Formula to calculate accumulated amount = P*(1+r)^n

Here P is initial deposit amount, r is interest rate and n is number of year.

If interest rate increases then accumulated amount also increased.

If duration in years ( time) increases then also accumulated amount increased

So higher interest rate , higher accumulated amount

and higher years higher accumulated amount
