### Understanding Monthly Deposits

Any savings account consist of five important numbers. These are the following:**0)** The final lump sum you will receive at the end (often called the future value).**1)** The total amount you want to invest every month.**2)** The interest rate which you will receive on your deposits.**3)** The number of years the money will be in the bank for.**4)** The number of years it will take for you to have saved a certain amount.

Lets assume you want to save £150 a month for 3 years in an account that offers 5.8% interest a year.
