uses compound interest with the frequency selected by the user. The formula is principal × (1 + annual rate / compounding frequency)^(frequency × years).
Formula / calculation model
FV = P × (1 + r/m)^(m×t), where m is the assumed compounding frequency.
Important assumptions and limitations
Banks may use product-specific compounding, payout and rounding conventions. Tax on interest and premature-closure penalties are not included.
