Hi Mo,
For the first option, you can use the formula:
A=P(1+i/n)^nt
Where,
A = final amount
P = initial deposit
i = interest (in decimals)
n = number of compounds per year
t = years
The second option is calculated by using
A=M(((1+i/n)^nt) -1)(n/i)
Where,
A = final amount
M = deposits per period
i = interest (in decimals)
n = number of periods per year
t = years
M = deposits per period
i = interest (in decimals)
n = number of periods per year
t = years
Hope this helps
