Accumulation of Regular Savings

This formula allows us to calculate an accumulated amount from a regular payment paid in arrears over a given period. 

 

 

 

An example:

£250 is invested into an account at the end of each year, at an interest rate of 6% per annum, for 8 years. What is the value of the account after 8 years?

-First we know that P = 250, r = 0.06 and n = 8

-We then place these figures directly into the formula:

-Therefore value of the investment after 8 years will be £2,474.37

d) £19,794.94

D)

We know that P = £2,000, r = 0.06 and n = 8.

Put these figures into the accumulation of regular savings formula.
