CISCE: Class 10
Definition: Recurring Deposit Account (R.D. Account)
A scheme in which a fixed amount is deposited every month for a fixed period.
CISCE: Class 10
Definition: Maturity Period
Total time (in months/years) for which deposits are made.
CISCE: Class 10
Definition: Maturity Value (M.V.)
Total amount received at the end = Total deposits + Interest.
CISCE: Class 10
Formula: Interest on R.D.
\[I=P\times\frac{n(n+1)}{2\times12}\times\frac{r}{100}\]
Months = Years × 12
-
P = Monthly instalment
-
n = Number of months
-
r = Rate of interest (% p.a.)
-
I = Interest
-
M.V. = Maturity Value
CISCE: Class 10
Formula: Total Amount Deposited
Total Deposit = P × n
CISCE: Class 10
Formula: Maturity Value
M.V. = P × n + I
