Frequently Asked Questions
How is FD maturity calculated?
Maturity = Principal × (1 + r/n)^(n×t), where r is the yearly rate, n the compounding frequency and t the years.
How is RD calculated?
Each monthly deposit earns quarterly-compounded interest for the months it stays in the account, and all deposits are added up.
Why does my bank show a slightly different amount?
Banks may use different rounding, day counts or compounding. This is an estimate before tax/TDS.
