#### Formula:

f = a × ( ( i / 100) / ( ( ( 1 + ( i / 100 ) )^{n}) - 1) )
**Where,**
f = Required Payment
a = Total Accumulated
i = Interest Rate
n = Payment Period

### Example:

Calculate sinking fund required for the total accumulation fund of Rs.50,000, interest rate of 2% and the payback period of 12months.

#### Solution:

Sinking fund (f) = 50000 × ( ( 2 / 100 ) / ( ( (1 + (2 / 100 ) )^{12}) -1) )

= Rs.3727.97
